ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.
Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:
  • Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.
  • Instant operations: Aryacoin makes it quite easy for you to use your digital wallet and perform various operations with it.
  • Safe and secure: all your data is stored encrypted and can only be decrypted with your private key, seed, or password.
  • Strong security: The system has no control over your wallet. You are 100% in charge of your wallet and funds.

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
  • The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
  • The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
  • The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
  • There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
  • The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
  • The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.
Lessons learned?

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.
Lessons learned?

Weekly Update: First ParJar Pilot Class, Constellation partners with Chainlink, $BAT on 2gether, Pynk on BlockMAG... – 11 Oct - 17 Oct'19

Weekly Update: First ParJar Pilot Class, Constellation partners with Chainlink, $BAT on 2gether, Pynk on BlockMAG... – 11 Oct - 17 Oct'19
Hi everyone! Here’s your week at Parachute + partners (11 Oct - 17 Oct'19):

The first ParJar Pilot Class is officially off to a roaring start with 5 amazing projects and their communities. Here’s to a great future. This was the perfect occasion to announce a ParJar Battle Royale for our ParJar Pilot partners. Blood will be spilled next week. Pow! ParJar now has almost 20k active users. It works in 400+ communities and has seen 400k+ transactions. Say what! Par4Par lottery entered stage 5 this week. The stakes are even higher. 250k $PAR in prizes. Dang! Reflecting on Vitalik Buterin’s observation, Cap says: “...we’ve done things in reverse here at Parachute - we grew an amazing community around exploring ideas and built our tech to meet what they needed”. What are your thoughts on buying houses for USD 1 each in an Italian town for building the Parachute village? Cap’s recommendation. Haha.
Andy’s Advent calendar. Each window is a 16.9 oz can of beer. Sweet!
We saw Tiproom become the 17th most active group on Telegram a few weeks back. Well, hold on to your pants because it is now the 12th most active group. Whoa! A big reason for the group’s constant buzz are the amazing trivias hosted by the TTR crew. This week was no different. Doc Victor’s Sunday medical trivia had 8 Qs, 3k $PAR each. This was a quiz with a twist. In Doc’s words: "..beware, in each question they will have to diagnose a case based on symptoms and signs that I will give them". Noice! Charlotte’s Tuesday Trivia had 10 questions with a 25k $PAR prize pool. Another trivia by Victor (not the Doc) had another 10 Q’s, 2500 $PAR each. Listened to the TTR theme yet? DJ Jose in da house with a rocking theme. Wicked! Congratulations to Mario for winning the pet contest in TTR. Sebastian made a compilation video of all the entries. Awww!
Let’s see if Cap’s guerrilla marketing at Burger Joint in NYC gets us a new Parachuter
Victor’s Friday trivia at aXpire was the usual 10 Q, 100 $AXPR per Q affair. And like always, super duper fun! If you missed news from Week 41 at aXpireverse, Joakim’s got your back. Check out his video to catch up. CEO Gary Markham travelled to India this week to prepare for the Bilr release. Click here to track the latest 20k $AXPR burn.

The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Events

Attended:
For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning)
The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)

Media

Decred Assembly episode 21 is available. @jy-p and lead dcrwallet developer @jrick discussed SPV from Satoshi's whitepaper, how it can be improved upon and what's coming in Decred.

Community Discussions

Community stats:
Comm systems news:
After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:
Highlights:
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.
Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.
An unusual event was the chat about double negatives and other oddities in languages in #trading.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

Weekly Update: Mycro on ParJar, PAR on MetaMorphPro, new customer for Resolvr, 1UP on IDEX... – 19 Jul - 25 Jul'19

Weekly Update: Mycro on ParJar, PAR on MetaMorphPro, new customer for Resolvr, 1UP on IDEX... – 19 Jul - 25 Jul'19
Heya everyone, looks like we are in for another round of rapid catch ups on the weekly updates. Haha. Here's another exciting week at Parachute + partners (19 Jul - 25 Jul'19):

In honour of our latest partnership with Silent Notary, this week we had an SNTR Parena. Richi won the finale to take home a cool share from the 1.5M SNTR pot. The weekly Parena had a 100k PAR pot. McPrine took home the lion’s share by beating Ken in a closely fought finale. In 8 months since ParJar started, we are now at 12k users, 190k transactions and 200+ communities. Cap says: “…to put it into perspective - June 18th we were around 100k transactions and 9 k users. A month later we’ve added 3k new users (33% growth) and 80,000 new transactions”. Freaking amazing! And thank you for the shoutout aXpire! MYO (Mycro) was added to ParJar this week. And their community started experiencing the joys of tipping.
Lolarious work by @k16v5q5!
Last week MetaMorphPro did a Twitter vote to list new projects. Turns out Parachuters did PAR a solid. Woot woot! The first ever official TTR shirt is already live in the Parachute shop. Alexis announced the start of a shirt design contest to add to the TTR shirt inventory. Ian’s art quiz in TTR this week saw 25k PAR being given away to winners. Victor’s quiz had another 25k PAR pot for the winners. And Unique’s Math quiz in TTR was a 50k PAR extravaganza. All in all, 100k PAR won in quizzes in TTR this week. Sweet! Cryptonoob (Tom) set up a survey this week for “..for people who are interested in Crypto but don't know where to start..” for his work on the Parachute app UX. We all know how much Gian loves the reality show Big Brother. So we saw a new take on his Tuesday fun events. Mention your favourite reality show and what it’s all about to get some cool PAR. Yay!
A PAR coaster makes its way from design to final product in @k16v5q5’s workshop
Chris’ Golf tourney contest resulted in no winners since there were no correct guesses. So he decided to give out fun prizes instead: like Jason for coming last, Win for a “hilariously bad guess” of 100 strokes for the champions total score etc. Haha. However, there were a few top prize winners as well. LordHades, with a tournament score of 1968, took home 50k PAR as grand prize. Neat! Ali, Hang, Clinton and Tony came in close at 2nd to 5th positions. Congrats! And with that, Chris announced the start of another contest: Premier League Challenge for Parachuters (Entry code: x0zj2d) with an entry fee of 5000 PAR each. Prize pool yet to be announced. Jason is still in the lead this week in the Big Chili Race at 47 cm. Not much change either in the other plants. Slow week at Chili land.
Ric getting in on that sweet Parachute merch
Last week we shared that AXPR got listed on Binance Dex. The ERC20-BEP2 conversion bridge went live this week. Learn how to convert your ERC20 tokens to the BEP2 variant from the available how-to guides (article/video/gif). To mark the occasion, aXpire gave away a ton of BNB in an easter egg contest plus a 1% AXPR deposit bonus to folks who started using the bridge. Remember, we had mentioned that the reason for the weekly double burn of AXPR will be revealed this week? Well here it is. Resolvr onboarded a new client: HealthGates. More fees, more burn. Read more about it here. Woot! Victor hosted a trivia like every week on Friday at aXpire for 1000 AXPR. 10 questions. 100 AXPR each. Nice! Catch up on the week that was at aXpire from their latest video update. 2gether was selected as one of the top 100 most innovative projects by South Summit this week. Cryzen now built a Discord-Telegram chat bridge so that anything posted in either platform gets cross posted on the other. The latest WandX update covers the dev work that’s been going on for the past few weeks – support for Tezos wallet, staking live for Tezos, Livepeer and Loom etc.
2gether on South Summit’s honour roll
BOMB community member rouse wrote a quick script on how to identify and avoid common crypto scams. Have a read. As BOMB says, “Stay vigilant and always verify”. Last week's giveaway for the top lessons shared by entrepreneurs had so many good entries that the final list was expanded to 19 winners. Awesome stuff! Zach’s latest article on the difference between BOMB and BOMBX explores both the basic and the more complex distinctions. Switcheo’s introductory piece on hyperdeflationary tokens also talks at length about the BOMB project. Zach also announced the start of the Telegram Takeover Challenge this week – get new communities to experience ParJar and BOMB and earn some cool BOMB tokens in return. Win win! In preparation for the integration of the SMS feature in the Birdchain app, the team released an article on some key statistics. Here’s a video from Birdchain CEO Joao Martins discussing the feature. The latest Bounty0x distribution report can be found here. Also, check out a shoutout to the platform in this NodesOfValue article on bounty hunting opportunities.
Start of beta testing for SMS feature in Birdchain
The ETHOS Universal Wallet now supports Bitcoin Cash and Typerium. Following ETHOS’ listing on Voyager, it will also become the native token on Voyager. Switch continued its PR campaign with cover pieces on Yahoo, CCN and DDFX this week. Altcoin Buzz has a section on its site named “Community Speaks” where members of a crypto community share updates on a project they support. This week, Fantom was featured in this section. V-ID is the latest project using Fantom’s ERC20-BEP2 bridge for listing on Binance Dex. Big props to FTM for opening it up to other projects. FTM got listed on Probit and Airswap. FTM can also now be used as collateral for borrowing on the Constant platform. The Fantom Foundation joined the Australian Digital Commerce Association which works on regulatory advocacy in blockchain. This was also a perfect setting for the Fantom Innovation Labs team to attend the APAC Blockchain Conference in Sydney. Here’s a report. In this week’s techno-literature, have a read of the various Fantom mainnets and the TxFlow protocol by clicking here and here respectively.
Another proposed token utility of ETHOS
Uptrennd’s 1UP token was listed on IDEX this week. To put it simply, the growth at Uptrennd Twitter has been explosive. Check out these numbers. Awesome stats! This free speech vs fair pay chart shared by Jeff explains why the community backs the platform. About 96% of 1UP issued this week has been used to level up on Uptrennd. Want a recap of the latest at Uptrennd? Click here. Crypto influencer Didi Taihuttu and his family (The Bitcoin Family) joined the platform this week. Congrats once again to Horizon State for making it to the finals of The Wellington Gold Awards. Some great networking opportunities and exposure right there. If you have been lagging behind on HST news, the latest community update covers the past month. We had also mentioned last week that Horizon State is conducting a vote for The Opportunities Party in New Zealand. Here’s a media report on it. Catch up on the latest at District0xverse from their Weekly and Dev updates. The Meme Factory bot was introduced this week to track new memes and marketplace trends on Meme Factory. The HYDRO article contest started last week was extended to the 27th. 50k HYDRO in prizes to be won. Noice! Hydrogen got nominated as a Finalist to the 2019 FinXTech Awards. HYDRO was also listed on the HubrisOne wallet this week. And finally, here’s a closer look at the Hydro Labs team. The folks who make the magic happen. Sup guys!
The Parachute Big Chili Race Update – Jason at 1st, Sebastian at 3rd
And with that, we close for this week at Parachute and partners. See you again with another weekly update soon.

Lisk Highlights weekly roundup February 9th 2019.

Hello everybody. The LISK project and it's enthusiasts are always busy, and this week past has certainly been no exception.
Seeing is believing, so here is a recap of the highlights and interesting items from the past week on the LISK subreddit and beyond.....
 

Lisk's 11th LIP – Some Viewpoints on the Proposal to Change to one Vote Per Account.

I am sure you are all aware by now that HQ has just opened the discussion for their 11th LIP (Lisk Improvement Proposal) dealing with the "change to one vote per account in our DPoS". A thread was started on the Lisk subreddit announcing this LIP content and it provoked a lot of intense debate.
This LIP of course is for now just a proposal by the Lisk project team, and it should create discussion around what is best for the network. HQ advise that any interested community members should join the conversation by signing up to the LIP mailing list HERE. Lightcurve science team member Iker posted "Hey guys, we are looking forward to your contributions regarding this and other proposals. We will check all the community inputs in the mailing list.
Community Lead of the Lisk project, Mat Piaggi, produced a summary of the initial discussion on the Lisk Chat channel regarding this latest LIP. It features Iker from the Lisk science team and Chief R&D Officer and Co-founder of GNY, Richard Jarritt. You can read it HERE
 

Lisk Sidechain Project's CEO Attends Meeting With the EU Commission.

Christian Junger, CEO of the MADANA project recently met with Dr. Florent Frederix, a Cybersecurity expert from the European Commission in Brussels. I have heard that they discussed eprivacy, and cybersecurity of course. The importance of GDPR compliant technology for a more privacy-driven business world was chief among the talking points with MADANA being touted as one of the suitable project to uphold this imperative. It is no surprise so that the MADANA project is due to be one of the first major dApps to be built on a Lisk sidechain. This platform for data analysis using Blockchain technology allows participants to get in on the data market with their own data, whilst simultaneously preserving their privacy by design. The MADANA project has closed its pre-sale and is now preparing for its main sale
You can view an image of Christian's meeting in Brussels HERE.
 

LISK Sidechain Project's Founder Releases Three Exciting Pieces of Development Info.

You are all probably aware of GNY.io, the team bringing Machine Learning to Lisk via the sidechain LML (Lisk Machine Learning). Well, Chief R&D Officer and Co-founder of GNY, Richard Jarritt, in conversation with the projects followers on the GNY telegram dropped three exciting pieces of info over the the last few days.
 
1. Low fees.
The development team, which includes head of blockchain development, Leo Liang (known from the Asch decentralized application platform), have concluded their design where the Machine Learning data will be written into a contract. This is created with a low fee and then the Machine Learning reply (the prediction) is returned with another contract.
 
2. Timescale.
The team are aiming to get this Machine Learning and codebase integration completed by the month of March.
 
3. Unique.
You may may have seen blockchain before..... you may have seen Machine Learning before..... You may have even seen blockchain and Machine Learning combined before, however no competitors as yet have implemented or even attempted such a system where all the Machine Learning is done on chain, so data does not leave the security of the chain.
Plus the Machine Learning script does not grow exponentially. It is specifically coded to shed unneeded weight and prune off information, so that the data does not become too large for the chain. With each block, GNY's machine learning system is reading past data and the current data inputting into the block. It then makes a note of the pruned output, which is included in a contract for the next block.
The GNY universal Beta Api plug-in update is out now and testing is welcomed for commercial developers aiming to work with Machine learning and blockchain. You can visit Github to view the steps to run it HERE.
 

Lisk Play Prize Pool Swells and Another Lisk Game is On the Horizon.

A new community contest created by Lemii is receiving a great deal of support from the Liskers at large. Lisk Play is fun tool enabling simple contests to be played for a nominal amount of LSK. It's aim, besides bringing community together with fun, is to showcase a simple use case for transaction fields in explorer such as time, date, message, and so on with trivial value transactions. This is entirely a community initiative and has no affiliation to Lisk HQ, Lightcurve or the Lisk Foundation.
The first engagement of Lisk Play is a contest where the goal is to predict the opening price of Bitcoin as at 00:00 on the 1st of March 2019. Entering the competition costs 1 LSK and the closest prediction wins the sum of all LSK collected plus a top up fund kindly donated by stellardynamic of www.liskusa.io
The prize pool has now swelled to 120 LSK. You have to get moving though to enter as the deadline for all predictions is February 16th. You can check it out HERE.
In my opinion Lemii is to be commended for the work he has put into this project alongside his consultants Crosssy, Maul, Lisk.ftw, and Sexor (minions).
 
Now to the other Lisk game that is upcoming. My sources tell me that a Telegram contest is being worked on at present. I believe it will take the form of a treasure hunt type contest with hints given that will lead the lucky winnes to a cache of LSK. Sounds good? Of course it does. I will have more on the game in a short while.
 

LISK Videos around the World: Misss Bitcoin.

Dutch crypto Youtuber "Misss Bitcoin" released a new English language video titled "TA MONDAY | Technical Analysis on Bitcoin, Litecoin & Lisk". Misss Bitcoin AKA Maddie describes herself and her channel as follows..... "Seven years ago I became enthusiastic about Bitcoin, Cryptocurrencies and especially charting. I fell in love with the charts but besides that I’m still super excited about what the cryptocurrencies will bring us in the near future. I’m honored to be a part of the revolution and I would like to take you with me on this journey. Within this expanding crypto universe there is still so much to learn and I want to share this with everyone that is interested in (trading) cryptocurrencies".
She says she loves Lisk and it is one of her one of her favorite cryptos. Analysing the Binance chart in the video she says that although it not a very positive chart currently, she is still very positive for Lisk. She goes on to say that the next 10 to 14 days will be crucial to see if it LSK tests the bottom of its current chart.
I took the liberty of cropping her current video to allow you get straight to the Lisk TA. You can view it HERE. See what you think and don't forget to give the Youtube channel of the original poster a thumbs up if you find it of value.
 
That's it for the recap of the weeks highlights. I hope it brought you up to speed with all the weeks good news.
These highlight posts also go out daily on the….
LISK Highlights exclusive Telegram group
LISK Highlights Twitter
The highlights are also included in my weekly roundup on the LISK Highlights Medium account and the Bitcoin talk forum's LISK thread, so keep an eye out for them on these outlets also.
 
Keep the faith Liskers! 👍

Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable

Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable
It’s a balmy 80 degrees on a mid-December day in Singapore, and something is puzzling Allen Day, a 41-year-old data scientist. Using the tools he has developed at Google, he can see a mysterious concerted usage of artificial intelligence on the blockchain for Ethereum. Ether is the world’s third-largest cryptocurrency (after bitcoin and XRP), and it still sports a market cap of some $11 billion despite losing 83% of its value in 2018. Peering into its blockchain—the distributed database of transactions underpinning the cryptocurrency—Day detects a “whole bunch” of “autonomous agents” moving funds around “in an automated fashion.” While he doesn’t yet know who has created the AI, he suspects they could be the agents of cryptocurrency exchanges trading among themselves in order to artificially inflate ether’s price.
“It’s not really just single agents doing things on their own,” Day says from Google’s Asia-Pacific headquarters. “They’re forming with other agents to have some larger group effect.”
Day’s official title is senior developer advocate for Google Cloud, but he describes his role as “customer zero” for the company’s cloud computing efforts. As such it’s his job to anticipate demand before a product even exists, and he thinks making the blockchain more accessible is the next big thing. Just as Google enabled (and ultimately profited) from making the internet more usable 20 years ago, its next billions may come from shining a bright light on blockchains. If Day is successful, the world will know whether blockchain’s real usage is living up to its hype.
Danish researcher Thomas Silkjaer is using Google's BigQuery to map publicly available information about XRP cryptocurrency addresses. The craters represent some of cryptocurrency's largest exchanges.
Last year Day and a small team of open-source developers quietly began loading data for the entire Bitcoin and Ethereum blockchains into Google’s big-data analytics platform, BigQuery. Then, with the help of lead developer Evgeny Medvedev, he created a suite of sophisticated software to search the data.
In spite of a total lack of publicity, word of the project spread quickly among crypto-minded coders. In the past year, more than 500 projects were created using the new tools, trying to do everything from predicting the price of bitcoin to analyzing wealth disparity among ether holders.
When it comes to cloud computing, Google is far behind Amazon and Microsoft. Last year Google pocketed an estimated $3 billion in revenue from cloud ser­vices. Amazon and Microsoft, meanwhile, generated about $27 billion and $10 billion, respectively.
Day is hoping that his project, known as Blockchain ETL (extract, transform, load), will help even the playing field. But even here Google is trying to catch up. Amazon entered blockchain in a big way in 2018 with a suite of tools for building and managing distributed ledgers. Microsoft got into the space in 2015, when it released tools for Ethereum’s blockchain. It now hosts a range of services as part of its Azure Blockchain Workbench. But while Amazon and Microsoft are focusing on making it easier to build blockchain apps, Day is focusing on exposing how blockchains are actually being used, and by whom.
“In the future, moving more economic activity on chain won’t just require a consensus level of trust,” says Day, referring to the core validating mechanism of blockchain technology. “It will require having some trust in knowing about who it is you’re actually interacting with.” In other words, if blockchain is to go mainstream, some of its beloved anonymity features will have to be abandoned.
A native of Placer County, California, Day got his first computer at the age of 5 and a few years later started writing simple programs. A fascination with volcanoes and dinosaurs turned his interest to life sciences, and he ultimately graduated from the University of Oregon with a dual degree in biology and Mandarin in 2000. From there he headed to UCLA to pursue a doctorate in human genetics and helped build a computer program to browse the genome.
It was at UCLA where Day began relying on distributed computing, a concept that is core to blockchains, which store their data on a large network of individual computers. In the early 2000s Day needed to analyze the massive amounts of data that make up the human genome. To solve this problem he hooked many small computers together, vastly increasing their power.
“Distributed-systems technology has been in my tool kit for a while,” Day says. “I could see there were interesting characteristics of blockchains that could run a global supercomputer.”
Hired in 2016 to work in the health and bio­informatics areas of Google, Day segued to blockchains, the hottest distributed-computing effort on the planet. But the talents he had honed—sequencing genomes for infectious diseases in real time and using AI to increase rice yields—were not easily applied to decoding blockchain.
Before Day and Medvedev released their tools, just searching a blockchain required specialized software called “block explorers,” which let users hunt only for specific transactions, each labeled with a unique tangle of 26-plus alphanumeric characters. Google’s Blockchain ETL, by contrast, lets users make more generalized searches of entire ecosystems of transactions.
To demonstrate how customers could use Blockchain ETL to make improvements to the crypto economy, Day has used his tools to examine the so-called hard fork, or an irrevocable split in a blockchain database, that created a new cryptocurrency—bitcoin cash—from bitcoin in the summer of 2017.

This particular split was the result of a Hatfield and McCoy “war” within the bitcoin community between a group who wanted to leave bitcoin as it was and another who wanted to develop a currency that, like cash, was cheaper and faster to use for small payments. Using Google’s BigQuery, Day discovered that bitcoin cash, rather than increasing so-called micro-transactions, as the defecting developers claimed, was actually being hoarded among big holders of bitcoin cash. “I’m very interested to quantify what’s happening so that we can see where the legitimate use cases are for blockchain,” Day says. “Then we can move to the next use case and develop out what these technologies are really appropriate for.”
Day’s work is inspiring others. Tomasz Kolinko is a Warsaw-based programmer and the creator of a service that analyzes smart contracts, a feature of certain blockchains that is designed to transparently enforce contractual obligations like collateralized loans but with less reliance on third parties, like lawyers. Kolinko was frustrated with his blockchain queries.
In December, Kolinko met Day at a hackathon in Singapore. Within a month of the meeting, Kolinko was using Google’s tools to search for a smart contract feature called a “selfdestruct,” designed to limit a contract’s life span. Using his own software in conjunction with Day’s, Kolinko took 23 seconds to search 1.2 million smart contracts—something that would have taken hours before. The result: Almost 700 of them had left open a selfdestruct feature that would let anyone instantly kill the smart contract, whether that person was authorized or not. “In the past you couldn’t just easily check all the contracts that were using it,” Kolinko says. “This tool is both the most scary and most inspiring I’ve ever built.”
Day is now expanding beyond bitcoin and ethereum. Litecoin, zcash, dash, bitcoin cash, ethereum classic and dogecoin are being added to BigQuery. Independent developers are loading their own crypto data sets on Google. Last August, a Dutch developer named Wietse Wind uploaded the entire 400 gigabytes of transaction data from Ripple’s XRP blockchain, another popular cryptocurrency, into BigQuery. Wind’s data, which he updates every 15 minutes, prompted a Danish designer named Thomas Silkjaer to create a heat map of crypto flows. The resulting colorful orb reveals at a glance more than a million crypto wallets, including big ex­changes like Binance and London’s crypto debit card startup Wirex, which are neck deep in XRP transactions.
“Google has been a bit of a sleeping giant in blockchain,” says BlockApps CEO Kieren James-Lubin, who is partnering with Google to sell enterprise blockchain apps. In addition to Day’s work, Google has filed numerous patents related to the blockchain, including one in 2018 to use a “lattice” of interoperating blockchains to increase security, a big deal in a world where untold millions of crypto have been stolen by hackers. The company is also pushing its developers to build apps on the Ethereum blockchain, and Google’s venture arm, GV, has made a number of significant investments in crypto startups.
The giant, it seems, is waking up.
