Barterlly is an automatic escrow service for fast & secure OTC trades ->Note: Barterlly is currently in beta!<- WHAT IS BARTERLLY AND WHAT PROBLEM DOES IT SOLVE?Barterlly is an over the counter (OTC) cryptocurrency swap service that allows direct trading without human escrow. Let's say that Alice has 800 Ravencoin (RVN) and Bob has 450 EnJin (ENJ erc20) and they want to swap them, how can they proceed? They don't know each other. Neither can't risk to send first. There are many stories of people getting scammed while trading privately. They will have to find someone with an excellent reputation who will act as escrow. This is an inconvenient procedure that takes time, risk and high fees. Barterlly offers a fast and simple alternative: Alice can setup a private trade of 800 RVN <-> 450 ENJ and send the link to Bob. Once both sides have deposited their coins, Barterlly makes the swap (or refunds if anything goes wrong). HOW DOES IT WORK?Barterlly uses an automated escrow technology to create blockchain addresses on the fly and check / transfer funds automatically allowing users to swap coins in a safe way without having to trust anyone else than the platform. WHAT COINS ARE SUPPORTED? Bitcoin and most Bitcoin-based coins, Komodo and Komodo assetchains, Ethereum and Erc20 (soon). Many more coins will be added in due time. An updated list will be available soon. HOW TO SETUP A SWAP?After registration you can setup a swap by filling a form with the type and amount of coins to be traded, the refund and receiving addresses. Then send the private link to your counterparty. He will have to complete his part and then both of you can proceed to deposit the coins. (Note: in current implementation both parties need to send the exact amount required, even in separate transactions. Sending coins in excess will stuck the swap and you need to delete, wait for refund and start over). WHAT IS A PUBLIC OFFER? In alternative you can use Barterlly to setup public offers that anyone can search and accept. You don't need to deposit the coins in advance and the offer automatically expires after ~48 hours if no one takes it. AFTER SENDING HOW MANY CONFIRMATIONS ARE NECESSARY?That depends on the specific coin: Komodo and other blockchains using dPoW are fully confirmed after 1 notarization, for all other coins (that don't support dPoW) fixed values are set. HOW LONG DOES A REFUND TAKE Barterlly's engine handles refunding automatically, within 36 hours at the latest. In case of delay please contact support. DOES IT SUPPORT ANONYMOUS TRANSACTIONS? Barterlly supports the private addresses used by privacy coins such as KMD, ZEC, PIVX, ARRR. You can enable this option by clicking the checkbox when accepting or publishing a swap. HOW MUCH IS THE FEE?Barterlly charges a 1% fee on both sides of the trade ARE KYC/AML REQUIRED?No kyc/aml is required for daily trading amounts below 10k Usd WHY SHOULD I USE BARTERLLY RATHER THAN THE OTC DESK OF IMPORTANT EXCHANGES?Only with Barterlly you can trade privately with a specific counterparty. Moreover OTC desks require a minimum trading value of many thousands USD. Barterlly on the opposite is built for small swaps and itwill support smallcap coins. HOW TO REQUEST A COIN LISTING?Please fill the following form with the coin informations: https://barterlly.typeform.com/to/iqpS1HHOW TO CONTACT SUPPORT?For any help, suggestion or request please fill the contact form in your account, under the Help&Support tab ABOUT BARTERLLYBarterlly was created in order to stop people from being scammed in OTC trades. Barterlly's office is based in France and registered as a simplified joint stock company number 849 387 915.

Hello guys can anyone review and poke holes in the below solution to the N@S and WS for Proof-of-Stake chains? This has been proposed by Mike Toutonghi, developer of Verus, and announced a few days ago. I'm not a dev but I've trying to raise awareness and ask for feedbacks, unfortunately it's hard to get it through the noise. First a little background: Crypto Conditions, or CC, are utxo-based smart contracts for Komodo-based blockchains. The specifications were created by Ripple engineers and proposed to IETF as a standard. Komodo is a Zcash fork and the first blockchain to implement them, also adding more enhancements and creating a way to make custom consensus rule changes. Verus is a fork of Komodo and both projects are collaborating with respective enhancements. The lead developer of Verus is Mike Toutonghi as I wrote above. Maybe you've heard the name because he's the ex CTO of Parallels and the chief architect of .NET when he worked at Microsoft. This solution is going to be live on mainnet on october 28th when Verus also upgrades to Sapling. There's not a paper yet but it has been explained in a Medium article that I will quote here (omitting the first half that explains what N@S and WS are in layman terms). Verus Crypto Conditions
To effectively use CCs for Verus’ purposes, Mike extended some of the capabilities of Crypto Conditions, particularly adding more meta data definitions and allowing CC transactions to act more like “normal” transactions. With the modified CCs Verus is able to implement powerful functionality that extends the flexibility and resultant power of the Verus blockchain in preparation for PBaaS and the services which will be able to be coded into blockchains in the future.
Stake Guard is the first Verus Crypto Condition to be released and it’s what solves the “nothing at stake” problem and performs the “magic”.
Stake Guard — The Proof of Stake Crypto Condition
This new CC which Verus has developed and is adding to the blockchain, works in conjunction with a newly modified signing script when staking and spending a reward.
The result is a blockchain-level Crypto Condition which handles all staking transaction spends, either processing them as usual for normal shakers, or allowing any cheated stake transaction containing its stake block reward to be spent by anyone who can prove its indeed a cheaters stake. No double spending occurs at any point, to cheat the cheater had a real stake plus additional cheat attempts at any given block. Only the legitimate stake reward can be spent when proven.
Here’s how it works.
1. When staking a new block, a new format of transaction called a Staking Transaction is generated. This transaction format is enforced and utilizes the Stake Guard at the minting of the new block. It contains more meta data, such as the public key of the staker who signed it, the UTXO, the block height, and previous block height.
2. If a cheater has tried to stake on more forks at the same block height, that cheat attempt is also recorded. Anyone scanning the blockchain can see it and verify that it’s indeed a cheat attempt, as the data is there immutably and without the ability to manipulate things like UTXO or information about the blockchain at the time of the stake.
3. For the community, this is an opportunity of 100 blocks to look for any such cheat attempts and tuck them away to take at that cheat transactions maturity. Also important to note: UTXO can only be spent once, so there’s no risk of double spending at this point. And the cheater’s one valid block reward is able to be taken by anyone who sees it and spends it at block maturity.
4. After 100 blocks when any block reward is spent, it passes through the Stake Guard Crypto Condition script which evaluates the spend transaction for 1 of 2 things:
Condition a — Is this spend being signed by the Public Key which staked it?
Condition b — Is proof presented in the OP_RETURN that this is a cheater’s block reward?
Result— Depending on one of the two conditions being met, Stake Guard will validate or reject the spend.
5. Condition a: if a normal staker is trying to shield their stake reward, their public key is being passed automatically to Stake Guard which compares it to the public key in the meta data of the stake transaction on the blockchain. They match, so it signs it as normal and the staker has their reward.
6. Condition b: if the public key of the spender does NOT match the original staker public key, Stake Guard verifies that the cheat transaction proof has been submitted in the OP_RETURN.
7. The proof of a cheated transaction, the data bits packed up from that duplicate stake transaction which the Cheat Hunter found, is passed in an OP_RETURN and the Stake Guard CC evaluates and confirms that it is indeed a verifiable cheated transaction. It does this by comparing the matching UTXOs of the legitimate and cheated staking transactions, their respective previous block heights, and their respective block heights at the time they were generated. In fact, this is another case of validating signatures to cryptographically verify that the stake transaction was properly signed, meaning proof of cheating cannot be forged.
8. If Stake Guard confirms the cheat transaction is indeed a cheat, the spend of the cheaters stake reward at the time of the cheat, is signed using the Stake Guard’s key and spent to the shielded address provided by the person who claimed the cheater’s reward. The wallet of the person who found the cheat reward is paid the block reward and it disappears from the cheater’s wallet.
Decentralized Anti-Cheat Staking
As mentioned above, for legitimate stakers the Stake Guard CC will function normally, signing the coinbase reward transaction when they spend it with their own Public Key…all in the background and at the blockchain level.
If, however, the 1 of 2 evaluation sees the public key of the person trying to spend it doesn’t match that of the original staker it simply verifies the person trying to take the free money from the cheater has proven that this is indeed a cheated transaction which they discovered and if so, will let them take it.
This can be done by anyone who knows how to pack up the data after scanning and finding cheat attempt staking transactions…but will also be implemented into the mining software by Verus to perform the attempted spend of the cheaters reward block when mining at the block where that cheat reward matures.
No Incentive to Cheat
The cheaters one single legitimate reward block out of the two attempts they made to double spend, is no longer locked in to be spent by them alone. Anyone can now spend this by simply proving to the Stake Guard CC the verified cheat transaction hash in an OP_RETURN.
So, while even the cheater can try to run and grab it with the rest of the network, or try to spend it before anyone else, now the odds are stacked against them… and why even cheat? Afterall, there is no double spend available due to the fundamental way in which the blockchain is modified with this Stake Guard.
It simply makes no sense, using the same logic PoW uses, decentralizing the process of catching and being rewarded for finding cheat transactions by getting the cheaters reward, and makes legitimate staking more rewarding by itself. And if cheaters do try anyway, the legitimate staker has a better chance of even claiming those rewards which the system makes publicly visible.
Chain Power and Nonce
Another important change being implemented in this new Verus upgrade is moving away from Chain Work to what Verus is calling Chain Power. Chain Power is now replacing Chain Work, solving the threat of Weak Subjectivity.
Chain Work
Within chain work, the block index is a sequential index of block entries which “knows the height” of the chain. As you build and add blocks, you add the entry to the block index.
This way at any point you have a maintained value that reflects the chain work at that point. The Chain Work is normally a sum of the proof of work difficulty, for any set of blocks.
Chain Power
Chain Power is a 50% of one value and 50% of another value comparative calculation. It’s a tracking of both Work and Stake.
Chain Work is based on a number that everyone calculates the same on every block. You can’t be completely sure of the time and date someone makes a block. So on a very small scale someone could make it seem like they had a little more work, just for a moment.
With Chain Power Verus will not just take the Proof of Stake difficulty, it also takes the actual nonce random amount of work from every block, adding it as additional Stake Power. This way no two blocks will match and there’s no way to manipulate this value.
This nonce “work” number will be added to the Stake Difficulty. Someone can’t just grind away at this as a result.
And so, Verus, as a “hybrid” combination of Proof of Stake and Proof of Work, will now have a value which is calculated from a comparison between Stake and Work. If stake power is at 20% and work power is at 30% for example, that is a sum total of 50% Chain Power.
What this means is, to attack the blockchain in a way in which weak subjectivity is a problem, the attacker would need to have more than 50% of either staking or mining power given the above example.
The implications of this are massive, making a hybrid Chain Power blockchain like Verus a weak subjectivity resistant chain and adding capabilities that far outweigh the security of traditional Chain Work in Proof of Work chains.
I also quote Toutonghi's direct reply to a question: Q. What are the weaknesses of your approach?
miketout:
That’s a great question. First, let me explain how it works. The nice thing about the solution is that it’s simple, similar to the Bitcoin protocol. There are no locked funds or voting pools. The premise is this:
The nothing at stake problem asserts that it is more profitable to sign all forks, as doing so, although bad for the network, can raise the chances of the validator earning the block.
If you make it always a statistically losing proposition to try to cheat by signing multiple forks, the nothing at stake problem goes away.
This is in contrast to the approaches to date, which generally want you to commit more stake in a way that can be slashed. Instead, it works like this… any transaction can win, and if so, it becomes the source of your staking transaction. Your wallet creates the staking transaction, which includes some information binding it to the specific block you are staking on, signs it to be able to spend its source, and puts it and the coinbase transaction in the block with certain matching information.
The coinbase reward transaction is the Stake Guard contract and will validate a spend for one of the following cases:
The spend is signed by the originally intended recipient of the coinbase transaction.
The spend is signed by the Stake Guard contract and contains a stake transaction spending the same source transaction and bound to another block of a fork.
That means that if someone cheats, the cryptographic proof of them cheating spends any reward they would have made to someone else, likely the miner of the block at which that coinbase matures. Meaning that there is something at stake if you cheat. You will make less, meaning most people won’t try it, and those who do will make money for everyone else.
I’m pretty hard pressed to come up with any fundamental weaknesses in the model, but for the implementation, one could argue that the rule that a cheat proof must be a transaction targeting the same or higher block height might let a few cheats go by. I’d still say that statistically, it will always be the wrong thing to do to cheat, and that I’d rather err on the side of false negative than false positive when dealing with people’s rewards. So what's your opinion? I wonder what Andrew Poelstra will say about it |

A short introduction to Supernet v2.3.1 What is Supernet?Supernet is a decentralized platform that acts as a middleman between different cryptocurrencies. It offers seamless and smooth interoperability and a common framework of development between several blockchain technologies. As a user you have access to all their innovations from one place. "In Crypto, the competition is not each other, it is fiat. If any Crypto does well, we all benefit." --jl777 Who is James?James, known as jl777, is the anonymous developer behind the Supernet project, an extremely gifted C developer with financial experience and a clear vision for the future of crypto. He created the MGW service that works on Nxt blockchain and his advices are often sought after from other crypto projects and he has collaborated, among others, with Nxt, Iota and Waves. Is Supernet a coin?No, it isn’t a coin but it also includes a coin, Komodo, among its many components. Komodo is a Z-Cash fork and many Supernet features will be relying on it. Does Supernet want to replace Bitcoin?No! Supernet is to a crypto like the internet is to a website, it doesn’t want to replace Bitcoin or any other coin. Quite the contrary, Bitcoin plays an essential part both as the main crypto unit of account and for securing the whole system with its hashrate. Supernet helps Bitcoin and the whole crypto ecosystem by uniting them in a common framework that leverages each other strength and specialization. Any supported coin can easily make use of each other features or use additional services built on top of the platform. What are the goals of Supernet?The first goal is to unite the fragmented crypto ecosystem against its true enemy: fiat money. The second one is to solve the main bottlenecks of crypto: scalability, speed, privacy and price stability. Supernet is not designed to replace Bitcoin or any other cryptocurrency, but to enable cryptocurrencies to compete more effectively with the fiat economy. ...to fully solve mainstream crypto use, you need to be able scale, price things in fiat, have it still be decentralized, privacy enhanced, etc... --jl777 How does Supernet plan to achieve such goals?Thanks to a combination of powerful features: Multiwallet- Supernet offers a fully featured multicoin wallet (Iguana) that supports both Bitcoin, Komodo and most other bitcoind compatibles (like Ltc, Doge, etc...)
...Iguana is the core of SuperNET platform. It implements many layers of functionality, starting with the bitcoin protocol, but all the way up to smartchains.--jl777 Untraceability- Iguana will offer 100% untraceability for Bitcoin and all other supported coins/assets, thanks to Z-Cash Zero Knowledge proofs used by Komodo. This specific feature is called Jumblr and it will allow Btc->Kmd->Btc mixing. Other advanced features will hide correlations and since the exchange is atomic there's no counterparty risk. This is the best possible technology available to protect one's privacy.
..because Komodo also interacts with our other services it is possible to use it to give privacy features for any other coin we support. In other words, you could send Bitcoins in and out of KMD to destroy its transaction track record. We will automate this process with a mixer called Jumblr. --Audo dPoW- Supernet uses Bitcoin hashrate to protect less secure coins by regularly notarizing an hash of their blockchain on Bitcoin, with the delayed-PoW consensus mechanism of Komodo. An attacker won't be able to change the history of a coin without first attacking Bitcoin as well. Both natively supported coins/chains or any external blockchain project can avail themselves of the notarization service. Bitcoin is by far the strongest and most secure coin, but it’s slow to evolve: dPoW allows Bitcoin to continue its slow pace, while allowing an entire ecosystem of innovative crypto solutions to benefit from its PoW expenditures.
...for other cryptocurrencies to become as secure as bitcoin they would have to secure their network with as large hashing power. However, this is not economically possible and would make the overall system, even more, energy inefficient. The solution would be to allow other cryptocurrencies to take advantage of bitcoin’s hashing power. --jl777 Pax- Supernet includes Pax, a decentralized pegged assets system without counterparty risk. Assets can be pegged to the main fiat currencies (Usd, Eur and other 30 fiats already supported). Pax enables locking funds to avoid price volatility or betting on short term market movements or longer term investing. First version is capped at 40k Usd but later versions (Pax2) will remove the limitations and add commodities (gold, oil, etc...) and indexes (Nyse, Nikkei, etc...) that will turn it into a full decentralized forex system with no kyc/aml. All pegged assets enjoy 100% z-cash untraceability and dPoW security.
...the aim of pax is not for speculation, but to provide something that has stable value that the mass market can understand and relate to. --jl777 InstantDEX- Supernet, thanks to dPoW and Iguana, creates a large network of Bitcoin-secured chains that can do atomic swaps with each other. Atomic means that you're trading the real coins (not a proxy token) and the trade is either fully executed or it isn't. This allows Instantdex: anonymous, instant, escrowless, decentralized exchange between all supported coins/assets against any other supported coins/assets (Bitcoin, Altcoins, Assets and all Fiat-money-pegged equivalents). The friction of these cross chain swaps is further reduced by “Liquidity Provider” nodes that can interface with centralized exchanges (anyone can be a LP and charge a small premium for this).
...DEX (short for InstantDEX) is the atomic cross chain swap that is built into Iguana, well, on top of the Iguana core. DEX will directly exchange crypto coins in your local wallet, so there is no need for any intermediary. You always control the coin. --jl777 Lchains- Supernet solves the problem of blockchain bloat thanks to the Ledgerchains: a very effective pruning technology that uses regular snapshots of current balances and a complex nest of hashes and dPow to make the pruned chains as secure and verifiable as the full ones. Blockchains will just grow linearly in size instead of exponentially.
...instead of just one hash for the latest block, Lchains have a dozen hashes for each subset of the ledger data, this means you can get the ledger components from a dozen different other nodes after making sure they are all in agreement and then reconstruct a specific Lchain ledger. --jl777 Blockchains, Assetchains, Smartchains- Supernet allows the creations of any custom coin or asset or programmable blockchain (Geckochains). All of them have 100% untraceability with z-cash technology and are fully secured by dPoW and atomically tradable on Instantdex. Assetchains are a special form of blockchain with fixed supply and built-in dPoW to KMD chain. They also have on-demand block generation, i.e. there is a block only if there are transactions. So they're designed for low volume usage. Geckochains are special blockchains that can be customized and programmed (at first in C++ and later in other languages) for any purpose. Since Geckochains are independent chains, if something goes wrong only that single chain is affected. An Assetchain, for example, is a type of specialized smartchain for assets: it has its own blockchain independent from the underlying platform, it create a block only if there's an actual transaction and dividends can be paid in Bitcoin or any other supported coin/asset. Then it's possible to create a Virtualchain that has no physical nodes and runs a Geckochain, i.e. Iguana full nodes will process the transactions and mine the blocks. Also Privatechain that is just a virtual chain with its own dedicated nodes using a real internet port.
...I have things setup so you can add new script opcodes, create a data overlay to encode an arbitrary command set, even add new network protocol messages. All directly into the smartchain. This is a compiled approach versus the interpreted approach that is used by the scripting smart contract systems. With a compiled approach, the developer just codes what the dapp needs and only what the dapp needs. Any language that creates linkable object files can be used, but of course I code mine in C. --jl777 Games- Supernet will use specialized smartchains and other features to support P2P sports betting and casino games, this includes a decentralized Poker game (Pangea) that uses provable random numbers and also a decentralized betting systems that allows individuals to make escrowed bets directly between each other. All of them take full advantage of the built in privacy features of Supernet.
I dont think there are any decentralized poker solutions that are released yet. Building on the SuperNET API, a lot of the privacy and payments are already taken care of. --jl777 ...and more!- The list is not yet comprehensive and the things that can be built over the Supernet framework are going to shake the cryptocurrency world. It will allow developers to build any sort of services and countless different solutions and specialized applications on top of the platform.
What is Iguana?Iguana is a new Bitcoin and multicoin wallet that serves as unified codebase for the Supernet platform. It has been written from scratch in C and it’s the first multicoin parallel syncing bitcoin protocol daemon, including RPC, that compiles to 2MB. It can synchronize at the max speed allowed by your internet connection and run 10+ coins all at the same time. Full Bitcoin synching (75GB) takes about one hour on top end machines. Coins can also be run in lite mode (basilisk mode) without blockchain download. Iguana will be available natively for all OS systems and in lite version for mobile or Chrome app. Iguana preview: Standard GUI: https://projects.invisionapp.com/share/WF8ST5V5JEasydex GUI: http://imgur.com/a/yOEBr How many coins does Iguana support?The first release will support Bitcoin, Komodo and many bitcoin rpc compatible coins. At this time Anoncoin, Bitmark, Carboncoin, Digibyte, Dogecoin, Earthcoin, Franko, Gamecredits, Komodo, Litecoin, Mazacoin, Namecoin, Syscoin, Unobtanium, Viacoin, VPNcoin, Zcash and Zetacoin are either working or in testing. More will probably be added before release. What is Bitcoindark?Bitcoindark is a privacy centered coin that was expected to be used by Supernet for some of its features but it’s going to be gradually phased out and fully replaced by Komodo. Thus references to Btcd in old Supernet related articles must be considered as pertaining to Komodo for the same purpose. What is Komodo?Komodo is a privacy centered coin with Zcash technology and a new delayed-proof-of-stake (dPoW) consensus mechanism that uses Bitcoin hashrate to secure itself and other coins. Like its predecessor, Komodo will also serve as underlying basis for the pegged asset system, for notarization and for many other Supernet features. What advantages other coins have to use the notarization service rather than making their own dPoW system? It costs a lot to make constant transactions to the Bitcoin blockchain and tx fees are expected to become more expensive in the future. It is a lot cheaper to do those transactions to the Komodo blockchain, as Komodo is a PoS coin with a lot lower tx fees. So it makes sense for all the other coins to use Komodo as intermediary between them and Bitcoin instead of directly using the latter. Since Komodo is the first one to implement this it will become the standard gateway for dPoW. Other coins will start using Komodo to secure their own blockchain, then it will create a lot of small transactions fees for Komodo. Part of those transaction fees will be used to pay for the bitcoin transaction fees and the system becomes self-sustaining. What is a Liquidity Provider?All new exchanges, both centralized or decentralized, suffer from the chicken and egg problem of not having enough liquidity to attract users and users don't like trading on exchanges that have very little liquidity. Supernet bypasses this problem by allowing any user to become a liquidity provider (LP), such users can interface with centralized exchanges with their personal APIs and offer liquidity. (and charging a small premium for doing so). Is a decentralized marketplace in the works? This feature is not currently planned by the Supernet team but other developers are free to create one. Supernet will offer all the tools necessary to built this type of service, thanks to Smartchains, API and fiat money pegs. How does Supernet helps Bitcoin scalability?Beside Lchains and other features, Supernet could help scalability through loosely coupled bitcoin compatible blockchains. If Supernet can connect many blockchains together in a hierarchy, it can scale up the max transactions capacity. If one blockchain can do ~100 transactions per second, then it can increase on-chain capacity by a hundredfold by connecting 100 blockchains together. ...there is so much talk about the scaling problem, but the answer is right in front of us. Just make 1000 chains, now you have 1000x the tx capacity. Make the tokens between these 1000 chains interchangeable, using something similar to the Pax gateway, which has smart sidchain type of behaviour. Really Pax is a full fledged Dapp in its own right as it is combining a realtime pricefeed with automated conversion/validation cross chain.--jl777 There is a coin that I’d like to see supported by Supernet, what can I do?It must be made a distinction between support in the multicoin wallet and support for the atomic exchange and other features. For the wallet, only coins that are Bitcoin forks or other simple bitcoind compatibles will work natively in Iguana. Other coins with substantial changes and/or special features can probably use Iguana as a GUI, with minor tweaks, but they must be run with their own native demon. Anyway a coin could require specific changes to Iguana GUI and coin developers are encouraged to get in touch with the Supernet community and study the appropriate solution to make their coin fully compatible. Coins based on completely different codebase (like Ethereum, Nxt, Waves, Byteball, etc...) can't work natively in Iguana and they would require a lot more work to just use it as a GUI. Again it's not impossible and coin developers are encouraged to study their own solution for Supernet integration. For the DEX feature, interoperability requires to make a 2of2 multisig using secp256k1 keypairs. Any non-bitcoin compatible coin that supports it can be integrated and traded with the decentralized atomic exchange (once the blackbox plugin setup feature will get implemented!). Given the great upsides of integration into the Supernet platform, all forward-thinking coin communities should put effort into achieving this purpose and it's up to them to offer bounties and coding contests for such work. The Supernet team is always available for support and questions in the official Slack but they can't integrate themselves all existing and new cryptos because main development has the highest priority. ...theoretically any coin that can do 2of2 sekp256k1 multisig can be a DEX compatible coin. --jl777 When is Supernet going to be released?After two years of tireless work a minimal version of Iguana is expected to be released 31 january 31, 2017. What is the timeline for the release of a fully featured Supernet?Supernet is a huge project with many long term goals and it’s impossible to offer exact dates. James (jl777) has written over 100k lines of code in the course two years and he had also to overcome many external obstacles while doing so. By far the greatest work has been the creation of a new optimized bitcoind implementation in C that is now Iguana. The other features have been coded at least at alpha stage. After Iguana release the development timeline will probably be: InstantDex, Pangea Poker, Pax2. Some features need that others be implemented first. While other features are less a priority. Thanks to the funds collected by Komodo Ico the development is expected to greatly accelerate in the course of 2017 and James will be able to focus on deep issues and important features. ...in 5 years, it should be fully integrated seamlessly wherever it makes sense to have crypto or privacy. The easier it is to use, the harder it is to create. --jl777 Useful links?The best way to stay updated with latest developments is by joining the Supernet Slack, channels #iguana #komodo http://slackinvite.supernet.org/http://coremedia.info/index.php/supernethttps://github.com/jl777/SuperNEThttp://docs.supernet.org/Komodo https://komodoplatform.com/https://bitcointalk.org/index.php?topic=1605144.0https://github.com/jl777/komodo |

Se uno volesse vendere e gestire professionalmente investimenti in vari assets virtuali, qualcuno è già a conoscenza di come si può inquadrare la cosa dal punto di vista della maf... ehm dello stato italiano?
Ho letto di Sim, Sicav, Sgr, etc... ci capisco ancora poco, a parte che per legge richiedono tutti grandi capitali e autorizzazioni. Mi chiedo se c'è un modo di partire in piccolo? Dato che la natura delle cripto è ancora indefinita dal punto di vista legale, forse c'è spazio di manovra ma vorrei evitare evitare rogne future.
Nello specifico l'idea sarebbe di investire il capitale dei clienti in certi assets che pagano dividendi mensili, trattenendo una % dei dividendi come compenso.

http://www.laht.com/article.asp?ArticleId=2390219&CategoryId=12396Japan Discusses Common Rules for Virtual Money with U.S. and China
TOKYO – Financial authorities of Japan, the United States and China plan to establish joint regulations to prevent use of virtual currencies, such as bitcoin, to finance terrorism and other illegal activities, Japanese newspaper Nikkei reported on Friday.
The three countries have pushed for an initiative in the 31-member Financial Action Task Force, FATF, to approve the guidelines for regulating virtual currency, Nikkei said citing Japanese authorities.
The guidelines entail creating the first international regulatory framework for decentralized virtual currency.
The objective of this inter-governmental organization is to have better surveillance over bitcoin and other virtual currencies and include identity verification for users who open “virtual wallets.”
It also examines control mechanisms for transactions that could have links to terrorist organizations like the Islamic State, authorities said.
Japan is at the forefront for bitcoin regulation after approving a law in March 2014 to classify this cryptocurrency -form of payment that has encrypted back-up data of its material value- as a commodity and not a currency.
Soon after, U.S. International Revenue System announced that, for tax purposes, bitcoin and other virtual currencies will considered as intangible property and not a currency, making them taxable.
These measures were designed after the Mt.Gox, bitcoin exchange bureau located in Japan, went bankrupt, affecting around 100,000 clients.
FATF is an inter-governmental organization established in 1989 by a group of seven countries, popularly known as G7, to control money laundering.

Is there any fiat-pegged and decentralized coin scheme that actually works? Is such a thing at all possible? It would be very useful for the transition from fiat to other cryptocurrencies, in most real world business the wild fluctuations of fiat/crypto price are a high impediment to adoption.

This seems an important development, along with the 800 atm in Romania of just a few days ago BitoEx has a new solution for buying Bitcoin in Taiwan that will be familiar to Taiwanese Bitcoin users. “Things have changed in the last 6 months,” according to Jason Gatewood. Gatewood has filmed a descriptive Youtube video that details the buy process now available to 20+ million Taiwanese. Some countries and continents, such as Africa, are getting Bitcoin access through existing mobile payments services. In other parts of the world, the e-banking community is ready to interact with companies that provide services for Bitcoin companies in Bitcoin purchase agreements, allowing banks to serve as Bitcoin gateways. https://www.cryptocoinsnews.com/taiwanese-can-now-buy-bitcoin-2980-family-mart-convenience-stores-bitoex/ |

Sorry if it was already discussed but I can't find it. Is there any merits in the following paper? "A Bitcoin system with no mining and no history transactions: Build a compact Bitcoin system" http://arxiv.org/abs/1404.4275 |

La prima Multipool per una criptomoneta Proof-of-Stake ha concluso la fase beta: il futuro di Bitcoin è NxtUn team di appassionati ha lavorato negli ultimi mesi su quello che è stato definito come il Bitcoin 2.0: Nxt. NXT è una evoluzione dei fondamenti tecnologici alla base del Bitcoin ed è basato su un nuovo codice sorgente invece di essere un semplice fork. NXT è una delle prime implementazioni di quelle tecnologie che si possono definire “criptomonete di seconda generazione”, come per esempio il sistema di messaggistica distribuito, lo scambio p2p, i multigateway e i mercati decentralizzati. NXT è anche in grado di risolvere quello che forse è il più grande difetto Bitcoin, grazie alla capacità di confermare le transazioni quasi istantaneamente. Nxt è semplicemente più veloce e più economico di Bitcoin e offre più funzionalità rispetto a Bitcoin e a tutti i suoi cloni messi insieme. I vantaggi di essere tra gli early adopters?Gli investitori sono in fila per entrare a far parte di NXT il più presto possibile. E' successo lo stesso con Bitcoin: chi è in grado di capire l'innovazione tecnologica alla base del prodotto ha maggiori probabilità di essere notevolmente ricompensato per il suo investimento. Far parte dell'ecosistema di NXT (le tante caratteristiche, come quelle citate sopra, lo rendono più di una semplice moneta!) è un investimento ancora molto abbordabile per i piccoli investitori, non c'è bisogno dell'ammontare di capitale necessario per il tipico investimento sul Bitcoin, mentre il ritorno è potenzialmente assai maggiore. Perché Nxt?NXT è stata la prima criptomoneta 100% Proof-of-Stake, il che significa che tutte le monete presenti sul mercato esistono da quando la moneta è stata creata. Questo è differente dal metodo del Bitcoin, che utilizza il mining per creare nuove monete. In realtà ci sono altre monete “cloni” di Bitcoin , che utilizzano il “Proof-of-Stake”. Ma il problema con Blackcoin, Coin2, Communitycoin, Faircoin, Peercoin, Premine o Whitecoin è che sono prive di funzionalità speciali e i tempi delle transazioni sono ancora lenti. A volta la scarsità è sufficiente per far salire il prezzo, ma non può creare la domanda. La domanda è legata all'utilità dell'oggetto, non solo alla sua scarsità. E non dipende nemmeno dal numero di venditori che accettano una criptomoneta. Per esempio Earthcoin è crollata anche se tantissimi negozi la accettavano. Blackcoin, per esempio, ha una utilità solo di poco superiore al Bitcoin (tempi di conferma più brevi). E ha un piccolo gruppo di pumpers&dumpers, che sono disposti a minare Blackcoin, ma solo per una ragione: rivendere tutto non appena arriva a 50 mila Satoshi. Nxt, invece, è all'avanguardia nell'offrire una serie di innovazioni tecnologiche nel campo delle criptomonete e la richiesta queste funzionalità sarà sicuramente elevata in futuro. Nessuno può sapere quando Blackcoin ripeterà il crollo dell'Auroracoin, di Mazacoin, di Megacoin, di Mintcoin, di Pandacoins o Quarkcoin. Ma prima o poi succederà. Con Nxt ci saranno solo rialzi in futuro. Grandi rialzi. Perché? Immaginate quando le Startup potranno finanziarsi tramite crowdfunding o sottoscrizioni pubbliche (IPO) direttamente sull'asset exchange di Nxt. E poi diventare aziende di successo con milioni di clienti. Non sarà solo una piccola bolla come le azioni Maidsafe di Mastercoin. L'asset exchange di NXT sarà la soluzione più veloce di tutte, in pratica - l'unico e migliore mercato decentralizzato con multigateway. NXT è completamente nuovo, creato da zero, più veloce ed economico di Bitcoin e di tutti i suoi cloni! Come ottenere NXT – Il mining sulla MultipoolIl prezzo di un singolo NXT è ancora piuttosto volatile, simile a quel che succede con Bitcoin. La Multipool è stata creata per contribuire a mitigare queste fluttuazioni giornaliere e aiutare a stabilizzare e aumentare il prezzo di NXT. Dopo aver funzionato in modalità beta limitata per oltre 30 giorni, Hashrate è riuscita a pagare ai suoi minatori un ammontare di NXT che equivale a oltre 15 Bitcoin. L'effetto a lungo termine di una infusione continua di BTC nell'ecosistema NXT favorirà il rialzo del prezzo della moneta. I minatori che considerano la propria attrezzatura come un investimento difficilmente possono trovare una scelta migliore della Multipool Hashrate - avranno un payout più alto in monete NXT rispetto a qualsiasi altra Multipool che paga in BTC. Per coloro che non sono minatori: chi investe sulle innovazioni tecnologiche deve prendere in considerazione di aggiungere NXT al suo portafogli. I prezzi attualmente bassi in combinazione con le caratteristiche tecnologiche innovative che costituiscono l'ecosistema NXT ne fanno uno delle poche criptomonete con un futuro brillante. NXT è disponibile per l'acquisto su quasi tutti i principali exchange, come BTER o Cryptsy.

Salve, non mi intendo di mining ma sono interessato a Nxt e voglio segnalarvi queste due nuove pool attive da una settimana: nxtp00l.org hashrate.org Si tratta di pool create apposta per "minare" Nxt che è una criptopiattaforma Proof-of-Stake, ovviamente essendo una PoS non si può veramente "minare", quello che viene fatto è minare tutte le coin PoW più redditizie che sono subito rivendute in cambio di Nxt. Poi i Nxt sono redistribuiti ai minatori. Questo spinge in basso il prezzo delle altre coin, mentre Nxt viene pompato. Sono attive da pochi giorni ma dalle prime testimonianze i rendimenti sembrano in linea con le pool tradizionali. Faccio notare che non è possibile nessuna rappresaglia simile contro una PoS, quindi, se questa idea dovesse avere successo, tutte le nuove coin basate su PoW sarebbero uccise nella culla... http://www.reddit.com/r/NXT/comments/214aqv/two_nxt_shascrypt_pools_exist_please_assist_by/https://nextcoin.org/index.php/topic,4399.0.html |

La casa è appena abitabile ma, per metterla a posto bene, dopo l'acquisto bisogna spendere altrettanto. Magari c'è qualche early adopter interessato...
