Payvo Wallet - Overview of the Upcoming Alpha Version


What Is Payvo Wallet?
Payvo Wallet is a desktop-based multi-asset cryptocurrency wallet designed for Windows, MacOS, and Linux. While many wallets already exist on the market, Payvo is unique in that it is completely open-source, runs on the open-source Payvo SDK for multi-asset integration, and features a wide range of customizations that let you truly personalize your wallet experience.

#A Truly Open Wallet
The Payvo Wallet is fully open-source and will be available on GitHub. The Payvo SDK which powers the multi-asset nature of Payvo is also completely open-source and available on GitHub. We believe that the best way to push the industry forward is to build fully open-source and decentralized systems with no compromises.

By utilizing the Payvo SDK, we can integrate a wide range of different cryptoassets and tokens which will be seamlessly integrated with the entire Payvo suite of products. To find out how you can get your project added to the Payvo SDK, make sure to read our documentation .

Interview: Erik Zhang discusses OneGate and Galaxz


As a founder and core developer of Neo, Erik Zhang is responsible for much of the project's early codebase, architecture, and strategic technical direction. With the launch of the Neo N3 MainNet in August, the blockchain-veteran is now able to allocate some time to work on other new projects within the ecosystem.

NNT caught up with Zhang to gather his thoughts on the Neo N3 release, and learn a few more details about his new projects.

NNT: Neo N3 is finally out the door. That has to feel really good, considering how long and how hard you've been working on it. What aspects of the release are you most proud of?

Erik Zhang: Neo N3 was initially designed to serve large-scale commercial applications and the real economy. To meet the demand for large-scale commercial applications, a blockchain should by all means make three major breakthroughs:

First of all, reliability, which is reflected in the irreversibility of transactions in a blockchain system. Once a transaction is committed to the blockchain, it can never be reversed or undone. Typical transaction reversals, such as double spending, sometimes occur in traditional PoW or PoS mechanisms. However, thanks to its unique dBFT2.0 consensus mechanism, Neo N3 has "one block finality" and only one block confirmation (15 seconds) is required to ensure irreversibility of the transaction. Since the transactions in key financial applications should never be reversed at will, this feature is critically important for large-scale commercial applications.

The second is performance. High performance is often required in large-scale commercial applications, which is difficult for existing blockchains to achieve. For the existing blockchain systems, transaction blocking and huge fees may come with growing business volume, hindering the process of implementing large-scale commercial applications seriously.

Fully aware of such significance, we designed Neo N3 with a strong focus on performance and scalability. According to the latest experimental data, the underlying business processing capabilities of Neo N3 can now reach 30,000 TPS, which is quite enough to carry large-scale commercial applications after being extended by Layer2.

Finally, there is big data storage. It is absolutely difficult to store the huge amount of data generated by large-scale commercial applications on the blockchain. Thus was born the idea of NeoFS, a distributed storage system designed to store massive amounts of data. NeoFS is underpinned by the N3 infrastructure, which is capable of providing N3 with nearly unlimited cloud storage space.

And for the real economy, we must provide a mechanism that can bridge the real world and the blockchain world. N3 has native Oracles that allow smart contracts to access the Internet at runtime and get information from the real world.

Beyond what we've mentioned above, N3 has many other new features in other areas, such as exception handling for smart contracts, native contracts, a new governance model and so on. I also developed a new C# compiler that compiles the source code of smart contracts into deterministic bytecode, which is very useful for verifying the source code of contracts.

NNT: You're now working on OneGate, a Neo wallet, and Galaxz, a Neo-based blockchain game. I think this surprised a few people, but we were really glad to see you building products on the chain you created. Has this always been a goal for you – to not only build Neo, but build on Neo? Or are these projects an exercise in experiencing your creation from the application development perspective?

Zhang: Before I continue, let me tell you up front that OneGate is more than just a wallet. It was designed to be a gateway to the blockchain world for normal Internet users.

Furthermore, Galaxz is more than just a blockchain game. More precisely, it is a sci-fi space adventure MMORPG, about which ideas were born early on, including a huge worldview of subtle complexity, improbable plot twists, and many of my own philosophical thoughts.

And of course, Galaxz – or rather, all the projects I build – will have a deep integration with Neo.

NNT: What can you tell us about OneGate? What are the motivations for starting that project, and what is it bringing to the table that was missing from the Neo ecosystem?

Zhang: As I mentioned before, OneGate is a portal specifically designed for normal internet users to enter the blockchain world. Designed for users who have a good understanding of blockchain knowledge, the existing blockchain wallets and clients tend to provide users with DeFi and NFT features, and promote blockchain related news. As for me, I'd like to break the boundaries between blockchain and the internet, to provide users with all the features they need. Users will then be able to use blockchain just like they use the internet.

Neo aims to be the next generation of the Internet.

NNT: Galaxz is a sci-fi space adventure game, and your love of sci-fi culture such as Star Wars is well known. You mentioned to someone on Twitter that you have been waiting 16 years to build Galaxz. Can you describe to us the game concept and explain why now is the right time to bring it to life?

Zhang: When I was in high school, I got very frustrated with the boring missions and poor storylines of the MMOs of the time. Therefore, I started to come up with the idea to build a sandbox space adventure game based on the laws of physics and have already designed some very innovative gameplay.

After graduating from college, I started working on information security, an industry that has little to do with gaming. So the imagination about Galaxz has never been a reality before.

Then I started working on Neo, during which the idea of developing Galaxz was rekindled – this time on Neo chain. Soon I bought the domain name for 10 BTC. Preparations proceeded night and day, until I found It nearly impossible to work on Galaxz and N3 development at the same time. So the plans for Galaxz were laid aside temporarily.

Now that the N3 MainNet was launched, there's nothing to stop me from continuing to develop Galaxz!

NNT: What platforms will Galaxz be available on? Mobile app, browser, desktop client, etc?

Zhang: There will be three different types of clients available for Galaxz.

Full-featured Client: The full-featured client will run on consoles such as PC, PS or Xbox, showing gorgeous battle scenes and cosmic views with their powerful processors and graphics cards. With a full-featured client, you can experience all the features of Galaxz.

Mobile Client: The mobile client requires a game app installed on the phone, through which users can experience almost all of the features, such as planet construction, manufacturing, technology upgrade and so on.

Web Client: With a web client, users can access some of the game features via their browser. For example, designing spaceships, accessing the marketplace, chatting, sending and receiving emails, etc.

NNT: A lot of blockchain games these days are cross chain, and Neo does have Poly Network integration. Will Galaxz only be on Neo, or down the line do you intend to expand the universe into other chains?

Zhang: The core logic of Galaxz will not be on-chain. However, tokens will be issued on Neo with the NEP-17 standard, while props will be issued with the NEP-11 standard as NFTs.

Through PolyNetwork, indeed, anyone can send their tokens and NFTs to other blockchains to build a larger universe.

As to Neo itself, tokens and props of Galaxz can also be used universally in all other Neo-based blockchain games.

NNT: The stage is really set for Neo now. N3 is live, the migration is well underway, new dApps are coming to the platform, the governance system is up and running – What is next, and what are your personal goals for the project over say, the next five years?

Zhang: For me, N3 is complete enough to be called an "all-in-one" blockchain system. In the future, I will certainly continue its optimization and improvement, and may also launch N4 or N5. But for now, I prefer to bring more applications to Neo – not just blockchain applications, but Internet applications as well.

In the next 5 years, I'll mainly focus on N3 and Galaxz.

El Salvador mines first bitcoins from volcanic energy


El Salvador officially mined its first Bitcoins using a volcano. At the same time, geothermal energy now accounts for about 22% of the country's market.
Previously presented as a concept, the project of mining cryptocurrency using volcanic energy turned out to be a surprisingly viable idea. So much so that today the President of Salvador Nayib Bukele shared on Twitter a photo from the monitor showing the number of cryptocurrencies mined in this way. By that time, it was 0.01083 BTC, of which 0.0048 BTC is already awaiting withdrawal.

The country not only actively uses geothermal energy personally, but is also one of its largest producers in the world. It is generated by 20 volcanoes located in the region, which scientists have described as "potentially active". Given their number, this use of natural power is hardly surprising, although Bukele's resourcefulness still amazes many miners. In addition, such energy is classified as environmentally friendly, so the "green miners" will also have no claims against the country.

On September 28, the president shared a video on his Twitter account, which showed the delivery of equipment in the form of ASIC miners, as well as the process of installing and configuring them. The local energy company LaGeo is directly involved in the project, thanks to whose specialists the country's authorities were able to quickly implement the idea.

According to Bukele, the equipment is still in test mode and they are testing it, but it has already given the first results. Of course, it was not without spiteful critics, because in the comments and retweets people shared the opinion that the president should use a period of at least three hours of equipment operation for reports, while others even joked about the level of "home mining".

Recall that the law on the legalization of Bitcoin in El Salvador entered into force on September 7, and by the 27th of the same month, according to Bukele, 2.1 million residents were using the state-owned Chivo cryptocurrency.

Compound Founder Says $80M Bug Presents ‘Moral Dilemma’ for DeFi Users


While Robert Leshner seemed to briefly threaten users with the IRS, the reality is that he – and the rest of the Compound Labs community – are now relying on the goodwill of users.

If a decentralized finance (DeFi) protocol accidentally gave you millions of dollars in tokens, are you obligated to give it back?

In an interview with CoinDesk following an $80 million exploit, Compound Labs founder Robert Leshner is arguing users should do just that.

On Wednesday night, a bug in money market Compound's code led to an erroneous disbursement of COMP tokens intended for long-term liquidity mining rewards.

The Compound Twitter handle acknowledged the bug shortly after, saying that no user funds were at risk. The bug only applied to Compound's Comptroller Contract, which is responsible for distributing liquidity mining rewards earned over time.

Nearly the entirety of the Comptroller Contract has now been drained, with 280,000 COMP distributed to users incorrectly, according to Leshner.

Despite the eye-popping sums lost to the bug, however, the community is now captivated by a debate as to what users should be obligated to do with their funds.

"This has been, without a doubt, the worst day in the history of the Compound protocol," Leshner told CoinDesk.

He went on:
"What makes it way worse is that I and most folks are completely powerless to do anything besides sit back and watch this moral dilemma play out."
IRS threats
In a Tweet on Thursday night, Leshner seemed to warn recipients of the erroneous tokens that there could be real-world consequences for keeping them – namely, that the U.S. Internal Revenue Service (IRS) might want to hear about it:

Some members of the DeFi community interpreted the comments to mean that Compound Labs was planning to report recipients to relevant tax authorities. Leshner apologized for the tweet shortly after.

Threats of "doxxing" have proven to be effective in dealing with exploits in the past – last month, a non-fungible token (NFT) team memorably threatened to call in the FBI and ordered soup to a hacker's address. The hacker relented, returning stolen funds.

However, in this instance even if an organization wished to pursue claimants, in practicality it may be an empty threat.

Compound Labs is a real-world entity that is working on the protocol, but there's no clear basis for it to pursue legal action – the structure of the decentralized autonomous organization (DAO) is such that it is now just another member of the community, according to a Compound Labs representative.

The representative also said the Compound interface is hosted on distributed file storage protocol InterPlanetary File System (IPFS) and there's no reportable information about users collected in any way.

However, due to the nature of the bug, many of the recipients of the tokens are not sophisticated hackers – they just happened to hit the jackpot.

Their operational security, or opsec, isn't hacker-grade. Some addresses that claimed large sums of the tokens have interacted with centralized exchanges where their real-world information is stored, and the claims could have an impact on their taxes.

Claiming the funds required no knowledge of the bug, and some users might not have been aware there was an exploit underway – they may have received millions while intending to harvest much smaller sums as rewards.

Leshner said the DeFi community has rallied around the protocol in an effort to find solutions. Yearn.Finance and MakerDAO representatives have been active in community channels in finding short- and long-term solutions.

However, Compound has an "extremely rigid" and slow governance process by design – architecture intended to make the protocol more resilient is now acting as a barrier to a fix. It will take another five days before the community can approve any updates to the contract code.

Technical solutions to the initial bug aside, however, the protocol now faces an even bigger problem: trying to convince users who received tokens to return them to the community.

"In my opinion, this is a bank error in a couple people's favor," said Leshner.
