EOS Hot Sauce is a weekly digest of all the hottest topics from around the EOSIO ecosystem. The space is evolving so rapidly it can be hard to keep up! We keep on top of it so you don’t have to.

EOS Celebrates Second Birthday

It’s been two years since the launch of the EOS Mainnet – and what a wild ride it’s been!

The pace of innovation in this space has been mind boggling. So much so, that it feels like a blur and is easy to forget what we’ve accomplished as a community in such a short time.

So to celebrate, let’s take a short pause to look back and appreciate how far we’ve come with a week-by-week look at everything that happened on EOS from June 2019 to May 2020.  

          June 2019

Technical note regarding EOS’ actual birth date: June 1st is the 2nd anniversary of the EOSIO 1.0 release. The first block on the EOS Mainnet was produced by the Appointed Block Producer (APB) on June 8, 2018, at 8:08AM 8.888 seconds. The “go vote” was obtained on June 9, 2018, at 01:00 UTC. The Mainnet was launched on June 10, 2018, at 13:00 UTC and the chain hit 15% voting (it’s own metric for official activation) on June 14th, 2018.

Operating EOSIO with Matthew Darwin: New Wallet API

New wallet API

Block.one recently released EOSIO 2.0.6, which contains a new feature: the get_accounts_by_authorizers API. We’re going to call this the “wallet API.” Why is this newsworthy? Let’s look at what functions EOSIO wallets need and the series of events that landed us here.

How do wallets work?

Wallets rely on EOSIO nodes provided by block producers, exchanges, wallet providers, and other relevant stakeholders.  “Find an account,” “get the token balance,” or “perform a transaction” all need an EOSIO node to work.

When you use a wallet for the first time you need to provide it your key in order to get your account name. This article focuses on how that first step actually works.

Ancient times

When the EOS Mainnet was first launched in June 2018 using EOSIO 1.0, it had a feature called “history plugin” (which still exists today but is deprecated). EOSIO history accumulates all the millions of transaction that happen on chain and makes it available for querying. This includes the information about how to find an account based on a key.

Initially many block producers enabled history features and made the information publicly available for wallets to use. But because EOSIO can handle a lot of transactions, the history size got excessively big, became unmanageable, and prohibitively expensive to operate. It’s just not a scalable solution.

The last 18 months

Several alternatives have emerged to this history plugin that wallets use today. However, these history solutions are not integrated into EOSIO. The cost of running this additional infrastructure means the number of available nodes to query is limited.

Wallets need a standard widely deployed solution so they’re not locked into any specific node API for this fundamental query.

Wallet API development

Starting in February 2020, there was a discussion in the EOS Mainnet BP telegram channel about the functionality that wallets need to look up accounts from a key. A new feature in EOSIO was needed. In March, Block.one made the first version of this proposed feature available for review. There were several rounds of comments from API providers as well as wallet developers, which resulted in many revisions.

In April, EOS Nation deployed this new API on the Jungle test network to make it available for testing. As changes were made to the API, the nodes on Jungle test network were updated.  

The new wallet API was included in a formal EOSIO release on June 3. Nodes need to upgrade to version 2.0.6 and enable a configuration option to make the wallet API available for use. We’ve also added a wallet API check to the EOS Nation Validator.

Going Forward

The advent of this new wallet API does not render the various history solutions obsolete as it only covers a small set of functionalities that many wallets use. However, it does provide a low-cost set of features whereby more providers can offer the solution, which in turn leads to further decentralization and redundancy options for the users. Feature rich wallets will continue relying on robust history solutions.

Transitioning to a state where wallet providers take advantage of this new feature will be a gradual process taking place over several months. During this period, EOS Nation will promote this API to other block producers and ask them to consider enabling it as well as promoting it with wallet developers and ask them to add support for it. 

We look forward to the continuing decentralization of the EOS mainnet!

Block.one has rotated their votes for the first time and are now voting for a new list of 10 block producers, which includes EOS Nation! Thank you Block.one for recognizing the contributions done by the founders, Ambassadors, employees and community of EOS Nation.

Block.one’s revolutionary new social media platform, Voice, will be available worldwide on July 4th. Voice CEO, Salah Zalatimo, dropped the news casually in his latest post on Voice, which is currently only available to residents of the United States:

“On July 4, we will set Voice free on the world. Our journey begins there.”

He later followed up on Twitter to clarify the details:

The official Voice Twitter account also chimed in with an interesting tidbit:

Shared in its entirety below, Salah’s post discusses Voice’s innovative approach to content moderation, which focuses on empowering the real users of the platform.

The topic of censorship on major social media platforms has never been more relevant. Facebook, Twitter and YouTube have all been recently criticized for higher and higher levels of censorship applied unevenly across users and subject matter. Voice is an attempt at building a better social media platform from the ground up. By scrolling through Salah’s Twitter feed, it’s clear the the Voice CEO has big hopes and dream for the platform. Here are some of our favorite recent tweets from Salah:

The team at WAX announced the WAX Advisory Council this week, consisting of high profile representatives of the tech, video gaming and entertainment industry. 

The role of the Council Members goes two ways, to “offer recommendations and guidance to the WAX Team that’s relevant to their area of expertise” and, as an ambassador, to communicate the potential of blockchain solutions to their companies.

The first members will be announced over the coming weeks via Twitter, starting on Tuesday, June 9. 

The exciting news has created a pretty big buzz in the WAX community and in the trading markets! Congratulations to all WAX holders! 

The realistic approach to Blockchain Technology of the WAX team is often presented in the WAX On video series and also in the forthcoming design principles of all their products.

Many members of the team have a profound experience with traditional businesses, survived the Dotcom bubble, and finally with WAX, created a framework to onboard users and businesses onto the blockchain. The new WAX Advisory Council will serve an essential part of this mission, and we’re excited to learn more.

Meanwhile, the trading activity of Garbage Pail Kids NFTs on the secondary markets is still going strong and we put together a tutorial video for the Simple Market, where you can trade GPK cards along with other WAX based NFTs.

The GPK Market, a marketplace exclusively for the Garbage Pail Kids, also just added the auction feature to their platform and the bids are running hot as expected. 

If you’re completely new to WAX and want to quickly catch up, the WAX School might be a good start. They just added a new video about the GPKs and trading NFTs on WAX.

Ultra currently consists of over 60 employees, and while preparing for the launch of their gaming ecosystem, they’ll continue hiring high-quality talent until they’ve reached a total of 100 team members. To achieve this goal Mathilde Kurzawa joined Ultra as a Talent Acquisition Manager. 

In the most recent Ultra Community Update you can find a pretty cool game style map, showing how diverse and decentralized the Ultra Workforce is distributed across the globe.

The next step in the development process for Ultra is the launch of the testnet. And since it will be running a unique version of EOSIO with a couple of yet unannounced core features, there’s a lot of testing involved, so that stable performance and a high level of security is ensured when Ultra goes public.

Another developer-oriented milestone was reached in regards to the Ultra SDK, a toolkit to streamline the workflow for game developers. The Ultra SDK successfully reached “Steam feature parity,” meaning that all Steam features are integrated and game developers can easily port their games from Steam over to Ultra. Once on Ultra, they can benefit from all the Ultra blockchain features, which you can revisit in this short yet impressive video.

We encourage all gamers and game developers to visit the Ultra website and sign up before the platform launches. And join the Ultra Announcements Telegram channel to stay up to date.

EOS Argentina, EOS Costa Rica and EOS Venezuela formed the LatamLink alliance on May 15 and deployed an EOSIO testnet for the LAC-Chain ecosystem, an alliance to promote the use of blockchain in Latin America and the Caribbean.

This testnet will be used to showcase to Latin American developers the many attractive benefits of building on an EOSIO blockchain protocol. The LatamLink roadmap highlights some interesting upcoming features of the network, such as the LACChain POA System Contracts and a smart contract based rotation of core nodes.

LAC-Chain was launched back in 2018 by the laboratory division of the largest source of development financing for Latin America and the Caribbean, Inter-American Development Bank.

Congratulations to EOS ArgentinaEOS Costa Rica and EOS Venezuela for this great initiative and thank you for actively contributing to the adoption of EOSIO in Latin America!

The Anchor wallet has gained the ability to import EOS accounts and private keys directly from Scatter without having to expose your keys.

This is one of the features we’ve been most looking forward to, and Yves La Rose even asked for it on the latest episode of Everything EOS last week!

Well, Greymass listened and Greymass delivered! The pre-release version of Anchor 1.0.4 came out this week and includes an experimental feature: Scatter Backup Import!  🎉

Important Note: Scatter Backup Import is an experimental feature, which means it requires further testing before being officially released. Make sure to read the release notes before trying it out.

TurnCoat Galaxies is a new PVP/real time strategy game that requires cooperation between players while leaving open the possibilities of betrayal, especially near the end of the season with leaderboard prizes up for grabs. The game is currently in open beta (no prizes yet) and has many planned features to come, including being on many EOSIO chains at once and enabling players to move from one network to the next.

TurnCoat Galaxies currently lives on the Telos testnet, and making an account is free and easy. Join us in the game, follow TurnCoat Galaxies on Twitter and jump into the Telegram channel to chat it up with your fellow game players. See you on the game board!

So much is happening over at Effect.ai that the team had enough news to host two AMAs in a short time. As in the previous AMA, which we summarized in EOS Hot Sauce #55, they teased an upcoming exchange listing, the team now revealed a USDT/EFX trading pair on the Bidesk exchange.

Before getting into the community questions, the team also shared other developments, such as additional languages for their translation services and details about the upcoming Effect DAO. 

An essential element of the Effect DAO is the NFX token, which can be earned by staking EFX on the Effect.ai Dashboard. In case you’re new to this model, check out introductions for the NFX Token, the Effect Staking Protocol, or just follow the steps in the EFX staking tutorial.

One of our highlights of the AMA was the great answer by chief engineer Lawrence Verspeek to the question “is the Effect.ai team still happy with the EOS Blockchain?” He confirmed that they are indeed very happy and highlighted the overall professionalism and flexibility of EOS technology and development tools, making it the perfect environment for their ambitious project. Listen to his full answer for yourself – we’ve included a timestamp to the question in the link. 

The date of the Effect.ai AMA fell on a special occasion, the Birthday of Effect.ai CEO, Chris Dawe. We’d like to take this opportunity wish him all the best.

With a brand-new Staking Pool, the Equilibrium Framework added another important component to their web portal, allowing users to earn up to 11% APY for staking EOS, EOSDT, and NUT.

It comes with the usual intuitive interface and a calculator to predict potential earnings. All staked assets are safely stored in the Equilibrium Smart Contract, which just recently was further secured, and can be withdrawn at all times.

The interest rate that you can get for your staked tokens varies, depending on how many tokens are already staked to the pool. You’ll find more details and some walkthrough examples in the announcement article. Definitely worth checking out, even if you’re just curious about how advanced DeFi on EOSIO is already.

In a newly released overview, the dfuse team summarized the unique features that EOSIO has to offer to game developers and showcased some gaming related products and services that are already using their product. Since open sourcing their code for EOSIO, they’ve also created an API service for Ethereum, becoming yet another example of our mantra: the future is multi-chain.

As a new member of the Blockchain Gaming Alliance, dfuse certainly has a lot to offer, so that game developers can more focus on their product, instead of worrying about the blockchain plumbing.

We highly recommend interested developers to subscribe to the dfuse YouTube channel and check out a recent webinar on how to install and use the open-sourced “dfuse for EOSIO”.

To demonstrate the endless opportunities that can be achieved by combining DAPP Network services, the LiquidApps team took a closer look at Sharding. This horizontal scaling technology is currently explored by a variety of other blockchain protocols, but with the use of multiple instances of LiquidChains, it’s already possible. 

The article is underlining yet another example of how EOSIO can be integrated as a scaling solution for other blockchain protocols and serves as an open invitation for the wider developer community.

Using LiquidApps is not just efficient when it comes to computing resources, it’s also allowing dev teams to operate on a smaller budget. This superior cost-efficiency might even increase with Chintai’s new DAPP Token Leasing Market, which is scheduled for release in mid-June. 

In a Pre-Launch Update, the Chintai team gave some detailed insights into the value proposition of a leasing market for DAPP tokens, while also announcing their very own DSP.

Major takeaways of the article are:

  • The “Pool market” generates CDAPP, which can be redeemed at all times
  • Price changes for borrowers are based on a Bancor style curve
  • Lenders can earn double rewards when they also stake to the Chintai DSP 
  • Chintai DAPP leasing market could be used cross-chain

We’re very happy to see the Chintai team getting involved in the DAPP Network and giving DAPP Network users more options to choose from. 

Chintai will also be representing the EOSIO community as a platinum sponsor at the Singapore Blockchain Week Virtual Summit 2020.

Check out the latest LiquidApps round table discussion, where Zack Gall sat down to chat with LiquidApps CEO Beni Hakak and Dudu Azaraf, Marketing and Data at LiquidApps to cover these topics.

Both Upland and Wombat are celebrating some special anniversaries in the coming week. Check out their schedule to join the party.

The Coding for Change Online Hackathon has just ended.

Hosted by Block.one, it was announced on April 24th and ran for the whole month of May. Plenty of creators and developers signed up to compete in solving the following challenge: “Apply blockchain technology to address the problems and/or expected societal changes related to the COVID-19 pandemic.”

While we’re waiting for the winners to be announced on June 12th, we want to introduce you to a couple of teams that made their pitch public.

  • The Crypto Bartender

A Bartender is usually getting in touch with a lot of people, and therefore in times of an epidemic, there’s a certain risk attached. The Crypto Bartender makes it easy to get an order, get a refill, and pay for your drinks while still maintaining social distancing. It accepts EOS, EOS-based tokens, and works with QR-Codes. The inventor even created a token of his own for his customers to participate in promotions, while the smart contract automatically distributes profits to the bar owners.


  • Piña

Piña, another EOSIO Solution for the hospitality businesses, is a point of sale system with lots of social features, so that customers, staff, managers and owners can interact while keeping their distance. It comes with a Smart Wallet and an option to create promotional activities. Customers can browse, order, and rate businesses, while the managers of a business can organize working shifts and inventory. All that comes with a simple and fun interface, running on the EOS blockchain and the DAPP Network.

  • Lifebank

The Lifebank project put the difficult situations that blood banks currently are facing on our radar and also presented a solution. Due to uncertainties caused by the virus, blood donations in New York dropped 50%, and even 80% in Argentina.  Meanwhile, small businesses are also struggling.

And this is where Lifebank comes in, as it helps local communities to create a virtuous cycle of value exchange, by connecting blood donation centers, blood donors and local businesses via the Lifebank dApp. Lifebank was developed by EOS Costa Rica, who’ve now made it to the EOS Hot Sauce for the 4th time in a row with a variety of initiatives.

Some very interesting projects already. What’s your guess? Will any of the above teams win the first prize of $100,000 USD?

Sign up is open for the first Loop tokens to be airgrabbed by participating accounts.

We introduced you to Loop, a dApp brought to you by the creators of Trybe, in EOS Hot Sauce #53.

If you want to boost the number of tokens dropped in your account, you can fill in this short survey, giving some input so that the dApp can be designed according to the needs of the end-users.

EOSX wants your feedback about your overall impression of the platform and which features you’d like to see.

Those who submit the form will be entered into a contest to win some EOS! The survey pops up in the bottom right corner of the page after 30 seconds. It doesn’t work on the Brave browser and requires disabling ad blockers if you have them.

EOS Detroit, PixEOS and Cypherglass got together to celebrate EOS’ 2nd birthday by putting up a fun contest for the community. Can you find the 6 hidden EOSIO project logos in this image? Contest submissions end on July 9th!

EOS Nation is a top Block Producer on the EOS public network. We earn inflation rewards based on the percentage of tokens staked towards us. Those rewards are reinvested into EOSIO community, tools, and infrastructure. Help grow the ecosystem by staking your vote to eosnationftw for BP or proxying to proxy4nation

Remember, we never accept compensation in exchange for featuring projects in the EOS Hot Sauce. That means if a project is included in the EOS Hot Sauce it’s because we believe that project brings value to the EOSIO ecosystem and we want our community to know about it!

Are you building an interesting project on EOSIO? We want to hear from you! Reach out to us on social media or email info@eosnation.io.
