Kosen Labs, founded by ex-DeepMind researchers, aims to bring the benefits of advanced AI to the world of web3

Today, we are excited to announce that Kosen Labs has closed a $5 million seed round led by Andreessen Horowitz with major participation from Framework Ventures and other strategic partners.

We are a team of ex-Google DeepMind AI researchers with extensive experience in designing and implementing cutting-edge solutions to machine learning and numerical optimization problems. The models we previously worked on have been used to defeat world champions in the game of Go, beat top professional teams in Starcraft, and optimize billions of dollars in revenue across various Google products.

Now, after spending years developing and deploying advanced AI techniques to optimise closed-source systems, we believe it is time for a change. The benefits of AI systems should be accessible to anyone, in an open and permissionless way. Blockchains such as Ethereum and the emerging web3 ecosystem of decentralized applications offer such a promise.

“The worlds of AI and web3 are beginning to intersect and create a whole design space that we’ve barely begun to explore,” said Ali Yahya, General Partner at Andreessen Horowitz. “Miljan and Peter, the founders of Kosen Labs, are two brilliant researchers at that intersection. They are applying cutting-edge machine learning techniques to solve problems in the world of web3, starting with the DeFi problem of active liquidity management in modern decentralized exchanges.”

The web3 ecosystem is still very much in its infancy when it comes to using machine learning and statistical optimisation approaches, which is why we strongly believe that deploying these techniques can act as a big value multiplier for the whole space.

“Blockchains’ open source data and code are a panacea for building AI driven financial applications,” said Vance Spencer, co-founder at Framework Ventures. “The most impressive displays of AI — in our lifetimes — are likely to occur on-chain. Kosen Labs is a place where the brightest minds in AI can come and push the boundaries of what is possible at the intersection of finance and AI. We are beyond excited to back them.”

The mission of Kosen Labs is to bring the benefits of advanced AI to the decentralised economy.

As the first step on this mission, Kosen Labs will be focusing on delivering the best-in-class solution for active liquidity provision (LP) on the next generation automated market makers (AMMs), such as Uniswap v3 and Sushiswap Trident.

Introducing Espresso Systems

Introducing Espresso Systems

High costs and limited privacy functionality are pain points for Web3 users today and represent major barriers for the next waves of adoption and innovation. Soaring fees render many of today’s most popular decentralized applications inaccessible for large numbers of would-be consumers. Similarly, the fully transparent nature of most blockchain systems leave their applications unsuitable for any users that harbor sensitivities around their data. At Espresso Systems, we are building the scaling and privacy solutions that will unlock new possibilities for Web3 applications and usher in the next generation of users.

Espresso Systems is developing Espresso: a layer 1 blockchain system that combines proof-of-stake consensus and a ZK-Rollup mechanism to achieve high throughput and low fees. Espresso has also developed Configurable Asset Privacy for Ethereum (CAPE), an application that can run on any EVM blockchain (and will eventually run on Espresso natively). CAPE enables asset creators to offer users customized privacy guarantees.

Read more below about the way we are thinking about both scaling and privacy and how we are building the systems that will transform the possibilities of Web3. You can check out our first release of CAPE which will soon be live as a demo on Ethereum’s Rinkeby testnet. We have also open sourced Jellyfish, our library for zero-knowledge proofs and other cryptographic tools. Find us on Twitter and in Discord.

Decentralized ZK-Rollups

Espresso’s approach to scaling throughput involves a careful integration of ZK-Rollup for the EVM with a decentralized proof-of-stake consensus protocol. A ZK-Rollup is an emerging scaling technique, typically implemented as a layer 2 on top of an existing consensus protocol. A server aggregates a large number of transactions into a single summary transaction and produces a succinct zero-knowledge proof (zk-SNARK) of their validity, which is subsequently sent to the consensus system. This rollup proof compresses both the amount of information and the computation that the consensus protocol needs to validate the transactions, thus increasing the throughput. Several rollup solutions are in development for Ethereum, however, there is a caveat of the existing design space: the data availability problem. Users need data in order to construct new transactions. While a zero-knowledge proof can convey the validity of a transaction block without revealing its raw data content, it does not guarantee the availability of the data which is needed to build future transactions. To address the issue, existing rollups either include the raw transaction data within the summary transaction sent to consensus, or use a centralized data availability committee to sign off that it has seen the data. Neither is satisfactory: the first has limited compression and thus limited scaling, while the second undermines decentralization.

What is needed is an approach that can maximize throughput while maintaining decentralized data availability. At Espresso Systems, we are developing a solution to this by tightly integrating the ZK-Rollup scaling mechanism with our proof-of-stake consensus protocol from the start. The fact that the Espresso ZK-Rollup is natively integrated with consensus—and does not need to treat it as a black box—is what will enable Espresso to avoid the trade-off of other designs which approach the rollup as a separate modular component agnostic to the underlying consensus protocol.

We will be sharing much more about our approach to scaling over the coming weeks. For updates, please stay tuned via our Twitter and our Discord channel.

Configurable Asset Privacy on Ethereum

CAPE (Configurable Asset Privacy for Ethereum) is a smart-contract application developed by Espresso Systems which enables digital asset creators to determine who can see what information about the activity in the tokens they mint.

Digital assets on CAPE, from stablecoins to NFTs, can be customized to balance transparency, a noted benefit of Web3 products, with privacy, wherever it is required by users. While CAPE transactions appear anonymous and indistinguishable to normal viewers, hiding even the type of asset being transacted, the creator of an asset can configure a viewing policy, which ensures that select parties can decrypt select information about transactions for that asset.

CAPE can be used to create new assets or to wrap assets that already exist on Ethereum, endowing them with privacy properties. Wrapping an ERC-20 with CAPE requires the specification of a wrapper type, which configures who can see what and who can maintain specific controls regarding the assets in question. Wrapping locks the asset in the ERC-20 contract and creates a corresponding CAPE asset of the specified type, while unwrapping burns the CAPE asset and releases the lock.

While CAPE can be used by anyone looking to create or wrap assets, the protocol was designed with stablecoin providers specifically in mind. Stablecoin providers today generally want to maintain avenues to be able to address fraud, theft, and dispute resolution, demanding that they retain insights into the ledger of activity for their assets as well as controls like freezing capabilities. Prior to CAPE, there were no solutions for these types of asset creators to offer privacy-enabled versions of their tokens to users while being able to meet needs around visibility and dispute resolution. With CAPE’s viewing and freezing policies, this is now possible. In addition to empowering asset creators with these abilities, CAPE empowers users to be aware of and to actively opt in and out of what data they are sharing and who has insights into and control over their transactions.

CAPE is open sourced here. While CAPE can be run on any EVM blockchain, we will be deploying it soon as a demo on the Ethereum Rinkeby testnet with ultimate plans to migrate the application to Espresso and enable interaction with Ethereum assets via a token bridge.

You can check out CAPE’s open source contracts here and documentation here.

What’s Next

To make all of this a reality, we are thrilled to share that Espresso Systems has raised $32mm in funding led by Greylock Partners and Electric Capital with participation from Sequoia Capital, Blockchain Capital, and Slow Ventures. Espresso Systems also includes major industry players as backers, including Polychain Capital, Alameda Research, Coinbase Ventures, Gemini Frontier Fund, Paxos, and Terraform Labs.

This funding will provide the resources necessary to grow the team researching, building, and implementing the infrastructure and products that will make Web3 ready for broad adoption. The funds will also go towards bringing these products to market through a range of channels: distribution of native end-user products, developer adoption, and partnerships with entrepreneurs, startups, and enterprises.

Over the next few weeks, we will be deploying CAPE on the Ethereum Rinkeby testnet and releasing a graphical user interface for the application. We will also be sharing more about our scaling solution.

Ankr partners with Optimism to provide a fast and reliable RPC service for users

Ankr partners with Optimism to provide a fast and reliable RPC service for users


Ankr, one of the industry’s fastest RPC providers and web3 developer toolsets, has announced that it will become a remote procedure call provider for Optimism.
Optimism is an open-source layer-2 scaling solution for Ethereum that focuses on speed and efficient transactions across the network. It has caught the eyes of many in recent months, including Ethereum co-founder Vitalik Buterin.
Ankr has assisted many industry leaders such as Solana and Avalanche by running their blockchains faster, allowing for better Web3 experiences across the globe.
This partnership will allow decentralized application (DApp) developers from all parts of the world access to Optimism’s public and premium RPCs. “We love what Optimism is building for the future of Ethereum. Ankr is happy to do our part to provide a fast and reliable RPC service for their users,” said Greg Gopman, chief marketing officer of Ankr.
Ankr also said that it will incentivize independent Optimism node operators to add their nodes to the load balancer in return for ANKR tokens.
Back in November 2021, Ankr Network co-founder and CEO Chandler Song wrote about multichain technology as a necessity for the future of decentralized finance (DeFi) products.
TrueFi launches on Optimism, expanding access to on-chain credit

TrueFi launches on Optimism, expanding access to on-chain credit

Unsecured lending protocol TrueFi has become the latest project to launch on Optimism, Ethereum’s popular layer-2 scaling solution, in a move that’s expected to boost demand from non-institutional lenders.
By launching on Optimism, TrueFi’s lender community will have access to a faster and cheaper user experience, as well as gain exposure to a wider pool of retail lenders. “TrueFi users can now lend, borrow and launch portfolios on Optimism to enjoy dramatically reduced transaction costs and network speeds,” Rafael Cosman, co-founder of TrustToken, told Cointelegraph in a written statement. He further explained:
“Since Optimism transactions are on average 77x cheaper than Ethereum, we expect greater adoption from non-institutional lenders, hopefully increasing global access to TrueFi’s financial opportunities.”
TrueFi was built by stablecoin operator TrustToken and shipped to institutional clients in November 2020. In February, TrustToken launched a new lending marketplace on TrueFi designed to give financial institutions the ability to design and launch their own financial products.


Optimism Goes Live With Airdrop

Optimism Goes Live With Airdrop


The Layer 2 scaling network launched its new token after much anticipation late Tuesday. As is standard practice in the crypto ecosystem, Optimism initially distributed OP via an airdrop to a select number of eligible addresses. Early Optimism users were rewarded, along with those who met other criteria such as having used bridges to move tokens off Ethereum mainnet or donated to Gitcoin within a set timeframe.
Early hints of today’s launch first surfaced when Bybit, MEXC, and other exchanges announced plans to open OP spot trading imminently. The Optimism team also surfaced on Twitter this afternoon to share a cryptic message with the community. “sup nerds,” it read.
OP is expected to play a vital role in the Layer 2 ecosystem as its holders will essentially have the power to decide how the network’s future will look. Notably, in a move not seen in other prior Ethereum airdrops, Optimism is also planning to issue non-transferable “soulbound” tokens to members of the Optimism Collective. The team has dubbed OP recipients as members of the “Token House,” while the soulbound tokens will go to members of the forthcoming “Citizens’ House.” Together, these two factions will form a bicameral system to govern Optimism’s future.
Polygon Announces ‘Polygon Fellowship’

Polygon Announces ‘Polygon Fellowship’

Polygon is pleased to announce the launch of its inaugural Polygon Fellowship: Class of 2022. Devised in conjunction with DevFolio, the program has been carefully curated to help provide successful applicants with education, funding, mentorship, and support with a wide range of aspects related to the rapidly evolving Web3 industry.
The fellowship is set to occur across eight weeks, during which a total of 50 developers with varying technical skills will attend workshops and masterclasses to help them build Web3 technologies from scratch. The fellowship aligns with Polygon’s broader goal of onboarding millions of developers to Web3 and bringing the technology into the mainstream.
Seeking to encourage more talent to the world of Web3, the fellowship will start in India — targeting the country’s 5.8 million-strong developer community, before expanding to other regions of the world.
Successful applicants will be provided with expert support and mentorship to empower them with the skills needed to develop decentralized applications (dApps) on the Polygon blockchain. Upon culmination of the program, each project will be reviewed and tested to assess its general utility and long-term viability.
As part of the experience, fellows will be placed into small groups alongside some key mentors, who will help provide them with a foundational base about all things Web3. Mentors will assist the applicants by providing them with detailed instructions about building their own projects and utilizing their creativity to build the future of Web3.
Fellows in the beginner group will receive $1,500 each to realize their ideas, while those selected for ‘Web3 Builder Track’ will receive $3,000 — with each investment being dedicated towards resources and building purposes.
During the final two weeks of the course, both groups will attend the Polygon Hacker House in Bangalore to present their ideas and demos to the group.
The beginner program runs from June 13th until August 7th. The builder program starts on July 4th and runs until August 28th.
