A little bit of chit chat…
Thank you for signing up for Cosmos News /// by ZKV! In this inaugural edition, we start with a summary of our latest Privacy in Cosmos event, which took place on Monday January 13th, and featured some of the brightest minds in the space talking about different scalability solutions.
Starting in next week’s edition, we will be sharing the hottest topics around zk, privacy and notable developments in the Cosmos ecosystem summarized in 3 points.
But now let’s jump into our summary of Privacy in Cosmos: Scalability edition event!
Ethereum interoperability is a reality with Evmos and Gravity Bridge
Evmos, the first EVM compatible chain in the Cosmos ecosystem is launching soon
Our first speaker was Federico Kunze Küllmer, co-founder of Evmos, who sees Evmos as the point of entry for the Ethereum ecosystem into Cosmos and has been focusing on interoperability between the two blockchains.
Not only does Evmos enable ERC20 tokens to be represented as Cosmos coins and vice versa, it is also fully EVM compatible meaning smart contracts and DApps from Ethereum can easily be deployed in the Cosmos ecosystem.
Their network fee distribution aims to incentivize all of the 3 major user groups in Evmos- developers, validators, and network users.

Also, Deborah Simpier talked about the Gravity Bridge
Gravity bridge is a purpose-built, neutral and decentralised blockchain for bridging assets between Ethereum and Cosmos ecosystems. It is built by Althea.
A massive benefit of the Gravity Bridge is that bridging assets from Ethereum to Cosmos incurs very low fees by using a batching mechanism to spread the gas cost between all of the participants in the batch. This is important to make DeFi and microtransactions accessible to a wider retail audience.
The trustless setup of the bridge uses the security of the Cosmos network and leans into the decentralisation as it launched with over 100 validators with more to join the set soon.

Talking about Data Availability (DA) with John Adler from Celestia
So, for starters, what is Data Availability (DA)? It’s a complicated topic to be sure. As my colleague Susannah Evan’s defined in the ZKV wrap up blog post about the event:
DA is distinct from data retrievability or storage and is concerned with whether data has actually been published in a blockchain transaction. Additionally, DA is not uniquely attributable because you cannot prove that the data is missing.
In a blockchain network there are certain rules about what constitutes a valid transaction. Celestia’s DA layer orders all transactions, both valid and invalid but transaction execution takes place elsewhere. Data availability sampling is then used to verify the validity of transactions and is possible without downloading all of the block data.
Celestia’s solution, based on fraud proofs, erasure coding and random sample scales best with larger block size as the DA sampling speed is proportional to square root of the block size.

Agoric is making web3 accessible to all js developers
Dean Tribble talked about Agoric which enables smart contracts to be built in javascript which opens the doors to the 10M+ programmers in js, rather than limiting the talent pool to the ~10,000 solidity devs.
But Agoric is not only about just the language,the component model matches ReactJS for safe production of DeFi, NFTs etc. So far, the smart contract platform has been built and the incentivised testnet is complete, including interoperability with other chains.
