The decentralized service platform AVA, founded by Cornell University famous computer scholar Emin Gun Sirer, announced the official release of the public testnet Cascade, which is the first of two testnet versions in the AVA roadmap plan. In the first version released, the global verifier network can be added and transactions can be experienced.

The AVA blockchain platform is driven by the Avalanche consensus protocol and is designed to allow anyone to create public or private blockchains that can run smart contracts and can cross-chain. Emin Gun Sirer, a famous computer scholar at Cornell University and CEO of AVA Labs, said, “As an open source project, AVA will actively listen to the valuable opinions of active communities around the world, and is building a solution driven by the needs of potential users. It allows both the license chain and the license-free chain to be expanded, and realizes cross-chain connection. ” Lianwen previously reported that Ava Labs completed a US $ 6 million financing in February 2019.
