Polygon Will Launch Avail Testnet in Q2

Polygon announced that it will launch a testnet for a new blockchain called Avail, an extensible blockchain network, in the second quarter of 2022. Avail will be a standalone network under the Polygon umbrella, helping to host and verify off-chain data for blockchains that have integrated with it. And Avail will focus on improving the scalability of blockchains both within and outside the Polygon ecosystem. The team said Avail will serve as a “data availability layer" for Ethereum's Layer-2 solutions — Optimism and Validium — and other zero-knowledge scalability solutions offered by Polygon, to help contribute to their data requirements. Polygon Avail will work quite differently from popular blockchain networks. It will use “transaction ordering” based on a couple of cryptographic protocols — called GRANDPA and BABE — for data validation and consensus.
