Blockchain Developer Lattice Unveils ‘Alternative Data Availability’ Network for Optimism

“We call it alternative data availability, because the transaction data is available off-chain, not on Ethereum. To maintain security with this architecture, that’s why we have the permissionless on-chain DA challenge so that when the data is not available or doesn’t correspond to the data commitment, one can challenge it to be excluded,” Justin Glibert, founder and chief executive officer of Lattice, shared in an email to CoinDesk.
