Madara blockchains can now use Avail for data availability, reducing the need for compressed data to be sent to Ethereum.
Avail is now an option for data availability on Starknet-based Madara networks, according to a Dec. 20 announcement. The new feature will allow these so-called “layer 3” networks to reduce data publishing costs by up to 90% when compared with using Ethereum for data availability and without relying on a permissioned solution, according to the announcement.
Madara networks publish zero-knowledge validity proofs to Starknet, which is itself a layer 2 of Ethereum. For this reason, they are often referred to as “layer 3s.” These networks use a common sequencer that is decentralized by default. The decentralized nature of the sequencer should help to ensure that transactions cannot be censored, the team claims. Madara chains are customized for specific applications. Mangata Finance, Kakachain, Tobi and Alakazam are a few examples of these custom networks.
Avail is a network designed to handle data availability for the Ethereum ecosystem. If an Ethereum layer 2 uses Avail for data availability, it publishes validity proofs to Ethereum but leaves the compressed transaction data on Avail. This reduces the cost of transactions but also requires Avail to be operating at all times to facilitate deposits and withdrawals. A network that stores transaction data off-chain in this way is called a “validium,” which is often contrasted with a full “rollup” that has higher transaction fees but publishes all data to Ethereum.
