A Validium is a specialized blockchain scaling solution designed to improve scalability by making use of offchain data availability. This approach offers several advantages, including enhanced privacy and reduced transaction costs.

Avail serves as Sophon’s data availability layer, meaning most data is stored and processed on Avail’s blockchain. This reduces costs and improves performance as the burden on Ethereum L1 is much lower. Since Avail is designed to scale with an increase in user activity, it means that Sophon’s own blockchain is able to support thousands, or even millions, of users.

Key Features of Validiums

Offchain Transaction Processing: Validiums process most transactions offchain, reducing the load on the base layer. Only a limited set of transaction data is published to the Ethereum base layer, optimizing performance and lowering costs.

Validity Proofs: To ensure the integrity of offchain transactions, Validiums use validity proofs on Ethereum Layer 1. These proofs ensure that the transaction data is trustworthy and has not been tampered with.

Transaction Verification: A validity proof is attached to every batch of transactions before it is published on the Ethereum base layer. The Ethereum network only accepts and verifies these transactions if they are accompanied by a valid proof, confirming the correctness of the data.

Sophon and Validiums

Sophon leverages Validium technology to provide an efficient, scalable solution. It will be implemented on the ZKsync Elastic Chain, bringing the benefits of Validium’s offchain processing and privacy features to the ZKsync ecosystem.
