Validiums

Sophon network is a Validium L2.

Validiums serve as scaling solutions utilizing offchain data availability and computation to enhance throughput and reduce transactions costs. Their security is upheld by issuing validity proofs on Ethereum, which guarantees accurate state transitions, thereby ensuring the overall integrity of the Validium chain.

Unlike zk-rollups that rely on onchain data availability, Validiums opt for an offchain data availability strategy. This difference not only influences their security profile but also their level of trustlessness. By striking a distinctive balance between operational efficiency and data privacy, Validiums offer new use cases. Validiums allow near-instant withdrawals, enabled by the verification of validity proofs on Ethereum and the provision of Merkle proofs by users.
