The developers at Polygon Labs have introduced the idea of a type 1 prover that enables EVM networks to incorporate scaling technology utilizing zero-knowledge proofs (ZKP).
With this solution, a variety of blockchains, including sidechains and Optimistic rollups, can be transformed into validiums, a specialized form of L2 networks with ZKP, without the need for hard forks.
Contrary to ZK-Rollups, which transfer evidence of multiple transactions to the Ethereum network, Validiums only store ZKP on the main chain, while the transaction data remains off-chain.
This implementation is expected to increase efficiency and decrease transaction costs, according to the developers.
The shift to the ZK network has the potential to bring advantages to L2 projects, including the elimination of the seven-day withdrawal waiting period associated with Optimistic rollups solutions.
The first type prover is scheduled to be released before the end of 2024 and will be included in the Polygon CDK. Polygon Labs also presented the AggLayer blockchain aggregation layer, which is set to launch in February.
