Polygon upgraded its Type 1 Prover technology, which now allows any Ethereum Virtual Machine (EVM)-compatible blockchains to become Layer 2 (L2) protocols based on zero-knowledge proof (ZKP). 

EVM-Compatible Networks to Become ZK L2 for Ethereum

Polygon Labs announced a major update to its Type 1 Prover technology, with Toposware developers involved in the work. Once updated, the technology enables any EVM blockchain to become a Layer 2 solution in the Ethereum ecosystem and join AggLayer. It’ll also substantially improve the overall performance and cost-effectiveness of the network. 

AggLayer is a ZKP solution by Polygon, which helps connect different networks into a single structure and simplifies interaction with Web3 products for end-users. Polygon representatives announced the launch in late January.

As conceived by the developers, the Type 1 Prover technology will eventually form the basis for transaction validation in protocols created with Polygon CDK. The technology is integrated into the validation tool Polygon zkEVM. The update will potentially speed up transaction processing by approximately 3,600%, with fees per transaction ranging from $0.002 to $0.003. 

When the Type 1 Prover is updated, adding an entire block containing hundreds of transactions to the Ethereum mainnet will cost between $0.2 and $0.5. Besides, the technology will be further developed and optimized, so that the cost of a block in the future will be 30-50 times lower.

Last summer, the Polygon team announced work on a set of updates to create interconnected blockchain networks based on zero-knowledge proof (ZKP). The project was dubbed Polygon 2.0. A few months later, Polygon CDK, a toolkit for developers to create fully interoperable ZK Layer 2 protocols in the Ethereum ecosystem, was unveiled.
