According to Planet Daily, Polygon has released the Type 1 Prover, the next generation zkEVM prover, which can generate proofs for any EVM chain (side chain, Optimistic Rollup, or even Ethereum itself). Polygon said the Type 1 upgrade will be able to generate ZK proofs for Ethereum mainnet blocks at an average cost per transaction as low as $0.002-$0.003 (more than 36 times faster than any other Type 1 Prover), with the addition of Plonky3 and zkEVM Improvements are expected to reduce costs by 30 to 50 times next year.
