Introducing Plonky2, an exceptional recursive SNARK that stands out for its remarkable speed, surpassing many other alternatives in the field. By combining the powerful features of PLONK and FRI, it brings together the efficiency of STARK and the advantages of SNARK. This includes the ability to verify proofs on the Ethereum network at a low cost, with just the requirement of keccak-256. Moreover, with potential enhancements like EIP-4488 on the horizon, the verification cost on Ethereum could witness a significant reduction.
