According to Cointelegraph, Herodotus has launched a new zero-knowledge proof (ZK-proof) technology designed to improve the ability to access and verify historical data on the Ethereum (ETH) blockchain. The technology uses StarkWare's STARK proof, co-invented by mathematician Eli Ben-Sasson. Herodotus' on-chain accumulator uses storage proof encryption to allow users to verify any data on the Ethereum blockchain without the need for a third party. In addition, StarkWare provides Herodotus with a customized shared proof service SHARP instance to achieve advanced scaling efficiency through recursive proofs. The on-chain accumulator is essentially a proof of cumulative proof, which greatly reduces the time required to verify the Ethereum blockchain and its associated data. Herodotus CTO Marcello Bardus said the technology eliminates the need to traverse the entire blockchain on the blockchain itself.
