StarkWare, Herodotus launch tech to verify data from any point in Ethereum’s history By Cointelegraph

A new zero-knowledge proof (ZK-proof) technology is set to improve the ability to access and verify historical data from the blockchain, with deep chain validation cited as a usability barrier of the network.

Technology firm Herodotus has released its on-chain accumulator, which uses storage-proof cryptography, allowing users to verify data from any point of Ethereum’s blockchain without needing a third party. The solution makes use of StarkWare’s STARK proofs, the ZK-proof technology co-invented by mathematician Eli Ben-Sasson.
