StarkWare, Herodotus launch tech to verify data from any point in Ethereum's history
Storage Proofs could prove useful for services like account recovery tapping into the ability to access and verify historical Ethereum data. A new zero-knowledge proof (ZK-proof) technology is set to improve the ability to access and verify historical data from the Ethereum (ETH) 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 the need of a third-party. The solution makes use of StarkWare’s STARK proving, the ZK-proof technology co-invented by mathematician Eli Ben-Sasson. StarkWare presented Herodotus with a custom built instance of its shared prover service SHARP, which enables advanced scaling efficiency using recursive proofs. The latter allows for a virtual machine to provide “proofs of proofs”, by generating proofs of transactions or blocks in parallel and real t...
