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

A new zero-knowledge proof (ZK-proof) technology is set to improve the ability to gain access to and validate historical information from the Ethereum (ETH) blockchain, with deep chain validation pointed out as an use barrier of the network.Technology company Herodotus has released its on-chain accumulator which utilizes storage evidence cryptography, permitting users to confirm data from any point of Ethereums blockchain without the need of a third-party. The service uses StarkWares STARK proving, the ZK-proof innovation co-invented by mathematician Eli Ben-Sasson. StarkWare presented Herodotus with a customized developed instance of its shared prover service SHARP, which allows innovative scaling efficiency utilizing recursive evidence. The latter permits a virtual device to offer “evidence of evidence”, by producing evidence of deals or blocks in parallel and actual time and batching them into a subsequent proof.Related: More TPS, less gas: Ethereum L2 Starknet lays out efficiency upgradesAt a slightly more technical level, the accumulator serves as a cache that stores block headers. The particular storage evidence calculation can use it for recognition if the accumulator has a header in its cache.

The technology will basically permit any use to access any point in Ethereums history.” This will be very effective. For the very first time in the history of blockchains people are going to have the ability to show the correctness of any aspect of anybodys on-chain information.” The two teams highlight the potential for storage proofs to build “Web2 equivalent applications” using the pioneering ability to access and verify Ethereum blockchain data autonomously. Account recovery is touted as one possible usage case, where the capability to verify on-chain information might be used to trigger a proverbial dead mans switch, or to automate insurance coverage protocols that use historical on-chain events to activate clever contract payouts.Magazine: Recursive inscriptions: Bitcoin supercomputer and BTC DeFi coming quickly
