Herodotus introduces on-chain accumulator and StarkWare's ZK-proof technology
Herodotus, a technology firm, has developed an on-chain accumulator that utilizes StarkWare's ZK-proof technology to enhance the ability to access and verify historical data from the Ethereum blockchain. This eliminates the need for a third-party in the verification process.
How does the accumulator work?
The accumulator acts as a cache for storing block headers. If the header is already cached, it can be used for validation. If not, the prover generates a proof to cover the requested block range and adds the block header to the accumulator for future use. This accumulation of proofs significantly reduces the time it takes to verify the Ethereum blockchain and associated data.
Advantages over cross-chain bridges and oracles
StarkWare highlights that storage proofs, like the on-chain accumulator, could revolutionize cross-chain bridges as they eliminate the need for reliance on third-party oracles to track and verify data. This technology aligns with the blockchain principles of transparency and accessibility.
Potential use cases and benefits
The on-chain accumulator opens up several possibilities for applications, including account recovery and automating insurance protocols. With the ability to verify on-chain data, users can trigger actions based on historical events within the Ethereum blockchain. This technology has long been needed to improve accessibility and transparency within the network.
