Key Takeaways:

– London-based startup Herodotus introduces the “on-chain accumulator” tool for Ethereum.
– The tool allows users to read and verify data from any point in Ethereum’s history.
– Developed with StarkWare, the tool overcomes the limitation of validating only the last 256 blockhashes.
– The technology promotes transparency and accessibility in the blockchain community.
– It helps develop permissionless account recovery systems and facilitates insurance protocols.
– The tool utilizes the Stark prover, co-developed by Eli Ben-Sasson.
– Storage proofs are used to confirm the validity of data on the blockchain.
– The tool is compatible with Ethereum and Layer 2 blockchain Starknet.


London-based startup Herodotus has developed a new developer tool called “on-chain accumulator” that allows users to read and verify data from any point in Ethereum’s history. The tool, developed in collaboration with scalability solutions provider StarkWare, overcomes a current limitation in Ethereum that only validates the last 256 blockhashes. The technology utilizes a cryptographic method known as “storage proofs” to confirm the validity of data without requiring a third party. This development is expected to enable the creation of permissionless account recovery systems and insurance protocols that rely on past on-chain data verification. The on-chain accumulator tool was unveiled at the Starknet Summit in San Francisco.
