Herodotus

Herodotus is building storage-proof technology to enable synchronous cross-layer data access between Ethereum blockchains. It aims to provide smart contracts with synchronous access to on-chain data coming from other Ethereum layers. Our stack combines storage proofs with zero-knowledge proofs. That is in order to enable cross-domain data access between Ethereum layers and make contracts deployed on those self-aware. Our solutions allow the reading and processing of on-chain data (both historical and current). To keep it short, our tech allows developers to build contracts that are able to read L1 State on L2s, L2 State on L1s, and L2 State on L2s in a fully synchronous manner removing the need for asynchronous messages being sent back and forth.
