TxChain: Efficient Cryptocurrency Light Clients viaContingent Transaction Aggregation
This repository contains
txchain-relay- a Bitcoin SPV client Ethereum, implementing compressed inclusion proofs as defined in TxChaindata-generator- a Bitcoin data generator
The txchain-relay also contains a contract leveraging our proposed TXEXISTS instruction to efficiently verify the inclusion of previous transactions in Ethereum.
Ethereum's TXEXISTS PoC implementation can be found below
