EthFor: Forensic Investigation Framework for Ethereum Blockchain

The use of blockchain technology has become increasingly popular for protecting data storage and transmission through decentralised, peer-to-peer networks. This technology is essentially a synchronised decentralised database managed by Distributed Ledger Technology (DLT), which shifts trust from a centralised network to a completely decentralised network of nodes. As a result, information is securely preserved and transmitted across numerous nodes spread across wide areas, ensuring that transactions remain private, secure, and immutable. Blockchain offers various benefits, including traceability, accountability, transparency, and provenance of recorded transactions on the ledger. Therefore, this study proposes a forensic investigation framework for Ethereum blockchain.
