The recent growth in popularity of blockchains has been primarily fueled by their support of cryptocurrencies and smart contracts. However, a blockchain is primarily a distributed, trustworthy ledger and one of its greatest features is its ability to preserve data in a robust and verifiable manner. In this paper we present a general Blockchain-of-Custody Application proof-of-concept. BoCA allows data to be preserved on the blockchain in a transparent and verifiable way. We present our application and discuss the advantages this approach has over the state-of-the-art, as well as discuss different scenarios in which it could be used.
