Blockchain can be used in supply chain management to provide an open source distributed ledger that securely and adaptably manages digital assets. A supply chain uses blockchain technology to allow instant confirmation of transactions without mining fees. It is easy to use, secure with digital signatures, immutable, and assigns aliases instead of addresses. A supply chain has hierarchical permissions and transparency in transactions. While a supply chain is related to blockchain, it is not technically a blockchain due to differences in how data is structured and delays between block updates. It can be considered a transaction chain. Openchain acts as a bridge between blockchain and supply chain by creating tokens that can be redeemed, similar to a sidechain.
