Blockchain


The concept of blockchain is originated from the cryptocurrency system Bitcoin, which was introduced by Satoshi Nakamoto in 2008. The blockchain architecture is built on a decentralized peer-to-peer network and a public transaction ledger. The mechanism for reaching global consensus is based on a consensus algorithm (e.g., Proof-of-Work (PoW), Proof-of-Stake (PoS)). Advanced functionality like the smart contract is supported by certain blockchain. Both industry and academic researchers are working toward the appropriate use of blockchain technology in various fields to enhance the service transparency and availability. For instance, applications of blockchain based identity provider, voting systems, financial services and supply chain management have already been emerged.
