Blockchains can be used to create digital currencies like Bitcoin, but also have applications beyond currency like decentralized applications, digital assets, and identity systems. A blockchain is a distributed ledger of transactions that is shared among members of a network and includes cryptography to allow for decentralized consensus on the ledger without the need for a central authority. Sidechains are blockchains that allow digital assets like bitcoins to be transferred between different blockchains while maintaining the same asset.
