Many different types of blockchains and blockchain applications exist. Blockchain is an all-encompassing technology that is integrating across platforms and hardware all over the world.
Beginning at the Beginning: What Blockchains Are
A blockchain is a data structure that makes it possible to create a digital ledger of data and share it among a network of independent parties. Many different types of blockchains exist:
Public blockchains: Public blockchains, such as Bitcoin, are large, distributed networks that are run through a native cryptocurrency. A cryptocurrency (introduced in ssss1) is a unique bit of data that can be traded between two parties. Public blockchains are open for anyone to participate at any level and have open-source code that their community maintains.
Permissioned blockchains: Permissioned blockchains, such as Ripple, control roles that individuals can play within the network. They’re still large and distributed systems that use a native token. Their core code may or may not be open source.
