Chain
Protocol
A blockchain network with its own consensus and state.
A chain is a blockchain network that maintains its own ledger and rules. Some are sovereign with their own validators. Others inherit security from a base layer by posting data there. Builders should weigh tools, users, and costs when they pick a chain.
