EOSIO is the next-generation blockchain platform for creating and deploying smart contracts and distributed applications. EOSIO comes with a number of programs. The primary ones included in EOSIO are the following:

• Nodeos (node + eos = nodeos) - Core service daemon that runs a node for block production, API endpoints, or local development.
• Cleos (cli + eos = cleos) - Command line interface to interact with the blockchain (via nodeos) and manage wallets (via keosd).
• Keosd (key + eos = keosd) - Component that manages EOSIO keys in wallets and provides a secure enclave for digital signing.

The basic relationship between these components is illustrated in the diagram below.

Additional EOSIO Resources:

• EOSIO Utilities - Utilities that complement the EOSIO software.
• Upgrade Guides - EOSIO version/protocol upgrade guides.
