Welcome to the EOSIO source code repository! This software enables businesses to rapidly build and deploy high-performance and high-security blockchain-based applications.
Some of the groundbreaking features of EOSIO include:
Block.one is neither launching nor operating any initial public blockchains based upon the EOSIO software. This release refers only to version 1.0 of our open source software. We caution those who wish to use blockchains built on EOSIO to carefully vet the companies and organizations launching blockchains based on EOSIO before disclosing any private keys to their derivative software.
EOSIO currently supports the following operating systems:
Note: It may be possible to install EOSIO on other Unix-based operating systems. This is not officially supported, though.
If you are new to EOSIO, it is recommended that you install the EOSIO Prebuilt Binaries, then proceed to the Getting Started walkthrough. If you are an advanced developer, a block producer, or no binaries are available for your platform, you may need to Build EOSIO from source.
Note: If you used our scripts to build/install EOSIO, please run the Uninstall Script before using our prebuilt binary packages.
Prebuilt EOSIO software packages are available for the operating systems below. Find and follow the instructions for your OS:
