About EOS.IO

Published by, EOS.IO is a blockchain protocol that enables horizontal scaling of decentralized applications, allowing developers to efficiently create high performance distributed applications. The EOS.IO software provides accounts, authentication, databases, and the scheduling of applications across multiple CPU cores and/or clusters. This allows for horizontal scalability, replaces user fees with an ownership model, and powers simple deployment of decentralized applications.
