Start Decentralising the Easy Way.
Build unstoppable peer-to-peer applications—
Koii makes it possible
Build hybrid smart contracts with Koii
Koii makes peer-to-peer development easy by separating contracts into two parts: consensus rules and executable bundles. Nodes participate in ‘Tasks’, submit ‘Payloads’ and then vote to find consensus.

Start building with Koii

Koii gives smart contract developers the nodes and tooling they need to build scalable, cross-compatible, and unstoppable applications, right out of the box.
