Knowchain

Knowchain is a two-layer blockchain platform that provides decentralized applications and real-world transactions with smart contracts and additional information tied along a chain.

The goals of Knowchain are to create an extensive platform for creating and deploying decentralized applications and smart contracts that are enriched with additional information from users and the associated application.
By enabling people to add more information to Knowchain, it aims to remove barriers between the cryptographic world and the real world where transactions need to have sufficient information to perform.
