The main goal of Callisto is to research and develop a reference implementation of a self-sustaining, self-governed, self-funded blockchain ecosystem and development environment. Callisto aims to establish a secure and contribution-friendly environment for further protocol development and improvements. It will rely on a built-in system of smart-contracts to achieve this goal.
Ubiq is a decentralized platform which allows the creation and implementation of smart contracts and decentralized applications. Built upon an improved Ethereum codebase, the Ubiq blockchain acts as a large globally distributed ledger and supercomputer, allowing developers to create decentralized and automated solutions to thousands of tasks which today are carried out by third party intermediaries.
