Bismuth is a decentralized trading platform focused on a modular and open-source approach. It comes with default decentralized applications and tools not only available to everyone but hosted by anyone. These applications are provided as interpretation engines, preventing blockchain bloat. Inspired by Satoshi's white paper, Bismuth also provides an optional superblock as a pruning mechanism, a system that drastically reduces disk space usage and increases execution speed. On-chain messaging and data storage are available in public and encrypted form. Along with Tor support and a transactional hybrid decentralized application, Bismuth offers top-of-the-line privacy features.
