Bismuth, a digital distributed self-regulating database system whose primary application is currency, and its first application is mining. It comes with a set of DAPPs out-of-the-box. Bismuth is not based on the code of BTC or any of its derivates, it is only inspired by some ideas laid down by Satoshi Nakamoto (BitCoin), Sunny King (Peercoin), NXT and ETH developers. Bismuth does not draw any code from other repositories, instead, it reformulates the cryptocurrency code in its own terms to be easily readable, compatible across all platforms, integrated into business solutions with utmost ease and most importantly open for development to a wide public through its simplicity while minimizing the security risk for custom code implementations. Bismuth is a decentralized transaction platform focused on modularity and open source approach. It comes with default decentralized applications and tools out of the box, not only to be used by everyone but also to be hosted by anyone. These applications are supplied as interpretation engines, which prevents blockchain bloat. Inspired by Satoshi’s whitepaper, Bismuth also offers optional hyperblocks as a pruning mechanism, a system which greatly reduces disk space usage and increases execution speed.
Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
