Rippled - Decentralized cryptocurrency blockchain daemon implementing the XRP Ledger in C++

•    C++

---

Ripple is a network of computers which use the Ripple consensus algorithm to atomically settle and record transactions on a secure distributed database, the Ripple Consensus Ledger (RCL). Because of its distributed nature, the RCL offers transaction immutability without a central operator. The RCL contains a built-in currency exchange and its path-finding algorithm finds competitive exchange rates across order books and currency pairs.

Zcash - Internet Money

•    C++

---

Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Bitcoin and most cryptocurrencies expose your entire payment history to the public. Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.

Vertcoin - Decentralized currency owned by its users

•    C++

---

Vertcoin is a digital currency that can be sent between people over the internet. Vertcoin (VTC) stays true to the original vision of cryptocurrency: a financial system owned by its users, the people’s coin. Vertcoin is not controlled by large banks or mining hardware manufacturers and can be mined by anyone profitably. Fairly distributed without a premine, ICO or airdrop, Vertcoin is developed by community members working as volunteers and the project is wholly funded by donations. A finite resource similar to gold, you can rest assured that Vertcoin will keep your money safe from vested interests and ensure that transaction fees are proportionate and shared between a large number of miners. With Vertcoin, you can truly be your own bank.

CryptoKernel - A modular kernel designed for implementing blockchain-based digital currencies

•    C++

---

CryptoKernel is a C++ library intended to help create blockchain-based digital currencies. It contains modules for key-value storage with JSON, peer-to-peer networking, ECDSA & Schnorr key generation, signing and verifying, big number operations, logging and a blockchain class for handling a Bitcoin-style write-only log. Designed to be object-oriented and easy to use, it provides transaction scripting with Lua 5.3, custom consensus algorithms (e.g Proof of Work, Authorised Verifier Round-Robin) and custom transaction types. We have used Cryptokernel to implement an experimental digital currency called K320. Its name derives from its monetary policy – Milton Friedman’s K% rule at a rate of 320 basis points or 3.2% growth per year (https://en.wikipedia.org/wiki/Friedman%27s_k-percent_rule). This known rate removes the need for trust in the decisions of a central authority, making monetary supply policy completely transparent. K320 is designed to build up the initial money supply relatively quickly then switch to the K% rule for monetary growth.
