Diamond

DMD diamond blockchain has been one of the longstanding community-run ecosystems, since 2013. Its latest upgrade - DMDv4 comes with the first industry features by implementing a cooperative HBBFT consensus with a delegated PoS election validation mechanism.

This enables the ecosystem to present exciting use-cases such as true decentralisation, censorship resistance, robust security, interoperability, front-running prevention, seamless smart-contract deployment & support, sustainable endless coin reward mechanism, low transaction fees, high throughput, on-chain governance, low carbon footprint, decentralised autonomous organisation (DAO), among others.

It's a layer-1 blockchain, with a finite maximum supply of 4.38 million coins in circulation. DMD diamond coin is three times scarcer than Bitcoin and the list of trading platforms for buying or selling the coin is available on the official website and coinmarketcap.
