What is DMD Diamond? DMD Diamond is a digital currency that that allows people to send money anywhere in the world instantly, securely and at near zero cost. It focuses on creating a multi entry, high rewards monetary system that empowers people to achieve financial freedom through blockchain based technology. DMD Diamond's conceptual goal is to become an ultra-scarce non-government controlled storage of wealth with software facilities that can increase that wealth over time. Emission Model DMD Diamond Coin rollout is one of the cornerstones of this monetary system. The emission model stays the same as in DMD Diamond 2.0, however, the introduced changes make the emission of new coins smoother and avoid sudden large reductions in yearly interest. In the past DMD Diamond relied on both Proof-of-Stake and Proof-of-Work algorithms to govern the network. DMD Diamond 3.0 will be run by state of the art Proof-of-Stake only, while Proof-of-Work is going to be removed completely. Diamond Masternodes A DMD Diamond network consists of full nodes running as servers facilitating connectivity and transmission of updates. Masternodes is a time tested concept which was originally created to prevent decrease in number of full nodes and incentivize people to keep the network running, decentralised and expanding. Over the years as the technology matured Masternodes became ever more useful and could perform additional network services that go above what a vanilla full node could do.
Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network.

There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
