CoinM (CML) is a peer-to-peer cryptocurrency and open-source software project released under the MIT/X11 license. Creation and transfer of coins is based on an open source cryptographic protocol and is not managed by any central authority.[1] In technical details, coinm is nearly identical to Bitcoin.


CoinM was released via an open-source client on GitHub on January 28, 2018 by Jyrki Vierelä The CoinM network went live on January 28, 2018. It was a fork of the Litecoin Core client, differing primarily by having a decreased block generation time (2.5 minutes), increased maximum number of coins.

Differences from Bitcoin[edit]

CoinM is different in some ways from Bitcoin.

  • The CoinM Network aims to process a block every 2.5 minutes, rather than Bitcoin's 10 minutes. The developers claim that this allows CoinM to have faster transaction confirmation.
  • CoinM uses scrypt in its proof-of-work algorithm, a sequential memory-hard function requiring asymptotically more memory than an algorithm which is not memory-hard.

Due to CoinM's use of the scrypt algorithm, FPGA and ASIC devices made for mining CoinM are more complicated to create and more expensive to produce than they are for Bitcoin, which uses SHA-256.[2]

These hash functions can be tuned to require rapid access a very large memory space, making them particularly hard to optimize to specialized massively parallel hardware.
