Meshcoin is an experimental peer-to-peer cryptocurrency written in dart programming language that currently employs Proof-of-Work consensus mechanism (we have plans to form a new and more efficient consensus mechanism). Unlike bitcoin, meshcoin makes use of the much more efficient hashing algorithm blake2b instead of the compute intensive SHA256 hashing algorithm currently being used in bitcoin.
