Ethereum Classic is the original protocol of Ethereum. As a result of the massive hack on the Ethereum-based DAO, in which around 14% of all ETH in circulation were stolen, a hard fork was proposed to return the stolen funds to their owners. This caused an ideological split revolving around the question of changing previous transactions in the blockchain. Some Ethereum holders rejected the hard fork, and decided to keep using the original protocol, based on the principle that the blockchain is immutable, and cannot be changed.

MOL is developing a blockchain platform for micro-payments. MOL's architecture will be based on the block lattice design used in Nano, and will have a Delegated Proof-of-Stake (dPoS) consensus mechanism that incorporates elements from Directed Acyclic Graphs (DAG). The MOL network is currently powered by the Ethereum-based MOL token.

PLATINCOIN is a Proof-of-Stake coin that is minted instead of mined. Users participate in managing the network by renting hardware space from the project organizers for a period of 36 months. These computing resources will drive the PoS consensus, and the users that rent the hardware will be rewarded with newly minted PLC coins.
