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.
