Meter.io is a blockchain platform delivering a stablecoin linked to electricity value and energy-efficient mining. It allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter leverages PoW to create metastable MTR for fees and payments. It uses HotStuff-based PoS consensus with MTRG (Meter Governance Token) used to validate transactions and secure the blockchain. Meter can also currently function as an EVM compatible layer 2 sidechain.
