Meter is a DeFi infrastructure with a built-in, PoW-based, low-volatility coin, MTR. MTR is a fully-decentralized, permissionless, low-volatility cryptocurrency that eliminates counterparty, regulatory, and oracle risks typically found with crypto- and fiat-backed coins.

Meter employs a unique hybrid consensus protocol that separates currency creation from record keeping.The system uses Proof of Work (SHA256) to create the MTR low volatility coin, making it as decentralized as Bitcoin. HotStuff consensus based Proof of Stake is used to manage the ledger; validators who hold Meter’s governance token, MTRG, approve transactions.This hybrid consensus mechanism makes Meter fast – the system can process thousands of transactions per second, reaching finality almost instantly.

Meter also supports multiple chains and functions as a Layer 2 sidechain for other public blockchains like Ethereum to allow value interaction among different crypto assets.

The Meter mainnet has been live since July 4th, 2020. The block explorer is at https://scan.meter.io Currently the mainnet is operated by foundation nodes, however our testnet is maintained by more than 100 community nodes with full EVM support (the protocol itself supports thousands of validator nodes). We will switch to a fully-permissionless network in Sept/Oct 2020.

We have measured the scaling performance with regular AWS nodes spread out in 5 continents, and the Meter system can sustain 1500 tx/sec with around a 7-second block period. The only performance bottleneck is actually the sequential processing model in EVM, instead of the consensus itself. Basically, one of the cores of the VPS was fully saturated when processing the transactions. This could be optimized in the future for parallel processing models. With such performance, we could complete Reddit's scaling challenge in about 200 seconds without giving up any decentralization.
