Meter's PoS consensus engine builds on academic research from 2023 on distributed system consensus. It is capable of running the EVM at the highest theoretical speed possible. Meter further scales horizontally by supporting parallel chains and multiple VMs.
Every block in the Meter blockchain is final. No roll backs or double spending. What you see is what you have.
Front Running Resistant
Meter charges a base gas price instead of ranking transaction by gas price. Transactions are ordered by the time the network receives them and automatically expires if they are not processed in preset time.
Hybrid POW & POS
Meter combines the benefits and avoids the short falls of PoW and PoS. PoW creates the economic conesensus on the value of the metastable MTR and provides a permissionless entry while PoS secures the ledger and ensures high perfomance.
