One of Meter's goals is maximizing interoperability with other public blockchains. Meter has already achieved backwards compatibility with the EVM (Ethereum Virtual Machine).
Our interoperability goals:
Further improve our Hybrid PoW/PoS + HotStuff Consensus performance.
Enable decentralized value interaction between these blockchains.
In the past year we built a bridge to Ethereum and have partnerships with Elrond and Matic to do the same. Many more similar partnerships are coming, so stay tuned!
