Ethereum Bridge: trustless and efficient asset transfers among PoW-PoS chains
We are building a bridge for applications to access assets on Ethereum while enjoying fast transactions on Harmony. Our bridge architecture is industry leading, being gas efficient and seamless between Proof-of-Work and Proof-of-Stake chains. Inspired by Flyclient (already deployed in ZCash), our light client uses Merkle Mountain Range (MMR) and epoch syncing. Later we may employ zero-knowledge proofs such as Plonk to further compress the states of these heterogeneous chains.
