MMB paper is out
Hey Polkadot community!
I’m posting this on behalf of the team that proposed MMB in Ref. 1667. We will use this medium to keep the community informed of the advances of the proposal.
Quick reminder: The Merkle Mountain Belt (MMB) is a novel data structure that improves upon the Merkle Mountain Range (MMR), which is currently used within BEEFY to build a commitment to all finalized blocks and messages. A switch from MMR to MMB in BEEFY will reduce the average costs of proving that anything happened in Polkadot. In particular, it will reduce the gas costs for users of a Polkadot-to-Ethereum bridge.
First big announcement: The MMB paper is out!
We invite researchers and devs alike to check it out, share it, and give us feedback. In it we describe in depth how MMB works and how it will reduce fee costs in Polkadot’s cross-chain bridges. We also describe many other possible use cases for MMB. In fact, we argue that MMB deservers a place in the toolset of any blockchain protocol designer, next to (or instead of) MMR.
We will post further news on MMB here very soon. Stay tuned!
