Summary
Marathon announced their Anduro layer two proposal, which is a federated model using a quorum called the “Collective” to manage multiple sidechains. Anduro will be merge mined, similar to RSK, providing POW security for assets issued on the sidechain. The peg and consensus model is similar to Liquid, with a Collective handling governance and consensus through a BFT algorithm. The Collective prevents miners from reordering transactions, reducing centralization pressures. Marathon plans to work towards trustless peg and consensus mechanisms in the long term. Anduro will support two sidechain architectures, one based on Bitcoin (Coordinate) and one on Ethereum (Alys). Coordinate will focus on asset issuance and token use cases, while Alys will port the Ethereum Virtual Machine to a Bitcoin sidechain.
Key Points
1. Anduro is a federated model that makes use of a quorum, referred to as the “Collective,” and is capable of managing multiple sidechains with different architectures.
2. Anduro will be merge mined, providing POW security to assets issued on the sidechain not pegged in from the mainchain and custodied by the federation.
3. The Collective in Anduro comes to consensus on block contents for the sidechain through a BFT algorithm or round robin selection, acting as a shield against centralizing pressures for block producers by taking on the role of actual block construction.
