Marathon's Anduro: A Layer-2 Network for Bitcoin Atomic Swaps

Marathon Digital Holdings, a publicly traded bitcoin miner, has integrated the decentralized exchange (DEX) network Portal to Bitcoin into its Anduro layer-2 network. This integration aims to enhance utility on the Bitcoin blockchain. Anduro, launched in February, allows for the creation of multiple sidechains on the Bitcoin network. Portal to Bitcoin, formerly known as Portal, facilitates atomic swaps, enabling users to convert assets like ETH to BTC on different blockchains. This technology, while common on other blockchains, is a recent development for Bitcoin. Anduro's sidechains use merge-mining, allowing miners to earn Bitcoin-denominated revenue from transactions on these chains while continuing to mine bitcoin on the base layer. This presents a potential new revenue stream for miners, explaining Marathon's involvement in the project.
