Anduro is a multi-sidechain platform on Bitcoin that was incubated by Marathon Digital Holdings. Anduro sidechains feature Bitcoin Proof-of-Work (PoW) at the heart of consensus through a process known as merged mining. Just by integrating a simple API and running a full Anduro node, any Bitcoin miner could earn Bitcoin-denominated transaction fees, in perpetuity, from each Anduro sidechain at once. Additionally, merged mining should not require additional power consumption.
