Crypto mining company Marathon Digital (MARA) has announced that it has launched mining operations for Kaspa, an open-source, decentralized and fully scalable Layer-1 protocol that uses proof-of-work as its consensus mechanism, and unlike Bitcoin, Kaspa uses BlockDAG (Directed acyclic graph), which allows for the simultaneous generation of multiple blocks. As of June 25, 2024, Marathon has mined 93 million KAS, which is currently worth about $15 million.
