Kaspa uses a proof-of-work (PoW) consensus mechanism called GHOSTDAG protocol, and unlike bitcoin, it allows multiple blocks to be produced simultaneously. This process helps make transactions faster and provides more block rewards for miners, according to a statement from Marathon.

“By mining Kaspa, we are able to create a stream of revenue that is diversified from Bitcoin, and that is directly tied to our core competencies in digital asset compute,” said Adam Swick, Marathon’s chief growth officer in the statement.

The Kaspa token's price has risen nearly 50% this year, while bitcoin climbed 44%. The broader CoinDesk 20 index is up nearly 16% in the same time period.

Marathon started mining Kaspa in September of last year after bringing the first mining computer online. The miner has bought 60 petahash worth of mining machines that can generate profit margins of up to 95%, according to the statement.
