Riot Blockchain, one of the world’s largest publicly traded bitcoin miners, has changed its mining pool to ensure “more predictable results” for its operations after failing to produce the expected monthly bitcoins. According to a statement, Riot achieved record hashrate capacity in November, with computing power reaching 7.7 exahash per seconds (EH/s), 12% higher than 6.9 EH/s in October. However, due to a payment variance in the mining pool it was using, the miner produced 521 bitcoin in November, which was less than the 660 it expected to mine. Mining pools used by publicly traded miners are typically kept private. According to a CoinDesk source, Riot was previously using Braiins, formerly known as Slush Pool, for its mining pool.
