It is unknown exactly who mined the majority of the supply, however, more than 33% of Pirate Chain’s supply was mined through piratepool.io. Piratepool.io was the first mining pool for Pirate Chain and launched days after Pirate Chain. From a November 2018 snapshot of piratepool.io, ARRR’s network hash rate was 102.96 MSol/sec with piratepool.io’s hash rate making up the majority at 91.90 MSol/sec. 233 unique miners were mining on the pool. Once other pools launched, piratepool.io typically had fewer than 100 unique miners. This snapshot from January 2021 shows only 43 miners and average hash rate making up only ~6.5% of the total network hash rate. While this sounds like a significant shift, the majority of supply was already mined. Piratepool.io used to list z-addresses of miners because Webworker was too lazy to remove miner addresses from NOMP.
