BITMAIN AntMiner S9k

Quick Take

  • Bitmain’s Antminer S9s contributes roughly 23% of Bitcoin’s total network hashrate, a Coin Metrics research report found
  • The number was calculated based on an analysis of nonce distribution, which revealed that S9s and S7s leave specific patterns during nonce sampling
  • As the third halving approaches, many miners have already upgraded their mining rigs from S9s to the latest models, although S9s may still make sense for those with access to cheap power

Bitmain’s Antminer S9s produce around 23% of the total bitcoin hash power output, new research by Coin Metrics has found.

The company’s research efforts assessed that S9s contributed as much as 78% of the total network hash power in 2018, when the mining hardware product was the best-seller on the market. However, that figure has seen a steady decline since then, while the network share of other miners has risen.
