Bitmain's two mining pools BTC.com and Antpool respectively have 25.5% and 16.5% of Bitcoin's ($BTC) hash rate according to Coin Dance today, giving Bitmain influence over 42% of Bitcoin's hash rate. Though the financial incentive for Bitmain to attempt a 51% attack on the network is limited because doing so will likely negatively impact Bitcoin prices, concerns about Bitcoin's centralization are raised. Mining centralization has been an often-discussed topic, and last week Bitcoin Core developer Matt Corallo published the "BetterHash Mining Protocol(s)" (bip-XXXX) which seeks to decentralize Bitcoin mining.
