Reading: Bitmain Approaching 51% of Total Bitcoin Network Hashrate Kyle Baird · @CryptoBizzle | Jun 24, 2018 | 13:00 Bitcoin Mining giant Bitmain has mined 42% of all Bitcoin blocks this past week, steadily moving closer to controlling a majority 51% of th network hash rate.  ASIC manufacturer and cryptocurrency mining giant Bitmain — claimed 42% of the total blocks found on the Bitcoin network from the past week. BTC.com and AntPool, which are both owned by Bitmain, currently comprise 26.6% and 15.3% of the network hash rate, respectively.

Bitmain Technologies Ltd. — the Beijing based Bitcoin mining company reported astonishing profits in 2017, taking in between $3 and $4 billion.

Bitmain has a big leg up on its competitors by manufacturing and using its own products in the mining process. It manufactures application-specific integrated circuits (ASIC) miners that are able to mine Bitcoin at a faster rate than high-end graphics processing units (GPU).

It also operates mining pools, where miners can join their efforts and ultimately cut down on their mining costs — as well as offering cloud mining services that allow miners to remotely rent out mining power from its mining farms. Bitmain also mines Bitcoin Cash (BCH) with its ASIC miners — as BTC and BCH run on the same algorithm. If Bitmain were to halt mining BCH and instead used 100% of its resources for mining BTC, it could theoretically reach around 45% of the total Bitcoin hash rate.

This is quite close to the majority 51% number. This would theoretically put Bitmain in position to perform a 51% attack on the Bitcoin network to censor transactions or perform double-spends. Read more from bitcoinist.com…
