According to Financemagnates.com, Bitcoin mining company, Bitmain, has now control over 45 percent of the computing power on the Bitcoin blockchain, worryingly close to the dreaded 51 percent threshold.
In addition, sources close to the Chinese Bitcoin mining industry believe that Bitmain has a similar “unofficial” relation with mining pool BTC.TOP, which controls about 12 percent of the total network hash rate.

51 Percent Attacks The so-called over 50 percent or 51 percent attack is a security concern for Bitcoin though not one that is easy to carry out. The increasing difficulty of mining Bitcoin has meant that miners get into pools to harmonize their computational power.

Moreover, in 2014 a mining pool briefly gained 51 percent of the overall bitcoin mining computational power — how the bitcoin ledger of transactions is calculated. Should a pool maintain a 51 percent majority, its members could cheat the system by issuing false transactions.
Bitcoin mining software is how you actually hook your mining hardware into your desired mining pool. You need to use the software to point your hash rate at the pool. Also in the software you tell the pool which Bitcoin address payouts should be sent to.
Bitcoin is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network.
For example, if the mining pool operators will tweak their mining rigs between 10-20 percent for a period of time then the operators will have an incentive to be honest and earn reputation as tokens in addition to mining incentives.
Mining pools control a significant proportion of the total computational resource of bitcoin blockchain. Risks of a 51 percent attack on the network increases if any mining pool controls a majority of the total hash rate of the network.
Especially considering the recently released Bitmain IPO prospectus that states Bitmain controls 37.1 percent of Bitcoin’s mining hash power, CryptoNote’s forward-thinking approach to ASIC dominance is largely corroborated in that 51 percent attacks may eventually be feasible, however unlikely.
A 51% attack refers to a sabotage on a blockchain, like for example bitcoin. It is important to note that this type of attack is hypothetical and has (thankfully!) not occurred yet. This sabotage can be carried out by a group of miners that control more than 50% of the network’s computing power (also called hash rate).
One such place is Sichuan, which has of late become known as ‘the capital of bitcoin mining’. It is a home of the world’s largest bitcoin mines. Miners set up mines in the area owing to its abundance of hydropower, ideal for the high energy needs of the machines needed for cryptocurrency generation.
A 51% attack occurs when the total processing power (hashrate) of a proof-of-work network is majority-controlled by one entity or group of entities. This enables them to carry the blockchain forward with transactions that may not be legitimate; i.e. transactions that would essentially double-spend units of value.
