The growing number of anonymous miners who process blocks in the Bitcoin Network (BTC) has attracted the attention of several experts, because this is a new trend, since long ago, most of the miners’ groups revealed their identity through a Coinbase parameter each time they found a block.
Now, everything seems to indicate that anonymous miners will expand their processing dominance in the largest mining groups such as Btc.com, Viabtc, and Antpool, because traditional mining operations have yielded an important part of their hash speed.
This change could be important for the Bitcoin network security, as the few miners who joined the big groups have started turning off (shutting) their computers due to the low profitability, which resulted to a decline in the domain of group mining, as they lost processing power.
A Diar report found that Bitcoin mining gains were reduced by 80% in 2018 (from 1.2 billion dollars to 210 million).
Drop in the speed of the mining pools
Several experts have shown concern about the growing number of anonymous miners; But these analysts also clarify that even if miners do not disclose their identity, it doesn’t mean that their source of hash speed isn’t part of a group. The researchers found that the three largest groups in Antpool, Viabtc and Btc.com have had declines in their hash speeds in recent times, even when they added an extra 55% in group resources.
The Bitcoin mining industry is very competitive and the overall SHA-256 hash speed for major public Blockchains has grown gradually every year. Between the two most popular mined currencies, the Bitcoin cash (BCH) and Bitcoin Core (BTC), 41.8 exashashes per second ensuring both chains.
Other specialists said that the trend of anonymous miners has expanded and visible on the BCH network. Nowadays, these miners control more than 22% of the BTC chain and 17% of the BCH chain.
