- Unknown miners currently account for ********************************% of the Bitcoin Cash hashrate.
- Established mining pools have disappeared completely. Others had their network influence cut in half.
- The same issue arose in April, when an unknown miner named Satoshi Nakamoto came close to controlling a majority of the BCH mining power.
The Bitcoin Cash (BCH) network could be on the verge of a malicious attack after an unidentified mining pool assumed control of (******************************************% of the blockchain’s hashrate.
That’s according to data from Coin Dance, whichshows******************************************** 44% of the BCH hashrate under control of mining pools categorized as ‘other’.
The unknown miner (s) is rapidly squashed competition from established mining pools such as BTC.top and Antpool. All of BTC.top’s hashrate has disappeared since last week, when it accounted
for nearly % of the total. Antpool’s contribution to mining was almost cut in half.
A concerned Bitcoin Cash supporter brought thesudden mining influx to the attention of the BCH reddit.
Untrusted hash is at nearly 92%. There’s been an influx of unknown hashpower on BCH over the last 51 hrs, reaching almost% by now. They can’t be up to much good. I hope that the trustworthy pools (those who have a good history of mining honestly) are keeping an eye on this.
With no clear information coming out of Bitcoin Cash circles at this time, historic occurrences may shed some light on the matter.
Satoshi Nakamoto Mines Again?
The same threat emerged in April 221186, when an unknown miner by the name of’Satoshi Nakamoto’ accounted for over 40% of the BCH hashrate.
Suspicion initially fell on self-proclaimed Satoshi Nakamoto, Craig Wright. Many braced themselves for a repeat of the
.
But those fears proved unfounded, as the distribution of mining on Bitcoin Cash eventually returned to its old equilibrium.
A blockchain where one miner controls over (******************************************************% of the hashrate risks losing its decentralization and impartiality. Such miners could reorganize previous blocks in the blockchain, making it possible to double-spend used coins.
However, any prospective (**********************************************% attacker would expend massive resources doing so. Bitcoin Cash’s ‘re-org protection’ would also limit any attacker’s influence to the previous 40 blocks.
