Nearly 70% Of BCH Hashrate is Controlled by Unknown Mining Pools, Is A 51% Attack At Risk?

  • BTC.top formerly controlled 15% of the hashrate, which has dwindled to almost nothing.
  • No information has come from Bitcoin Cash on how this user gained such substantial control.

One of the biggest threats to the cryptocurrency industry is that of a 51% attack, which is the possibility that holding over half of the control of the blockchain. According to recent reports from CCN and data from Coin Dance, it looks like this threat is heavily present on the Bitcoin Cash network, as an unknown miner presently has 69.44% control of the hashrate.

Surprisingly, the miner has managed to take over the hashrate, despite the presence of more significant mining pools, like BTC.top and Antpool. Though BTC.top accounted for close to 15% of the total hashrate on the network last week, that percentage has essentially disappeared. Antpool’s mining presence dropped by 50%.

The takeover got the attention of a supporter of Bitcoin Cash, who posted the current circumstances to Reddit. The post showed followers that the last 24 hours have significantly changed Bitcoin Cash’s network, remarking, “They can’t be up to much good.”

Right now, there still has yet to be a lead on exactly what is going on within the network. However, there is clearly a chance that some major changes will happen that could change the course of the network, if this mysterious miner uses the power for evil, rather than for good.

Will Blockstream’s Watchtowers Help Keep The Lightning Network Safe From Attacks?

The Lightning Network (LN) may be controlled and ordered by Watchtowers in the future. Watchtowers are guided by Blockstream’s c-Lightning team and would be a very important improvement on the Lightning Network, the second-layer scaling solution proposed to solve Bitcoin’s scalability issues.

Lightning Network Controlled By Watchtowers

At the moment, the Lightning network works with fraud proofs in order to avoid channels that steal funds. Watchtowers will solve this issue in a new enforcement proposal for the LN called Eltoo. Offline users can protect their funds by deferring to Watchtowers.

This is not the first time that this solution is proposed or tested. Indeed, Lightning Labs and other developers have been working with it. However, this is the first time that such a solution would be implemented on c-Lightning.

In order to protect users, Watchtowers register information from users and store it locally. At the same time, they would be very useful for those nodes that go frequently offline. Nodes that are run by cellphones and similar devices are generally less stable than others.

The c-Lightning developer Christian Decker explained that these Watchtowers are going to play a very important role when users run an unreliable network.

During the last years, the Lightning Network has been growing as a solution for the scalability issues that are affecting Bitcoin and other cryptocurrencies. However, it still needs some time to be developed and tested before it is able to reach the market.

In order for the new Watchtower solution to be approved, it is necessary for the Taproot Bitcoin Improvement Proposal (BIP) to be accepted by the whole Bitcoin community. It is worth pointing out that some months can pass before the market sees this implementation on the Lightning Network.
