The held Bitcoin Cash and Bitcoin SV halvings had a “dramatic effect” on both forks, increasing the risk of attack by 51%, according to Arcane Research analysts. The share of the BCH and BSV hashrate in the aggregate indicator of the SHA-256 algorithm has more than halved.
The share of Bitcoin Cash decreased from 3.4% to 1.5% - by 56%, with Bitcoin SV - by exactly 50%, from 2.4% to 1.2%.
This increases the risk of an attack of 51%, as indicated by the abnormal behavior of the rate of extraction of blocks, noted in Arcane Research.
After halving, a new BCH block appeared on average after 19.5 minutes against 10 provided by the algorithm. The speed of generating blocks reached the planned indicator after 144 blocks - this is due to the mechanism of its correction by complexity. However, the volatility of the indicator remains much higher than before halving.
Most often, 2-3 blocks per hour are generated, and approximately every 7 hours, acceleration occurs, reaching in some cases 30 blocks per hour. According to experts, as a result of a drop in the hashrate, major miners gained more control over the network and the ability to play with the complexity adjustment algorithm. As a result, they thus "squeeze" the maximum possible number of blocks per unit of energy consumption, reducing the cost of coin production.
Against the backdrop of a drop in the hash rate of forks, market participants noted the outcome of their miners in the Bitcoin network, the indicator of which after BCH and BSV halvings grew by about 15 EH / s. But, according to analysts, migrants could not contribute a significant share to this - the mining capacities that left the forks network are 3 EH / s.
Accordingly, experts concluded that a possible reverse flow of miners after a bitcoin halving in May will not affect the network of the first cryptocurrency.
A problem for bitcoin may be a decrease in the speed of generating blocks, as shown by forking halvings. At the same time, their indicator returned to normal relatively quickly came because it is adjusted through 144 blocks. At BTC, this happens every two weeks or 2016 blocks, noted Arcane Research.
Previously, researchers from Coin Metrics previously drew attention to this problem.
Expert Opinion on the Possible Impact of the Upcoming Block Reward Reduction on Bitcoin Price
Experts... Experts... Experts...
There is an history behind the fork of Bitcoin cash from Bitcoin core.
In 2014 - 2016, Blockstream, a company founded by recognised developpers in the Bitcoin community , got $21M then $55M in foundraisings in which some companies like AXA, Horizons Ventures and Digital Garage participated massively. The goal was implementing the vision of the founders regarding the "side chains" technology.
These side chains could only be relevant and useful if the main chain (Bitcoin) was unable to scale and, consequently congested. If the main chain is able to scale, the side chain technology is just a useless complicated gas factory. So in order to prevent scaling, all the promoters of the various measures which could have tended to the scaling of the network and its decongestion were censured: removing accounts on a forum controlled by one of the main developers of the team "Bitcoin core" and other malfeasance. A true censorship, well organized ...
This was the basis of the bitcoin cash fork : on one hand people whose economical interest was in the non-scaling of the network which justifies their side chain technology, on the other hand people who are convinced of the rightness of the on-chain transactions which are possible with (and need) the network scaling, begining with rising the block size.
Faced with this, an honest adult must take a stand and put his hash power on the chain which looks fair to him. Instead of that, we see big amount of hash power going from the Bitcoin core chain to the Bitcoin cash chain and back... Same between Bitcoin cash and Bitcoin SV. No comment...
The only thing I can deduct is : the majority of the "big" miners are not honnest adults, but they are mainly interested in $$. Or they all are beotians thinking that everything is equal !
This is not a good signal for the future of the humanity.
Surprisingly (!) no expert noticed that !
