Single Mining Pool Gains 50% of Bitcoin Cash Hashrate



Bitcoin Cash mining centralization has reached a stage the place only one pool is controlling half of its hashrate, in line with Coin Dance.

The crypto statistics service discovered that BTC.TOP mining pool, a China-based personal entity, took over as excessive as 50.2% of the complete Bitcoin Cash community in some unspecified time in the future right now. It contributed the hashrate of 679 Peta-Hash per second in opposition to different main competing swimming pools together with BTC.com (257 PH/s), ViaBTC (215 PH/s), AntPool (125 PH/s), and Bitcoin.com (187 PH/s).

Bitcoin Cash and Centralization

The notable enhance may have taken place because of variance however, on the identical time, it threatens the Bitcoin Cash community with a possible 51% assault situation. The Roger Ver-led blockchain venture has been criticized earlier than for failing a “stress test,” performed on the behest of an nameless developer(s) often called Bitpico. Evidence confirmed that 98% of all the Bitcoin Cash nodes were sitting on the same server rack which uncovered the coin to seizures and safety threats.

In early 2018, Alex Simons, the identification division chief at Microsoft, discovered that rising block dimension reminiscent of these carried out by the Bitcoin Cash workforce threatened decentralization greater than second-layer scalability options like Lightning Network.

“While some blockchain communities have increased on-chain transaction capacity (e.g. block size increases), this approach generally degrades the decentralized state of the network and cannot reach the millions of transactions per second the system would generate at world-scale,” he had mentioned.

What’s Next for Bitcoin Cash

The central side of any decentralized blockchain venture is its means to protect the system in opposition to central management. In a worst-case situation, malicious mining entities may mix their hashrate output to kind a steady coalition. It may make them forestall transactions from getting confirmed; it may enable them even to reverse the confirmed transactions or spend one legitimate token twice by creating a brand new chain or by altering outdated blocks.

Bitcoin Gold, for example, suffered a 51% attack on its community in 2018 the place attackers double-spent BTG tokens for a number of days. They finally stole $18 million value of Bitcoin Gold tokens, in line with the BTG/USD alternate fee on the time of the assault. In August 2016, two Ethereum-based crypto initiatives, Krypton and Shift, additionally suffered 51% assault on their networks.

In some circumstances, mining swimming pools which unintentionally crossed the 50% hashrate barrier voluntarily decreased their computing energy with the aim of redistributing it to different mining swimming pools. GHash.io, for example, had exceeded 50% of the bitcoin’s computing power in July 2014 however decreased it again to 40% after going through a neighborhood backlash.

What BTC.TOP may do is what GHash.io had carried out in its time: let go of some of the computing energy to reinject belief within the Bitcoin Cash community. If it doesn’t cut back, the digital foreign money may undergo vastly as buyers’ sentiment wears off.
