Bitcoin Core developer Greg Maxwell has criticized the “engaging thriller” that concern of a 51% assault on Bitcoin (BTC) entails, arguing that it betrays a elementary lack of know-how in regards to the cryptocurrency.

In a Reddit put up printed on Oct. 5, Maxwell argued that any mechanism cooked as much as mitigate the specter of a 51% assault at all times implies centralization and represents a far higher risk to Bitcoin’s integrity.

Bitcoin’s elementary focus

As Cointelegraph reported beforehand , a 51% assault can happen on blockchains that use a proof-of-work (PoW) algorithm and primarily entails a consumer or group seizing management of the vast majority of mining energy to monopolize management over the community. 

This, specifically, can enable the risk actors to reverse transactions in an try and double-spend. It’s achieved by transacting crypto for fiat foreign money after which rolling again the deed to recuperate the spent crypto whereas pocketing the fiat.

Responding to the query of the best way to mitigate such a risk, Maxwell robustly argued that any such try essentially compromises decentralization on the coronary heart of the Bitcoin mission.

He famous that Bitcoin focuses on fixing the issue of reaching consensus on a secure historical past of transactions. This difficulty can intuitively be solved by establishing the “firstness” of a given transaction, rendering duplicate subsequent operations invalid. Maxwell continued:

“In a very decentralized system ‘first’ is definitely logically meaningless! As an inescapable results of relativity the order which completely different events will understand occasions depends upon their relative positions, irrespective of how good or quick your communication system is.”

Anti-51% fixes ‘centralize the system however simply disguise the centralization’

Maxwell criticized extra centralized techniques — naming Ripple, EOS and IOTA — for resorting to a single occasion figuring out firstness and imposing this on the remainder of the community.

Bitcoin’s essentially decentralized nature as an alternative depends on the “vote” of computing energy by way of mining with out the involvement of any centralized third occasion.

Maxwell argued that any mechanism that will enable to stop the “rigging” of this “vote” — by one occasion or a number of — “would nearly actually allow you to simply substitute mining totally.” He defined: 

“Folks have cooked up 1001 difficult schemes that declare to do it with out introducing centralization, however cautious evaluation finds time and again that these fixes centralize the system however simply disguise the centralization.”

A far greater danger to Bitcoin than the reordering of transaction historical past that 51% assaults might result in, Maxwell concluded, is that:

“The general public utilizing it will not perceive, will not care, and will not defend the decentralization properties that make it priceless over centralized options within the first place.”

As Cointelegraph reported, crypto change pledged to reimburse customers this January after discovering out {that a} 51% assault had efficiently occurred on the Ethereum Traditional (ETC) blockchain.
