Right here’s how a lot a “51% assault” would price for Bitcoin based mostly on the whole hashrate linked to the blockchain proper now.
Value Of A 51% Assault On The Bitcoin Community At the moment
In a brand new post on X, analyst James V. Straten has offered an estimation for the price of a 51% assault on the BTC blockchain. A “51% assault” within the context of Bitcoin is when a single group takes management of greater than 50% of the hashrate on the community and thus, successfully beneficial properties maintain of the blockchain as an entire.
The “hashrate” right here refers to a measure of the whole quantity of computing energy that the miners have linked to the BTC community proper now. The metric is measured when it comes to “Exahashes per second” (EH/s).
Here’s a chart that reveals how the 7-day common Bitcoin mining hashrate has modified over the previous yr:

From the graph, it’s seen that the Bitcoin mining hashrate has noticed an increase lately and has simply set a brand new all-time excessive. The most recent worth of the metric is round 464 EH/s.
Notice that that is simply the weekly common, because the precise hashrate can fluctuate rather a lot day-to-day as some miners could flip off their machines throughout low electrical energy durations, whereas others change theirs on. There are additionally miners increasing their amenities and new ones becoming a member of in, whereas others could also be leaving the community.
As talked about earlier than, a 51% hack would require an entity to achieve management of greater than half of the community hashrate. Assuming that no current mining firm would need to collude with such a malicious attacker, they must carry on-line contemporary hashrate simply barely higher than the present complete on the chain.
For the aim of the calculation, Straten has chosen the present hashrate as 470 EH/s (which is fairly near the most recent 7-day common). As the most cost effective route to realize the required energy could be by renting, the analyst has checked out the price of doing so.
Straten notes that based mostly on latest knowledge, the estimated hourly price to lease about 0.1 EH/s of hashrate is 0.19652 BTC (price about $6,847.08 on the time the analyst made the put up).
Thus, the hourly price to lease Bitcoin hashrate equal to the present community complete (470 EH/s, as talked about earlier) could be roughly 38.485 BTC ($1,340,886.50).
“This estimation assumes the provision of enough hash energy for lease and represents the fee for an uninterrupted assault lasting one hour,” explains Straten. “It’s a theoretical determine, reflecting the expense of renting hash energy at present market charges.”
BTC Worth
Bitcoin had made a push in the direction of the $36,000 degree a few days again, however throughout the previous day, the coin has seen some notable drawdown because it has now retraced again to the $34,300 mark.
