What is the real cost of a 51% attack on Bitcoin?

We consider Bitcoin to be immutable. But, even if only theoretically, it is possible to rewrite the ledger with a 51% attack. When ever I have been asked about this I have always said, “yes it is possible, but it would take a military grade budget”
What would be the real cost of doing a 51% attack when factoring the cost of machines, the cost of energy consumption and other indirect/direct cost?

TIL - It would currently cost just $4,646 to perform a 51% attack on bch compared to $680,478 for Bitcoin!

[request] What is the real cost of doing a 51% attack on Bitcoin?

A core value proposition of Bitcoin is that there is one shared ledger across a decentralized network of computers, so if someone tries to retroactively re-write a transaction to say that they received more money then they did the network would invalidate that attempt because it’s inconsistent with the ledger of transactions that everyone else considers valid. But, if you control 51% of the network then you could theoretically do the above. What would the real cost of a 51% attack be when you include the cost of machines, the cost of power consumption and other direct/indirect cost?

Is it true that it only costs ~ half a million dollars to rent enough computational power to 51% attack the bitcoin network? Even if this figure is off by a factor of 10 or whatever, isn't it likely that the Federal reserve would consider such a method to damage bitcoins reputation?

I'm trying to understand what measures, if any, the central banks of the world might attempt to try to keep their control and power of the fiat system.
This is not an attempt to bash crypto, I'm simply intrigued and curious about what steps the central banks of the world might take to try to preserve their power during the advancement of cryptocurrency.
If this particular concern of renting hash power is not concerning to you, are there other concerns about ways that the governments of the world might attempt to hinder or limit cryptocurrency? Or do you think they have absolutely no power to do that? Certainly they can spin the media, but I'm curious about more direct approaches they might take, whether it be legislation or direct intervention of some other sort.

Analysis: Bitcoin Costs $1.4 Billion to 51% Attack, Consumes as Much Electricity as Morocco

Analysis: Bitcoin Costs $1.4 Billion to 51% Attack, Consumes as Much Electricity as Morocco submitted by cybersofts to Bitcoin [link] [comments]

Bitcoin Costs $1.4 Billion to 51% Attack

Calculations and Math (Nov 29, 2018)
Fixed Costs:
The 7 day average of the Bitcoin network hash rate, as of November 23rd 16:00 UTC, is 41,483,931 terahashes. https://www.blockchain.com/en/charts/hash-rate
To acquire more than 50 percent of the Bitcoin network, an attacker would need at minimum the same number of ASICs that are already in circulation.
Network hash rate / terahashes per ASIC = number of ASICs necessary to acquire 50 percent * 41,483,931 network terahashes / 14 terahashes = 2,963,138 S9is * 41,483,931 network terahashes / 23 terahashes = 1,803,649 T15s
Calculations for total current ASIC usage: 2,963,138 * 1.75 (crude estimate accounting for older models) = 5,185,492
Including bulk discount of 10 percent for the size of the purchase and economies of scale.
Infrastructure costs such as housing are a multiple of hardware costs from anywhere between an additional 22 percent to 40 percent, according to the CEO of a large-scale mining operation based in Canada. We will use the low figure to again account for economies of scale.
Variable Costs:
Costs of daily electricity consumption for S9i: * 2,963,138 ASICs * 1320W = 3,911,342,160 Watts * 3,911,342,160 Watts / 1000 = 3,911,342 kWh * 3,911,342 kWh * 24 hours = 93,872,212 kWh per day * 93,872,212 * $0.03 per kWh = $2,816,166 per day in electricity Electricity costs based the low-end of the electricity rates in Washington State, the state with the average lowest electricity costs in the United States: https://www.electricitylocal.com/states/washington/
Costs of daily electricity consumption for T15: * 1,803,649 T15s * 1541 Watts = 2,779,423,109 Watts * 2,779,423,109 Watts / 1000 = 2,779,423 kW * 2,779,424 kW * 24 hours = 66,706,155 kWh * 66,706,155 kWh * $0.03 per kWh = $2,001,185 per day in electricity
Cost of labor and maintenance above electric costs: 10%. This is an estimate based on an interview with two different large-scale miners in Canada and Georgia who chose to remain anonymous.
Average kWh: ((((3,911,342,160 Watts + 2,779,423,109 Watts) / 2) * 24 hours) * 365 days) / 1E12 watt hrs per terawatt hrs = 29.3 TWh
This estimate is short of Denmark’s oft-cited annual energy consumption of 32 TWh, closer to Morocco's consumption of 29 TWh.
Total Costs:
51% attack may require at least 10 days of sustained mining, at a minimum, based on the recent Bitcoin Cash hash wars:
Total cost of S9i attack: $971,814,740 + $30,977,820 = $1,002,792,560 Total cost of T15 attack: $1,808,111,227 + $22,013,740 = $1,830,124,967
Average cost of an attack: ($1,002,792,560 + $1,830,124,967) / 2 = $1,416,458,764

51% attack on Bitcoin´s blockchain would take approx. m278 $ in electricity costs alone BUT spamming the chain to the point of global unavailability costs about $5k
