Useful and interesting data presentation
From 3 comments
Looks great, nice work, keep it up! One small improvement in my opinion would be to make the columns sortable- especially the 1hr attack cost.
fru2013 on HNVery interesting data. Are you planning on making it available via an API?

Objections
Estimates ignore the cost of buying hardware and rising rental prices, so attacks on large coins are unrealistic
From 2 comments
This is a totally misleading calculation for the largest currencies. It's literally quoting the spot price for what's available on NiceHash and then dividing by the fraction…
HaseebQ on HNDoing a 51% attack on a major coin, and actually profiting from it, is much more complicated than this chart implies. Here are some of the problems you'll run into: 1. NiceHash…

Block rewards are excluded, so attack costs are overstated
From 2 comments
It's important to note that this doesn't include block rewards, so these attacks are all actually less expensive than shown.
pietroglyph on HNIt would be interesting to add the currency rewards the attackers would gain from the hashing process. I bet the cost may be greatly reduced, and may even make the operation…

Some coin entries are wrong, such as Peercoin and Komodo
From 2 comments
This is incredible! What actually stops me from launching such an attack on something like Einsteinium? One problem I found w/ the website: you have included Peercoin, even…
hoschicz on HNOne coin I've seen is wrong is Komodo. It uses DPoW which is a completely different type of security scheme https://wiki.komodoplatform.com/wiki/Delayed_Proof_of_Work_(dPoW) even…

Add more coins such as Decred and Cardano
From 2 comments
You should add Decred to the list. It would be nice for people to see the increased cost of a 51% attack for a hybrid PoW/PoS coin.
lucasp on HNI'm curious were Cardano ADA would be on this list. It seems to be one of the more thoughtful designs, and also a recent addition to the list of coins.

Questions
Can NiceHash be used to run custom mining software for double spends
From 1 comment
Does nicehash let you run custom mining software to make adjustments to how it handles your transactions (permit double spend) or change the algorithm (like the verge attack)?…

Does attack cost rise linearly with time
From 1 comment
Does the cost of a 51% attack rise linearly with time? Is this right? Cost of 24h attack == 24 * (Cost of 1h attack)
