JKDC: JKDC: That is actually true if you look at the report that showed Nicehash hashrates. There was not enough to rent to attack Zcash.

Actutally that report only shows the direct immediatly available nicehash hashrate. It can not, obviously, include the hashrate that gets shifted if there is demand.

For example: If there have been 50 MH/s available free hashrate for Equihash and let’s say (just fictive) 75 MH/s for lyra and someone buys these 50 MH/s Equihash than automaticlly the nicehash miners software get’s triggered to put more hashrate from other algos that have free hashrate to equihash.

This is just a logical procedure, as the more demand for a given algo is, the higher the price gets, triggering the nicehash software to put more hashrate this algo. Good example have been the continous XVG/Verge attacks on the lyra algo. There have been hours on nicehash where you got up to 30 USD per 1080ti/hour for putting traffic to nicehash lyra.

In short, the live report page about nicehash traffic and available traffic gives only an idea about current immediatly available traffic, but not about possible maximum traffic. If i remember right i once did the calculation if nicehash had enough traffic after shifting all free traffic from algos and i would have been pretty borderline to get enough traffic for equihash. But than again, there are other services out as well, which could provide the missing hashpower, in theory of course.

On the other side, having in mind that with more demand the price as well rises, a possible attack than would have raised mostly from 50.000 USD per hour to up to 100.000 USD per hour as the more hashpower you demand from nicehash, the higher the price gets for the shifted traffci from other algos.

Just a little correction to your statement and that the real time report about available nicehash traffic doesn’t include possible shifting of hashrate, nothing less, nothing more.
