In theory, this attacker owns enough computing power that they could execute a "double spend" attack. They could spend coins in one place, allow the coins to enter the block chain as normal until the required confirmations are met, then fire up their 51% of the miners to craft a fraudulent fork of the block chain in which those coins were never spent, ...

It means "solutions per second" and means the number of attempts per second made at generating a valid block. In Bitcoin, where 1 hash is equivalent to 1 attempt at a potential valid block, it's equivalent to "hashes per second".

You can get a current estimate of this info by running the bitcoin-core full node software and calling the command: bitcoin-cli getnetworkhashps

An attack can only be launched when the attacker have more than 51% computational power.

Better Late than Never. I was asking myself the same question...I thought the hash rate of the network came from Full Nodes observation on Miners...I was wrong. I was looking for this answer on Bitcoin.org, but it's on Blockchain website: https://www.blockchain.com/charts/hash-rate. Look at the methodology at the bottom of the page. Formula is Hash rate = (...

If you can make them fit they have PCI full ribbon cables.depending on the algo/ coin you need lanes. I researched/found this because I was building a folding coin rig which is more computational but it does help with mining.

The Size of the pool does matter. It Has to be big enough to take blocks. So long that it can take blocks at a relative frequency, No pool is going to pay out shares of blocks that they take no stake in if they cannot get a block to begin with. That being said, the smaller of the largest is the best. A block is a block, it pays a set amount, getting that ...
