Comment on Microsoft Needs So Much Power to Train AI That It's Considering Small Nuclear Reactors
Luctia@lemmings.world 11 months agoI’m not sure if you’re serious, but just in case: that wouldn’t work, mining is really just verifying transactions. So if you’re not doing that, you may earn crypto by “mining”, but you can’t spend it because no-one is verifying your transactions.

Not correct.
Mining is a “proof of work”, in the case of Bitcoin it’s competing to be the first to find a hash that meets certain parameters (difficulty), for a block referencing the previous top one. Whether the new block has transactions in it or not, you get the same reward for being the first one to find and broadcast it.
Verifying is done by every node in the P2P network, both when deciding whether to relay candidate transactions, and when checking whether a new block’s hash meets the mining requirements.
The Bitcoin blockchain has plenty of valid blocks with no transactions in them (part of a speculative mining strategy used by some to get the block reward faster than others).
The whole scheme works the same with any other kind of “proof of work”, as long as the nodes relaying the new block can check whether the work happened or not (there are many ways in which that could be accomplished).

I mean, yeah. I knew most of that, but I just wanted to keep it short and simple.
I don’t really understand how it would work with AI training. If your computers are working on training AI instead of finding blocks, I don’t see how you can support transactions. Just sounds like distributed computing with rewards to me, where you might be able to cash out at some central portal or smth, but you can’t send other people that money directly (at least not over a blockchain, but would be possible vis that portal maybe, although, again, that wouldn’t be a blockchain).

There is no “finding blocks” in Bitcoin, it isn’t Minecraft. Miners work on “finding a better hash”, for whatever block they want to propose. The two actions, creating a block, and working on finding a hash, are separate.
In a “proof of training an AI” blockchain, there would still be a hash linking one block to the previous one, just the proof for accepting a new block would no longer be looking for another (useless) hash.
