Guy, maybe I need to spend more time on the technical side of things to understand your argument. How is the UTXO set stored in ram? And if UTXO bloat is a problem of ram storage instead of dedicated SSD storage, then isn’t that a huge issue which needs to be solved in order to increase the number of UTXOs anyway?

It seems like your main argument is that it’s a stupid way to use Bitcoin and creates bloat, which I definitely agree with, but I’m confused about how that relates to the issues people are voicing with the fee market. And if these transactions are uniquely causing excessive ram consumption, at what point is my 4gb ram Raspberry Pi no longer going to be able to sync?

bitcoin core keeps a cache of the UTXO set in RAM for fast access.

iirc, there are 94M UTXOs currently. gonna take a hell of a lot more than 1M UTXOs to cause a spike in ram. also, the max number of outputs you could create in a block is something like 13k (back of the napkin math)

How many bytes are UTXOs? Wouldn’t 94M UTXOs @ 140 bytes each be about 1.3GB of ram?

And is there another way to store the UTXO set? How do pruned nodes manage it?

Thanks for the explanation though. I enjoy guys podcast a lot but that explanation may have slipped a bit through the cracks
