My thinking is as follows:
1. UTXO bloat (4 GB -> 12 GB in the last year?) has already increased the growth and hardware requirements (I had to replace my Pi4 8 GB)
2. Bitcoin core has done nothing to fight against it.
3. Now they want to invite more spammers and it's not going to help with Problem1 because it is financially wise to put data in witness than OP_RETURN.
Thanks, let's dive in, shall we?
What issue were you experiencing with the Pi4?
I'm asking because there is a common misunderstanding that the entire UTXO set needs to fit into RAM, but that is not the case. The UTXO set is mostly stopped on disk. You only need a couple gigs of RAM for Bitcoin Core to run decently, although more is certainly helpful. UTXO set growth means slower IBD and generally more disk reads during validation, but it's a graceful degradation, not a cliff.
A general synopsis is that with 8Gb Pi4, I cannot add some other apps on my Umbrel OS on top of Core + Lightning + Electrum and some other apps like Jam, Mempool, Nostr relay and Pi-hole. Thats my point, a slow degradation that has made me upgrade to mini-PC within 4 years.
Rather than diving further in that aspect, what are core developers doing to resist or prevent further UTXO bloat?
What we're doing is significantly improving the performance of Bitcoin Core with many releases.
Maybe you're just expecting a little much out of such a low-powered device?
