Bro you are being lied to, sorry. BIP 110 creates two different projects with just a single bigger OP_RETURN transaction. You can bend around it all you want, but this IS going to be hardfork! There is NOTHING in between.
A soft fork is something you can ‘opt-in’ to, but you don’t have to. A hardfork is rejecting transactions that don’t follow the rules.
It kind of makes me tired how still every bitcoiner seems to be uneducated about this “issue”. The only issue is, that this got merged and released whilst being discussed heavily. But the change itself is absolutely the right thing, which should have happened long ago. It’s not that it will be “more Ethereum like” afterwards, it’s actually the other way around, but with less UTXO bloat! Spam is already possible today and it’s already cheaper to do over inscriptions, which are on-chain as well! So if you truly want to go against spam, then you’d have to roll back the taproot update and live with a forever broken lightning network. That will be the REAL shitcoin.
The 4MB Block limit remains. If you buy a 20 TB harddisk AVAILABLE TODAY, your node will be able to eat FULL blocks for the next 95 years, where you’d have to upgrade to a bigger harddisk. Then you buy a 40 TB harddisk for 0.5 USD (because that will probably be a micro-sd card at that point) and you are ready for the next 100 years.
This whole thing is an absolute non-issue, all the problems were already there before core30 and core30 even reduces spam. But the discussion is and was important, pre-merge! I hate bitcoin core for doing that and I support node democracy. But I don’t want to live in Luke Dashjrs distopian shithole world view.
