Greetings @neonrooks.
What gain to users is achieved whether blocks are full or not? The current rules allow for only a maximum growth of the blockchain at a linear rate.
Arbitrary data impacts full validation by rapid expansion of the UTXO set which, as demonstrated in the recent spam waves, does not necessarily grow linearly. Disk space is also a concern, though secondary.
Who decides which policies to uphold? This should be the decision of each node by its own mempool policy, no?
Consensus is “decided” by 100% of nodes.
Can you define the unneccessary costs and risks of running a node in this scenario? We should be clearly informed of these issues.
These are outlined in the BIP document. Please read it if you would like to understand BIP-110 more deeply. I have also just reiterated them in my reponse to ariard. Please let me know if anything is unclear.
Can you demonstrate an example of payments being unfairly disadvantaged?
Yes, during the recent spam waves, transaction fees often went so high that most monetary use became impractical, due to non-payment spam pricing out payments. This situation is nonsensical for a payment network.
Thank you for your time.
My pleasure. Feel free to reach out to me on X if you need any further clarification.
