[bitcoin-dev] Inquiry: Transaction Tiering

Re: Miners not relaying unconfirmed txs... I was saying that this was a good thing from your perspective in wanting to give users the choice on which miners would get to confirm the tx. So then like we don't need to implement any kind of special bloated transaction that is only mine-able by some explicit set of miners... No fork or compatibility problems are necessary, can be completely implemented as an added feature.
Re: "Miners": I don't really like calling them "transaction processors" because in bitcoin, every synchronizing node that verifies signatures is a transaction processor. What sets them apart from full relay nodes is they create "blocks", which are "ledger change candidates" that included transactions and proof-of-work (PoW: deterministic diffusion puzzle solutions). They help create confidence that transactions in blocks will never by double spent by requiring that double spending would need lots of economic resources for someone else to re-perform the PoW.
Given the above definition of a "block", I would be happy calling them "Block Producers"... which does not imply that they do all of the necessary "transaction processing": that all users should be fine with running Electrum wallets or even SPV clients. They produce blocks, but its still up to other users in the network to do "transaction processing": decide for themselves if they want to accept particular blocks.

Thanks, those are valid concerns.

That is the idea. Transaction Processors could source transactions
from the public mempool as well their proprietary mempool(s).

Not so, a user may want to incentivise a specific Transaction
Processor or many. A user can detect this behavior and withdraw his
future business if he notices that his transaction is not included in
a block despite there being transactions with lower fees included.
Remember, the transaction can be advertised to different mempools and
a Transaction Processor could lose this business to a competitor who
processes the next block if he holds it back.
PS: It seems not too late to get rid of misleading terms like "miner".
Block rewards (infrastructure subsidies) will be neglectable for
future generations and the analogy is exceedingly poor.
