When Satoshi wrote the first version of bitcoin, s/he made what was almost
certainly an unintentional mistake. A bug in the original CHECKMULTISIG
implementation caused an extra item to be popped off the stack upon completion.

Hi Bitcoin devs,
I'd like to share an idea of a method to increase throughput in the bitcoin
network.
Currently, a miner produce blocks with a limited capacity of transactions that
ultimately limits the global settlement throughput to a reduced number of tx/s.
Big-blockers proposed the removal

reduced settlement speed is a desirable feature and isn't something we need

I'm also very happy to see this proposal, since it gets us closer to having
a mechanism that allows the contribution to feerate in an "unauthenticated"
way, which seems to be a very helpful feature for vaults and other
contracting protocols.

If they do this to you, and the delta is substantial, can't you sweep all
such abusers with a cpfp transaction replacing their package and giving you
the original txn?

Isn't the extreme of this that the merchant tries to lock in gains on the
upswing via CPFP, and users on the downswing, both doing scorched earth,
tossing the delta to fees?
Seems like a MAD situation?

Thanks all for your responses.
so is it a no-go is because "reduced settlement speed is a desirable feature"?
I don';t know what weights more in this consideration:
A) to not increase the workload of full-nodes, being "less difficult to
operate" and hence reduce the chance of some of them giving
It's an interesting idea, presumably it would work w the new package relay.
Scorched earth bidding war is definitely fine to deter this type of abuse.
Need to consider it more thoroughly from all sides tho. CPFP on the server
side generally has a couple of downsides:
* Requires a hot wallet to rece
Another downside is that the sender may not opt into a non-pinnable future
format like "V3 transactions", making CPFP difficult. They may spend a lot
of fees to do this however, so maybe we're really reaching here.

Consider that a miner can also produce transactions. So every miner would
produce spam tx to fill their bricks at the minimum allowed difficulty to
reap the brick coinbase reward.
You might quickly respond with a modification that changes or eliminates
the brick coinbase reward, but perhaps that

Hi Sergej,
Thanks for the insightful posting, especially highlighting the FX risk
which was far from being evident on my side!
I don't know in details the security architecture of Bitrefill zeroconf
acceptance system, though from what I suppose there is at least a set of
full-nodes well-connected
