🗒️ Summary of this message: Proposal for a new protocol rule, min_fees, where miners set a minimum fee for the next block to increase network security and incentivize higher fees.
📝 Original message:This will indeed give some power to the miners. But they have no incentives
in posting super high numbers as that means they won't get paid or they
will with a lot of delay.
This is not simply like setting the price for a product that has a fixed
quality. In the case of the mining services, setting the price also means
setting the quality of the product you offer (as higher price = higher
security). This is simply a way to let miners have have a say about the
quality of the product that they offer. They can always set 0 min fees and
settle for the lowest quality/ low price service, or maybe find out that
offering a better product for a higher price actually makes them more
money.

🗒️ Summary of this message: Proposal for a new protocol rule, min_fees, to specify the minimum fees required in the following block for network security and stability. The author disagrees with the idea that people will always coordinate for the optimal outcome.
📝 Original message:Hi shesek,
Minimum fees may not be the right mechanism. However I disagree with the
general idea that "if it's optimal for society to do X then they'll do X".
There's plenty of examples where people fail to coordinate in the absence
of a suitable framework, see the "free rider" problem with public goods or
even the simple prisoner's dilemma.

🗒️ Summary of this message: Proposal for a new protocol rule, min_fees, to specify minimum fees for the following block, potentially bringing equilibrium closer to socially optimal.
📝 Original message:Hello everyone,
I'm relatively new here so what I'm proposing could have already been
discussed, or may be flawed or inapplicable. I apologize for that.
I was picturing a situation where block rewards are almost zero, and the
base layer is mainly used as a settlement layer for relatively few large
transactions, since the majority of smaller ones goes through LN.
In such a case it may very well be that even if transaction amounts are
very consistent, transaction fees end up being very small since there is
enough space for everyone in a block. Users wouldn't mind paying higher
fees as they know that that would increase the network security, however
nobody wants to be the only one doing that. Miners would of course like
being paid more. So everyone involved would prefer higher fees but they
just stay low because that's the only rational individual choice.
Therefore I was imagining the introduction of a new protocol rule,
min_fees, that would work like this:
- the miner that gets to mine a block appends a min_fee field to the block,
specifying the minimum fees that need to be contained in the following
block in order for it to be valid.
- one can also mine an empty block and reset the min_fee, to avoid the
chain getting stuck.
min_fees could either represent the total fees of the following block, or
the minimal fee for each single transaction, as a percentage of the value
transacted. Both seem to have some merits and some potential drawbacks. Of
course min_fees=0 would correspond to the current situation.
It looks to me that this could have the potential to bring the equilibrium
closer to a socially optimal one (as opposed to individually optimal), and
to benefit the network security in the long term. Of course it's just a
rough sketch and it would deserve a much deeper analysis. I was just
interested in knowing if you think that the principle has some merit or if
it's not even worth discussing it for some reason that I'm not considering.
Cheers,
Giuseppe.

📝 Original message:I think the discussion has some anecdotic interest but has zero relevance
as far as any decision making is concerned.
Any extension of block rewards after the current deadline should only be
done if and only if the community agrees that it is the only way to keep
the network secure.
The fact that a mild inflation is sometimes compensated by coin loss is
like a bonus.

📝 Original message:It's the first time I read about the security budget and it definitely
sounds scary to me.
If it only takes a few million dollars to attack BTC and make it completely
unusable for one day, I suppose it's only a matter of time before some
hedge fund actually does it, using a short position to profit from the huge
panic sell wave and global loss of confidence that would result from it.
It seems even cheaper to do than the recent attack to Terra, unless I'm
missing something.

📝 Original message:Bitcoin's finite supply is the main argument for people investing in it,
the whole narrative around bitcoin is based on its finite supply. While it
has its flaws and basically condemns bitcoin to be only used as a store of
value (and not as a currency), I don't think it's worth questioning it at
this point.
Just my 2 sats.
