Re: [bitcoin-dev] Generalized sharding protocol for decentralized scaling without Miners owning our BTC

I don't get it. At the moment, the number of Bitcoin is fixed (at 21
million) by the geometric decay of the block reward.

Adding any other means of creating coins besides the existing block reward,
or altering the block reward schedule, is extremely likely to be seen as
messing with fixed supply. And not adding another method to create coins
wouldn't work - because then redemptions would have to come out of miner's
block reward, which I don't imagine they're going to share just because you
ask.

The only way you might convince users that adding a second way to mint
coins is not messing with fixed supply, is if there is some kind of proof
that the number of coins being minted is accounted for by past burnt coins.
We could call this 'regeneration'. But then you also need a way to prevent
double-regeneration, in which the same burnt coins are used as proof twice.

And you would also need per-sidechain accounting, so that you can't just
regenerate burnt coins that were originally burnt for sidechain A when all
you have is coins on sidechain B. But where to put all this logic? Building
a system that enforces the accounting for sidechains into Bitcoin, as Lucas
pointed out, is not much different to just building the sidechain itself
directly into Bitcoin.

And if you did assemble all that, what you have anyway is a two way peg,
which I suspect will be isomorphic to the very sidechain proposals you seem
to be criticising/attempting to do better than.
