Thank you to everyone on nostr who has been patiently explaining the technical reasoning behind considering increasing or removing Bitcoin Core's default OP_RETURN size limit.

But CCs do charge 1-5% to the seller for the initial ~30 day loan period, which is equivalent to a 13% to 80% APR if you were to compound that period 12x in a year. That's about the same rate as Bitcoin loans.

The hardest Optech newsletters to write are those where we summarize unresolved disagreements, e.g. for or against CTV+CSFS. When everyone ends up in agreement, at least mostly, we can skip describing any arguments and jump to the conclusion. But when there's no resolution, we have to get into the details, try not to miss anything important, and be careful not to summarize in a way that misstates someone's key argument or attributes to them an opinion that they don't actually hold. On top off that, there are arguments that seem weak to me but which probably warrant describing in case I'm missing something. All that extra work is important but it's not my favorite. Also, it makes for long and hard to read newsletters, so sorry about that for next week.
