Re: [bitcoin-dev] Block solving slowdown question/poll

Hi, noob question here: Is there a long-term plan for if the block reward drops too low to ensure the security of the network? IIUC miners only make profit from block rewards and transaction fees, and once the block reward drop to zero we're merely hoping that transaction fees will keep mining

Hi, Great to see some work in this direction, here's some thoughts on your keygen scheme: In the scenario where Owner1=Owner2, that is, one of the owners sends some coins to itself, that owner would get to know both x1*s1 and x2*s2=x2*s1*o2_inv*o1, and, because he already knows o1 and o2,

Hi all, We are starting to work on an implementation of the statechains concept ( https://medium.com/@RubenSomsen/statechains-non-custodial-off-chain-bitcoin-transfer-1ae4845a4a39), with particular interest in using the protocol enable the change of ownership (novation) of an individual position

I think the point is to use this proposed extension/standard for a kind of "seed management" function, set it up on an offline device (an always offline laptop, or a modified hardware wallet) where you put the master seed. And then you use this as a kind of seed manager and transcript the seeds

Hello, I propose simplifying BIP-322 down to the single-proof case, and removing some abstractions (e.g. the "actions"/"purposes" stuff): https://github.com/bitcoin/bips/pull/903 Feedback welcome. New version below: ``` BIP: 322 Layer: Applications Title: Generic Signed Message Format Author:
