7.8k Core/Knots is about Core removing User options.
IMO, Free and open-source software is about empowering Users.
Knots enables more options to the User.
The current B-Core team needs to reflect on the broader intentions of the Users, and of the bitcoin network itself.

5k The timing attack you were looking for in the last episode was with BitMEX and their 3-of-4 multisig, with 3 keys held by the founders and a fourth vanity key thrown in to give the addresses a cool 3BiTMEX prefix. By watching which keys signed off on daily withdrawals, one could make a good guess about who owned what key. The biggest clue then came when one of the founders Sam Reed was arrested and that pretty much gave away the identity of his key. Because P2SH is a privacy leaking shitcoin unlike Taproot's tapscript, which keeps key combinations and spending rules way more hidden.

4.2k NVK is right. Lightning is not Bitcoin. It should be renamed to Satstr. Sats transmitted by relays.

@Sjors_Provoost is one of the best educators in the Bitcoin space. While I strongly disagree with some of his points in this OP_RETURN episode (see my last 2–3 rant notes for that), it’s still a highly insightful listen—like every episode of Bitcoin Explained.
