Alright folks, keep on hearing ‘why op_ctv/op_csfs’ so listing use-cases: - better vaults - bonds w/ coupons - better Ark - delegated sigs (oracles) - mining pools What else am I missing? Senior devs curious to hear from ya’ll @JeremyRubin @rot13maxi @reardencode

One of my favorite tricks when looking at bytes in Bitcoin is to look at the *length* of the buffer. Surprisingly, that alone usually reveals useful info: 20-bytes -> most recent hash was RIPEMD160 32-bytes -> most recent hash was SHA256

Take a break from Core vs Knots & brush up on digital signatures. By *far* where the majority of Bitcoin innovation actually takes place, here’s a quick list to get you started👇 ECDSA Multisig Schnorr MuSig2 Frost Roast Adaptor Blind Lamport Quantam-resistant

sBTC is coming soon on Sui! Holders of the 1:1 programmable Bitcoin asset can earn yield, lend, and trade their BTC via sBTC, bridging two worlds into one. 🟧 With @Stacks' sBTC, the Sui ecosystem has even more ways to tap into the $2T in BTC liquidity for DeFi — fast, scalable, and no centralized intermediaries.

How well do you know the history of Bitcoin multisig addresses? While first codified with OP_CHECKMULTISIG in 2011, they've come a long way since then, with the latest P2TR address-type supporting multisigs in both the keypath & scriptpath. Read more about the history below!

Did you know combining public keys was once cryptographically impractical? With ECDSA, nodes had to validate each signature in multisig transactions sequentially, resulting in bloat (e.g., 2-of-3 multisig: ~270 bytes).
