📎 Shielded bitcoin protocols like @ShieldedCSV need to post a little data with each payment. Taproot already has a slot for that: the annex. Core just won’t relay it.
Opened a PR to make annexes standard. Policy only, consensus untouched.
Reviews welcome: github.com/bitcoin/bitcoin/p…

The crux of shielded Bitcoin protocols like @ShieldedCSV isn’t the private transfer.
It’s the bridge. Shield in. Unshield out.
So what are the real options?

Exciting work on post-quantum Shielded CSV from researchers at Imperial College London and Orbs!
I’d argue, Shielded CSV is the strongest candidate for scalable, quantum-safe payments on Bitcoin ⛊

GLASS COINS vs SHIELDED BITCOIN
∙ Key architecture and metaprotocol tradeoffs
∙ BitVM vs PIPEs (full comp of bridges)
∙ Cutting through delusion: the case for Bitcoin upgrades

Privacy for Bitcoin.
Without compromising scale.
Going live to talk about Shielded CSV.

There’s only one protocol for Bitcoin privacy that scales to 8 Billion people, and that’s @ShieldedCSV 🛡︎

Bitcoin Wizards love Shielded CSV
Andrew Poelstra of @blksresearch breaks down Shielded CSV: a model in development by Blockstream Cryptography Lead @n1ckler where blockchain validation gets flipped.
Users verify coin history themselves. The chain becomes an ordering layer, not an execution engine.

Excited to share our work on BitVM bridges: A novel trust-minimized protocol to bridge Bitcoins to second layers.
Huge thanks to @lukas_aumayr, @alexeiZamyatin, Andrea Pelosi, @zetavar1, and @matteo_maffei for their amazing contributions 🧡

After months in the mempool, our Blake3 transaction has finally been mined, executing the most sophisticated Script in the chain to date. This marks a milestone in our mission of scaling Bitcoin through proof systems and BitVM.
Big thanks to @MarathonDH for covering the fees!
We just broadcasted the first mainnet transaction having a Blake3 hash lock implemented in Bitcoin Script.
One small opcode for BitVM, one giant script for Bitcoin.

We may have discovered a way for BitVM to do permissionless verification, effectively overcoming its primary limitation!

Last week, at the @SFBitcoinDevs meetup at Stanford, @danboneh introduced me to Winternitz signatures. These are more compact Lamport signatures and can cut the transaction fees for BitVM by more than 50%.
Check out the first implementation here:

Here's a diagram of BitVM's transaction graph to get a better overview of how it works under the hood

New grantee. @ZeroSync_ is our first grantee to work on bitcoin proofs (think of them as zero-knowledge proofs for bitcoin), a mechanic which allows nodes to quickly sync compressed blockchain data without having to download hundreds of gigs worth of people testing new wallets.

Exciting developments in the #Bitcoin ecosystem are paving the way for expanded utility. A groundbreaking example is the recently introduced BitVM by @robin_linus. Our team at @calblockchain explored this innovation in depth. Here's what we found: bitvm.org/bitvm.pdf

Can #Bitcoin handle Turing-complete smart contracts? With BitVM, it can! 🎉
Created by @Robin_Linus, the mind behind @ZeroSync_, BitVM performs most computational work off-chain, ensuring secure and efficient operations with minimal impact.
