We swapped the @ShieldedCSV and @zerosync_ handles. Socials are moving to the project account, and this one will fade out. If you’re here for the privacy protocol, follow @ShieldedCSV.

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 ⛊ arxiv.org/pdf/2609.32015

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

We are very happy to announce that we have formally verified the techniques of Liam Eagen's eprint.iacr.org/2022/596 in Lean 4, using only the standard axioms: magicgrants.org/2026/09/29/D… github.com/zksecurity/eagen-… 🧵1/6

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.

I filmed a whiteboard session... 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

🧑‍💻 🎥 The recording of today’s dev call. Fans of @liameagen’s magic will especially love this one. (Unfortunately, the video of @robin_linus' whiteboard session got cut off 😕)

OP_TEMPLATEHASH can solve two of the biggest BitVM3 bridge pain points: • interactive deposits → non-interactive • 1-of-n committee for safety → gone robinlinus.com/bitvm448.pdf

Native SNARK verification on Bitcoin would unlock better scalability and privacy via protocols like @Glass_Coins. Looking forward to presenting our progress on a SNARK verifier BIP at Bitcoin Research Day

Replying to @sr_gi
This year we'll have @0xgazelle, @jesseposner and @robin_linus talking about advances in topics from last year's Bitcoin Research Week (PQ, Nested MuSig and ZKP), plus @stevenroose3, @nemothenoone and @nadav_kohen covering hot topics in Bitcoin (Ark, PIPEs v2 and Isogenies).
