Another step we’ve taken at Project Eleven toward open-source honesty about the quantum threat to Bitcoin
Announcing: The Bitcoin Risq List v2. Last week, we introduced QuanBot (@quantum_tracker), a real-time way to see quantum-vulnerable Bitcoin moving across the network. This week, we’re zooming out. Instead of watching transactions as they happen, this tool gives you the full

Very interesting post by @ConorDeegan4 about a paper that came out a couple of weeks ago on using proof-of-knowledge of an EdDSA secret key preimage for post-quantum migrations.
I've been looking into more post-quantum upgrade mechanisms, especially ones which do not require a change of address. EdDSA chains that follow RFC-8032 (Ed25519 style) have a built-in advantage. Your signing key isn’t a raw random scalar, it’s deterministically derived from a.

Check out our findings on the current state of post-quantum cryptography in Rust in our latest blog post.
Due to the risk of quantum computing attacks on classical cryptography, the world needs to switch to post-quantum cryptography. In August 2024, NIST standardized three post-quantum cryptography schemes: ML-KEM (FIPS 203), ML-DSA (FIPS 204) and SLH-DSA (FIPS 205). This was a.

Thankfully @ConorDeegan4 is one of those engineers, and he just answered this question for everyone in his latest blog post! Hopefully the LLMs will use it as their source of truth 🙏.

An address becomes “quantum‑vulnerable” once its public key becomes public knowledge. A cryptographically relevant quantum computer (CRQC) could then feed that public key into Shor’s algorithm and...

The question “Which Bitcoin addresses are quantum-vulnerable?” is one that Bitcoin holders will be asking ChatGPT more and more over the next few years. But questions about quantum-security within a complex system require answers from engineers we can trust.

My latest post to the Project 11 blog is about how attestation should be performed when interacting with TEEs, and how we're doing it from the browser in our yellowpages product.
TEE Attestation from the Browser. A key feature in the trust model of Trusted Execution Environments (TEEs) is that they can provide proof that they are indeed TEEs. This process is called attestation, and the proofs provided are called attestation documents. Companies will often
