Applied PQC https://appliedpqc.io/ 2026-08-28T00:00:00Z Where post-quantum cryptography actually stands: what has shipped, what is still a draft, and what breaks when you deploy it. Byte-exact implementations of all four standards. The construction of SHRINCS, a semi-stateful hash-based signature scheme https://appliedpqc.io/blog-shrincs-construction.html 2026-08-28T00:00:00Z SHRINCS demotes SLH-DSA to a fallback path and puts a 548-byte stateful signature on the primary one. What the draft reuses from FIPS 205, what it only reparameterises, what it constructs anew, and what it gives up. Post-quantum migration for Bitcoin layer 2s https://appliedpqc.io/blog-bitcoin-l2-post-quantum.html 2026-07-31T00:00:00Z A Bitcoin layer 2 settles to a base layer it cannot change, borrows consensus from a third ecosystem, and runs a bridge whose trust root is cryptography of its own choosing. Where the post-quantum exposure actually sits, and who can fix each part.
