I’ve published the Verilog reference implementation of ROOM (Read-Once-Only Memory) — a hardware primitive designed to enforce true one-time key release.
ROOM is modeled after a quantum measurement enforcing the no-cloning theorem: a stored value can be read once under matching metadata predicates, then the register collapses irreversibly, and all subsequent reads return only pseudorandom obfuscation.

The repo includes modules for: • Classical ROOM registers (read-once with collapse latch) • Metadata-gated registers (basis/phase/tags) • Entangled peer-collapse behavior • Collapse-derived entropy harvesting • QKD-style demonstration registers (BB84/E91 emulation)

I’d be interested in feedback from FPGA, ASIC, and cryptography folks — especially thoughts on integrating ROOM with existing PQC protocols.
