Post Quantum Data Availability
Proof systems for Reed-Solomon codes and data-availability sampling.
LeanAIR experiment proving a post-quantum Reed-Solomon data-availability commitment with only the essential Poseidon, WHIR, wiring, and row-code checks.

Formal Verification
Specifying the EL state machine as an EL-IR intermediate representation for execution proving.
Formal, executable EVM specification in Sail — one source of truth, with a kernel-interface design and extraction to Lean, Islaris, C, RISC-V and Rocq for proofs, conformance and a zkEVM guest.
