Planned: quantum-safe data sampling that replaces KZG and its ceremony.
Why it matters: Removes a quantum-vulnerable piece and a trust assumption at once.
On the map: hash-based, replaces KZG and its trusted setup
Map note, rests on: hash collision resistance + erasure coding (unconditional)
Post-quantum data availability sampling, targeted at strawmap fork J* (around 2028-29)[1]: replace KZG commitments with hash-based commitments, which also removes the trusted setup.
It rests on hash collision resistance plus erasure coding, which is unconditional.
If any of these breaks, this breaks too.
If this breaks, these break with it.
Nothing on the map depends on it: it is an end point of the roadmap.
