## Every claim under this term

2 claims across 2 works, 2025 to 2026.

**2025**

- [5225296-018](https://wulfkaal.github.io/claims/5225296-018) [mechanism/evidenced] -- SPoS binds validator votes irrevocably by requiring commitment via hash preimages that are revealed only after a designated period, driving the probability of successful post-facto vote alteration below 2^-128.
  > These schemes require validators to commit to votes via hash preimages, revealed only after a designated period, rendering post-facto alterations computationally infeasible with a probability of success below 2^-128

**2026**

- [7598518-007](https://wulfkaal.github.io/claims/7598518-007) [condition/stated] *(failure mode)* -- The seal is a commitment made visible rather than a lock, because the operator can open the files.
  > Intelligence models increasingly learn from data that earlier Intelligence models produced, and when that loop repeats the rare cases disappear first. This paper preregisters a test of whether a reputation-weighted validator pool, filtering the training data of a recursive replacement loop, keeps those rare cases alive. The outcomes remain sealed until a replication of the original model-collapse result succeeds.
