**2019**

- [3441904-042](https://wulfkaal.github.io/claims/3441904-042) [failure/argued] *(failure mode)* -- Reputation based metrics were ineffective in centralized governance systems because before blockchain, reputation could not be stored autonomously, anonymously, and transparently, so it was not a reliable predictor of actors' future actions.
  > Before the emergence of blockchain technology, reputation could not be stored autonomously, anonymously, and transparently. Accordingly, reputation was not a reliable predictor of actors' future actions in centralized governance systems.

**2025**

- [5886442-033](https://wulfkaal.github.io/claims/5886442-033) [design/argued] *(failure mode)* -- Network congestion externalities and Sybil attack vulnerabilities require the deliberate reintroduction of micro frictions, such as tokenized tolls or proof of personhood protocols, in order to preserve credible signaling in hyper scale agent populations.

**2026**

- [6192998-001](https://wulfkaal.github.io/claims/6192998-001) [failure/argued] *(failure mode)* -- Reputation systems that depend on persistent identity collapse in decentralized settings because agents can create new identities at no cost, so a poorly performing agent abandons its account and starts fresh, a practice known as whitewashing.
  > First, the identity problem: Reputation systems built on persistent identity5 collapse when agents can costlessly create new identities. A poorly-performing agent simply abandons their account and starts fresh, a phenomenon known as whitewashing.6
