Key elements in network topology-based lending protocol risk contagion models include: (1) node classification (borrowers, lenders, liquidators) with degree distribution analysis, (2) edge weighting based on collateralization ratios and loan-to-value thresholds, (3) cascading failure mechanisms triggered by margin calls when node health scores fall below 30%, and (4) community detection algorithms identifying densely connected borrower clusters. Simulations show protocols with power-law degree distributions experience 2.7× faster contagion compared to random networks under identical initial shock conditions.

Proof-of-humanity systems ensure fair token distribution by verifying unique identities through biometrics, social media, or decentralized identifiers (DIDs). These systems prevent Sybil attacks, where malicious actors create fake accounts to claim disproportionate rewards. By linking tokens to verified humans, projects promote equitable participation and reduce centralization risks. However, privacy concerns arise from storing personal data on-chain. Zero-knowledge proofs can mitigate this by enabling identity verification without exposing sensitive information, balancing fairness with user autonomy.
