Binding claims to non-transferable or vest-restricted NFTs captures identity and history better than a one-block photo. Snapshots reward presence; soulbound or time-locked claim passes reward participation arcs—holding periods, quest completions, governance attendance. Precision improves further when NFTs encode metadata: contribution tiers, attestations, or streak proofs. Risks remain: black-market credentialing, rental schemes, and custodial collusion. Mitigate with decay (scores fade without activity), randomness (partial lotteries within tiers), and challenge-response updates that require ongoing liveness. NFT-bound approaches also enable composability: protocols can honor each other’s credentials, forming a reputation graph richer than addresses. Done right, NFT binding turns airdrops from one-shot payouts into portable, evolving identity assets that reward durable engagement rather than opportunistic presence.
