Real consensus, not a thin LLM wrapper: every claim is first run through a # deterministic static-pattern scan (plain Python, same on every validator), # and only the *semantic* validity/severity judgment is delegated to an LLM, # wrapped in gl.eq_principle.prompt_comparative so validators must agree on # structured fields (is_valid, severity), not on free text. # 2. No same-block payout: an approved claim enters a challenge window before # funds move, so a sponsor can dispute a bad LLM call before money leaves # escrow. Disputes are themselves resolved by a second, independent # consensus round. # 3. Reputation accrues to researchers based on approved / disputed history, # so bounty sponsors can weight incoming claims by track record off-chain. # # Storage note: every record (bounty, claim, dispute, audit entry, researcher # profile) is stored as a JSON string inside a DynArray[str]. This keeps the # schema flexible (fields can be added without a storage migration) and avoids # nested container types, which GenVM's persisted-storage layer does not # support (only fully specialized DynArray[str] / TreeMap[str, str] and # primitives are allowed as contract fields). from genlayer import * import json import re BOUNTY_STATUSES = ("OPEN", "CLOSED") CLAIM_STATUSES = ("SUBMITTED", "ANALYZING", "APPROVED", "CHALLENGE_WINDOW", "DISPUTED", "REJECTED", "PAID", "VOID") SEVERITIES = ("NONE", "LOW", "MEDIUM", "HIGH", "CRITICAL") SEVERITY_RANK = {"NONE": 0, "LOW": 1, "MEDIUM": 2, "HIGH": 3, "CRITICAL": 4} DISPUTE_RULINGS = ("upheld", "overturned", "partially_overturned", "inconclusive") # Deterministic static-analysis indicators.
