Whitehat researchers submit bonded vulnerability # reports carrying an executable PoC trace (reproduction calldata). Every # call into the target must use a selector of the verified ABI, and each # report is deduplicated by a semantic fingerprint of its execution path # (keccak256 over the ordered (address, selector) pairs), so rewording a # known finding cannot earn a second payout. GenVM validator consensus then # fetches the pinned policy, judges the PoC against a deterministic calldata # disassembly (selectors, ABI words, resolved signatures) and the list of # already-validated paths, and cross-examines the claimed severity with an # LLM under a custom equivalence validator. A validated report locks its bounty and enters an immutable # challenge window; the only way the project can stop the payout is a bonded # rebuttal that is cryptographically bound to the exact PoC and that survives # the same consensus. After the window lapses anyone can settle the report. # # Nobody holds a discretionary key over payouts. The governor role can only # LENGTHEN protocol windows (never shorten them, never touch an in-flight # report) and sweep protocol fees that are already booked to the treasury. # # Accounting model. Every GEN the contract holds sits in exactly one bucket: # # total_vault_reserves sum over programs of (available + locked) # total_bonded_researcher researcher bonds held on open reports # total_bonded_project project challenge bonds held on open reports # total_claimable credited, not yet withdrawn (pull pattern) # treasury_fees protocol fees and slashed researcher bonds # # and the conservation identity # # sum(buckets) == total_inflows - total_outflows # # is re-checked at the end of every state mutation (ERR_INVARIANT_VIOLATION # otherwise). total_inflows counts every gl.message.value the contract has # accepted and total_outflows every emit_transfer it has queued, so the # identity is the contract balance equation stated over the native flows the # contract itself controls. get_solvency() compares it to self.balance. import hashlib import json from dataclasses import dataclass from datetime import datetime, timezone import genlayer as gl from genlayer import Address, u256 from genlayer.storage import TreeMap # genvm-lint matches storage dataclasses on the bare name `allow_storage`. allow_storage = gl.storage.allow # --- Units and protocol constants -------------------------------------------- ATTO = 10**18 BPS = 10_000 MIN_PROGRAM_DEPOSIT = 5 * ATTO MIN_RESEARCHER_BOND = 1 * ATTO CHALLENGE_BOND = 2 * ATTO DAY = 86_400 DEFAULT_CHALLENGE_WINDOW = 7 * DAY MAX_CHALLENGE_WINDOW = 30 * DAY DEFAULT_CLOSURE_NOTICE = 14 * DAY MAX_CLOSURE_NOTICE = 90 * DAY PROTOCOL_FEE_BPS = 250 # Severity ladder and the share of the program's AVAILABLE vault a validated # report locks at that tier.
