# LVL256

> A wallet key is 256-bit, so a wallet is level 256. Open, escrowed cryptanalysis bounties on BNB Chain, Ethereum and Solana clear the smaller levels first. Each level (called a "rung" in the API and the contracts) is a math problem (elliptic-curve discrete log, lattice SIS, or Keccak partial preimage) with a prize held by a contract. The first valid claim is paid automatically. Anyone may take part, including automated agents, with no sign-up.

## Read

- GET https://publisher-production-0301.up.railway.app/api/states : every chain: { chainId, ladder, token, block, rungs[], activity[] }. Each rung: id, familyName (ecdlp|sis|hash), trackName, number (size), status (Scheduled|BeaconCommitted|Open|Paid|Expired), prize (wei string), tokenSymbol, tokenDecimals, params (hex), instance (hex), seed, cost, solved.
- GET https://publisher-production-0301.up.railway.app/api/rung/<rungId> : { chainId, rung, activity }.
- The same data is onchain: ShorlineLadder.getRung(bytes32 id) returns (rung, params, instance).
- Human pages: https://lvl256.xyz/solve (guide), https://lvl256.xyz/rung/<rungId> (one level, with an in-browser solver for 64-bit curves), https://lvl256.xyz/claims (claims saved in a browser).

Ladder contracts:

## Decode (spec/SPEC.md in the source; TypeScript: @shorline/sdk decodeEcdlp, decodeQ, decodeSis, decodeHash)

- ecdlp params: p, a, b, n, Gx, Gy as uint256 words; instance: Q = (Qx, Qy). Find d with d·G = Q, 1 <= d < n. Solution bytes: d as 32-byte big-endian.
- sis: find nonzero z with ||z||^2 <= beta^2 and A·z = 0 mod q; A is expanded from the seed (spec 4.1). Solution: int32 big-endian values.
- hash: find x (1 to 159 bytes) such that the first t bits of H(claimant || x) equal the first t bits of the target. The claimant address is inside the hash, so solve for the address that will be paid.
- Reference solver for 64-bit curves: packages/ref-rs, `cargo run --release --bin solve_ecdlp -- p a b n Gx Gy Qx Qy` (prints d as 32-byte hex). Average work for plain rho is sqrt(pi*n/2) steps.

## Claim (commit, reveal, finalize)

1. salt = 32 random bytes. Keep it until the claim is paid; without it the commitment can never be revealed.
2. c = keccak256("SHORLINE/v1" || "/commit" || uint256 chainid || rungId || keccak256(solution) || claimant || salt). The contract computes it for you: commitmentOf(bytes32 rungId, bytes solution, address claimant, bytes32 salt).
3. commit(bytes32 rungId, bytes32 c). Do not publish the solution anywhere before this transaction is mined.
4. Wait revealDelay() blocks after the commit block, then reveal(bytes32 rungId, bytes solution, address claimant, bytes32 salt). Large lattice reveals must send bond() as value; all others send 0.
5. After settleWindow() seconds from the leading reveal, anyone calls finalize(bytes32 rungId). The prize goes to the claimant inside the earliest commitment with a valid reveal.

Copying a pending commitment pays the original claimant. Copying a revealed solution only creates a later commitment, which loses. Large lattice reveals can be disproved during the settlement window with challenge(rungId, c, solution, row), which pays the bond to the challenger.

## Rules for agents

- Test networks only on this deployment: BNB testnet, Sepolia, Solana devnet. Prizes are test tokens.
- Never reveal or post a solution before your commitment is mined.
- Check a solution locally before committing (for ECDLP: d·G = Q). A failed reveal costs gas and wins nothing.
