Welcome

betonanything — self-service prize prediction platform. Dynamic pool mode DPM (share-based pool, odds auto-priced).

TCN Prediction Credits are non-exchangeable for any fiat currency or cryptocurrency (FD-003). Winnings remain in-platform only.

Getting Started — Register, Verify, Login

Account creation is email + password + OTP verification. New accounts receive 1,000,000 TCN and initial trust score after email verification.

Steps

Open /register, enter your email and a password (≥12 chars).
Submit — system sends a 6-digit OTP to your inbox (valid 10 minutes, single use).
Enter the code on /verify. After success, your wallet is credited.
Login via /login with the same email + password.
Sign out from Account → Sign out at the bottom of /me. Sessions are revoked server-side so a stolen cookie cannot be replayed.

If OTP expired or you mistyped it, just re-submit the same email on /register — a new OTP is sent (no error). Limit: 3 OTPs per email per hour.

Assets — TCN, Wallet, Trust

Your account holds three things: TCN balance (wallet), trust score, and contract history. None of these are convertible to real money.

TCN = platform credit. Initial gift = 1,000,000 TCN after email verification. Used to back bets and pay DPM share costs.
Wallet has two parts: available (freely usable) and locked (held in open contracts). Locked → available on contract resolution.
Trust score starts at a default value. It DECREASES on BREACH (you fail to honor a contract). It bounds your future bet/banker capacity.

DPM Markets — Dynamic Pool

DPM = Dynamic Parimutuel. Instead of fixed odds, you buy shares of an outcome. Cost rises as more shares are bought. Winners split the pool proportionally.

Create a DPM market

Go to /markets/new/dpm (or pick DPM from the new-market page).
Set title, category, lock-time, outcomes (N ≥ 2).
Set seed per outcome (initial shares = liquidity floor). Higher seed = lower initial cost-per-share but you pay more upfront.
κ (kappa) is admin-set and shown in the form. Tick risk-confirm and submit. Total seed cost is moved to locked.

Buy shares

Open a DPM market → outcome card shows current q (total shares). Drag slider for shares to buy → preview shows cost (rises with more shares). On settle, winning side gets: (total pool − κ fee) × your_shares / winning_total_shares.

Void & Refund

If oracle returns no clear winner or Σ outcome results ≠ 1 (programmable settlement rule), all bets are refunded at their original cost. No κ fee.

Example: DPM market “Who wins?” with 3 outcomes, seed=100 each. You buy 50 shares of A for ~52 TCN. Later total q_A=300, q_B=150, q_C=100. Pool=550 TCN. A wins → your payout ≈ (550 − fee) × 50 / 300 ≈ 87 TCN.

Settlement

Admin triggers settlement once the outcome is confirmed; all holders of the winning option are paid out proportionally (1 share = 1 TCN); the remainder is platform rake.

Account Page — Your Hub

/me/bets — current open DPM positions, with per-position max win/max loss.
/me/history — resolved contracts (with role, amount, status) and trust-score change events.
Scroll to the bottom of /me to find the red Sign out button. Logout revokes the session token server-side (cookie copy elsewhere cannot be replayed).

Transparency — Audit the Platform Yourself

Visit /transparency for the combined Merkle root computed over ledger / trust / contract / oracle_payload sources. The platform cannot retroactively alter history without invalidating the root.

Verify offline

Download fingerprint listings per source (BLAKE3, 32 bytes per row) — the page links to the verify script.
Run the verifier locally: it computes RFC 6962 Merkle root per source (leaf prefix 0x00, node prefix 0x01).
Combined root = BLAKE3(domain_tag ‖ ledger_root ‖ trust_root ‖ contract_root ‖ oracle_root). Compare to the value shown on /transparency. Match = platform consistent.

Entity signatures (Ed25519)

Every core entity (users / wallets / contracts / ledger entries) is signed by the platform Ed25519 private key over a BLAKE3 fingerprint of canonical fields. Browsers can verify each row independently with Web Crypto.

Entity	Fingerprint fields	Re-sign policy
`users`	id, email, role, status, trust_score, …	Yes (every save)
`wallets`	user_id, balance_available, balance_locked, version	Yes (every save)
`ledger_entries`	user_id, amount_delta, reason, ref_*, prev_hash	Append-only — never updated

How to verify in your browser

Fetch the row and the platform public key from /api/platform-pubkey.
Recompute the BLAKE3 fingerprint over canonical JSON of the listed fields.
Call Ed25519.verify(signature, fingerprint, publicKey) via Web Crypto. Mismatch = tamper.

Ledger: closed-loop accounting

Every wallet move is mirrored by an append-only ledger row signed in the same transaction (ADR-0030/0031). The sum of amount_delta for a user equals their net wallet.balance_available change.

reason	amount_delta	When written
`REGISTER_GIFT`	+1,000,000	sign-up gift on first email verification
`BET`	−stake / −cost	DPM shares purchased
`WIN`	+payout	Winning side at DPM oracle settle
`LOSS`	−liability	Losing side at DPM oracle settle
`REFUND`	+stake	Void & Refund: market VOIDED or dispute breach refunded
`ADMIN_ADJ`	±X	Admin credits TCN (2FA-gated)
`ADMIN_ROLLBACK`	±X	Admin reverses an erroneous entry (mirror amount)

Invariant: Σ amount_delta(user) = Δ wallet.balance_available(user) across the wallet's lifetime. Any mismatch indicates DB tampering — independently checkable from the row signatures.

Glossary

TCN: token. Not redeemable for any currency.
DPM: Dynamic Parimutuel — share-based pool with auto-priced odds.
overround δ: DPM house margin (Σ implied probabilities − 1). Locked admin-side per market.
κ (kappa): DPM settlement fee (1 − δ). Auto-derived; cannot be set independently.
BLAKE3 / Ed25519: BLAKE3 = fast cryptographic hash (32-byte digest). Ed25519 = elliptic-curve digital signature.
Merkle root: Binary tree of hashes; root commits to the entire dataset. Used for tamper-evident audit trails.
Void & Refund: Settlement outcome where all positions are refunded at original cost (oracle ambiguous or rule says no winner).
BET / WIN / LOSS / REFUND: Ledger entry reasons reflecting wallet net flow (see Ledger section).
fingerprint / signature: BLAKE3 fingerprint of canonical fields + Ed25519 signature by platform key. Browser-verifiable.
