How Bluefin works, end to end.
Bluefin is a decentralized prediction market for World Cup 2026. You buy YES or NO shares in real match outcomes; when a verified result lands on-chain, winning positions settle automatically. Under the hood, every price, result, and payout traces back to two things: real-time data from TxODDS' TxLINE network, and trustless settlement on Solana.
From fixture to payout
Every World Cup 2026 fixture becomes a set of markets — match result, total goals, scorers. Markets are created automatically from the TxLINE fixtures feed.
Buy YES or NO at a quoted multiplier. Odds are derived from TxLINE StablePrice data in real time; your stake and quote are locked into an on-chain escrow the moment you confirm.
When the final whistle blows, the result arrives on the TxLINE scores stream. Bluefin fetches a Merkle proof for the result and verifies it against TxODDS' on-chain validation account.
The settlement instruction lands on Solana with the proof root attached. Winning positions become claimable directly from escrow — no middlemen, no claims process.
The TxLINE connection
TxLINE is TxODDS' cryptographically verifiable sports data network. It is Bluefin's single source of truth: fixtures define the markets, StablePrice odds drive the quotes, and Merkle-proven score data decides every settlement. Bluefin is a launch integration built for the TxODDS Prediction Markets & Settlement track.
Bluefin's backend opens a guest session with TxLINE, subscribes on-chain on Solana, signs an activation message with the same wallet, and receives an API token. Every data request Bluefin makes is tied to that verifiable on-chain subscription.
Scores and odds arrive over Server-Sent Events streams — the same push channel Bluefin relays to your browser. When a goal is scored, the market moves within seconds, not minutes.
TxODDS batches every score update into Merkle trees and anchors the roots on Solana. Bluefin never settles a market on an unproven result: it fetches the proof for the exact statistic, and the settlement transaction carries that root on-chain.
Because TxODDS publishes validation accounts on Solana, anyone — not just Bluefin — can re-verify the data behind any settlement. The proof viewer on the Stats & Proofs page shows exactly this.
