Design

Blink is a verifiable, crypto-native spot and perpetual exchange.

Transactions are timestamped and sequenced by DoubleZero contributors and broadcast to all traders.

The system is designed to allow traders to verify orders and build orderbooks independently at ultra low-latency from the raw sequenced transaction feed, without requiring trust in any intermediate components.

The matching-engine executes the sequenced transactions and posts the transaction log to the data availability layer. The events feed from executed orders is broadcast to traders and available over RPC.

The settlement-engine generates the ZK proofs and settles trades on Solana L1 for trade finality.
