Nasdaq Puts Proprietary Market Data Onchain via Pyth Network
Nasdaq is piping its TotalView market data onto the blockchain through Pyth's marketplace, opening real-time data to DeFi apps.
Nasdaq just made a move that should have every DeFi developer paying attention. The exchange giant is partnering with Pyth Network to bring its proprietary TotalView market data onchain — and that's a big deal for anyone building financial applications on blockchain infrastructure.
TotalView is Nasdaq's deepest level of market data, covering full order book depth across Nasdaq-listed securities.

That's a vote of confidence in the staying power of on-chain finance, and it puts pressure on other legacy data providers to follow suit or get left behind. The line between TradFi data and DeFi execution is getting thinner by the quarter.
