Episode notes
APIs Lose To Multicast Fiber For Trading Speed
- APIs are too slow because they rely on unicast over the public internet, creating propagation delays that matter to traders.
- Austin Federa contrasted public internet unicast delays with DoubleZero's private multicast fiber to show why speed advantage matters.
Shreds Provide Sub Block Alpha For Traders
- Shreds are not finalized state but provide alpha to traders by surfacing sub-block information roughly every 10ms.
- Validators simply send the same data they'd send to Turbine but copy it into 00 so traders see raw decoded market events faster.
Combine Venue Feeds And Shreds To Improve AMM Pricing
- Use fast external venue feeds plus on-chain Solana shreds to inform pricing for Prop AMMs and market makers.
- Austin Federa recommended combining decoded off-chain venue streams with recent on-chain transactions to set intra-block quotes.
