Bulk Perps: The Sidecar Thesis

Sam argues Solana's perps problem runs deeper than liquidity—the chain lacks execution guarantees market makers need for tight quotes, while Hyperliquid processes 5-10x Solana's entire perp volume. Bulk's answer is a validator-native sidecar network handling matching and risk separately from Solana's leader-based execution, paired with a SPAN-style portfolio-aware risk engine that cuts margin requirements 70%+ on hedged books—the institutional standard CME has used for decades but no live crypto venue currently offers. The model preserves composability by keeping collateral productive on Solana while supporting trades, with mainnet targeting this half.

Solana Perps: Engineering the Missing Piece

Solana hosts crypto's deepest retail user base but has ceded perpetual futures dominance to Hyperliquid, which runs 5 to 10x the volume of Solana's entire perps complex. Sam Schubert attributes this to Solana's general-purpose design lacking the execution guarantees perp makers need—non-deterministic ordering, opaque fees, and rotating validator leaders every 1.6 seconds make quoting impractical. Three new protocols (Phoenix Perps, Bulk, Bullet) are attacking the execution gap with different approaches, but closing that gap may not matter if Solana can't convert its memecoin-focused retail base into active perps traders.
