THE STORY SO FAR

HOW IT WORKS

Proof of History

A verifiable delay function creates a cryptographic clock. Validators agree on time before they agree on order, which lets the network skip a lot of consensus chatter.

Tower BFT

A PBFT-style consensus that uses PoH as its source of truth. Votes are timestamped and replayed, so finality is fast and cheap.

Turbine

Block propagation borrowed from BitTorrent. Leaders shred blocks into small packets and gossip them through tiered neighborhoods of validators.

Sealevel

Parallel smart-contract runtime. Transactions that don't touch the same state run at the same time across many cores, which is why throughput scales with hardware.
