Every Block.
Every Number.
Sourced.

Orders transactions and signs each Verity block, as often as every 250 ms (up to 1 MiB and 4,096 transactions). Non-conflicting transactions run in parallel with results identical to serial execution, and every block is re-executed serially before its batch is committed to Solana. This is a single sequencer, not a validator set.

Batches publish their payloads for deterministic re-derivation. Until a batch confirms, anyone can demand its bytes on Solana; data withheld past the deadline rejects its commitment.

Any party can dispute a posted state commitment during its challenge window. A bisection game on Solana narrows the dispute to one instruction and settles it on-chain. A block is final only once its batch is confirmed.
