@Sei_Labs has published benchmark results for Hermes, the consensus protocol it plans to run on @SeiNetwork's Sei Giga. In a controlled test across 51 validators at 100,000 transactions per second, Hermes recorded a median finality of 68 milliseconds. Even when three block-proposing validators were stalled, the protocol finalized 95% of transactions within 206ms, finishing ahead of three rival designs in the team's own internal comparison.
Fault tolerance is the central problem Hermes is designed to address. Most consensus protocols slow down or stall when validators go offline. The Hermes results suggest the protocol can absorb validator failures without a significant collapse in confirmation speed, which matters most in high-stakes trading environments where every millisecond counts.
Hermes sits within a broader, multi-phase engineering program Sei Labs calls Sei Giga. Sei Giga is not a single upgrade; it is a multi-phase engineering program that rebuilds Sei's execution client, storage layer, and consensus mechanism from scratch. The design goal is to allow for efficient, fast, and fair on-chain trading, which requires very high throughput, low latency, and the ability to bound censorship and MEV risk.
Hermes is a later-stage addition to the Giga stack. The current roadmap calls for deploying a testnet for Hermes consensus before merging it into Sei mainnet. The protocol's full whitepaper has not yet been published. Hermes is listed as a next-generation consensus protocol on the official roadmap, with its whitepaper still pending.
The Giga program has already set ambitious top-level targets. The layer-1 blockchain is targeting over 200,000 transactions per second and sub-400 millisecond finality, numbers that would make it one of the fastest EVM-compatible chains in existence. Sei's updated Giga Whitepaper v2 reduced the targeted finality to below 250 milliseconds, down from the previously stated 400 milliseconds. The 68ms figure from the Hermes lab results, if it holds in a live environment, would represent a meaningful step beyond even those revised targets.
As with any benchmark published by the team developing the protocol, the results carry caveats. Real-world mainnet performance after any upgrade may differ from devnet benchmarks. Live networks carry economic activity, validator diversity, and unpredictable transaction patterns. Sei Labs has not yet set a hard launch date for Hermes on mainnet.
