The Sei Giga Roadmap

Define the initial specifications of Sei Giga.

• •

  Draft v1 whitepaper

  Produce and publish the first version of the Giga Whitepaper.

• •

  Defining MEV in Giga

  Formalize the MEV vectors the protocol must eliminate.

  Read more↱

Develop internal closed devnet for Sei Giga.

• •

  Build internal devnet

  Successfully deploy geographically distributed devnet and stress test.

Replace merkle trees and split hot from cold state to eliminate the write-amplification ceiling.

• •

  Live State Reimagining

  Swap merkle trees for a flat key-value store with lattice hashes - an order of magnitude of headroom.

• •

  Scale Historical State

  Embedded DB for hot live state; horizontally scalable storage for the cold archive.

• •

  Domain-Optimized Storage

  Purpose-built engines (Parquet+DuckDB, LittDB) for receipts, logs, blocks, and transactions.

Rebuild Sei's execution client to hit Giga-scale throughput on the existing consensus.

• •

  Pipeline Execution

  Stage parsing, validation, and signature checks ahead of execution to keep executors hot.

• •

  Reduce Critical-path Execution

  Move receipts, logs, and indexing off the commit path into async pipelines.

• •

  Improve Runtime/VM Efficiency

  Tighten cache locality and cut allocation churn for stable throughput under mixed workloads.

• •

  Deploy Execution Client to Mainnet

  Ship the rebuilt client live - v2 throughput today, ready for consensus next.

Pre-Giga network consolidation: strip legacy code so the path to Giga is clean.

• •

  Implement SIP-3

  Deprecate Cosmos and CosmWasm so the network can scale on a streamlined EVM-only stack.

Stand up Autobahn consensus on testnet, enabling multi-proposer, order-first, asynchronous state, with 200,000 TPS and 400ms finality.

• •

  Consensus Whitepaper

  Publish the final spec covering Autobahn's multi-proposer model in full.

• •

  Autobahn order-first

  Finalize transaction ordering before execution so ordering doesn't wait on variable runtime.

• •

  Asynchronous State Consensus

  Let later blocks assert earlier state commitments so ordering doesn't stall on state agreement.

• •

  Operational Reconciliation

  Detect and reconcile missing or delayed assertions without breaking deterministic replay.

Upgrade the live Sei Network to Autobahn consensus.

Introduce private mempool to Sei Network via the Sedna protocol.

• •

  Encrypted Mempool Research

  Survey and pressure-test the cryptographic primitives for private dissemination.

• •

  Private Mempool Design

  Specify how transaction fragments spread across lanes and reassemble only after ordering.

Deploy testnet for Hermes consensus (whitepaper forthcoming).

Merge Hermes testnet into Sei mainnet.
