- •
The Sei Giga Roadmap
The blockchain for trading
Develop internal closed devnet for Sei Giga.
- •
Build internal devnet
Successfully deploy geographically distributed devnet and stress test.

Push performance even further and share revised specification for Sei Giga.
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.
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.
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.
200,000
transactions per second
