The Sei Network has introduced its first public roadmap of key developments leading to the much-anticipated Giga Upgrade. This upgrade is designed to make the network one of the fastest layer-1 blockchains. The team has been clear that the upgrade is not a single event, but a progressive implementation to the live network.
The project published the Giga whitepaper earlier this month, which lays out the framework for the upgrade. Now, the development team is offering a timeline and a way for the community to track the mechanism.
Introducing The Giga Roadmap.
The first public roadmap of the milestones leading to the Giga Upgrade.
Implementing the Giga Upgrade to the live network is an extraordinarily complex engineering task.

In numbers, the development team aims to reach over 200,000 transactions per second and sub-400 millisecond finality. For context, prior throughput is roughly 5,000 to 12,500 TPS. If the upgrade is successful, it would represent a 50x jump.
One of the key features that has made this leap possible is a new multiproposer consensus protocol called Autobahn. This will allow many validators to propose blocks simultaneously, enabling hundreds of thousands of transactions per second.
Another change to come with the upgrade is the introduction of asynchronous execution. Instead of handling transactions one after another within a block, Sei will be able to process multiple transactions at the same time. By separating execution from the consensus process, the network can operate far more efficiently and reach throughput levels of up to 5 gigagases.
Sei Labs is also rolling out a redesigned EVM client. This allows the network to remain fully compatible with Ethereum’s developer tools and applications while delivering significantly higher performance. The current Sei mainnet already produces blocks in under 400 milliseconds under optimal conditions, making it considerably faster than Ethereum. With the Giga upgrade, that level of speed is expected to become the standard rather than an occasional peak.
The upgrade also tackles Miner Extractable Value (MEV), a big problem in blockchain where validators can reorder transactions for their own benefit. New safeguards are being introduced to help reduce this behavior and create a fairer experience for users.
In addition, Giga is being built with artificial intelligence applications in mind. Sei Labs believes AI-powered agents, automated trading systems, and other intelligent on-chain services will require infrastructure capable of handling massive transaction volumes, making high throughput a key part of the network’s future strategy.
At the time of writing, SEI is trading for $0.0661. Although the coin is down by 2%in the last 24 hours, it is up by 8% over the past week.
