Sui Announces Successful Deployment of Mysticeti on Mainnet, Cutting Consensus Latency to 390 Milliseconds

Sui’s latest Mysticeti protocol significantly reduces consensus latency to just 390 ms, showcasing its exceptional technology and developer stack.

Sui, the groundbreaking Layer 1 blockchain, has recently deployed Mysticeti on Sui Mainnet following a successful trial on Testnet. This groundbreaking protocol significantly reduces consensus latency to an impressive 390 milliseconds, solidifying Sui’s position as the leading consensus layer in the industry.

Based on thorough research on Byzantine fault tolerance (BFT) consensus mechanisms, Mysticeti is a major improvement over Narwhal-Bullshark, the consensus algorithms introduced with Sui Mainnet over a year ago. Mysticeti achieves remarkable transaction speeds, expanding Sui’s already impressive low latency performance to encompass all transaction types on the network.

“Mysticeti’s successful deployment is a testament to the collaboration between research and engineering, and the validator community that has integrated this new consensus mechanism,” said Dmitri Perelman, Head of Engineering at Mysten Labs. “Mysticeti is a next-generation consensus protocol that sets a new standard for blockchain transaction speeds and puts Sui at the forefront of our industry.”

Sui’s object-oriented architecture enables the network to handle transactions in a unique manner, taking into account the specific attributes of the transaction and the objects it involves. Transactions on Sui involving only “owned objects,” such as peer-to-peer transfers, can bypass the need for consensus and follow a fast-path execution that completes more quickly. With Mysticeti, transactions involving shared objects, like those in marketplaces or collaborative game assets, are processed using an optimized version of BFT consensus. This leads to significantly lower latencies, almost comparable to owned object transactions. Mysticeti optimizes cross-validator communication and maximizes network bandwidth to ensure efficient data transfer.

Having been on Testnet for the past three months, Mysticeti has achieved impressive results, such as an 80% reduction in latency. This has created a lot of excitement among Sui’s developer community, who are eager to see the update rolled out on Mainnet. Now that the update is live, the Sui Network has the capability to process tens of thousands of transactions per second, with impressively low end-to-end latencies of less than one second.

Kevin Nelson, Co-Founder & CTO of Aftermath Finance, which created a leading DeFi protocol on the network said, “Mysticeti’s shift to minimizing latency for the general case—shared object transactions—marks a significant advancement across many sectors on Sui, particularly within the Sui DeFi ecosystem. The rollout to Mainnet has already begun to show tangible results, with noticeable latency reductions across our entire product suite. At Aftermath, we are excited to leverage Mysticeti’s full capabilities to deliver more efficient, lower latency products to market.”
