Next generation blockchains like Sei Giga will create types of MEV that are completely new, and poorly understood. Today, we share the first ever paper exploring MEV in next-generation blockchains. With this we can protect users from this MEV, before they can be affected.

The Giga upgrade will make Sei Network the first blockchain supporting Multiple-Concurrent Proposers or MCP. All current blockchains are single proposer, which limits their throughput. Giga will push the boundaries of blockchain design, unlocking never before seen performance.

MCP in particular will introduce entirely new categories of MEV. In a new research paper from Sei Labs, we explore and identify the new types of MEV emerging from MCP blockchains, for the very first time.

Traditional MEV largely consists of censorship, sandwich attacks, backrunning and frontrunning, although other forms of MEV also exist. MCP blockchains will see new types emerging, such as tx stealing, proposer to proposer auctions and timing races.

Our existing research leaves many open questions, but makes one thing clear: The new types of MEV produced by MCP blockchains are not unbounded. Rather, these types of MEV fall into a domain the protocol can control.

In future publications Sei Labs will further explore this MEV, and begin to propose solutions to limit them. Read more on Arxiv:
