I spent last weekend reading the new #MEV research from @Sei_Labs, and it completely resets how I think about L1 design.
MEV has already stripped more than $1.3B from Ethereum users, and #SEI GIGA is a good one to fix it.🧵
1/ To understand why #SEI’s approach is different, we need to look at where MEV actually appears.
MEV bots scan it, detect profitable opportunities, inject frontrun/backrun bundles, and manipulate ordering.
A single proposer then builds the block, reorders transactions, sandwiches, or steals value.
MEV gets extracted, and the user loses money.
#Sei Giga flips the old model with #MCP (Multiple Concurrent Proposers).
Instead of one proposer controlling the entire block, several proposers publish blocks in the same tick.
Here’s what that looks like in practice:
User transactions flow to
→ proposer A, Proposer B, Proposer C
→ each proposer builds its own block (Block A, Block B, Block C)
→ SEI Giga’s consensus merges them into a single final chain.
A parallel block pipeline replaces the single choke point that created classic MEV.
MCP introduces new MEV dynamics, tx stealing, proposer timing games, proposer-to-proposer auctions.
here’s the breakthrough:
Sei Labs formalized them and showed they are bounded.
Predictable MEV is fundamentally safer for users and markets.
Bounded MEV is exactly what high-volume systems need: perps, options, RWAs, credit markets, arbitrage engines.
You can’t build real financial infrastructure on top of unbounded extraction.
If Sei succeeds, the beneficiaries are the traders, the liquidity providers, and every user who interacts with real onchain markets.
MEV becomes contained instead of weaponized.
Market moves faster on $SEI. ($/acc)
