A whitepaper on a Multi-Proposer protocol for Monad just went up on Arxiv, authored by @Category_Labs. Two scoops:
1. Monad is pursuing Multi-Proposer consensus. This will be their next big public narrative.
2. Like Solana, they're following Sei's decision to go multi-proposer.
Sub-250ms finality. Pre-execution privacy. Institutional-grade predictability.
The Giga Whitepaper V2 laid out the most performant trading infrastructure yet.
Here's what else went down this week ↓

Markets Move Faster on Sei. ($/acc)
BREAKING: Tokenized stocks hit a record $1.8 billion market cap, with Ondo holding about 58% of on-chain value.
xStocks holds roughly 37% but leads on holders and total volume; Binance’s bStocks took 6% within eight days of launching.
$SEI just confirmed faster than a human blink and 8 times faster than Visa
Giga V2 just dropped and here’s what that actually means. your transaction confirms in under 250 milliseconds - a blink takes 300ms, so it’s done before your eyes even close. Visa takes 1 to 2 seconds.
Sei is faster. 200,000 transactions per second is the target - most blockchains do a few thousand on a good day. they also scramble your transaction into fragments across validators before it executes so nobody can see your trade and frontrun it. and MEV - basically validators stealing value by reordering your transactions - is built into the protocol to resist, not fixed with some third party patch.
if you’ve ever had a trade get frontrun or paid stupid gas fees because of congestion, this is the upgrade that’s supposed to fix all of that. @SeiNetwork keeps saying it’s built for trading.
hard to argue with this
BREAKING: Sei Giga is targeting institutional-grade onchain execution.
Messari says Sei has ~$308M in tokenized RWAs from Ondo, Apollo, Libre and GAIB, making up ~72% of network TVL.
The difference between 400ms and 250ms is almost imperceptible to the human eye.
To a trader, it's 37.5% less time for the market to move between your order and your fill.
Giga Whitepaper V2: sub-250ms finality.
V2 of the Sei Giga Whitepaper is live.
Sei Labs can now confirm that Giga will have substantially better performance and an improved featureset over what was initially described.
Giga will have:
- Sub-250ms finality
- Pre-execution privacy
- Protocol-level MEV resistance.
Here's what's new and why it matters:
Finality: sub-250ms, down from 400ms.
Autobahn's pipelined two-phase BFT is designed to reach consensus in 1.5 round trips versus Tendermint's 3.
In the design, ordering finality is decoupled from state attestation: every trade will settle at consensus speed, while execution happens asynchronously so heavy computation never delays block production.
State commitments will use lattice hash divergence digests over write logs, eliminating Merkle tree computation from the hot path.
The biggest addition in this new version is Sedna.
On single-leader chains, the block producer controls ordering. On multi-proposer chains, any proposer that sees your full transaction can duplicate it and race you in the merge order. The whitepaper identifies three MCP-specific MEV channels.
Sedna is designed to address all of them. Senders would encode transactions into rateless fragments distributed across proposer lanes, and no proposer would see the full payload until the finalization threshold is crossed.
Pre-execution privacy without encrypted mempools, threshold decryption or adding latency to the critical path.
Under Giga, transaction ordering will be fully deterministic.
The tip priority merge rule orders lanes by descending maximum tip, preserves intra-lane position, and deduplicates by hash. The output is a pure function of the committed cut.
Every correct executor will derive the same ordered transaction sequence from the same finalized data.
Storage and execution were also substantially upgraded in v2.
Storage: flat LSM-based key-value store will replace Merkle Patricia Tries. Tiered hot/warm/cold architecture. Divergence commitments over write logs introduced.
Execution: Block-STM parallel execution with optimistic concurrency control. Pipelined parsing, address recovery, and signature verification.
The paper also clearly defines:
- Production Sedna with PIVOT-K incentive layer
- Autobahn consensus upgrades
Forthcoming research:
- Full transaction fee mechanism
- Full-scale PQC alternatives beyond ML-DSA
- Giga tokenomics
Introducing the Giga Whitepaper V2.
The first Giga Whitepaper laid out the fastest blockchain yet.
V2 brings privacy, predictability, & performance.

BREAKING: Two people have climbed to the top of the Empire State Building in New York City, holding a banner from the skyscraper's antenna reading, "When the power of love beats the love of power, the world knows peace."
As of now it's unclear how the pair reached the top of the building as police work to get them down from the spire, 1,454 feet above the ground.
