Institutional trading today runs through centralized exchanges and OTC desks.
Onchain venues haven't been able to match the pre-execution privacy or execution guarantees those desks can offer.
Giga will close this gap.
1/ SHx bridge is now live on @solana.
This marks the next step in Stronghold's multi-chain strategy, built on the interoperability foundation established through the Stellar-Ethereum bridge and @axelar.
Model Context Protocol gives an AI agent hands; Agent Skills give it knowledge. Hedera now offers both.

Four Chains. One Foundation.
Here is the latest SHx ecosystem update from our CTO @ItsSeanBennett as we continue expanding across key blockchain networks.

1/ Announcing Ethereum Institutional
An independent non-profit dedicated to accelerating the institutional adoption of Ethereum, its L2s, applications and overall ecosystem.
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
AI agents can now trade tokenized stocks.
Starting today, more than 40,000 @virtuals_io AI agents can now trade 430+ Ondo tokenized stocks through @treasures_io.
Algorithmic trading already dominates equity markets, but real execution edge has stayed mostly with institutions. That advantage is now extending to autonomous agents with Ondo tokenized stocks.
Traders can now leverage:
→ Agent hedge funds
→ Copy-trade vaults
→ Autonomous portfolios
→ 24/7 programmatic trading
The world's largest market is opening to its newest class of autonomous participants, powered by Ondo.
Giga and Sedna have been leading the conversation.
Everything else across Sei — @MonacoTrading's trading toolkit, positive bridge flows, and more — @TokenRelations tracks independently, every week.
Everyone keeps saying this with total confidence, like it's a foregone conclusion.
To me, this point of view is both short-sighted and myopic. It's failing to grasp the technology being built, the problems being solved, and the true value being created.
It also does not allow a long enough time horizon for markets to properly digest and value the assets.
Equating a foundational layer-1 cryptographic network to a simple cash-flow business misses the forest for the trees on a galactic scale.
A token buyback program is a microeconomic tool for capital allocation in a centralized corporation. A decentralized protocol is a macroeconomic environment. These are public utilities providing global trust, security, and computational fuel for a whole decentralized internet.
I do not believe that the native assets of these ecosystems will be demonetized quickly by less ambitious and less valuable assets that have found a narrow window of market opportunity through which they can turn a quick profit. Those assets will struggle to retain their value because competition and market reactions will make it ever more challenging to defend their profit.
Rather, the more likely outcome is that value accrues to the assets that have a large macroeconomically differentiating use case. This will happen gradually over time as the market begins to migrate away from antiquated legacy systems and towards these improved trustless ones.
A lemonade stand or a corporation can go bankrupt, change its behavior maliciously, or mismanage its operations. A genuinely decentralized or highly secure distributed ledger provides a tamper-proof, uptime-guaranteed, public utility.
These are not the same. They are not valued the same. They are not offering the market the same proposition.
So to sum up. I hear this kind of take so often these days, and I think it's near-sighted and too narrow to see what's really happening and the true value of digital assets.
You have to take a longer view.
You have to think bigger.
You have to believe in somETHing.

Last week we started talking about privacy on @SeiNetwork.
This will come to Sei via a private transaction layer called Sedna.
Sedna will give roughly 90% of the benefits of privacy but takes 0.01% or less of the work a full ZK layer would take.
Privacy is relevant in two domains: pre-execution and post-execution.
Pre-execution privacy means simply that a transaction is private up until the point of finality, where it can't be reverted.
This is the domain where privacy matters most.
By having transactions public pre-execution, users are exposed to a whole world of risk that makes using a blockchain unfavorable.
In some ways this is the original sin of of crypto. All MEV stems from this. Public transactions can be frontrun, backrun or sandwich attacked by other users. They can also be reordered or outright excluded by validators.
This happens on layer 1 blockchains all the time and largely the space has come to accept it.
I don't, and I believe the space has set itself back by years in accepting the rampant levels of MEV we see today.
Financial transactions need to be predictable. For retail and institutions to use blockchains, those chains need to be predictable.
With Sedna, Giga will have this. Presently @Sei_Labs is finalizing v2 of the Giga whitepaper, which explains the interaction between Giga and Sedna, and more.
Privacy is coming to Sei.
Multi-proposer consensus, like Sei Giga's Autobahn, provides massive gains in throughput and speed.
The tradeoff: increased spam via duplicate transactions.
Sedna, an upcoming protocol from @Sei_Labs, removes spam while bringing privacy and MEV resistance to Giga.
