Introducing Sovereign SDK -- the first rollup framework that executes 99% of transactions under 10 ms, fast enough to bring price discovery fully onchain.
Now even solo devs can build efficient, global financial apps.
Production-ready today.
Go build the next Hyperliquid.

So I'm convinced that inclusion latency can be independent of validator count and geographic distribution using MCP.
BUT an inclusion guarantee still seems significantly weaker than the *execution* guarantee you can get from a single sequencer/proposer.
Here's what I mean:
Essentially in MCP you can only get an inclusion guarantee, meaning your tx will be in the block, but not a guarantee that your transaction will actually get executed bc there could be a conflicting tx the was confirmed by another proposer in the same slot. That conflict has to be resolved and might end up making your tx invalid.
Whereas with a single sequencer or leader, the sequencer can give you not just a guarantee of inclusion in the block, but a guarantee that your transaction will be executed and result in what you want. It can do this bc it sees and orders all txs globally.
Let's say you're trading on a CLOB and you send in a order to lift a bid. An MCP proposer can only tell you "yep you're in the block". A single sequencer/proposer can tell you "yep you're in the block AND your trade will be executed".
This execution guarantee is a lot more powerful than an inclusion guarantee, and is seems you can't get it with MCP.

Last month we landed a host of new optimizations for NOMT to save disk space and improve performance.
Here's a benchmark with 1B accounts, with transfers to freshly created accounts.
Previous TPS: 19k
New TPS: 34k
Previous space usage: >1TB
Current space usage: 140GB

My old Twitter (@ventali_) and Telegram were hacked. The attacker is impersonating me to target tech and crypto founders & investors with phishing links — even using deepfakes of me on Zoom. >50 people were contacted. Some nearly clicked.
I filed 10 reports to @X and haven't heard back. I called the SF police and filed an FBI IC3 report.
Please don’t click any links from the attackers.
I only use:
Twitter → @_ventali
Telegram → @ventalitan

RISC Zero is doing such good work here, that I’m probably more worried about a Rust std library or LLVM bug than about soundness of their circuit. Unfortunately, that still leaves a lot of room for worry!
Compiler bugs are common, and 32-bit RISC-V is a pretty niche target.

Is it hard? Yes
Our soundness bugs devastating? Yes
Are we closer than you might think? Yes
From Day 1, yes the same day we released our proof system, @RiscZero began the long process of formally verifying our zkVM.
Recently we launched "Picus" which mathmatically proves determinism in our circuits during CI! This is the cause of 96% of soundness bugs in ZK systems (Per ZK-Security).
This effort plus some more we are working on, shows we can get to a provably sound RISC-V zkVM faster than you most think.

I wanted to learn about @celestia interop, so I had @nickwh8te and @prestonevans__ teach me!
Celestia is definitely learning from Ethereum's mistakes and taking an alternative approach to the Rollup Centric Roadmap
Glad we have multiple attempts at the same design!
