Co-founder & CEO of Mysten Labs - building a decentralized internet @SuiNetwork @WalrusProtocol. Before: Wrote SW that runs on every single one of your devices
Your AI agent's memory is probably stuck inside one app.
Walrus Memory (@WalrusProtocol) fixes that with an MCP that creates memories as you chat, then can recall them anywhere - Claude Code, Pi, etc.
Portable and actually owned by you!
ICYMI: Paga took the stage at Sui Live Miami.
@paga processed $11B in payments and 169M transactions in 2025, and now it's bringing that scale to Sui with $USDsui integration for instant, direct, dollar-denominated settlement across Africa.
Watch the full moment below 👇
Compliant with major global regulatory frameworks, like MiCA, FATF, and Basel. Settling point-to-point in real-time.
This is institutional-grade cross-border payments, built on the network designed for it.

Institutions don't need stablecoins to work around them. They need stablecoins that work inside them.
@RemiTechnology is launching exactly that. Introducing the first bank-issued, regulated stablecoin infrastructure on Sui for licensed financial institutions worldwide.
After today’s Anthropic news, decentralized AI memory feels more important than ever. We may be witnessing a pivotal moment in human history, one that will shape who controls artificial intelligence and how it is accessed for generations to come.

Join me on a live 1M+ Sui tps experiment via tunnels. Apply here, you just need a laptop and a camera to record and share your screen. Leave the rest to me…
We are not slowing down. Today, confidential transfer is going live on Sui Devnet.
Sui is not your grandpa's blockchain. It's a coordination layer, settlement layer, a programmable platform where all the tools you need to create/exchange/manage assets of value. Confidential transfers is the latest building block added to the stack. A lot more to come.
Confidential transfers are live in public beta on Sui Devnet.
Transfer amounts and balances are private, with controlled visibility for compliance and auditability.
What this means for finance workflows: 🧵

How did @b1ackd0g find @kostascrypto and bring him to @Meta to work on project Libra and eventually create @SuiNetwork
This is that story from Kostas's perspective,
and how Sui got a real edge over other L1s in terms of post-quantum security.
I'm one of the people most directly responsible for this outage. I take Sui outages extremely personally and am incredibly disappointed that this happened.
I'll echo what @EvanWeb3 said: Moving fast is no excuse for outages. This outage was caused primarily by an edge case in gas smashing introduced by address balances. However, we did not ship this feature carelessly. We spent over 6 months testing address balances and tried as hard as we could to exercise every edge case and combination of features we could think of. Unfortunately, we were bitten by an edge case that we did not discover during testing.
Again, this is not an excuse - it shows that our testing strategy was inadequate, despite how much effort we put into it. We did not have a systematic way to enumerate or discover all possible edge cases. We will be re-examining our approach in light of this. But I do want to emphasize that we did not ship this feature carelessly or in a rush. We made mistakes, but we were absolutely not operating in "move fast and break things" mode.
One more thing: Address Balances is by far the biggest change to Sui's execution model that we have shipped, and we don't have any plans to ship anything this large and disruptive again. It was a necessary change to make Sui into what it should be, but we don't seek out huge disruptive changes like this for the sake of it.
Now that the feature is out we will be redoubling our efforts to make Sui the most reliable L1. We have a lot of work to do, I'm excited to start on it!
Moving fast is not a valid excuse for the outages. They are unacceptable, period. You have my sincerest apologies for the outages.
We are focused on restoring the level of reliability and security to the absolute maximum.

Any crypto OG can tell their horror stories of running out gas when they have to make a crypto transfer
We have come a long way
This eliminates one of the biggest pain points for app integrations. Sometimes the biggest unlocks are the most obvious in hindsight. Well done
