The architecture of digital finance is being written right now, in different forms across different regions.

Where it converges is where the interesting questions are. Looking forward to speaking at UHY EMEA in Athens, on June 19.

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.

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!

@xMoneyGreg talking about digital payments and infra can’t be missed.

If you happen to be around at Panathēnea join the @SuiNetwork side event.

[Greg Siourounis @xMoneyGreg]

Stablecoin payment volumes surpassed PayPal and remittance corridors in 2025.

The infrastructure question has moved from theoretical to operational: which infrastructure can carry that volume under MiCA-grade compliance.

Discussing more about this at the @SuiNetwork side event during Panathēnea 2026. May 28, SuiHub, Athens.
