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. 🙏 Walrus Memory

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.
This is how sui was born and we won't stop until we make sui the backbone of how value moves on the internet

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

Now live and fully rolled out on mainnet: Stablecoin transfers on Sui are free. No $SUI, no problem. Just send.

Corporate spend TAM is much larger than payroll. But we are happy to work with you as well @deel 😉

The future belongs to instant, massive stablecoin payments, but today’s vendor payments are held hostage by bank wire windows. Enter Sui x Ramp. Sui is now supported by finance platform @tryramp for $USDC payments, bringing fast, streamlined settlements.

Continuing our push to move crypto out of the current nonsensical "intranet blockchain" era Here is Sui Spheres - Multiple counterparties - Selective visibility - Predictable performance - Flexible cost models
May 14
Institutions want shared infrastructure. They don’t want full transparency, unpredictable costs, or crypto-native UX. That’s been the blocker. Today we’re introducing a new model: Sui Spheres 🧵

the post-quantum debate is about to fracture crypto into 2 camps one camp is going hash-based that's the path @adam3us is laying out for bitcoin. decades of peer review, conservative hardness assumptions, larger signatures the other camp is going lattice-based. falcon, or dilithium that's the path most high-throughput chains will be forced into because a hash-based signature runs multiple kilobytes and their transactions were sized for a different era every chain in this debate is going to commit to one algorithm forever, because their architecture gave them no other option the stablecoins moving across these camps will need a chain that speaks both every bitcoin holder bridging into defi will need a chain that speaks both every agent routing the cheapest path through a post-quantum world will need a chain that speaks both this is why we built @SuiNetwork the way we did our chief cryptographer @kostascrypto shipped the first stateless post-quantum signature for a blockchain in 2017-2018 9 years before this debate existed when every other chain hardcoded one signature scheme into the protocol, we built an authenticator layer where every algorithm gets a flag adding a post-quantum scheme means adding a flag, not a hardfork of the chain while every other chain shrank transactions to fit the cryptography of 2018 and ran out of room we built transactions with a 100x the space solana's transactions cap at 1232 bytes. ethereum's gas model penalizes anything larger sui's transactions cap at 128 kilobytes. that's nearly a 100x compared to solana sphincs at 8 to 50 kilobytes fits. dilithium at 2 to 4 kilobytes fits. falcon at under 2 kilobytes fits so does any combination of them in native multi-sig while every other chain is now staring down a forced choice about which algorithm to commit to, we never put ourselves in that position @adam3us can be right about bitcoin. @toly can be right about solana. both can be right at the same time the chain that doesn't have to pick a side is going to ultimately win and that's @SuiNetwork
lattice based signatures are good-enough for docusign, but not for bitcoin.

Today we’re introducing Predict. Onchain options have been stuck at ~$100M in TVL while perp DEX volume hit $7T last year. The gap is architectural. Predict is the third composable financial primitive in the DeepBook stack. Builders can create binary markets, options (calls, puts, spreads), leveraged products, and structured instruments that integrate directly with Spot and Margin. Testnet is live. Mainnet coming soon. Spot. Margin. Predict. blog.sui.io/introducing-deep…

Dear Lazyweb, which Fortune 500 company should we acquire? My buddy at the neighborhood credit union will issue a high-confidence letter for the loan. Half stock, half cash #Gamestop_math

Time flies. Happy birthday Sui. Here is to ♾️ more 3 years.
Sui turns 3. 3 years of Sui Mainnet. 3 years of building a full stack. 3 years of the best community. To the builders and the believers: the journey is only 1% done. Happy birthday, Sui.
