Today we’re introducing Gemini 4 Carbon — our newest frontier model from @GoogleDeepMind.
Carbon is our strongest model with state-of-the-art cybersecurity and long horizon capabilities. Built for sustained agentic workflows, it delivers improved performance across domains — with greater alignment, transparency, and follow-through to respond to high-pressure tasks.
We’re rolling it out starting this week to cyber defenders through our Fairwind Program, with expanded access as soon as possible.

The @anthemawards, from @TheWebbyAwards, recognize organizations making an impact around the world.
Algorand-based payments startup @HesabPay_ is a finalist for the Community Voice Award in Humanitarian Action -- Product Innovation or Service.
#algofam, you know what to do 🗳️👇

I’ll be speaking at The Bridge by @TheTieIO today in NYC.
On a panel with Jay Pollack from VerifiedX, Joshua Lim (@joshua_j_lim) from Falcon X, and James Evans (@jimbo_evans) from Reciprocal Ventures. Moderated by @seanlippel.

🧐 O Orçamento do Estado é um dos principais instrumentos de decisão do país: traduz prioridades e define como são previstos e aplicados os recursos públicos.
Mas a história começou muito antes do formato que conhecemos hoje. 🧶

This is huge news for @Algorand
Canadian bank @VersaBank is piloting tokenized deposits on Algorand. ~$5B in assets, this is a great test case that will likely signal to other banks $ALGO value prop - particularly as a quantum solution.

@algo_surf updated, featuring information that is usually not captured by indexers. First, we have metrics like TPS and fees over time. Drag over the chart to zoom in, or explore any time slice from the presets and Period dropdown. You can get to the exact blocks by clicking block bars.
It is fun to click around and find TPS spikes - here are some TPS examples from my+@Urthoo's May 2024 ALGO+USDC load tests:
algo.surf/tps?range=2024-05&…
algo.surf/tps?range=2024-05&…
This is powered by surf-indexer, a new (unofficial) indexer that supplements data left out by the official one. It uses DuckDB and currently takes up just 750MB for the Mainnet data set. It is pretty fast at what it does, currently being served live (no cache) from a potato VPS and a laptop. You can see code and features here: github.com/d13co/surf-indexe…
There's a bunch of other features for you to discover around accounts. One of my favorites is the relationship between multisig accounts and sub-signers. Normally this relationship is only discoverable one-way (from multisig to sub-signer)
Now, for each account, you can see which multisigs they are a part of, as well as whether they have ever signed or not (as listing sub-signers is permissionless, so if an account hasn't signed for a multisig, they may not have been aware that they were part of it)
algo.surf/account/DTHIRTEENN…
There's also semi-hidden work on logic sigs, pending a bit of polish and labeling💅
Finally a topical one: there's a Consensus Upgrades page, which lists all consensus upgrades that have taken place. algo.surf/upgrades
Which brings me nicely to: Upgrade your nodes, algod 5.0.4 is out with a new consensus release.

Japan TODAY: @Algorand’s stablecoin market capitalization has surged nearly 25% in a week, reaching $97.07 million, according to DefiLlama data.
The network is now approaching the $100 million milestone, a level reached by only 26 other blockchain networks, putting algorand:native’s ecosystem growth in focus.
If the momentum continues, Algorand could potentially surpass the stablecoin market caps of @SonicLabs and @NEARProtocol, signaling further expansion in its stablecoin sector.

On the most aggressive timelines, quantum computers could crack old Bitcoin wallets within this cycle. Only two blockchains running today are built to be quantum-resistant: Quantus and Algorand. A big story with so few coins is what makes this narrative asymmetric.

Why Algorand payments don’t wait for extra blocks
On Bitcoin, two miners can find a block at the same time, and the chain briefly splits in two, which is called a fork. Payments on the dropped side are undone, so waiting six blocks, about an hour, is the common rule before a payment counts as settled.
@Algorand is built to stop those splits. Each new block goes to a vote, with voters picked at random from the algorand:native holders who help run the network. A block needs more than two-thirds of the votes to pass.
Because the chain does not split, a transaction is final the moment it lands in a block. Blocks arrive roughly every 2.8 seconds.
The design has a cost in a crisis. If the network splits or too many voters act dishonestly, Algorand stops producing blocks, and payments wait until enough honest voters can reach each other again to restart.

'People do not seem to perceive the risks'.
Algorand CEO William Herkelrath joined @FINTECHTVglobal, where he warned of the quantum computing risk that is coming and pointed out that Algorand has the solution.

We've been saying it for years, and it's finally being acknowledged ahead of Q-Day.
Algorand is built for the post-quantum future.
