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.
The emerging machine-to-machine (M2M) economy is exposing a fundamental limitation in our financial plumbing:traditional banking rails were designed for human biological rhythms and bureaucratic overhead, not autonomous code.
If users and builders do not understand the mechanics of post-quantum security, account abstraction, and autonomous agent delegation, they will inevitably default back to centralized custodians and fragile legacy habits. Achieving durable adoption requires:
Demystifying Cryptographic Hygiene: Educating developers and organizations on why migrating away from legacy elliptic curves is urgent, and how to manage post-quantum key pairs without prohibitive operational friction.
Mastering Agentic Governance: Training builders to implement precise policy bounds, such as time-locks, multisig overrides, and transaction limits via ARC-58, so that autonomous agents cannot drain treasuries or execute unvetted logic.
Fostering a Competent User Base: Shifting the narrative away from speculative metrics toward functional literacy. True adoption is measured by the volume of people who can confidently audit their automated systems, understand their cryptographic exposure, and participate in decentralized governance.
Autonomous agents will not wait for legacy finance to catch up, nor can they afford to build on cryptographic quicksand. As high-speed AI commerce collides with the timeline of quantum computing, the networks that succeed will not only be those with the fastest algorithms, but those backed by an educated, capable community equipped to put that security into daily practice.

INDIA IS MAKING ITS MARK ON THE GLOBAL x402 STAGE! 🇮🇳
Three projects in the global Top 5. Six in the overall Top 20. A huge shout-out and heartiest congratulations to all six teams on this incredible achievement! 👏
#2 Finality - @FinalityAI
#3 Tendril - @tendrilhq
#4 PRISM - @PRISMx402
#10 Sikho AI - @SikhoAi_x402
#16 Inquvia - @Inquvia2026
#18 HelixBox - @helixboxide
A powerful showcase of the talent, ambition, and innovation emerging from India’s builder ecosystem, only on #Algorand.
India isn’t just competing on the global x402 stage; we’re helping shape its future. 🚀

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.

Sound on!
Gemini 4 Argon built a 3D periodic table synced to Tom Lehrer’s song, “The Elements.”
Created in @Antigravity, it animates orbiting electrons, atomic data, and light spectra.

🧵 Big ARCs update for the @Algorand ecosystem!
Signing arbitrary data with post-quantum schemes on wallets, a network-wide ASA circulating supply endpoint live on MainNet, and the ASA Metadata Registry closing in on launch.

O desconto no Imposto sobre os Produtos Petrolíferos e Energéticos (ISP) foi estendido até 31 de dezembro.
A medida corresponde à devolução do adicional do IVA arrecadado pelo Estado por via do aumento do preço dos combustíveis.
