We co-designed Guardian alongside @0xMiden to solve private-state coordination and recovery without giving up custody.
Great to see it behind Bread, a wallet where sending, swapping, and receiving stay off the public chain by default.
Introducing Miden Foundry
@0xMiden devs can now preview transactions before they hit the chain.
Walnut is building Miden Foundry in partnership with Miden. The first tool, miden call, ships in midenup v1.0.1.
Thread time 🧵
Mainnet is a few weeks away.
A few things Testnet v0.16, our final major testnet release before then, brings:
🔸 Fees on testnet
🔸 Lighter web applications
🔸 Better swaps and bridges
🔸 Stronger privacy for transactions
Ethereum has cast call: dry-run a contract call without sending a tx.
@0xMiden now has miden call from @walnut_dev.
Same job — run a procedure, see what it returns — plus the Miden-shaped extras: notes, storage maps, vault diffs. Runs on your laptop. Nothing hits the network.
First brick of Foundry-like tooling, not the whole toolkit. walnut.dev/blog/introducing-…
Very cool! We are doing something similar in Miden. The VM is already migrated to BLAKE3, and we'll have this released in the next few weeks.
Interestingly enough, the performance degradation when moving off of Poseidon2 wasn't as dramatic as I thought. Overall, the impact was under 30%.
ZisK v1.3.0-alpha release 🚀
ZisK is moving beyond arithmetic hashes with BLAKE3 strengthening security while outperforming our prior Poseidon1 version:
⚡ 7.43s p999 on 4×5090
⚡ 5.14s p999 on 8×5090
🛡️ 128-bit provable security
🔐 Post-quantum secure
This is a major step toward faster and safer proving.
Release notes: github.com/0xPolygonHermez/z…
Businesses still can’t go all in onchain because blockchains are too transparent.
Moving more of their operations onchain today means giving away information they simply can’t afford to expose.
In this episode of Privacy Podcast, @btschiller speaks with @Corpetty of @Logos_network about full-stack privacy, metadata leakage, and why protecting the transaction itself is not enough if the rest of the transaction lifecycle still leaks information.

Miden co-founder @azeemk argues the answer to rogue AI transactions may be simple: don’t ask the agent to behave, make the forbidden transaction impossible.
"We ended up creating a solution to our own problem, which we call Guardian. You can think of it like a two-of-three multisig, where you have a hot wallet, a cold wallet key that's stored, and then you can have a third guardian that would be a signer."
"As we started building out, we started seeing, wait, you can actually put an AI in here and give the AI parameters it needs to follow."
"The human would be able to enable guardrails into Miden Guardian, and then have it do the things it wants while being comfortable knowing you can't somehow convince the agent to send $300,000 to someone."
"But if you could encode that it literally can't, that's fascinating."
@0xMiden
Miden co-founder @azeemk predicts autonomous AI agents will need privacy for the same reason humans do: not every financial action should be public.
"If I asked what city you live in, you'd tell me. But if I jump to what's your salary, or how much money do you have in the bank, those would be things where only selective people you would want to disclose that to. People have an understanding of selective disclosure intuitively."
"Right now on blockchains, everything you're doing is built on top of fully public ledgers and public rails."
"What I haven't really seen nearly enough of yet is people realizing that agents, crypto, and privacy all need to actually come together in a Venn diagram."
"We're moving towards a world where agents will be able to fully act autonomously. If you are an autonomous agent, why wouldn't you want the idea of privacy in here?"
@0xMiden
Have been waiting for a while to talk about this! Great UX and advanced tech in single wallet:
- Private by default.
- Post-quantum ready.
- Safe (via Guardians).
- Feature-packed and easy to use.
- Fast ZK proofs under the hood (under 3 seconds on mobile).
- And many many more.
post quantum privacy blockchain. mainnet coming soon.
literally some of the most cutting edge cryptography, protocol engineering, and sleek UX/DevEx in the entire industry.
The first issue of The Index features @azeemk, crypto’s true renaissance man.
In our debut profile, @jbensonwrites tells the story of a man who “had a goal when he was younger: to get rich. Not just vacation-home rich or fancy-car rich.
He wanted to be filthy, inconceivably, awe-inspiringly rich.”

Exciting! v0.17 will be the mainnet release :)
As usual, there are tons of things in this release, but I'll highlight just two:
- Miden's fee model is really unique and lays the groundwork for very exciting functionality (fee sponsorships, built-in multi-token fees).
- The multi-level disclosure capabilities that range from user-controlled selective disclosures to network-level forensic analysis, and the flexibility to configure these as required for specific deployments.
