We audit code.
But we also audit culture.
Because high TVL without internal security practices
is just a slower kind of vulnerability.

@NexusMutual time to launch a finality insurance for tradfi and cexes.
koeppelmann@koeppelmann
Under worst-case conditions, Ethereum finality can take a long time. But in practice, enough confirmations arrive in under 13 seconds to treat transactions as final. Bridges, CEXs, and L2s could accept deposits MUCH faster by counting confirmations, not blocks.

Roots of Trust: sovereign tech as the last bastion against AI totalitarianism
A wide ranging discussion in Berlin on the tools and mindsets that prevent AI from turning you into its slave:
- paranoia
- verifiable silicon
- supply chain hygiene
- private internet money
- surveillance with accountability
- farming skillzzz
Will post recording when it’s up

The industry got one thing badly wrong: it stopped listening to users. Now institutions want to become those users. Time to actually listen. Listen to @JphFritsche at @dappcon 2026.

Zero knowledge: prove something happened without revealing what happened. Sounds impossible. It's just math. @JphFritsche explains @dappcon

The institutional blockchain stack just got an upgrade.
Together with @LineaBuild, we show how ZK is a natural enabler of locally controlled, globally accessible, and efficient on-chain financial markets.

The next challenge is enabling institutions to settle assets and cash across chains without exposing sensitive data or creating new settlement risk. Linea and @bermudabayzk show that private, atomic and verifiable settlement is possible. Blog post ↓ linea.build/blog/atomic-dv…

Privacy is a human right
Dappcon@dappcon
── Dappcon 2026 Speaker ── Banks have been told privacy and auditability are opposites. They're not. 🎙 Dr. @JphFritsche · @bermudabayzk ↳ "Enabling Institutional Adoption: Privacy, Auditability and Verification" Jan will give a talk on how zero-knowledge proofs and selective disclosure dissolve the trilemma holding institutions back from public blockchains — making systems that are private by default, auditable on demand, and verifiable on proof, without retreating to permissioned chains.

Unfortunately, there is a hack related to @gnosispay and the "delay module".
Please be patient while we try to contain the damage. Rest assured, Gnosis will cover all user losses.

What issuers can now do, live today:
🚫 Act on one address, not the whole contract
⏱ Spending limits on autopilot
↩️ Clawbacks when legally required
🔑 Safe-native, multisig-ready out the box
🔓 Permissionless to set up
Targeted, not total. Compliance without surveillance.

A single court order just froze the entire confidential cUSDC token contract of Zama.
At Zama it hit mostly a hacker's funds, so it stayed clean.
But the real danger is what this means for every other privacy protocol: freeze the contract, freeze everyone in it.
Here's the problem. 🧵 1/6

Update from ZachXBT. What does this mean for privacy protocols?

Fair point.
With centralized stablecoins you have to assume the kill switch can be pulled. That risk is real.
So there are two honest options:
give issuers tools to freeze one address instead of the whole pool, or use decentralized stablecoins in the pool.
We built @bermudabayzk to support both.
English
circle just blacklisted @zama's cusdc contract. 12.6m of user funds instantly frozen.
fully homomorphic encryption means absolutely nothing when the underlying asset has a master kill switch. zero transparency, same playbook as the 16 wallet freezes from march. wrapping fiat stablecoins in privacy math is just building sandcastles on their servers.
permissionless tools cannot exist on top of permissioned assets. if they can pull the plug, you don't own the liquidity. true privacy requires base layer decentralization.

@bermudabayzk Issuers have to resort to this practise if they don't have another choice.
English
@bermudabayzk Issuers need control - in this case, the only way to enforce the policy was to freeze the whole pool.
