In Zcash, a viewing key lets an account holder reveal shielded transaction history to a party of their choosing. The keys are live and user-controlled. Builders and policy advocates are still at work on getting them to serve the compliance workflows that could use them. On August 17 the
Data is encrypted at rest, in transit, and in use. Ciphertext on disk and ciphertext on the wire has two decades of audit practice behind them. "In use" reads as if it were the same kind of claim. Is it? What did the consortium decide? The Confidential Computing
Back in late July, Zama switched on a confidential swap venue on Ethereum mainnet, in private beta ahead of a September public launch, that makes it possible for a trader to submit an encrypted intent hiding the amount, the slippage tolerance, and the direction of the trade. It relies on
A confidential workload that spans a CPU enclave and a GPU produces attestation evidence at every hop, and deployment guides call the result "attested." But if you decompose what the reports contain you're left with grey areas: what was measured versus what executes, when the evidence
Modeling agent messages across ten-node relay networks pushed OpenVTC to adopt the Trust Spanning Protocol and to restructure its stack so the transport question stays routine. Glenn Gore walks through the decision, and DIDComm's Sam Curren explains the design. When the OpenVTC project modeled how its agent
Weeks before Ironwood, the upgrade meant to make its supply checkable again, Zcash cannot prove a four-year-old bug in its largest shielded pool was never exploited. That sounds like an argument against privacy, but the systems it is measured against fail the same way, at greater cost. The
Silicon, math, and a quorum of nodes all ship under the same label. The phrase sets your threat model. On 22 June, two companies shipped products they both called confidential computing. Anjuna, a Palo Alto enterprise vendor, announced Overwatch, a governance layer for AI agents that runs attested inside a
How the unlinkability requirement is being engineered, and the layered cryptographic schemes that may carry it into production Anything deployed today has a shelf life of six to seven years before you have to swap it out for a post-quantum state. That's a short time to amortize.
In barely a year, the industry has agreed on how AI agents should find one another and hand off work. It has reached no such agreement on the harder question as to how an agent proves what it is allowed to do. One of decentralized identity's architects argues
An attestation can prove an enclave is genuine and unaltered since the moment it booted. That's great, but it cannot prove the code inside matches the source you reviewed. Caution, the platform spun out of the security firm Distrust, is built on the wager that providing an attestation
pERC20, EIP-8182, and STRK20 arrived inside three months, alongside ERC-7984, the incumbent. They are four answers to different questions and the people building them are arguing. Within a single quarter, the EVM world produced four separate ways to hold and move a token without publishing the balance. In
The standards for the EU digital identity wallet are largely set. Markus Sabadello argues the framework chose the older, established options over the ones the decentralized-identity community built, and while these choices were practical, they were never merely technical, and this matters because each shaped who ends up in
