A protocol designed to make use of zero information cryptography to confirm identities has landed on the Aleo blockchain, a zero information privateness (ZKP) community.
The protocol, known as zPass, allows customers to add id paperwork offline to privateness servers and share nameless “proofs” to organizations. Because of this, these corporations don’t have to retailer this information themselves.
Customers who generate their very own proofs can then decide precisely who they share their data with and simply how a lot private information they want to reveal.
Alex Pruden, Aleo’s CEO, instructed Blockworks in an interview that zPass represents the implementation of a analysis paper into zk-creds.
“The thought of zk-creds was to take a US passport, create a digital file from it, then use that file for age verification functions,” Pruden mentioned.
Pruden defined that on zPass, a two-step course of helps be certain that particular person identities are safely verified. First, the issuance of the file on-chain relies on the existence of a bodily file, after which it’s the capability for every particular person to regulate their very own privateness keys which generate the proof of id.

“The important thing piece of what zk-creds and zPass does is to difficulty the id, and the id is the doc primarily based on a real-world bodily doc,” he mentioned.
John Reynolds, a product supervisor for Aleo, famous that current zk id methods both depend on centralized proving schemes, or are decentralized however not non-public.
“A whole lot of zk id methods use a centralized proving system or have centralized sequencers — we’ve got a leveraged tailor-made [layer-1], we’ve got the power for customers themselves to behave as provers, they will generate proofs, ship these proofs to Aleo, decentralized validators can validate these proofs, and the Aleo blockchain won’t push all of this overhead verification to 3rd get together methods,” Reynolds instructed Blockworks in an interview.
On the be aware of decentralized id options, Reynolds mentioned that as a result of they aren’t non-public and data is publicly obtainable on a database, customers might be tracked.
“They might not be capable of see all of your data, however they will see who you’re sharing it with and the way usually you’re sharing it with them, and may goal you because of that,” he mentioned.
At launch, zPass will focus totally on offering zk age verification and creating child-safe areas on-line, Reynolds mentioned.
“We need to create an area that helps youngsters and avoids them from being uncovered to potential predators or [predatory] content material,” he mentioned. “So our primary objective [for now] is to lean into age verification.”
