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 identification paperwork offline to privateness servers and share nameless “proofs” to organizations. Because of this, these firms don’t must retailer this knowledge themselves.
Customers who generate their very own proofs can then decide precisely who they share their info with and simply how a lot private knowledge 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 concept of zk-creds was to take a US passport, create a digital document from it, then use that document for age verification functions,” Pruden mentioned.
Pruden defined that on zPass, a two-step course of helps be sure that particular person identities are safely verified. First, the issuance of the document on-chain relies on the existence of a bodily document, after which it’s the skill for every particular person to regulate their very own privateness keys which generate the proof of identification.

“The important thing piece of what zk-creds and zPass does is to difficulty the identification, and the identification is the doc based mostly on a real-world bodily doc,” he mentioned.
John Reynolds, a product supervisor for Aleo, famous that current zk identification techniques both depend on centralized proving schemes, or are decentralized however not non-public.
“Lots of zk identification techniques use a centralized proving system or have centralized sequencers — we’ve a leveraged tailor-made [layer-1], we’ve the flexibility 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 techniques,” Reynolds instructed Blockworks in an interview.
On the word of decentralized identification options, Reynolds mentioned that as a result of they don’t seem to be non-public and knowledge is publicly accessible on a database, customers could be tracked.
“They might not be capable to see all of your info, however they will see who you’re sharing it with and the way usually you’re sharing it with them, and might goal you on account 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 aim [for now] is to lean into age verification.”
