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, permits customers to add identification paperwork offline to privateness servers and share nameless “proofs” to organizations. Because of this, these corporations don’t must retailer this information themselves.
Customers who generate their very own proofs can then decide precisely who they share their info 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 report from it, then use that report for age verification functions,” Pruden mentioned.
Pruden defined that on zPass, a two-step course of helps make sure that particular person identities are safely verified. First, the issuance of the report on-chain is predicated on the existence of a bodily report, 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 challenge the identification, and the identification is the doc primarily based 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 personal.
“Lots of zk identification techniques use a centralized proving system or have centralized sequencers — now we have a leveraged tailor-made [layer-1], now we have 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 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 personal and knowledge is publicly out there on a database, customers will be tracked.
“They might not be capable of see all of your info, however they will see who you’re sharing it with and the way typically you’re sharing it with them, and might 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 wish to create an area that helps kids and avoids them from being uncovered to potential predators or [predatory] content material,” he mentioned. “So our fundamental purpose [for now] is to lean into age verification.”
