Aleo blockchain adds zPass, a ZK protocol for verifying identities 

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, referred to as zPass, permits customers to add id paperwork offline to privateness servers and share nameless “proofs” to organizations. Consequently, 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 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 is predicated on the existence of a bodily file, after which it’s the capacity for every particular person to manage their very own privateness keys which generate the proof of id.

“The important thing piece of what zk-creds and zPass does is to challenge the id, and the id is the doc based mostly on a real-world bodily doc,” he mentioned.

John Reynolds, a product supervisor for Aleo, famous that present zk id programs both depend on centralized proving schemes, or are decentralized however not personal.

“Quite a lot of zk id programs use a centralized proving system or have centralized sequencers — we now have a leveraged tailor-made [layer-1], we now have 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 is not going to push all of this overhead verification to 3rd occasion programs,” Reynolds instructed Blockworks in an interview.

On the notice of decentralized id options, Reynolds mentioned that as a result of they don’t seem to be personal and data is publicly accessible on a database, customers will 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 kids and avoids them from being uncovered to potential predators or [predatory] content material,” he mentioned. “So our fundamental objective [for now] is to lean into age verification.”
