A brand new digital identification regulation has come into impact within the European Union (EU), requiring member states to offer a minimum of one EU digital identification pockets to all residents and residents.
On Might 21, the EU updated its European Digital Id (EUDI) regulation, which was initially launched in February 2023, and acknowledged that it should be absolutely carried out by 2026.
It’s set to rework the best way European residents reside and work, with the digital ID pockets for use for electronically signing and storing paperwork; from college diplomas to coach tickets.
Thierry Breton, the EU commissioner for the inner market, mentioned the pockets will “revolutionize the best way European residents and companies interact with on-line companies by seamlessly integrating comfort, security and privateness.”
The European Fee has invested 46 million euros ($50 million) in 4 large-scale pilots to check the EU Digital Id Pockets. Moreover, they’ve introduced a second name for large-scale pilots to additional help the deployment of those wallets.
This improvement raises questions in regards to the look and performance of a government-issued digital ID pockets, in addition to how particular person privateness and regulatory compliance could be maintained on such a big scale.
Cointelegraph spoke to Dr. Jonas Gross, the CEO of Hakata, an organization offering “compliant privateness” options for Web2 and Web3 companies by way of the Mina Protocol.
The dialogue aimed to grasp the challenges builders face when integrating privacy-preserving options into digital ID options and to discover methods to beat these obstacles.
Dr. Gross mentioned for digital identification options, and significantly the EU digital identification, there are two “paramount” rules: A user-centric design and a privacy-first strategy.
“It must be ensured that the consumer is all the time on the middle and maintains possession of the confidential, private knowledge. Person knowledge, corresponding to identification knowledge, credentials, attestations, or private info, needs to be saved on the consumer’s gadget.”
He pressured that the consumer needs to be the only real resolution maker and have the liberty to determine which knowledge is shared and with whom, and this sovereignty needs to be a foremost design precept within the EU identification infrastructure.
Zero-knowledge proof answer
To make sure a privacy-first strategy and the confidentiality of non-public info, zero-knowledge proofs (ZKPs) are a Web3 instrument that might be used to make this attainable.
ZKPs would enable customers with the chance to solely reveal cryptographic proofs as an alternative of clear knowledge, and thereby protect their privateness. Dr. Gross mentioned:
“ZKPs have the potential to start out a brand new paradigm of compliance that breaks down knowledge silos round identification info.”
He gave a concrete instance of ZKPs getting used within the context of an identification answer, portray the image of a government-issued digital ID that sits on an finish gadget, aka a cellphone. Solely the consumer is aware of the data on this digital ID, which features a identify, handle, date of beginning, nationality, and many others.

“Think about that [someone] needs to purchase a glass of wine,” he mentioned. “Whereas ordering, the bartender needs to validate if [they] are older than 18 years. In right this moment’s world, this might imply exhibiting the ID to the bartender, thereby revealing the complete (bodily) ID.”
In such a scenario, attributes like handle and nationality, that are irrelevant to the bartender, are additionally revealed. Dr. Gross prompt that sooner or later, a selected ZKP might be shared to confirm somebody is older than 18 as an alternative of their complete ID. Consequently, the bartender would solely know that truth and nothing extra.
Dr. Gross emphasised that this is only one particular instance of ZKPs. They’ll take numerous types and may also be used to confirm various kinds of info within the context of identification. For example, they’ll show that an individual shouldn’t be from a selected nation or that they maintain a European passport.
He mentioned the described answer is strictly what they’re constructing out with Hakata.
“As ZKPs solely expose proofs as an alternative of clear knowledge — as described within the earlier instance — privateness is considerably enhanced and safety is improved.”
Developer challenges
Whereas implementing ZKPs as an answer could seem to be a simple reply to a few of the woes officers might probably face, behind the scenes builders could have a little bit of a problem on their arms to create such options at scale.
Dr. Gross mentioned a kind of challenges is the dearth of standardization within the ZK area, with each ZK tech stack working in another way and making it in order that interoperability shouldn’t be a given.
“This makes it very tough to construct purposes which can be speculated to work on totally different tech stacks,” he mentioned.
Moreover, in lots of international locations, the expertise remains to be within the technique of safety analysis to make it accessible to governmental and controlled companies.
“As a result of some cryptographic components of the ZK expertise usually are not but supported in commonplace client {hardware}, the adoption in regulated markets requires devoted options, e.g. cloud-based safety modules.”
Whereas not a problem, Dr. Gross additionally really useful that reference implementations — just like the EUDI Pockets Reference Implementation — needs to be made accessible open-source on GitHub by these growing the pockets.
This could enable “tech-savvy” individuals to take a look at the answer/pockets’s supply code. Consequently, one doesn’t have to belief the answer supplier concerning privateness however might as an alternative personally confirm that the best privateness requirements are met.
“I do see this transparency as an awesome driver for belief and in the end adoption.”
EU’s digital future
This new regulation will entail that each one member states present a minimum of one EUDI pockets to their residents and make the help of the pockets obligatory inside quite a lot of industries.
Such a improvement, in accordance with Dr. Gross, would assist the EU foster a rebuild of its full on-line infrastructure and put the digital identification in all related workflows of its digital ecosystem.
He mentioned with the EUDI pockets, “freaking out abroad within the case that the bodily ID can’t be discovered earlier than flying again dwelling, belongs to the previous.”
