The idea of digital identification is gaining fast traction throughout the globe. 4 of the world’s 5 most populous nations – China, India, Indonesia, and Brazil – are in various stages of implementing government digital identity schemes, as are many different governments across the globe. Nonetheless, at the moment, there are totally different approaches when it comes to the know-how used to handle a digital identification system, with some worrying implications for residents’ privateness.
The primary concern is the diploma of management {that a} centralized digital identification program will give to governments. Even trying on the progress made within the nations beforehand talked about, it’s simple to see why that is of concern. The Chinese language authorities is understood for its surveillance of residents. India’s Aadhar digital identification system has additionally come beneath fireplace, with petitioners stating that the federal government is utilizing the scheme to create a surveillance society and that it poses a menace to nationwide safety.
Decentralized Self-Sovereign Identification is the Solely Answer
The privateness and safety considerations round centralized digital identification methods are very actual. Even when at the moment’s authorities is utilizing citizen’s knowledge for reputable and benign functions, democratically elected governments are momentary by definition. Tomorrow’s elected officers will inherit the identical knowledge set and could also be ready to make use of it for extra sinister functions. The Snowden revelations in 2014 revealed the extent to which governments have already gone in breaching privateness legal guidelines.
Subsequently, if digital identification is to achieve widespread adoption with out vital limitations to beat, blockchain know-how is sort of a no brainer. Decentralized networks have confirmed to be extremely resilient in opposition to attackers, eradicating the safety menace.
Moreover, equipping residents with their very own personal keys would offer the essential aspect of self-sovereignty by introducing a consent-based mannequin. Residents might decide which entities have entry to which components of their digital identification. Improvements in blockchain privateness protocols, together with zero-knowledge proofs, provide much more advantages by permitting somebody to confirm identification with out essentially having to see it for themselves.
The European Union has already acknowledged that blockchain is the best platform for its personal digital identification answer, having arrange its Electronic Self-Sovereign Identity Framework Lab as a part of the European Blockchain Companies Infrastructure initiative.
Blockchain Identification for Blockchain Adoption?
Utilizing blockchain as a basis for digital identification has broad functions in changing present paper-based identification paperwork. Nonetheless, digital identities might additionally show to be an enabler for the adoption of blockchain know-how itself. Many use circumstances of blockchain are put ahead with out mentioning the barrier {that a} lack of identification creates.
As an example, blockchain in promoting is commonly mentioned within the context of eradicating fraud by eliminating faux advert site visitors. Nonetheless, with out some sort of verifiable identification answer, there’s nothing to cease fraudsters from organising a number of blockchain accounts. The identical applies for a lot of different use circumstances, equivalent to blockchain-based platforms aiming to fight faux information or troll social media profiles.
So it’s maybe unsurprising that many platforms at the moment are seeking to plug the decentralized identification hole. With a number of use circumstances in blockchain ecosystems and in the actual world, there’s ample alternative to create a basis on which many different functions can begin to flourish.
Concordium is one instance. It’s a decentralized public blockchain platform with a self-sovereign digital identification layer embedded into its know-how stack, on account of launch on mainnet in early 2021. The platform is at the moment working on testnet, and has attracted greater than 3,000 customers to enroll and create their very own digital identification since October.
Concordium’s identification answer supplies a bridge to the present problem of bodily identification paperwork by utilizing exterior identification suppliers. When a consumer, which can be a person or entity, creates an account, the identification supplier requests a duplicate of their digital or bodily ID.
As soon as that is verified, the supplier uploads a zero-knowledge proof verifying the ID onto the Concordium blockchain, permitting the consumer to transact in whole privateness. Within the occasion that there’s a authorized must determine a consumer, then an “anonymity revoker” – a 3rd celebration appointed by Concordium – can order the identification supplier to decrypt the consumer ID primarily based on a authorized request from the authorities. Nowhere on this course of can a single celebration revoke any consumer’s identification, however the course of is decentralized.
Concordium boasts a powerful workforce lineup bringing experience from giant, multinational firms and educational analysis in blockchain and cryptography. CEO Lone Fønss Schrøder holds board-level positions at IKEA and Volvo, whereas Concordium’s founder, Lars Seier Christensen, additionally based Danish funding financial institution Saxo in 1992. With an intensive community of senior contacts within the enterprise world, there’s a excessive expectation that Concordium’s answer will acquire fast traction amongst giant enterprises.
An Array of Use Circumstances
The use circumstances for this are virtually countless. Within the context of the controversial discussion round “well being passports,” these with immunity to any given illness might show their credentials with out having to reveal any of their well being knowledge. Individuals wouldn’t have to go away a duplicate of their passport at each resort check-in desk or on each web site promoting age-restricted merchandise.
Blockchain entrepreneurs claiming to unravel fraud would have verifiable technique of doing so, as customers might solely create an account primarily based on having their digital identification authenticated.
There are additionally loads of eventualities the place such an answer might be of profit to companies eager to transact with each other. At the moment, enterprise blockchain adoption has been restricted to permissioned networks, akin to non-public members golf equipment the place the prevailing members vet newcomers. A part of the rationale for that is the dearth of identification verification constructed into public blockchain infrastructure equivalent to Ethereum.
Subsequently, Concordium gives the total advantages of decentralized public blockchain infrastructure to enterprises who want an assurance that they aren’t risking transacting with criminals or cash launderers.
After all, Concordium isn’t the one platform engaged on decentralized self-sovereign identification options. One of many different best-known is probably Sovrin, developed on Hyperledger Indy in collaboration with IBM and different companions. Nonetheless, the most important distinction between Concordium and Sovrin is the truth that Hyperledger stays a permissioned community, whereas Concordium is permissionless.
Because the world turns into more and more digitized, and our private knowledge turns into ever extra priceless, the necessity for a self-sovereign identification answer turns into more and more crucial. Nonetheless, now that there are working blockchain-based identification instruments coming onto the market, there’s each motive to stay optimistic that they may assist the know-how fulfill its authentic promise whereas giving us management over our identification.
