The final 13 years have seen blockchain know-how evolve into quite a few use circumstances — finance, information, logistics and safety, amongst others. Nonetheless, the concept of utilizing blockchain’s immutable capabilities to ID people acquired new life when Changpeng “CZ” Zhao visited the island nation of Palau to kick off its digital residency program.
The blockchain id administration market is estimated to grow by $3.58 billion within the span of 5 years from 2021 to 2025. Key elements embody the rising demand for digitalization and privacy-respecting identity solutions. Consequently, a myriad of options breached the market serving this want within the type of nonfungible tokens (NFT), distributed ledger know-how (DLT) and barebone blockchain know-how.

Contemplating the plethora of use circumstances that blockchain can serve on a day-to-day foundation, quite a few authorities organizations started experimenting with the know-how — weighing closely on central bank digital currencies (CBDC) and verifiable and immutable consumer id.
Issues with conventional IDs
Appropriately figuring out — or ID-ing — a person has at all times been paramount to governments to make sure focused supply of providers and allowances, amongst different necessities, which holds true to this present day. Nonetheless, ongoing developments in know-how empowered most of the people with instruments to create IDs visually similar to the unique. Given blockchain’s functionality to retailer immutable data, authorities see the know-how as a combating probability towards fraud associated to ID theft and fakes.
With conventional paper-based IDs comes the problem of confirming their legitimacy throughout totally different programs. Historical past has proven how folks efficiently use pretend ID playing cards to assert unauthorized entry to a myriad of advantages. Nonetheless, technological developments akin to blockchain have offered authorities with the chance to challenge verifiable certificates and IDs whereas making certain scalability, pace and safety of the id administration system.
Efforts on this entrance noticed the rise of a brand new ecosystem comprising varied blockchain-based digital ID choices. For instance, Shubham Gupta, an Indian Administrative Service (IAS) officer, not too long ago spearheaded the launch of a Polygon-based system for issuing verifiable caste certificates on behalf of the federal government of Maharashtra.
Talking to Cointelegraph, he stated, “if id administration programs need to be rated on a scale of 0 to 1 primarily based on decentralization and particular person management, conventional centralized ID programs will probably be on the far left and totally self-hosted, public blockchain-based IDs on the intense proper.”
Types of blockchain-based digital IDs
Whereas blockchain know-how can and has been used as-is for sustaining immutable data over the web, improvements spanning over the past decade resulted within the start of sub ecosystems round the usage of blockchain know-how.
“The concept of blockchain-based digital IDs has been floating round for fairly some time however got here into the limelight with the current NFT increase,” blockchain adviser and Bundlesbets.com CEO Brenda Gentry informed Cointelegraph.
Whereas NFTs have been first marketed as a device to characterize real-world objects together with mental and bodily property, the know-how discovered itself well-suited for a wide range of functions. Not too long ago, authorities organizations have begun testing NFTs for ID-ing residents as means to scale back operational prices.
“Large-scale implementation of blockchain-based digital IDs — like issuance of nationwide id playing cards akin to passports and driving licenses — takes time however I strongly imagine that’s the vacation spot that the world ought to transfer towards,” Gentry added. Along with serving to authenticate folks, blockchain know-how discourages counterfeiting, tampering or id theft makes an attempt.
Citing the involvement of luxurious manufacturers and artists that promoted the usage of NFTs to authenticate the legitimacy and possession of a product or artwork, Gentry opined that “luxurious objects could be checked for his or her authenticity on-chain which utterly eliminates the possibility of proudly owning a counterfeit product.”

Neil Martis, the co-founder and venture lead of LegitDoc, which is thought within the house for delivering quite a few blockchain-based certificates and ID options to the state governments of India, envisions a higher adoption of public blockchain-based ledgers over the following decade. Web3-native decentralized IDs will play an incremental position in figuring out customers and authenticating them to take part in several types of Web3 native transactions.
Advantages of blockchain-based digital IDs
Whereas blockchain’s elevator pitch is closely inclined towards immutability, the know-how boasts a number of benefits over conventional software program and paper-based programs. The opinions concerning the advantages of blockchain boil all the way down to the management over private data.
Self-sovereignty stands as one of many greatest advantages of blockchain-based digital IDs, in keeping with Martis. Because of this blockchain empowers customers to share partial or selective data with their service suppliers as an alternative of handing over their full id.
With blockchain-based IDs eradicating the misuse of knowledge, consultants envision the start of a really trustless system with out the involvement of third events. Gentry, too, reiterated verifiability, traceability and uniqueness as a number of the main advantages led to by blockchain, as she highlighted that blockchain IDs can’t be duplicated as a result of it is on the distributed ledger. “All of the Digital ID could be verified on the blockchain and could be traced again to the house owners’ account which will also be used for Know Your Buyer,” she added.
Limitations of blockchain-based digital IDs
Mainstream acceptance of blockchain-based digital IDs will finally need to imply overcoming probably the most urgent challenges that threaten to hinder its adoption. A number of the roadblocks that stand out within the present panorama embody a scarcity of schooling among the many lots and a supportive regulatory setting.
On the schooling entrance, Gentry has observed a fast-changing state of affairs led to by mainstream discussions and widespread adoption of the know-how. Nonetheless, the creation of pro-crypto laws will want higher intervention from business gamers to assist nations and establishments get onboarded onto the blockchain community.
Martis concurred with Gentry’s ideas on laws as he highlighted that blockchain IDs, regardless of how decentralized, will want attestation or recognition by the issuing authorities. He added: “if the issuing authorities don’t acknowledge the validity of the blockchain IDs, then the identical can’t be used for availing a majority of public providers. This in my view is the most important limitation.”
Blockchain of selection for ID-ing folks
Given {that a} majority of real-world id programs are beneath the purview of governments and sovereigns, Martis envisions higher adoption of permissioned distributed ledger networks for issuing Identities that require authorities providers.
Gentry famous that selecting the proper blockchain for IDing folks or items would require weighing the distinctive benefits and limitations of the varied blockchain ecosystems. Whereas highlighting the prevailing considerations akin to Ethereum’s fuel charges or Solana’s notorious outages, the blockchain advisor prompt that Binance’s BNB Chain is the proper selection of blockchain due to its excessive transactions per second and low latency and costs.

Talking from private expertise, Gupta shared that Indian state governments have a tendency to decide on a center floor whereby as an alternative of a single authority totally answerable for citizen identities, a bunch of unbiased departments will share a standard distributed ledger that hosts citizen identities, anchored periodically on a public blockchain.
The Maharashtra authorities is at present working to deploy a scalable blockchain-based ID system for a tribal inhabitants of 1.2 million. Martis explains that the IDs created will probably be utilized by varied departments to carry out analytics and establish the precise beneficiaries for varied nationwide schemes.
Whatever the challenges that decelerate blockchain adoption throughout enterprise verticals, some great benefits of the know-how make its dominance inevitable. Authorities organizations and personal entities have amped up efforts in uncovering futureproof fintech options through blockchain improvements. Blockchain disruptions which are well-positioned to go mainstream along with id administration embody localized CBDCs, provide chain options and cross-border settlements.
Decentralized identities or DIDs (decentralized identifiers) have but to see wide-scale implementation. In response to Martis, they need to be settled or issued by extremely decentralized public blockchains which are exterior state management, including that “Bitcoin and Ethereum stand out as the apparent selections on this regard.”
