The launch of blockchain-based digital passport platform Worldcoin has had a polarizing effect on the cryptocurrency community, with questions around its centralization, privacy and security highlighted.
Worldcoin released its protocol token on July 24, with major exchanges like Binance announcing support for the token. The project consists of a privacy-preserving digital identity (World ID) and its associated ecosystem token (WLD) which users receive upon creation of a wallet.

In order for users to join the ecosystem, they have to provide a scan of their iris through one of Worldcoin’s specialized Orb hardware devices. This step provides proof-of-personhood that is cryptographically secured and used as a World ID, Worldcoin founders Alex Blania and Sam Altman wrote in a letter at launch.
“This lets you prove you are a real and unique person online while remaining completely private.”
The global digital passport is set to be stored locally on user’s mobile devices and used to prove their identity in a privacy-centric manner. The concept aims for World IDs act as a “proof of personhood” that make use of zero-knowledge proofs (ZK-proofs) to protect the underlying data, including biometric, KYC and AML data.

Worldcoin will also enable users to “reserve” their respective IDs with a phone number in select countries, with an iris scan required to complete the process and receive a World ID.
Ethereum co-founder Vitalik Buterin was among a number of industry figures to comment on the launch of Worldcoin, given the potential for biometric proof of personhood.

In a lengthy blog post unpacked by Cointelegraph, Buterin delved into the technicalities of proof of personhood blockchain protocols and the potential benefits and pitfalls of projects that are blazing a trail for the use case.
Buterin highlighted a key raison d’être for proof of personhood protocols in being able to prove human identity and be used to distribute universal basic income in the future.
“Worldcoin is unique in that it relies on highly sophisticated biometrics, scanning each user’s iris using a piece of specialized hardware called “the Orb”.”
