Parity Technologies Unveils Proof-of-Ink Web3 Individuality Solution Targeting Mainstream Adoption

The new solution, coined Proof-of-Ink, will enable users to prove their digital individuality in a privacy-preserving manner through a unique tattoo serving as proof of digital citizenship.

Parity Technologies is launching a new Web3 individuality solution, which is a key missing piece for mainstream Web3 adoption, according to Gavin Wood.

The new solution, called Proof-of-Ink, will allow users to prove their digital individuality in a privacy-preserving way, with a unique tattoo acting as a proof-of-digital-citizenship.

Proof-of-Ink is set to launch in Q4 2024, according to Wood, who is the co-founder of Ethereum, Polkadot and Kusama.

Speaking during a keynote address at Web3 Conference in Berlin, Wood announced:

“We have three digital identity solutions. I'm announcing two of them today, and one is further in development, but I can't tell you about that yet.”

Mainstream adoption is key for any technological paradigm, and Web3 adoption is no different, with experts like Wood hoping to create a more decentralized and user-centric internet, envisioned as a free public good to help humanity.

Proof-of-Ink: What we know so far

To add an element of privacy to the solution, Proof-of-Ink will require these algorithmically generated tattoos to be placed in a particular spot on the body, explained Wood:

“For each new user tattoo, the blockchain will generate a random number, which creates the algorithmically generated designs that are unique for all users.”

Users will need to pay a small balance of Polkadot (DOT) tokens or potential vouchers, which could be shared within the Web3 community ahead of the application's launch this year.

This will act as a type of Sybil resistance against spam requests, explained Wood.

Finally, Proof-of-Ink users will upload a video of the final three minutes of the tattooing process, which will ultimately serve as the evidence of the person's Web3 individuality.

Web3 individuality needs privacy to avoid financial censorship

Digital individuality solutions could help massively in mass Web3 adoption, as long as they can provide users with true financial privacy, said Wood:

“What we really want to be able to do is not have a signature associated with a transaction. Rather, we want to have a proof. A proof that does not identify us.”

According to Wood, famed whistleblower Edward Snowden was the first to highlight the importance of financial privacy to avoid censorship, which Wood explained as:

“The ability of an individual to make a payment without the sender being known to the recipient or third parties, such as the payment processor.”

Other examples of financial censorship include Visa and Mastercard's decision to suspend payments to whistleblower website WikiLeaks back in 2010.
