The Web3 individuality mechanism will take a significant step forward with “Proof-of-Ink”, a new solution that requires a unique tattoo to verify digital citizenship. Developed by Parity Technologies, this mechanism aims to address a critical gap for mainstream adoption of Web3.

Gavin Wood, co-founder of Ethereum, Polkadot and Kusama, announced that Proof-of-Ink will launch in the fourth quarter of 2024.

Proof-of-Ink will enable users to prove their digital individuality while preserving privacy. This will happen through a unique algorithmically generated tattoo.

In his statement at the Web3 Conference in Berlin, Wood stated that they aim to distribute the basic palette and launch the application in the last quarter of this year. He also stated that they plan to offer two other digital identity solutions next year. However, he did not provide information on the details of these two additional solutions.

Mainstream adoption of Web3 is a critical factor for the success of the technology. Web3’s vision is to create a decentralized and user-centered internet, designed as a free public good that can help humanity.

Proof-of-Ink will require algorithmically generated tattoos on a specific part of the body for privacy protection purposes. Wood stated that this design will be in the same place for all users and will guarantee privacy. The design will be provided by a signed and untrusted entity on-chain, which aims to preserve individuality.

For each new user tattoo, the blockchain will algorithmically generate random numbers to create unique designs. Users will pay a small balance by spending Polkadot tokens or vouchers that can be redeemed within the Web3 community before the launch of the Proof-of-Ink app.

This process will act as a Sybil resistance against spam requests, thereby creating a measure to verify users’ true intentions.

Proof-of-Ink users will prove their digital individuality by uploading a video of the last three minutes of the tattoo process. This video will serve as proof of one’s Web3 individuality.

Digital individuality solutions can significantly increase mass Web3 adoption, but they must be solutions that provide true financial privacy, Wood said. “What we really want to do is create evidence that does not identify us, rather than a signature that identifies a transaction,” he said, emphasizing the importance of this goal.

According to Wood, famed leak expert Edward Snowden was the first to highlight the importance of financial privacy to avoid censorship. Snowden’s emphasis on this issue revealed the critical importance of protecting financial privacy.

Other examples of financial censorship include Visa and Mastercard’s decision to suspend payments to WikiLeaks in 2010. Such censorships further highlight how important it is to protect digital individuality and the potential of Web3 technology in this area.

Proof-of-Ink could shape the future direction of digital authentication and bring Web3 adoption to a wider audience. This innovation can enable Web3 technology to appeal to a wider user base by being more secure and prioritizing personal data privacy.
