⚙️How does Data2.cash work

How data become cash?

Mechanism

Users import metadata (eg., wallet accounts, Twitter accounts, GitHub accounts, etc) from data collectors into their account vault, tags will be found from metadata, and later, users can generate zero-knowledge proof from their tags, and link them to their ZK portrait.

Data users can use Data2.cash API to search for ZK identities using specific tags, and pay for the search, ZK identity owners get rewarded by providing their data.

How user get rewarded by providing their data

One example use case

Example use case

A DeFi project, let's say X.finance, wants to grow its user amount by reaching out to high-quality, users. They can now define their own tag:

1. Provided liquidity to Uniswap V3 before 1st June 2023

2. Traded on Curve or provided collateral on Aave before 1st June 2023

3. Being a Twitter follower of X.finance

4. Haven't used X.finance before

By using Data2.cash API, they can now have a list of ZK identities, and reach out to let them know X.finance. For users with a certain tag, they are more likely to get interested in X.finance, at the same time, they get rewarded for providing their data.
