• Data2.cash is a user data asset trading protocol that allows individuals to earn from their data without compromising their privacy.

• Users can aggregate their web2 and web3 data on Data2.cash, creating an anonymous profile through blockchain, and provide behavioral data through this profile.

• The first data consumer Dapp allows businesses to establish an peer-to-peer channel with high-quality target users, reducing growth costs.

• Our product for individual users is now live, and early adopters can now earn a special tag.

Alice wakes up, turns off her alarm, buys a coffee, and takes a taxi to work. During lunch, she watches an episode of a TV show. After work, she uses a map app to find a nice restaurant for dinner. When she gets home, she finds an envelope on the ground containing $5 and a note: "This is the value generated by your data, please check." In fact, actions like turning off an alarm, buying coffee, taking a taxi, and searching for a restaurant are all data produced by Alice, which have value all the time. However, we don't see the $5 in the envelope when we get home from work.

Data on the internet is being monopolized. Large companies hold the majority of user data (consumer data, geographical information, etc.), using it for marketing to extract value from users. However, they don't share data with other companies to maintain their competitive edge and avoid competition with smaller entities. This monopoly leads to fragmented identities of users on the web2 internet. Although web3 provides us with public, trustworthy blockchain data, these are scattered across various wallet addresses, almost unrelated, and there's no way to link users' off-chain actions (like on Twitter, Discord, etc.) to their wallets. This presents significant challenges for web3 in marketing, user analysis, and community operations. Current market tools analyze single wallet addresses, but these carry minimal user behavior data, rendering the analysis meaningless.

Alongside data monopoly, there's an increasing problem of data misuse. Content platforms and social media trade free content for user attention and data value, often without users' consent. Large companies profit enormously from this (e.g., Twitter's annual advertising and data licensing revenue exceeds $4B). However, content services don't necessarily need to be tied to data/attention value. If users could control their data value, it would allow them to manage their data and prevent privacy leaks.

Data2.cash allows individuals to aggregate web2 and web3 data, creating anonymous profiles on the blockchain using zero-knowledge proofs, selling the rights to use their data while maintaining privacy. Data2.cash supports multiple uses of user data, with the first application being a precise marketing platform. Web3 projects can select desired tags and send specific promotions to users via email/Telegram, etc. Users receive cashback for providing their data when they receive these offers.

Personal Data Vault(PDV): Users can import their web2 and web3 accounts into a personal data vault, generate zero-knowledge proof tags, and link these tags to a public account. Users can create an anonymous profile through their PDV. They can control their data, choose which tags to show or hide, and see the earnings from each use of their data.

Data Exchange: The data exchange allows developers to pay for queries of on-chain anonymous user profiles, in a fully permissionless way. The authenticity of these tags is guaranteed by zero-knowledge proofs.

End-to-End Channel: Each anonymous profile has an end-to-end channel with its owner, meaning messages sent to the anonymous profile directly reach the owner.

Precise Advertising Platform: Connected to the data exchange, companies can customize tags for their target users in the advertiser center, find users with these tags, and distribute exclusive offers through the end-to-end channel.

• Reducing the Cost of Reaching Target Users: Compared to web2 ads and web3 task platforms, significantly lower the cost of acquiring precise users. As Data2.cash integrates web2 and web3 data, the users found are genuinely precise. Every message sent directly reaches the target users, reducing ineffective ad displays and converting the cost for ineffective ads into discounts for target users.

• Establishing Long-Term Relationships with Target Users: Advertisers no longer need to go through intermediaries (like content and task platforms) to make one-off contacts with users. Instead, they can establish long-term, direct relationships with target users.

• Understanding Target Users: Manage different types of target users based on web2 and web3 data, gain insights into user behavior preferences, and assess the impact.

• Reducing Risks, Focusing on Products: Since the data is actively provided by users and complies with regulations such as GDPR, this eliminates the risks associated with data management. For example: A Dex on zkSync is hosting a promotional event, offering gas refunds to a targeted audience.

• Users with more than 0.1 ETH on zkSync.

• Users who have used Uniswap over 100 times The Dex can curate two tags on Data2.cash and establish channels with these users, send them unique offers.

Through Data2.cash, individual users can obtain an anonymous profile and turn their data into an asset without compromising privacy, thereby regaining complete ownership of their data.

What makes Data2.cash special is the ability to store and trade data in a way that boosts interoperability, without sacrificing users' privacy. The data trading protocol is permissionless, meaning any developer can access user data through Data2.cash's API, developing user-centric(instead of addresscentric) products. For instance, attribution analysis platforms can use this protocol for more accurate statistics; content platforms can match content based on user preferences, even if it's the user's first visit to the platform.
