The development of blockchain technology has brought about a large amount of data, but currently, there are still barriers to data interaction between various Rollups. This data isolation has resulted in significant value wastage. However, Caldera's Metalayer project is breaking this situation by implementing an innovative cross-chain data protocol that realizes true data sharing and value creation.

The core advantage of Caldera lies in its concept of a decentralized database. It first standardizes data by unifying the transaction formats and user tags of different Rollups, enabling developers to easily access user information across the entire ecosystem. This functionality greatly enhances the precision marketing effectiveness of applications such as DeFi projects.

At the same time, Caldera also focuses on user privacy protection. Its querying system only returns statistical results and does not disclose personal information, providing a safe and reliable data source for data analysis agencies. In addition, Caldera has established an incentive mechanism to encourage Rollups to provide data and requires developers who use the data to pay with ERA tokens, forming a positive data value cycle.

This innovative data-sharing model has demonstrated tremendous potential in various fields. For example, a certain prediction market trained AI models using comprehensive trading data from the entire ecosystem, significantly improving prediction accuracy. Another case involves a DAO organization that successfully optimized governance proposals by analyzing cross-chain voting records, greatly increasing participation rates.

In the Caldera ecosystem, the ERA token plays the role of "data currency." It is not only used for settlement of data queries, analysis, and sharing, but holders can also participate in decision-making, such as determining the types of data that can be shared and the distribution of profits.

Caldera's innovation is redefining the value of blockchain. It proves that the importance of blockchain is not only reflected in asset management but also in the flow and reuse of data. With the promotion of this data-sharing model, we have reason to expect that the blockchain ecosystem will usher in a more prosperous and efficient development.
