# Realization of Blockchain and Data Economy

Agendabook is a representative real-use service of the BaaSid project, a next-generation survey and voting platform that combines user experience (UX) based on blockchain technology, DX (Digital Transformation), and AX (AI Transformation). To solve the reliability and transparency problems of existing data collection services, this platform introduces blockchain-based data verification technology and provides substantial rewards to participants, thereby building a more reliable data ecosystem.

## Structure of Survey/Voting Platform

#### Blockchain-based Data Verification and Reward System

Utilizing BaaSid's blockchain infrastructure, all voting and survey data participated by users (panels) are safely managed. Response data submitted by users is processed through the following procedures:

* Response data → Hash processing → Merkle Tree structure generation
* Store Merkle Root hash value in Ethereum smart contract
* Through this, anyone can verify that the data has not been forged

Thanks to this structure, all survey data is transparently recorded and preserved on the blockchain. Users (panels) receive points for such participation, and these points are exchanged for ERC-20 based BAAS tokens to be used as practical reward means.
