# Web and Mobile Applications

Modern decentralized applications (dApps) frequently rely on RPC endpoints to retrieve blockchain state and transaction data. While this approach simplifies development, it introduces a trust assumption that contradicts the principles of decentralization. A stateless client provides a trustless alternative by enabling applications to fetch blockchain data from any provider while independently verifying its authenticity.

* **Trustless Data Access**—Applications no longer need to trust centralized RPC services; they can verify blockchain state cryptographically.
* **Efficient Verification**—Stateless clients reduce the need for heavy computation or storage on mobile devices and web browsers.
* **Immediate Usability**—Unlike full nodes or traditional light clients, stateless clients do not require lengthy synchronization before providing verifiable blockchain data.

This approach is particularly relevant for financial dApps, on-chain identity verification, and Web3-based authentication mechanisms, where security and trustlessness are crucial.
