# Ola Introduction

Ola is a decentralized infrastructure focused on **security, earning, and interoperability** within the Bitcoin and broader multi-chain ecosystem, unlocking the potential of $1.5 trillion worth of assets in BTC. As a **Decentralized Security Provider**, Ola enhances the security and data integrity of Bitcoin-based projects through decentralized Zero-Knowledge Proof (ZKP) verification, offering **trust-minimized cross-chain interactions** that elevate Bitcoin’s potential across different blockchains.

Ola’s two primary products—[**Massive**](https://olavm.org/massive) and **Onis**—work together to unlock a variety of earning and network participation opportunities:

* [**Massive**:](https://olavm.org/massive) A decentralized **mobile ZKP verification network** that allows users to verify blockchain transactions using their smartphones. By doing so, they not only secure the Bitcoin ecosystem but also earn **multi-stream rewards**. Beyond verification, Massive also operates as a **BVM Challenger** (BitVM) and performs **Data Access Sampling** (DAS), where users monitor data availability and ensure the reliability of projects. Through these activities, users help increase the efficiency and security of Bitcoin projects while benefiting from sustainable, token-based rewards.
* **Onis**: A **trustless light client** that facilitates **cross-chain interactions** by leveraging zero-knowledge proofs. Onis acts as the infrastructure enabling connectivity and interoperability between Bitcoin and other blockchains, ensuring seamless and secure data communication. This opens new doors for users to engage in **DeFi, cross-chain asset management, NFTs**, and more — all without the need for centralized intermediaries.
