# App Chain & Layer 3 by Mode & Base By [Nataliiiiii](https://paragraph.com/@iamcryptogirl) · 2024-03-05 --- Have you ever heard of the **Layer 3**? And no, it's not about everyone's favorite quest platform, it’s about additional protocol layer in blockchain technology built on top of Layer 2. ![](https://storage.googleapis.com/papyrus_images/c8f2ed992babe88f9187e73df1a0781fbaadd32b99435948d621a5686c41c755.png) In the realm of cryptocurrencies and blockchain technology, constant evolution is underway. One of the latest developments capturing the community's attention is the concept of Layer 3, which adds another layer of functionality to existing Layer 1 (core blockchains) and Layer 2 (smart contracts and scalability). ### **What is Layer 3?** Layer 3 is an additional protocol layer in blockchain technology built on top of Layer 2, offering higher-level functions and capabilities. This layer may include various protocols and solutions such as data coordination mechanisms, resource management, and smart contracts designed to deliver more complex and flexible services. ### **Why is Layer 3 used?** 1. **Enhanced Scalability:** Layer 3 can offer new mechanisms to improve network performance and scalability. This may include optimizing resource usage, more efficient transaction management, and data compression. 2. **Functionality Expansion:** Layer 3 enables the addition of more complex features and capabilities that cannot be achieved at lower protocol levels. This can include smart contracts, additional security mechanisms, and capabilities for decentralized applications. 3. **Improved Privacy and Confidentiality:** Layer 3 can provide enhanced data privacy and confidentiality mechanisms, ensuring a more secure environment for users and enterprises. 4. **Flexibility and Extensibility:** Since Layer 3 is built on top of lower protocol layers, it can be more flexible and easily extensible, allowing the network to adapt to various needs and conditions. 5. **Reducing fees** So Layer 3 represents an exciting step in the evolution of blockchain technology, providing new opportunities and functionalities to enhance performance, flexibility, and privacy. It opens the door to creating even more innovative and efficient systems that can change the way we interact with the digital world. And on February 21, the launch of [**Mode Flare L3s**](https://www.mode.network/mode-flare-l3) was announced. ![https://twitter.com/modenetwork/status/1760373387732349143](https://storage.googleapis.com/papyrus_images/0abfeb2a28dcf6dba9d1035076fd5970db7bca032bb1a8243c9ba7a63f385ce9.png) https://twitter.com/modenetwork/status/1760373387732349143 ### **What is Mode Flare L3s?** It is Layer 3 network powered by Optimism (OP Stack) and Celestia as the Data Availability layer for unmatched performance.
