Arcblock is a platform designed to improve the process of developing and deploying decentralized blockchain applications. It is a solution that combines blockchain technology with Cloud Computing. Arcblock is a marketplace for reusable services, components, and even applications. The ABT ERC-20 token is used within the Arcblock ecosystem. The platform is not just a software package or set of APIs, but a self-evolving ecosystem. Arcblock strives to provide an enhanced user experience and protocol-agnostic platform.

Arcblock operates through a design known as Blocklet, an application protocol that can be implemented with any platform or language. Blocklet connects to any existing data source and performs both on-chain and off-chain computing. It communicates with the blockchain under layer through the Open Chain Access Protocol, allowing the application to access external data securely while also maintaining data integrity. Arcblock also introduces the Open Chain Access Protocol, which enables open connectivity over multiple blockchain protocols, giving developers the freedom to evaluate and switch between different blockchain protocols.

Arcblock has a wide range of potential use cases. It can be used to build and deploy decentralized blockchain applications, making it easier for developers to create applications that can handle a large number of concurrent users. Arcblock can also be used to develop off-chain logic, handle assets and resources, implement smart contracts, and act as a bridge that connects on-chain and off-chain logic. Furthermore, Arcblock can be used to create a marketplace for reusable services, components, and applications, encouraging the blockchain community to work together to build a better ecosystem.

Arcblock was developed to address the challenges facing current blockchain technology, such as performance, user experience ,cost of use, and platform lock-in. The platform was designed using a "top-down" strategy that centers on the user experience, in contrast to many existing solutions that focus on the blockchain technology itself. Arcblock was built with an open standard, with the core components being open-sourced and the team members actively involved with a range of standards organizations, non-profit foundations, and committees. The platform continues to evolve and grow on its own, driven by the contributions of the Arcblock community.
