# 5.2 Summary The HNDL project is a comprehensive decentralized naming system built on the Rootstock Sidechain and Ordinals, leveraging the Ethereum Virtual Machine (EVM) on Bitcoin to provide unique handles for individuals. These handles, represented as non-fungible tokens (NFTs), enable users to establish their digital identities, manage personal branding, and interact seamlessly within the Web3 ecosystem. Key features include handle registration, sub-handle minting, renewal and burning mechanisms, public and private data storage, and sign-in protocols. The system also integrates Token Bound Accounts (ERC-6551) to link handles to Rootstock and Bitcoin addresses, facilitating secure management of assets. The system has limitations such as character restrictions and handle registration periods. Risks include the need for users to monitor expiration dates to prevent asset loss. The project's roadmap outlines a phased approach to development, including the integration with Web 2 & 3 ecosystems, achieving full decentralization, and the development of an HNDL wallet. Overall, the HNDL project aims to provide users with a robust, decentralized naming system that enhances identity management, security, and interoperability within the blockchain space. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
