# Web5 Implementation [AIR-3][AIS-3][BPC-3][W5C-3][DID-3]
This directory contains the Web5 implementation for Anya Core, following official Bitcoin Improvement Proposals (BIPs) standards.
## Overview
The Web5 implementation provides a comprehensive integration with the Web5 protocol, supporting Decentralized Web Nodes (DWN), Decentralized Identifiers (DID), and verifiable credentials.
## Architecture
The implementation follows a layered architecture with:
- **DWN Layer**: Decentralized Web Node implementation
- **DID Layer**: Decentralized Identity implementation
- **Protocol Layer**: Web5 protocol implementation
- **Bitcoin Integration**: Integration with Bitcoin and Taproot
## Key Components
