SDK Design Philosophy
This document details the core principles behind the BSV TypeScript SDK architecture and design decisions.
Zero Dependencies
The SDK is built without external dependencies to:
- Minimize security attack surface
- Reduce bundle size and complexity
- Ensure long-term stability
- Provide predictable behavior
SPV-First Approach
The SDK prioritizes Simplified Payment Verification:
- Lightweight: No need to download the full blockchain
- Efficient: Verify transactions using merkle proofs
- Scalable: Works with millions of transactions
- Secure: Cryptographically verifiable without full nodes
Vendor Neutrality
The SDK works with any compliant Bitcoin infrastructure:
- Wallet Agnostic: Supports any BRC-100 compliant wallet
- Network Flexible: Works with different chain tracking services
- Service Independent: No lock-in to specific providers
Modular Design
Components are designed to work independently:
- Composable: Mix and match functionality as needed
- Extensible: Easy to add custom implementations
- Testable: Each component can be tested in isolation
- Maintainable: Clear separation of concerns
TypeScript-First
Built specifically for TypeScript to provide:
- Type Safety: Catch errors at compile time
- Developer Experience: Rich IDE support and autocomplete
- Documentation: Types serve as living documentation
- Reliability: Reduced runtime errors
Security by Design
Security considerations are built into every component:
- Cryptographic Primitives: Secure implementations of Bitcoin cryptography
- Input Validation: All inputs are validated and sanitized
- Error Handling: Comprehensive error handling prevents information leakage
- Best Practices: Follows established security patterns
Optimized for real-world application needs:
- Memory Efficient: Minimal memory footprint
- Fast Execution: Optimized critical paths
- Batch Processing: Support for high-throughput scenarios
- Caching: Intelligent caching where appropriate
Developer-Friendly
Designed to make Bitcoin development accessible:
- Clear APIs: Intuitive method names and parameters
- Comprehensive Documentation: Tutorials, guides, and references
- Working Examples: Real code that developers can use immediately
- Progressive Complexity: Start simple, add complexity as needed
