Chain Tracking

Understanding how the SDK interacts with the Bitcoin network for transaction data.

Data Formats

BEEF Format

Bitcoin Extras Extension Format for efficient transaction data exchange.

Transaction Encoding

How transactions are serialized and deserialized in the SDK.

Identity and Certificates

Decentralized Identity
