Our API software is designed to be easily integrated with existing wallets, exchanges, webapps, and DeFi platforms. The API serves data from the Bitcoin Core (BTC) blockchain. The API allows a user to identify which coins have been certified by Bitroots. These coins are either: 1. Freshly minted coinbase outputs that have been produced by certified miners. 2. UTXOs that have been traded on the ledger but have originated from a certified coinbase output. At present, the API only supports certified UTXOs that have come from a chain of one-input one-output transactions since coinbase.
