Brief Description: The total count of unspent transaction outputs (UTXOs).
The UTXO_Total_N has multiple versions:
- _total_n: all UTXOs, but excluding coins with dust value (<546 sats)
- _total_n_incl_dust: all UTXOs, including coins with dust value (<546 sats)
- _total_n_lth: all UTXOs aged more than 155 days
- _total_n_sth: all UTXOs aged less then 155 days
Interpretation From a network perspective, the UTXO_Total_N is important because every node needs to maintain a database. A growing UTXO_Total_N indicates a more complex database.
Advanced Explanation Every bitcoin node has a database of all UTXOs that could potentially be spent. If one try to spend bitcoin (UTXO), the node essentially checks if this UTXO exist in the database - before checking the key validity.
