UTXO (Unspent Transaction Output)
UTXO (Unspent Transaction Output), a record of unspent Bitcoin used for on-chain analysis to track fund flows, ownership patterns, and network activity.
What is UTXO?
A UTXO (Unspent Transaction Output) is a discrete unit of Bitcoin, a digital asset, received from a transaction and available for spending, identified by a transaction ID (TxID) and output index, linked to a specific address. Each UTXO contains an amount (e.g., 0.5 BTC) and a locking script (governed by BIP-16 for P2SH or BIP-141 for SegWit), which defines spending conditions, enabling analysts to map transaction flows with precision.
In on-chain analysis, UTXOs are critical for tracing the movement, ownership, and behavior of Bitcoin across the blockchain. For on-chain analysis, UTXOs reveal spending patterns, wallet clustering, and economic activity.
