UTXO: Unspent Transaction-Out. Those are the important parts of the blockchain that indicate coins that are currently held by a given address. Spent transaction-outs maintain the history of those "active" coins.
In browsing some of the development posts I repeatedly come across these acronyms, but I haven't seen any definitions either here or on the wiki. I gather that UTXO means something like the total blockchain. Does anyone know what these acronyms stand for?
