utxo

Example

let utxo = require('utxo')
let transactions = {
	"2c20ca6ca3a2af32d3ca0c6c1a60f6d3c00101342620a21f3622fc6faf2ddcda": {
		"inputs": [
			{
				"txId": "xxx ...",
				"vout": 0
			},
			{
				"txId": "xxx ...",
				"vout": 1
			}
		],
		"outputs": [
			{ "script": "..." }
		]
	},
	"bdcdd2fafa1c6c0ac3d23fa2a3ac66cf2263f12a03444310100c3d6c06ac02c3": {

				"vout": 0
			},
			...
		],
		// and so on
	}
}

// equates all transaction outputs for where no matching input exists
// subsequent double spends are ignored in the returned result, with priority given to first-seen
// txId and vout is extended onto the outputs for convenience (outputs are copied, not mutated)
let unspents = utxo(transactions)
