Title: Can coinbase transaction contains multiple destinations? Post by: hushan on April 23, 2018, 12:31:37 AM Can coinbase transaction contains multiple destinations, or does it have to be one output? For example, for the current reward 12.5, if set the coinbase tx to send 10 to one address and 2.5 to another, is it a valid coinbase tx and will it get confirmed by the network?

Yes, you can have a coinbase transaction with multiple outputs. The sum of the outputs just needs to be less than the block reward (block subsidy plus transaction fees).Title: Re: Can coinbase transaction contains multiple destinations?

Yes, you can have a coinbase transaction with multiple outputs. The sum of the outputs just needs to be less than the block reward (block subsidy plus transaction fees).But in reality almost all miner set the outputs (plus fees) is equal with block reward & tx fee ::) Also, if OP is interested in technical details, you can see more info at https://www.safaribooksonline.com/library/view/mastering-bitcoin/9781491902639/ch08.html (https://www.safaribooksonline.com/library/view/mastering-bitcoin/9781491902639/ch08.html). It's a bit outdated though. Title: Re: Can coinbase transaction contains multiple destinations?
