1I'd refrain from using the term "sidechain" because that has a special meaning which is not equivalent to competing chain tip, or "forkchain". You have an empty line in the inputs list, and extraneous space after "( " in the second to last line. Coinbase input coin is smaller or equal to reward and fees; you don't have to claim all of it for the coinbase to be valid. However, I don't think that your question works well on our platform, we work well for answering specific questions. Other mediums are better suited for open-ended requests for feedback or collaborative development. – Murch – 2015-09-17T11:28:19.953

Nice work though. :) – Murch – 2015-09-17T11:28:34.777

fixed Coinbase fees constraint. Thank you. What is the correct term for mainchain branch you can offer? – bitaps.com – 2015-09-17T11:46:09.247

1I'd call it the "best chain", but I've seen other names for it such as "main chain", "canonical chain", "primary chain", and "longest chain". The other chain branch I'd call "shorter fork", or "stale fork" once it has been obsoleted. As long as both tips are at the same height, they are just two "forks", because it is unclear which one will succeed, but you can name them for recognition of course. – Murch – 2015-09-17T11:53:34.917

You would probably get more out of it, if you posted it to reddit or bitcointalk and asked for feedback. Those platforms are more suited for such a topic. – Murch – 2015-09-17T12:07:55.377
