Title: A few questions about bitcoin transactions Post by: IanQuinn on May 15, 2016, 11:47:57 PM Are bitcoin transactions guaranteed unique?
Can they be manipulated? Can you determine in advance a transaction Id? Been reading bitcoinwiki on Transaction, but could not find the answer we are looking for. With the extensive knowledge base here on this forum, these should be simple questions. If there are better documents to view, this would be helpful also.

Each transaction references an output of another transaction, and that output is unique.Can they be manipulated? Manipulated in what way? You can add arbitrary data into a transaction.Can you determine in advance a transaction Id? Usually no.

We are trying to use transaction id as an RNG, from funds sent. So want to know if someone can manipulated the results of a transaction.

Yes, it most certainly can be manipulated, it is just slightly difficult to do.We are trying to use transaction id as an RNG, from funds sent.
