  • How for example can I verify a transaction if it's hashed? @Erik Funkenbusch Commented Jul 5, 2017 at 8:39
  • As I understand, we use hashing for indexing purposes. Hash of transaction is just an ID used an index for locating the complete transaction. Commented Jul 5, 2017 at 8:49
  • @sanket1729 - hashing can be used for many purposes. For example, they are often used in Proof of Work algorithms. However, blockchains explicitly use hashing to cryptographically sign each entry, not for indexing purposes (although they can also be used for indexing, that's not its main purpose).

  • @adameliezerov - you don't verify it, generally, unless you're planning to write your own wallet software. You can use tools like chain explorers and the like to find transactions. But you have to get pretty low level to validate the hashing yourself. If that's what you want to do, then I strongly suggest getting any of the numerous blockchain books out there.

  • I understand the uses of hashing. I meant specific to the case of transactions. It is just an unique identifier used for indexing. Commented Jul 5, 2017 at 13:24
