- How for example can I verify a transaction if it's hashed? @Erik Funkenbuschadam eliezerov– adam eliezerov2017-07-05 08:39:14 +00:00Commented 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.sanket1729– sanket17292017-07-05 08:49:49 +00:00Commented 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).Mr.Nobody– Mr.Nobody2017-07-05 10:41:48 +00:00Commented Jul 5, 2017 at 10:41
- @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.Mr.Nobody– Mr.Nobody2017-07-05 10:44:15 +00:00Commented Jul 5, 2017 at 10:44
- I understand the uses of hashing. I meant specific to the case of transactions. It is just an unique identifier used for indexing.sanket1729– sanket17292017-07-05 13:24:41 +00:00Commented Jul 5, 2017 at 13:24

- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. bitcoin-core), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
