transaction hash

[thomas.yayo]

I was asked to give a transaction hash but I have no idea what it is and where to find out.
Can anyone help? Thanks in advance.

What type of wallet are you using?

The transaction hash is commonly called the transaction ID, or TXID. Depending on what you use, you can find it.

For example:

https://blockchain.info/tx/e2505d4b1e71f221f06f34912ca5fb22f5623de613362b0f1c8fcd1d7dfbc39c

The transaction ID here is found after "tx" in the address. The frontpage of blockchain.info is covered in transactions.

I hope this helps!

Easy way to look it up is to use a block explorer like blockchain.info, as mentioned above, and look up one of the sending/receiving addresses that you know are part of the transaction.

I assume you have the address you sent your bitcoin to.
Go to blockchain.info, search for that address, and find the transaction you made.
The long string you find above the transaction is the Tx ID.

Why were you asked for a transaction hash? You should know that ordinary users have no need for that information, and it's only useful in very specific situations, such as investigating why a transaction failed. If you are asked for a transaction hash for any other reason, the person asking is probably doing something wrong.

Maybe OP sent bitcoin to a wrong address, and is now asking the receiver to kindly send the bitcoin back?

Exactly. It's just a thing to look up the transaction on the blockchain... I always provide transaction IDs when I buy things from people. It's like a receipt.

I think that a transaction hash is just useful in general because it's just regularly used to refer to a certain transaction, rather than telling somebody that "Oh I'm talking about this transaction from this address to this address at this time"

It's better and easier, since by looking up the tx on blockchain it shows everything, timestamp, confirmations, from, to, etc.
There's nothing wrong about that.

+1.
Instead of telling the other person "Hey I have sent you 1 BTC from my address 1ABC to your address 1XYZ yesterday 3PM UTC", you could just give him the tx id.
Plain and simple.

No, it isn't. A receipt is something that the receiver of something has, and nobody else has. Transaction hashes are public record. Anybody in the world can look up anybody else's transaction and claim it as their own. Knowing a transaction hash does not prove you sent or received it, and anyone who assumes it does is not just mistaken, but criminally incompetent. Transaction IDs identify transactions, not people, and should never be used for any other purpose.

Thanks a lot for all your answers.
I'm using a wallet provided by localbitcoins but I don't know where to look up the hash.
Moreover, I tried to search it on blockchain by typing in the address but it didn't work.
Any ideas? I'm thankful for everything.

You still haven't explained why you want it, but localbitcoins doesn't make it very easy to find the transactionID (transaction hash).  This is because localbitcoins is not a wallet, but instead is an account.  The wallet is controlled by localbitcoins, so you don't have access to much of the information, and they have the ability to handle the transactions however they like.

The easiest way to find the transactionID will  probably be to search the blockchain for the address that you sent the bitcoins to.  Then look through the list of transactions that were received at that address at approximately the time that you sent your transaction.  You should be able to find a transaction that transferred the exact amount that you sent.

If you send me the address that the bitcoins were sent to, the approximate date and time (and timezone) that you sent the transaction, and the exact amount that you sent, then I should be able to look it up for you and provide you the transaction hash.  I'll even send over step-by-step instructions on how I found it so you can better understand the process.

And also, coins are probably mixed on localbitcoins, so even if your "Account" has 0.01BTC, you won't see that 0.01BTC on a block explorer.

Which is why I asked for the address that he sent to, and the amount that he sent (instead of asking for his address and his current balance).
