Title: newbie question txid
Post by: forestx on May 29, 2020, 02:37:03 PM
Hi
I sent some coins over from coinbase to another wallet but I need the txid for it. The transaction is still spening. I have googled this but slightly confused
1st is the txid the same as hash number or where on this page (example) is the txid

bitly 2XiaiRb

Thanks

Yes, the hash is the transaction id.
In your case: 9f91659f58998d442d36a1c8e37e88319a3ca410af87a4f554e28b56fde34e16.

The transaction is already confirmed, so i guess your problem is solved now anyway?

The name usually varies but it means the same thing... Transaction Hash/Transaction Hash ID (Tx Hash ID)/ Transaction ID(TXID)/Transaction Hash

Just to help you understand the meaning;
Quote
Tx Hash means Transaction Hash and is also known as Transaction ID (TxID). It consists of alphanumeric characters and is basically an identification number given for a Bitcoin transaction. Each and every single transaction that is conducted on the Bitcoin blockchain has this unique identifier. Similarly, transactions on Ethereum blockchain will have a unique Tx hash and every transaction on Litecoin blockchain will also have a TxID

This unique identifier is a long string of letters and numbers that is used to identify a specific transaction on the blockchain

That can be true for legacy transactions because TXID and TX Hash will be the same.

But for Transactions with SegWit data, the "Transaction Hash" will be different than the "Transaction ID".
In "SegWit Transactions", Witness data won't be included when computing the TXID, but all will be included for the HASH; so the two can't be used as the same term.

Read this if I didn't explained it well: https://bitcointalk.org/index.php?topic=5189731.msg52639722#msg52639722 (https://bitcointalk.org/index.php?topic=5189731.msg52639722#msg52639722)

But since OP is talking about a certain (non-SegWit-friendly) blockexplorer's data named "hash", yes it's the TXID  :-\
Just mentioned so users wont confuse TXID and HASH when they call decoderawtransaction or a json data from a transaction.
