Title: Stuck, trying RBF/double-spend, blockchain explorers not showing newer tx??
Post by: wckoce03_ec on December 19, 2017, 12:25:34 PM
So, I'm using the bitcoin core wallet (linux, version 0.14.1, 64bit) and followed the instructions in the first post in this (https://bitcointalk.org/index.php?topic=1802212.0) thread. I abandoned my first transaction (had to delete mempool.dat and restart core with -walletbroadcast=0 to be able to do it) and then made another send attempt... here goes:

First transaction still visible on blockchain.info:
https://blockchain.info/tx/ddfd5d8e0590e6d043d334c5b881f784e411c338354930476aa6901ec9ee942d
==> found, unconfirmed

Second transaction not found on blockchain.info:
https://blockchain.info/tx/1d83e0833398f6f54cc1eae90c45fc2395992fb77ccb5c450895bc5f0707ff79
==> transaction not found!

Yet, the bitcoin-qt says the second transaction is in memory pool and the first is not... And my balance shows up correctly according to spending only the second transaction. What gives? It's not "help" I want but to understand what's going on?

Here are what the Bitcoin Core is telling me as details for these transactions:

This does not show up in blockchain.info:
=============
Status: 0/unconfirmed, in memory pool
Date: 18.12.2017 17:34

This shows up in blockhain.info:
=============

Transaction total size: 226 bytes
Output index: 0
=============


Should I expect the second transaction to show up on blockexplorer on blockchain at some point?
Can I expect it to actually get confirmed? Both of these transactions are not going to get through, right? RIGHT? I do have balance for both of them, but I kinda wish to keep my locally held balance over 1 BTC... Also, it's a exhange account deposit address, so even if they both go through I shouldn't be actually losing other than the transaction fees...

Do double-spend transactions get relayed in network normally? Does it matter if I keep my own Bitcoin Core client/wallet running?

Looking at this page, the 0.00226 BTC transaction fee (that I set for the newer transaction) is more than double the median fee for quick transaction...:

Thanks for helping me understand the picture here. Technical explanations welcome too.

Hi,

I have NO idea what has happened, but my problem has been solved now.

It seemed like someone was rebroadcasting that first low-fee transaction, since blockchair said it's time was 29th Dec. instead of 14th (while the later, higher-fee was nowhere to be found.

Now, somehow, the first is missing and second is going/has gone through with 4 confirmations at the time. So, I guess I'm happy now but really, I'd like to understand where that 29th Dec time came, and is there a way to inform the network that "please do not rebroadcast this"?

The time that the node has received/seen that transaction.

and is there a way to inform the network that "please do not rebroadcast this"?
No.

FYI, you overpaid by at least 2x in your RBF.
