You can re-broadcast in 2 ways

• 1. Re-broadcast by paying

Using :
- BTC.com Transaction Accelerator
- Louis’s accelerating services
- BLOCKCHAIN.INFO

• 2. Doing Manually

I did once doing re-broadcast using blockchain.info services.

• How to rebroadcast an unconfirmed Bitcoin transaction ?
• HOW TO REBROADCAST A TRANSACTION ON BLOCKCHAIN.INFO

This entirely depends on the software that you are using to send/receive Bitcoin transactions because certain types of software allow you to rebroadcast the transaction within the software itself otherwise you will have to do it with third party tools. First let me tell you the reasons why you might need to rebroadcast a transaction. Simply put because you have not included the right amount of fees for it to get included in a block in the time that you want it to be confirmed which means that it will be hanging much longer than expect. A great example of this is when the spike of 2018 transactions fees actually skyrocketed for a period of time. Which meant that a lot of people were using the old transaction fees and would not have their transaction confirmed for a number of days instead of a few hours that they were previously used too. Fortunately some types of software such as Electrum uses Child pays for parent features which allow you to rebroadcast the transaction with updated fees but this needs to be enabled before the original transaction was sent. I think the latest version has this enabled by default.

If the software you are using doesn't have the option to use child pays for parent then you can do it using third party tools and possibly asking a mining service to include it within blocks they are mining. You do this by:

1. Go to blockchain.info and find your transaction.

2. Find and copy the transaction hash with the blockchain.info address (txid)

This looks like a bunch of random letters and numbers.

3. Copy the TXID into any of the following (fees may apply):

https://pool.viabtc.com/tools/txaccelerator/

There are many mining services which are offering what viabtc does and you can find them by either googling for "bitcoin transaction accelerator" or by checking the services board of this forum. These mining services are often not free to use or have a certain number of free requests per day.

Blockchain.info also offers a push transaction service but you will need the hex encoded bitcoin transaction ID instead of the plain ID.

Darn! I have been away for far too long.

Well I'm back for now, will get some Q's popping.

Question: How do you rebroadcast a transaction and why do you do it?

---

Thanks for that BitMover, I don't mind at all!!!

I'll hand out the merits soon enough.

When assembling a block, miner includes coinbase transaction, the block reward, which is currently 12.5 BTC, which should go to miner's address in case of completing the block(finding a combination, nonce + all the other info in the block, so that the hash of the block is less than or equal to the current target) faster than all other miners. Coinbase has no inputs because it's a generation transaction which creates new coins from nothing.

I will make one question. I hope pugman won't mind

Question:  what is coinbase? (Not the exchange or wallet)

Can't believe this thread died off so quickly, it was a great way for people to try and increase their knowledge whilst getting a chance to add some merit. Please re-instate.

Please bring back this contest it was fun!

What happened with this contest?

I see a question was asked two months ago and there are few answers but something happened because no award is given for the best answer and OP is not active anymore.

Will this be continued?

Such a contest could be a great source of information and an amazing education tool. I think there are many reasons to keep this contest ongoing.

sorry sir

Do I learn more about your question? because I want to increase my ranking in this forum without any problems.

once again, I am sorry

Please use text spinning tools next time while you are plagiarising some content. It is really easier to find out you have stolen these texts from websites and just posting here for merit. There is no way other than reporting you here : https://bitcointalksearch.org/topic/m.46786275
You will most probably be temp banned or permabanned sooner.

Sorry Sir, Plagiarism ruined your life 

                            From February... really?

Before critism me with plagiat...look at up comment about avalanche...all same word and i do search in google that word same with Wikipedia...and i search again with Paper research...cause i believe with word or sentence that build from someone or grup that has research about avalanche...and i give link better than Wikipedia...people can studi thiier paper research with avalanche....

Function of BIP 174 is helping to make and sign  block-to-block transaction. This is built for compatibilities client-to-client. And also make possible easier hardware wallet and offline wallet setting.

So BIP 174 is not protocol or layer 2 solution for off chain transaction but BIP 174 is a transaction format for  a transaction  that not ready to broadcast to the bitcoin network.

BIP 174 is the advancement or improvement for bitcoin technology where bitcoin can be transacted offline. This said improvement is still on development phase and not yet launched official nor can be functioned now.  A lot of people specially bitcoin enthusiast can wait to see its full functionality soon.

BIP 174 is upgrade for Bitcoin (BTC) has just been added to the official network repository (so it should in next version of bitcoin core).
Its use will take place in allowing the blockchain to support Partially Signed Bitcoin Transactions (PSBT) in the future.  If this is implemented soon (hopefully we will see it) then the implementation of this solution will enabled Bitcoin's blockchain to improve certain essential.

Interesting question!
BIP 174 is a transaction format for transactions that are not ready to be broadcast to the Bitcoin network yet. I believe it will help us to send transactions without the need of immediate Internet connection. It will help for creating and signing on chain transactions and thus boosting the business of Cold Wallet manufacturers too.

I have a question too - How is it different from Lightning network ? (I mean technically)

BIP is the Bitcoin Improvement Proposal. BIP 174 is the part of bitcoin’s official repository & he is potentially allowing the blockchain to support the famous "Partially Signed Bitcoin Transactions" (PSBT) in the future.

BIP 174 will make it possible to perform transactions offline by a standard protocol that will have the facility for signing the transactions and then connect later to upload them to the Bitcoin Network. These transactions are known as Partially Signed and whilst still in the development phase, the flexibility it will offer would be of great benefit to Bitcoin in the future.

The way I (layman) understands it, BIP 174 will allow us to transfer bitcoin from a cold wallet with a "partially signed transaction" without having to immediately upload that transaction to the bitcoin network.   Meaning we can use our (supported) cold wallet for purchases and transactions while maintaining it's security.  Transactions will be fully signed at a later time.

So, essentially it can make a cold wallet partially hot.
