can u please tell me can i send a fake bitcoin transaction if its possible how it works ?
i am using this information for school project

Blockchain is an open ledger and once a transaction will be broadcasted then you can not reverse it. So, to answer your question, you can not fake a bitcoin transaction.

It is pretty obvious that this is not for school project because you can sure send BTC to any schoolmate you got then why make a fake transaction just to be presented into the class, Your professor obviously is against Bitcoin if that's the case, I don't really want to judge you for being a brand new rank but what is your real purpose behind this?

But well if you are making a fake transaction that for me I think you can never do it, they might as well send it to a fake wallet because it will surely be recorded on the blockchain but expect your BTC long gone into the abyss.

what about making a transaction that will appear then will never be confirmed

You wouldn't be asking this question on this forum if it was possible. It wouldn't exist any more as no one would trust Bitcoin any more.

The prime reason it took off in the first place is the way it managed to completely extinguish all doubt about the validity of a transaction. Without that Bitcoin has zero value.

A 'fake' transaction cannot be broadcast, let alone mined and would never reach another wallet nor would it be sendable in the first place. Every aspect of Bitcoin's design squashes the possibility flat.


You'll just be ignored completely. It will never appear anywhere.

It isn't possible to make a fake transaction in bitcoin. If such possibility is available, more scams and fraud activities could be found with bitcoin. Also this will serve as a negative thing for the bitcoin usage on the services and on other needs where bitcoin acceptance is encouraged.

You can't because the other nodes will reject it. And there are so many of them... Which is why other altcoins with fewer nodes are more prone to fail. If you have ever heard of the 51% attack, it means you need to have more than half the nodes worldwide for them to validate your fake transaction. Again, Bitcoin having the most nodes than any other, is the strongest in this.

A valid transaction needs to fit, its like trying a key in the wrong keyhole, the fake one won't ever fit. Furthermore, after that key fits, the next one goes connected to yours, which has to fit as well. They all form a chain... the famous blockchain. New transactions go on top of the chain, and all of them behind fit to each other. This also ensures they can never be altered, attempt to change one and the whole thing becomes invalid, and rejected by the nodes. So your transactions remain in there forever, and nobody can alter them afterwards (no erasing, covering tracks, or manipulating of any kind).

Transactions might be delayed of being confirmed but it's impossible that you can create a transaction that will never be confirmed.

Even the TX's that has lowest fee, they get confirmed.

You cannot send fake transactions in bitcoin, and if it was possible then I'm sure a lot of people would be doing that to scam others. While you may not be able to perpetrate with what you are thinking, one can still produce a 'fake' transaction by redirecting the same tx into some other address. Technically, if a transaction is not yet confirmed, there is still a possibility that it can be sent out to another address, so one can still provide a broadcasted, initial txid to someone and while the transaction is being replaced by the sender. This can be done if the tx has an ultra low fee paid for which, obviously would take longer than usual to get confirmed and just replace it with a higher fee to another address and there you go, you just created a 'fake' (not really) transaction.

No it is not possible. Not sure what you mean by fake  bitcoin transaction. Well, any kind of fake bitcoin transaction will be automatically rejected from the network. You can double spend your bitcoin by making a transaction with extremely low fee and another transaction (by referring to the same unspent transaction output) to yourself.

There is nothing like fake transaction in bitcoin but people might fake you about the bitcoin in so many ways. If you are supposed to get bitcoin from someone than better wait for the transaction to be confirmed before paying him as they can do so called "double spending".

There are also so many guides available online for your research, just make a google search.

Every of your transactions has to be verified on the bitcoin network runned on blockchain otherwise the transaction is useless. Even a case of double spending can't even happen as one will be rejected. Blockchain transactions can't be adulterated by anyone.

 ;D fraud is not allowed with decentralized platform, so, try again next time with another tactics. My Candid advise for you is just quite scam attempt if your intention are for you to scam people. Transactions in Bitcoin cannot be fake and cannot be reverse whatever, so keep off this attempt.

With RBF you could do a fake transaction because you're going to double spend but it's only temporary.

One of the two transactions will be removed eventually once the other transaction with the higher fee gets a confirmation.

If a transaction doesn't confirm for a long time it could get rejected and the bitcoins are returned to the sender.

What you are trying to do is make a double spend. You can do this by making a first transaction with zero fees. This will not be confirmed easily. Then you make another transaction with fees so that it will be confirmed faster than the first tx making the first invalid tx. Bitcoin is protected by this by waiting for a confirmation first.If you accept payments without confirmation, you are vulnerable to double spending.

You can't. Good luck with your project btw!

Bitcoin is so transparent, you can send fake transaction to it, regardless of the amount, all you send will be registered in the blockchain.
You cannot fake a decentralized system, if you want to experiment, try a centralized one.

In case the transaction which will never be confirmed..but I bet it makes no sense.

Yeah you can create your own site and show all the fake address transactions there which is happening in the market especially those who are trying to scam people. Those who said they receive 4ETH after sending 2ETH are totally scam and they are showing some transactions on that, well its fake of course. You better to be good on IT on creating your own site but if its a school project then it must not be complicated like this. You can't make transactions like this, its not possible or else create your own address and make transactions between those addresses.

He obviously doesn't know how the Bitcoin protocol works...

I think he is simply want to know how to create one for him to scam others, I don't think creating a fake transaction can be a kind of school project, that just make me laugh,
anyway I think the reason why the OP is newbie is for him to not get detected for the scam we wanted to do, I think he want to create a fake transaction for the purpose that he send something to someone and post it in the social media so he can attract victim.

you think it doesnt makes sense to you but it does makes sense to some because they intend to spam the network with lower fees  . they are bitcoin haters and they nothing to do with thier lives  .

@fake transactions ? you mean sending to an unknown address ? with a low amount and with lower fees ?  yes its possible  but like the guy above said  , the transactions might never be confirmed forever .

The correct answer is NO, but some people create their own so-called Crypto currency investment site and then they connect that site with their own internal ledger with fake coin tokens. <Not tokens on the Blockchain> The investors are oblivious to the difference, so they think they are buying actual coins.

Usually these sites do not allow people to withdraw actual coins, but you can sell your fake tokens and withdraw the cash. They charge trading fees, when you sell fake tokens on their internal ledger as if you were buying and selling real Crypto currencies.  >:(

Some scam sites like btc doublers fake transactions but they are only visual they don't work if you click them. Another way is to make a fake blockchain and then the transactions lead to that blockchain which you control.
It doesn't really mean it is fake. It is real blockchain but isn't being used.


Good answer. Then they fake volume to fool people.

You cannot send a "fake" Bitcoin transaction that you have. Majority of the network runs the reference client which also follows the protocol rules. With that in mind, the nodes will reject and refuse to propagate any transaction that doesn't follow its rules. The main rules is that the transaction must have a valid signature which would provide the proof that the UTXOs are authorised to be spent. In addition, its also not possible to fabricate a transaction with fake inputs since the inputs must be in the UTXO list of the individual nodes.

Fake transactions no ways!

This is not fiat were we have problems of counterfeit notes and the alike.

With cryptocurrencies anything fake coins means altcoins and bitcoin BTC is the only coin which is not an alt, so to have fake transactions that would mean having another blockchain.

Really? How can one send fake transactions to bitcoin?

No of course because everything you do in blockchain will be immediately registered and saved...can i know how your project work for more clarification ??

Fake is a loose word, and under some definitions fake transactions can be possible. Double-spending can be considered one such example - there are multiple ways to do it. The first type is unconfirmed transactions - like their name suggests, they are not final, and scammers can trick unexperienced people into accepting them, and then abandoning those transactions by making competing transactions that spend the same coins get accepted in the block. The other type is a double-spend attack with chain reorg - this reverses all latest transactions, even if they are included in blocks, but to this day this attack remained theoretical in Bitcoin (but not altcoins), because Bitcoin is protected by PoW.

That is one good reason of why blockchain technology exist because it cannot be manipulated, all transaction are real and recorded on a ledger and systematically encrypted for security.

Of course that is impossible, bitcoin uses blockchain, and the blockchain is the biggest journal that anyone can see. So how can you do a fake transaction.

I don't understand why most people said 'No', because it's wrong.
You can actually send fake transactions. OP didn't ask if a fake transaction would be accepted by the network, which of course will have the correct answer 'No'.
