How to send a fake bitcoin transaction ?

[Muhammed Zakir]

A fake transaction... If it can confirmed one day then the price of bitcoin that time should be $0. Bitcoin is valuable because it cannot be faked like fiat currency (fake banknotes).
So that's why almost all clients don't allow us to send a double spend transaction.

Double-spend transactions can be confirmed.

Fake transactions such as sending a non-existing unspent transaction output(UTXO) and sending unspent transaction outputs(UTXOs) you don't own will be rejected. Sending a big sized transaction, for example, 500KB and getting confirmation is very unlikely unless the miner who finds the next block includes that transaction. The fees you will have to spend will be very high and you will need a lot of inputs to reach that size.

Double-spend for some minutes with 0-confirmation transactions is easy and anyone can do it. I guess you can figure out how by yourself how to do it if you are as smart as your are trying to make us believe.

But all the addresses involved will have a double spend warning in blockchain.info for some time

my isea is to create a software that verify automaticly transactions without waiting for miners or nodes to do (not confirm the transaction), so i need to send a wrong transaction (every valid transaction should respect 20 rules ...) so my software should say "no it's not valid " ....

That's not how bitcoin works.  The system doesn't trust what you say.  EVERY node on the network, and nearly every wallet verifies EVERY transaction before accepting or propagating it.  So even if your software says that the transaction is "verified", the system won't believe you. Every node that you send the transaction to will immediately see that it is fake and will reject the transaction.  If they receive too many fake transactions from you, they will drop their connection to you and refuse to let you reconnect.

it's the 3rd time i say this its for research :

you need to wait about 10min to 1hour for every transaction to be confirmed,so :
my application don't confirm the transaction. just check if it respect the rules of a trasaction. so you don't need to wait 10min to be confirmed.

If you just want to 'validate' the transaction and not 'confirm' it on block chain, do you reallyt need to broadcast it to Bitcoin block chain?
Can't you run a copy of block chain on your local system and try to create a test transaction? I am not an expert on this, I'm just making a wild guess.

He want to confirm the transactions just like miners do but in a different way, I assume. Even though he said he don't want to confirm transactions, it looks like he want confirm transactions.

[BilalHIMITE]

i think i find  a way to do it in testnet network (just like bitcoin but for research ans testing)

He want to confirm the transactions just like miners do but in a different way, I assume. Even though he said he don't want to confirm transactions, it looks like he want confirm transactions.

not confirming the transaction cause i should be a miner to do, just checking if it's a valid transaction.you insert the transaction hash(tx hash) and the appli. should say yes it's valid or no it's not valid.

Uh, my friend! You could say this earlier. Why even come with a title and discussion about "fake transaction"? See https://en.bitcoin.it/wiki/Protocol_rules#.22tx.22_messages

Is ther anyway to send a fake bitcoin or altcoin transaction?

 

LOL is that just curiosity? You can't send a fake one just like that since every single node connected is responsible for verifying each transaction as far as I know.

I think it was a mistake. He asked a different question than what he wanted.

So you trying to Learn "How to send a fake bitcoin transaction?" wow~!

[doggieTattoo]

While you say it is for research, it still looks like you are researching some kind of scam.  I suggest that you might want to post in a different sub forum with specific details of your project so that it won't look like a scam.  Because right now it does.

Please also advise others to stop providing help on issues like these, the last thing the community needs is helping scams.

[subSTRATA]

So, you trying to scam someone....

I would assume that is the case, but its not really possible to fake one in the first place; the closest thing would be a double spend.

you can't do that, very different Bitcoin and altcoin, you must learn more about bitcoin before you continue ask, google can help you

you can't do that

And this is a good thing!
