how can i create fake transactions

[ranochigo]

i dont care if it gets saved in the blockchain i just want it to count like if i send it to an adress it will show up but because its fake it will just disappier because its invalid

This is not possible.

This is possible. Just define what do you mean by "it will show up"
If it means "it is visible on some block-explorer site" it is definitely possible.

Take this one for example:
https://blockchain.info/tx/ba8a7fb13a507a4987bfa267a6f12defc0d30216fdf6664cdc06cc4c8de71a84
This is fake transaction.

yeah this is what i wanted to know
how do you do it?

That address has a private key generated with a secret exponent of 0. As with that, the coins cannot confirm since the network does not see any transactions being generated by that address as valid.

That being said, the transaction SHOULD NOT have appeared anywhere in the first place. Any node without bugs would have rejected it and it wouldn't have appeared. The only reason why it has appeared is because Blockchain.info is quite full of bugs and they accept invalid transactions without checking first.

2 questions first did you lose the bitcoins you tried to send
second how do i replicate this

1. There were no bitcoins which could be lost because this TX is not valid.
2. You should learn to read. The post above your clearly mentioned it: That address has a private key generated with a secret exponent of 0.

I actually don't see why you wan't to create such a transaction. You won't be able to trick someone with that. This TX will get rejected everywhere.
But if you still want to create such a TX, then please read into it. Its not that hard.

I think that the question was: "is creating fake transaction free or one should spend real funds"
This depends...

The post above your clearly mentioned it:

This is clearly not truth

2. You should learn to read.

This is good answer.

you can try , creating tx with 0 fees and try pushing it to relay nodes. so any nodes accepting 0 fees tx will accept it.,

but this wont qualify as fake tx, its just real tx with no fees, so it will take time to confirm.

how can i do it tough?

There are at least two possibilities:
a) Learn math, programming, bitcoin, blockchain, etc. In ten years you will be able to do it.
b) Pay to somebody and ask to do this job for you.

[TechPriest]

so i want to create a fake transaction 1 that will go trough but will not get confiremd because its not real how can i do that?

It's very simple: create transaction without comission. With 0 sat/byte. It has a chance to be not confirmed (before it will be deleted from mempool).
there also some more comlicated ways. Ask "Amaclin" he can create transaction with 100 bitcoins which will never be confirmed.

i dont know how i do it do i use a program or what?

[ezhui]

Very interesting idea. I think thousands people have thought about it and tested for millions of times.

But you won't get through the first full node before spreading out to others. Each node of bitcoin network will verify the delivered transaction using the full blockchain. If the transaction breaks the rule, the node(could be miner) will not include it into its block, otherwise it will be refused by any peer miners and the sender miner will get paid with nothing.

go to any online tx creator .e.g  https://brainwalletx.github.io/#tx

set fee 0.00 i.e. output = input

enter input address and output address.,

both can be same, it does not matter. ,and push your tx hex to relay nodes.,  amacilin has shared , tool to push tx to nodes using just ips list., you need to use that. try looking in old threads.

good luck

What is the reason you want to this,because I don't help scammers..

[robertdemarco]

Hi
I am going to open a online store and I have to test the bitcoin api, therefore I do need this feature sending unconfirmed transaction (create fake transactions)
Brainwallet is not working for me.

There is a program named BTCtxGen which is for sale, but seems to be a fake.

Is there somebody who can help me please.

[investerS]

But why on earth should you create a fake transaction?

[nmmnasr]

No idea on fake transactions.

I got some coins from somebody but that is still unconfirmed in blockchain.info.
How can i find out that it is not fake?
Any place for checking validation of transactions without bug?

What do you mean?
You mean a transaction without fee is fake and the sender spent nothing until a miner confirmed it?

Fairly confident that in your case you want to test/debug your system using the testnet not the mainnet. Sounds like you want "real" transactions, but in a no risk environment

That discussion on SE is not "details". It is "nonsense".
