my idea is to create a software that verify automatically 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.

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

I prefer Zakir over Muhammed when mentioning me!
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.

i didn't start my project yet cause i didn't find a way to send fake transaction.

And, depending on exactly what you mean by "fake transaction", you won't "find a way to send fake transaction".

but the final code will be  on the Bitcointalk and Open-Source On github.

Good luck with that.  I suggest you start by reading the following document and making sure that you understand it very well:

like i already said i don't want to send fake transaction and wait it.
it's for research. i didn't start my project yet cause i didn't find a way to send fake transaction.

It would be fake and the bitcoin ledger wouldn't allow it.  It's impossible to cheat transactions with bitcoin.

You should probably explain what you mean when you say "fake transaction". You probably need to take some time and learn how bitcoin actually works as well. You seem to have made some very incorrect assumptions.

If you are talking about sending bitcoins that don't exist, then it isn't possible.

It doesn't matter if you "hack the math", or if you "have more than 50% of the nodes", or if you have more than 50% of the hashing power, or if you "verify the transaction". It isn't possible to get nodes to accept a transaction that sends bitcoins that don't exist.


what i mean with fake transaction, is to send a transaction that doesn't respect one of the 20 rules of a transaction : https://en.bitcoin.it/wiki/Protocol_rules#.22tx.22_messages
no matter if i send a unexist bitcoins (by the way i can send coins that do not exist but it will be rejected.) or the size of the transaction is over the maximum ....

You can send one, but most nodes that receive it will reject it rather than relaying it, so it won't get very far.

If you like you can attempt to send a fake payment to my bitcoin address. It is in my profile Tongue
if i can i will do it for you but miners or nodes will not confirm the transaction however if i can make the 20 transaction rules possible.this mean the transaction will be confirmed. i will send 10 btc. in a fake transaction.
you can easly hack the bitcoin system using 2 methodes:
1- hacking the math (the sha-256 or however), if you can crack a sha-... hash. i don't know. maybe.
2- if you have more 50% or nodes in the network or 50% of the Phashes/s you can send fake transaction and confirm it with your  nodes (fake nodes).
my idea is to verify the transaction without waiting to miners to verify it. so even if fake nodes has confirm it.

Wow, sounds like scammer behavior trying to get something for free. The only way you could do this would be to double spend but that is difficult to do and you should try it either.

Hehe, nice try.

Ad maiora!
Can be done but to be honest research is why want to do and for this reason alone is kinda stupid to or wanting to do something in the future and be scamish people use to do and still do double spending on some sites that are not protected with this and lands all sorts problems for people doing it well more so the site been in negative figures. If want to know how to do it and repeat methods Google is your friend many wont explain in full detail of how to do due to the nature of it and what steps needed to repeat the process.

i've searched on google but nothing.

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.

it's a secret research, i cannot post it right now but if i find the right helper i will announce my research. and maybe it will be Open-source.

Newbie with 12 posts... sounds legit... s/

EDIT- I got your PM and I see what you are actually trying to suggest. It belongs in the Development & Technical section.

I realize you cant post new threads yet due to your n00by status, but go over there and read, there are other people working on very similar ideas. what you suggest is not a new idea, many others are working on the same thing. There has even been talk of creating BTC address "Blacklists" in the past... you could do a search on that, but it wasn't a very popular idea...

there is a "testnet" which uses "testbits" which function the same as btc but have no value, are only used for test purposes such as you are thinking of.

also.. you might want to think of a less provocative thread title  Wink

good luck.

No I dont escrow anymore.
Is ther anyway to send a fake bitcoin or altcoin transaction?

 Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh Huh
Yes.  I can help you with that.
Send me a PM.

Don't bother to do that. It's gonna be rejected by miners,
Also buyer will wait for at least 1 conf before releasing product... (which will not have even 1 conf).

it's just for research.

It might get your node banned, be careful its not only rejected to miners, but also by all nodes.
