Bitcoin Forum

Hello, every one, i wnt know if know how cancel a deposit in blockchain.

is that possible?

Greetings

Once it is processed, there is no way to cancel it. All the bitcoin transactions are irreversible..

I think that you would have to pass along more details of the transaction in question for anyone (even the experts here at bitcointalk, I am not an expert).  My *guess* is no.

Quizas Ud. puede preguntar con detalles y palabras EXACTAS en la parte del foro en español.  Pero, supongo que NO.

Good luck.
Suerte.

I think it is possible if the transaction is unconfirmed by double spending..It is almost impossible if it is confirmed.

Yah that can help in case if someone wants to kick a bitcoin transaction from mempool.But if it gets even 1confirmation it cannot be cancelled.Also now most of bitcoin wallets don't allow double spend which makes it hard .Though you can still pass on a double spend transaction doing a little bit coding on core wallet.

Nope you cannot cancel a transaction in blockchain. So always think twice before sending money when it comes to BTC.

What site did you buy from? What happened? Share your experience. Perhaps it could serve as a warning to others.

ok, thats fine, the question was because i think that in some cases when you make transactions with others in here and they give you some address for deposit, maybe you culd say..  lets sent it at the same time and lets check together the blockchain record (i dont know the blokchain for other currencies) but if the other dont sent the coins then find the way for cance the deposit.

is this a really crasy idea????


greetings

There are 2 possibilities, either you want to send bitcoin or any altcoin to any address or you don't.
If you do then nothing can reverse the transaction, how ever if still not confirmed you may double spend it which I think you lose everything
Only the coins never reach the destination, I'm not sure how double spending works and if detected by block chain what happens to the coins
But when confirmation happens nothing can bring you back your money, sorry if you lost cash to scammers.

not yet, but is something that i want avoid.....


thanks

But really you cannot cancel the transaction you send because blockchain dont have the features like that. And thats what taking advantage for the fraudster because they knew bitcoin dont have cancel button and anonymous they make ways to scam people like making hyips,investment program and any other scam attemp existing there, not having cancel button for blockchain really not big problem and it helps people to be anonymous online but if you get victimize by scam or fraud well you will curse it because you lose your money.

I read somewhere that you can:
"To send to the network transaction uses the same inputs coins to your address + add to it another 1 Bitcoin such as ++ and add more commission - its first grab any pool once - and the first transaction will be recognized as erroneous" (c)

The phrase "to cancel the transaction" is not applicable for Bitcoins and networks. On cancellation of the transaction can only speak as part of the service, ie, transaction handler.
The transaction is sent to the network scatters on clients and reach the miners. Enabling transaction block miners, will confirm.
attack scheme should be like this: we send a transaction that comes to transaction processor in payment acceptance service (a "subnet") and almost simultaneously send another transaction that uses the same input as the first miners in the nodes (the other "subnet").
As a result, the unit will be turned on the second transaction and the first ever confirmed as the inputs used in the second, but the service has reached the first.

I think no, there's no chance to cancel a deposit. That's why i always check more before i transfer to someone. Well, i hope someday blockchain have this fiture.

It sounds like you are trying to find a way to send a btc transaction in exchange for something but cannot be assured of delivery. In this case you will want to use a trusted third party for escrow. Some alt coins are developing escrow built - in to the wallet, such as syscoin

It is impossible to cancel a transaction, if you are referring to the bitcoin network.

The bitcoin network is by nature decentralized and therefore irreversible. It is impossible to reverse a transaction, so you should always be careful sending funds to dodgy people. You'll get scammed.

unfortunately you can't take back your coins once you have sent it and get into transaction,its just like if you sent money from ATM,you can cancel it,because if this feature exist in bitcoin transaction,every people have a chance to be scammer.

Agree with you..

Estoy de visita en el Peru por el momento.  Rodeado por mis cunados.  "Si no practico espanol en la casa, me pega la jefa!"

(Chiste!)

Visiting Peru (on business and pleasure), enjoying my very decent in-laws.

Parace que hay MUY poco de BTC aqui...

Hardly any Bitcoin activity here, but Peru is not in chaos like Brazil, Argentina and Venezuela.

one thing that you could do however is to make sure you are sure with what you are about to do.  ;D
transactions are irreversible, that is also the reason scammers cram here in the forum to take how much you have. escrows don't even guarantee.

Bitcoin transactions is irreversible, after you click the send buttons you can not cancel the transaction. Therefore if you want to transact using bitcoin, you have to carefully for each transaction. thank you

Acá en México desde hace años en algunas revistas como PC MAgazine en sacaron algunos artículos, incluso en los CDS venian algunos programas básicos de minado desde CPU (Estamos hablando de 10 años tal ves)  yo incluso traté de hacerme de algunos bitcoins en ese tiempo. Pero sin mucho esfuerzo. Recientemente (creo que hace como tres añños) salió volabit que compra y vende Bitcoins en México desde bancos y tiendas como 7 eleven u oxxo y paga por medio de transferencia bancaria.

bancos como BBVA Bancomer y Santander han invertido al parecer ya en Bitcoin pero son Españolas, asi que no es un merito propio de nuestro gobierno.

Debido a la paridad peso dolar el valor del Bitcoin es casi del doble de lo que era el año pasado, asi que me arrepiento por no haber tenido la visión de ponerle más esfuerzo a la adquisición del bitcoin  ; P

pero bueno, ¿poco a poco amigo, y en que parte del mundo resides?

Saludos.

Here in mexico since several years in magazines like Pc Magazine in spanish, some articles was starting to talk about Bitcoin, even some CD's include little programs for minnig with your CPU (Maybe 10 years ago) even me try to get some BTC in that time but without real effort. Recently (like trhee years i thing) volabit star to buy and sell BTC using convenient stores like oxxo or 7 eleven and pays by bank transfer.

looks like Some Banks like BBVA Bancomer and Santander are investing in BTC but there are from spain so our govermnet dont have merit.

for the difference between US Dollar and Mexican Peso the BTC cost is almost the double than the last year, so im regreet for dont keep some BTC and live without that vison ; P

Well, baby steps, where in the world you live?

Greetings

You can cancel the deposit if the proccessing is not starting yet but if  its already processed you cant cancel it anymore..
Unlike paypal that you have a power to reverse the payment..

This is one of the reasons why merchants love Bitcoin. The charge back problems on credit cards are a big problem and people exploited this to it's full extent. The Bitcoin tx's are irreversible after the 1st confirmation was received on the Blockchain. It might be, that some Bitcoin service providers or payment processors, might introduce some feature to accommodate this <off-chain> Xapo?

yea but you cant do anything against fraud.

specially in here.

is really difficult make real money when even in sites for borrowers the fraudulent people can just run with your money

without a current international law about bitcoin is difficult being protected in all this cases.

Greetings.

With great powers come great responsibility. "Being your own bank" means that you have the power to send your funds wherever and with a low cost, but the drawback is that you are responsible for your transactions. If I send funds to a scammer, well that is my fault for being ignorant, and yes I have learnt that the hard way.

Even if say the UN had a law banning scams on the blockchain, it's not like anyone could enforce that so called law.

Yeah you cannot stop fraudster when your using and dealing with them, and if you really send your money to the fraudster say sorry to your money and begin to moveon nowadays sacammers/fraudster find different ways to attact people so that they will successfull to their plan and all we need to do is be careful because blockchain dont have cancel button in every transaction we made.

Bitcoin is good and bad in this way. You have to be 100% sure of the legitimacy of the person you're sending the bitcoin to, because once sent, you won't see that bitcoin again unless the recipient is a super nice guy and refunds you.

The thing I think is very unlikely for this time, because the system is still not as good as Bitcoin Paypal. and this can cause a panic at the receiver that performs transactions, my advice if you're doing something better seen in the past that people can be trusted or not

You can't actually do that, because right after you send the Bitcoin to the network. There will be a confirmation, and after it confirmed you can't do anything about it.
But in other case, there's a transaction that failed to send because of a 'double spending'.

Remember the red once. when you check your balance on blockchain.info it is on Red button meaning that your transaction is waiting to be process so it name unconfirmed and when it has 1 confirmation of more you cant do anything at all. Try to double check all your investment sites before you deposit bitcoin. Sometimes you knew that is fraud when its to late. You deposit such amount and it will gonna be scam.   ???

yea, we have to be always in alert  ; P

You cant cancel if the transaction is now on process. You cannot tell it to stop. The only way to retrieve your deposit/withdraw is to contact the address you are depositing/withdrawing.. But if you are lucky enough there is a chance that the processing time will be cancelled. I dont know why. But others reported that blockchain sometimes cancel transactions.

I think as long as your transaction has 0 confirmations, you can cancel it. But, if your transaction has already 1 or more confirmation, then you cannot do anything about it anymore. That's why we should think first before sending transactions and make sure that the person you are sending to is a legit one so you will not encounter these things.

If you used services like Xapo, and the transaction was still off-chain, you might just be able to reverse the transaction before it goes on-chain. < On to the Blockchain > The basic person to person transactions on the Blockchain between Bitcoin addresses directly are not reversible. ^smile^

Who would be making these decisions, on what transactions get reversed? The Blockchain is a chain of transactions, so how do you take out a single tx, without dropping the whole chain of transactions after that?
