Lifeguard just in case you mess up sending BTC transaction

[jaitor]

It's so easy to make a mistake when sending bitcoins (wrong copy paste of wallet or whatever...)...
Even if it's only once every 100 transaction if your mistake happens when you are moving huge amount of btcs..you are done. You could lose all your savings in that moment. I think there should be a lifeguard, something to make it possible to cancel the transaction you just maid..at list for 10-15 seconds...

All the people here have certain computer skills..do you imagine your mother or grandmother if bitcoin gets more popular sending btcs without a method to turn back and doing it always perfect?

I like your idea. I don't think the protocol can accommodate this. But perhaps some kind of service that relays your spend, with a grace period before they broadcast it to the blockchain?  I'd pay a tiny fee for that piece of mind. No matter how may times I buy stuff with BTC I still cringe a little when I hit the send button.

scenario
instead of todays protocol asking for a fee upfront, it sends a free signed transaction onto the network (we all know they never get added immediately to blocks). users then have time to send a duplicate signed tx with a fee to get priority, cancel transaction or carry on for freeafter seeing a message:


"x btc sent to X address are you sure?"

[_pay priority fee_][_continue for free_][_cancel transaction_]
agree, hurry up         do nothing, ill wait           oh crap cancel

the continue for free sends nothing

the cancel TX is the signed TX (has to be signed to ensure proof of owners decision) with a message 'cancel' embedded into the tx, which miners can easily code a reader to check before adding to blocks. and would remove from their transaction pool if seen. by having it signed

all that is needed is to get the bitcoin devs to add some code to prompt user and then resend tx with a fee or "cancel" request. and get the mining software developers to add code to look for "cancel" message. after all they already have code that searches out tx's with fee's

If it helps any, the Envrin Web Wallet has a delayed sends feature (see sig).

Amazed to see this reply from a legendary and foundation member...
No offend.

don't store all BTC in 1 wallet ... like in real life.

maybe that could be implemented in a wallet program,but not in the blockchain

the blockchain is just data. it holds no programming or code. just a list of transaction blocks.

the code part is done by wallet apps to relay transactions out, and to display confirmed transactions..and other code in mining software. as i said nothing needs to be done to the blockchain data apart from continuing to store transactions that are in solved blocks.

its for the wallets and miners on the outside to change their protocol on which transactions end up in the waiting list for the next block

yep i wasn't thinking about implementing it in the blockchain, a middleware in the bitcoin client should be a better approach...
