When a node has seen a block it recognises as a checkpoint, any further blocks received below that height will be ignored.

It is a long term goal of removing the checkpoints entirely, because they are a source of confusion over the security model and power the developers have. But currently the role they serve is to prevent low difficulty header flooding attacks, and there has been no alternative solution proposed yet that I know of. Bitcoin consensus algo is probabilistic rather than deterministic so in theory there is always the possibility of reversibility. The checkpoint gets around that by setting how far back it with even consider looking for blocks to verify.

Would there be any way to make this behavior official? Something like "If the block was published to the network over a year ago, it is set in stone" which does not rely on the developers? This seem to be one of the few places where Bitcoin developers have a lot of authority, and it seems they generally work to keep that authority minimal. DanielH I don't see why some automatic algorithm couldn't be implemented that would be choosing suitable checkpoints during each code update.

I guess you can propose such a feature on the forum or the github project page. We really plan to get rid of checkpoints, or at least significantly reduce their power.

Your money is likely gone, but they may be able to direct you further and the scammer s will make mistakes as they go and be brought down eventually.

Try to find others who got scammed by the same "company" and pool your resources to pay for an investigation. IANAL but a class action lawsuit may be an option. This does not deserve a whole answers so I will put in a comment. RedGrittyBrick and Bill Huneke have given some good information, Sadly you cannot count on the police. But bare in mind that every bitcoin transaction is traceable. Your transaction to the scam wallet, form there bitcoins will travel through some proxy wallets to cover the tracks.

But, every single transaction is recorded in block chain. So your bitcoins can be traced to endpoint, which is some bitcoin exchange market where they were exchanged for real money. With any luck the exchange has records who received the money. Did you send them dollars or did you send them bitcoins? Add a comment. Sorted by: Reset to default.

Some information about Bitcoin and online scams Technically, it is not hopeless though. You recovering some money would hinge on this chain of events: It is not completely impossible that the perpetrators will be identified. Especially if it can be established that there are a large number of victims, thus warranting proper investigation resources.

If they are ultimately identified, it is possible they will be charged quite likely in some jurisdictions, highly unlikely in others, I imagine. If they are charged and convicted it is possible but not likely that some of your money will be returned to you. Again, that probably depends on the jurisdiction but it also largely depends on how much money can be squeezed out of them compared to the number of victims.

How to identify the perps? It is false that bitcoin transactions are "untraceable". There was a recent global bust related to child exploitation, for example, that was built on bitcoin addresses Even if not traceable today, I imagine that in the next decade or two, public resources may make it easy to track down a large number of the more significant-sized bitcoin addresses.

What doesnt work today, may still warrant follow up in a few years. Particularly in the case of large accounts Information other than bitcoin addresses can also help. They must have had a website, email addresses, maybe they phoned you. Any of those details may, in some cases, help find the perpetrators.

It is certainly possible to 'cover your tracks', but not everybody does this and does it correctly. What you can do Collect all the raw information all emails, dates and times, phone numbers or call logs, the bitcoin ATM into which you put your cash or other currency exchange details. Professional money recovery? Conclusion All this is probably a lot of work and might even entail more money invested and probably low chance of success.

Raghav Sood Raghav Sood I am not even sure BC was even involved. It could as well be that the scammers took the money, put it anywhere safe and pretended they invested it in something like BC.
