wait I just thought of something, what if you made it so you can only use someones address in which device it was created from or certain devices you allowed. Like if I tried to make a trillion^22 addresses and got someones on my wallet.dat it still would not work even if I had there private key and public address because It was not the device that created the address. Like a picture of satoshi pops up and gives you the finger or something. I mean something needs to be done. I dunno I am a not a coder man guy dude.

and when whoever, as a legitimate owner/creator, loses the device will also lose access to coins in it
would you like that to happen to you? losing device = losing your coins Tongue

Anyone who has access to the private key can autonomously reassign any funds associated with that key. There's no way for the "rightful" owner to block any transactions which did not originate from his/her device. All that is needed is a transaction signed by the private key.

Sidechain solutions like Lightning complicate things, but in general, if someone possesses a private key, they can do whatever they like with the funds. The key itself is the authorization.

The chances of any individual, or even a collaborative effort like LBC, ever finding a properly generated key (not one which is deliberately weak), are so small as to be effectively 0.00000. In fact if someone were to do the calculations of the probability, 0.00000 (rounded up to 5 decimals) would probably be accurate. Smiley

You would be more likely to lose funds due to some event somewhat within your control, like a hard drive dying, or a trojan stealing your wallet.dat file, rather than someone on the other side of the world brute force cracking your private key.

Tell me please, I heard that on this forum or GitHub there is a large list of found Bitcoin private keys where BTC transactions have ever been. (with Balance: 0 BTC)
Please share this information.

Please share this information.

These threads share some of that information:

Collection of 18.509 found and used Brainwallets

Bitcoin puzzle transaction ~32 BTC prize to who solves it

As well as finding SHA256 brainwallets I have also discovered 5000+ miscellaneous private keys. Some of them are deliberately weak (eg private key 0x1 compressed / uncompressed) but many of them look just like a properly generated random key. I can't release them because some of those keys belong to my own wallets. (Before anyone asks, NO, they do not have funds, and NO, apart from the really weak ones they were not brute force cracked. That doesn't work!)

there is no way to prevent the bruteforce of private keys, and with the development of a quantum computer it will be millions of orders of magnitude faster.Satoshi himself was laid in its algorithm that opportunity . Grin Grin Grin Grin

Yep, but even quantum computers cannot get private keys if the public key is not available. ie. if the address has no transactions out.

So if you are using bitcoin correctly you wont have a problem even with QC:s in use.

you can't really prevent brute forcing, but perhaps make it harder... Undecided
I think using a multisig address will add some degree of difficulty to brute forcing attempts

Explain - if the speed 134.23 MKey/s - how much variants the private keys is generated for one hour?

Thanks!
But I can multiply numbers.
Me the dimension of size MKey / s interests.
For example, 1 MKey / s - is how much the private keys are: 1, 10, 100, 1000, 10000, 100000, 1000000 or other meaning ?

Author can correct me if necessary, but I presume 1 MKey/s would mean mega-keys, ie it's trying 1 000 000 (one million) key combinations per second?

It's brute forcing so every raw private key attempt has to be mapped (through public key generation plus hashing) to an address.

What's wrong with you, folks? Read the first page of the topic again! The author had CLEARLY mentioned:
On my hardware (GeForce GT 640) it gets 9.4 million keys per second compressed, 7.3 million uncompressed.

I know many different units of measurements: meters, kilometers, minute, seconds, ft, km / hour, the mile / hour etc., with this unit (MKey/s) has met for the first time.
I assumed, that 1 MKey/s it can be 1 000 000 Key/s, but has decided to ask the connoisseurs.
