Thanks:)
I edited my post and added an other link.

@krogo,
Although i would love to get a copy of Mycelium Entropy device as a collector, i wouldn't use it for serious purpose.
Indeed, i think the source of entropy is too limited:

Yes, with a Ubuntu Live session everything is compute in RAM. Once turn off all the data are gone. That way no need to drill or burnt HDD.

Yeah, perhaps it is even easier to use a Ubuntu LIVE session...Just my 2 cents...

I understand it the same way. I tested a few based on the list and it seems they are all safe.

However, given the nature of the hard fork, if it happens, it is still possible that everybody will be forced to move, even owners of safe addresses...In fact i don't know exactly. Any idea?


Thanks. I hate what i'm going to say, but feel free to give me some merits if you think i deserve it...

So to sum up regarding casacious coins. I checked some random addresses taken from:
http://casascius.uberbills.com/
and they don't seem to fall in the P2PK category. Therefore, if unpeeled, these coins should
be safe.

Fell free to elaborate if you think i'm wrong.

I think you are confusing the address and the public key. It is possible to compute the address from the public key via hash functions, but quantum computing can't derive the public key from the address.

The threat of quantum computing, is that, these computers might be able to derive the PRIVATE key from the PUBLIC key, via shor's algorithm.


In fact, the website already list all the vulnerable addresses. It is something public.

I final note though, if after entering an address, you see something:
0 BTC compromised

I think that it does NOT mean that this address is safe. It is just that the balance is displayed as an integer...
Therefore you may have something like 0.7 BTC unsafe...

Hope it helps 

Hello,

I'm not an expert, but i came across this excellent article, which explains the real threats:
https://fr.tradingview.com/news/cointribune:91fc5a278b858:0/
For those who don't understand the French, basically the vulnerable addresses are the ones
for which the PUBLIC key has been exposed. It can happen if and only if
1) You used a P2PK address (very unlikely if the wallet is created after 2011)
OR
2) You sent BTC with that address and you don't use a change address,
that is a separate address with a new UTXO. Nowdays, softwares like
Electrum use new addresses for each transactions.

There is also a tool where you can check the vulnerability of a particular address:

As said above, i'm not an expert, so please feel free to contradict me if you think
i'm wrong. I hope it helps nevertheless.
