If this is sound, the theory that bitcoin is just the first cryptocurrency of its generation is now confirmed: bitcoin is dead.

If that website about bitcoin obituaries is around this update should be added there.

Clarifications as requested:

1) The article is about ECC

2) The article doesn't mention secp256k1, but it mentions EC curves in general and special those in the 256 bit field -- which secp256k1 is one of them

3) If NSA is able to crack 256 bits curves, what makes secp256k1 special to all this? Nothing.

What? There's absolutely no connection between bitcoin and anything in that article, especially not with ECC.

[wmf → viraptor]

Bitcoin uses P-256 that the NSA just deprecated.

[stevendhansen → wmf]

Nope, by a stroke of luck Bitcoin uses secp256k1 instead, which is not included in Suite B.

[viraptor → wmf]

It uses Secp256k1 which does not come from NIST.

Please elaborate.
