Bcrypt in an alternate cryptocurrency...

[The Fool]

http://en.wikipedia.org/wiki/Bcrypt

Can it be done? I ask this because Bcrypt's cipher Blowfish is a notable cipher since there is no effective cryptanalysis on its full-round version. It has been tested since 1993. This may be the strongest, most well-tested hashing function that can be incorporated into a altcoin.

Scrypt on the other hand is VERY experimental. SHA-256 was created by the NSA in 2008. Enough said there.

So, if anyone wants to create a altcoin that uses Bcrypt as its hashing function and within its digital signatures, I will mine it and invest in it -- as long as you don't go crazy with other features. Stay true to the original bitcoin formula.

Thoughts?

Bcrypt is obsolete in comparison with scrypt. The scrypt function provides more than 4000 times higher operational costs, in comparison with bcrypt.

But combination of scrypt+(another function)+bcrypt may be interesting.

That's not even a fair comparison. Obsolete is not even the correct word since it is still held in high regard and fully-functioning.  It is not all about the operational costs but the security of algorithm. Scrypt hasn't even undergone cryptanalysis as far as I know.  Unless it is based on Blowfish? If not, I would still rather put my money in something with 20 years of exposure and testing.

Algorithms are serious business and it's not something that is usually gotten right in the first shot. Scrypt could end up flawed and broken one day and not because of bruteforce.

Additionally, Bcrypt can have its workload upgraded from what I hear. Probably as high as Scrypt. Again, it's not just about workload. It's about sound cryptography.
