just a suggestion. Don't sell your skeincoins to cheap.  Grin

I'm just gonna share a snippet of a paper i just got my hands on and let you all get like giddy school girls Smiley



If you're wondering what a "generic adder" is, it is just an unoptimized adder in VHDL, without the built-in adders of certain FPGAs.

Nice conclusion: Skein-512 ASICs exist... and are 32nm tech... very interesting....

The paper is very Discrete Math heavy, so if anyone with a good grasp of it wants to check it out, i can send it to you. PM me. (this can be found freely on the interwebz, i'm just sending it as a convenience)

This is the link for the [39] reference http://csrc.nist.gov/groups/ST/hash/sha-3/Round2/Aug2010/documents/presentations/WALKER_skein-intel-hwd-slides.pdf

Intel implemented a Skein-512-8R ASIC...... WOW!

Unfortunately those asics cannot be used to mine coins.

How is that?

Rehashing (pun intended) my generic answer to these questions...

There were SHA-2 ASICs way, way before the first Bitcoin mining ASICs. They were not suitable for mining due to I/O limitations: you'd have to push a relatively big load of data for each single hash, and the chips were not fast enough for that. What mining ASICs do is generate most of the data on the fly (by incrementing the nonce) so there is no I/O bottleneck, in addition to the actual hashing. However, the nonce business is easy, so if you can implement the hash, making a miner is only a matter of time and financial sense.

Indeed, i was just stating the fact that, not only there's an FPGA implementation (publicly available) but that someone already did an 8 round Skein implementation on an ASIC, and it was fricken Intel!!!!

Currently there's no financial sense on building ASICs for Skeincoin, but as a proof of concept, this sets a very good precedent (Skein embraces ASICs contrary to other alts).

Afaik bitcoin asics return nonce, while the asics posted above return hash. Theoretically they could be used for mining, but it would take a lot of i/o operations.

Skeinsocks have landed!

After finding a new supplier this is the new result:). We are very happy with the current supplier and expect to have a long and lasting relationship.

Get your set of 5 socks now for only 3500 skc.

The first shipment is already on its way to Venezuela, Chiquereitor.

Seems coinmine is affected by the recent openssl bug.

In the GitHub repository, it looks like Skeincoin uses OpenSSL 1.0.1c (for example here, line 17). This version is vulnerable to the Heartbleed exploit, so it should probably be updated to 1.0.1g, which is what bitcoin-qt currently uses.
Do the binary builds use the vulnerable OpenSSL version or have they been updated?

Btw, go to the Bter.com thread

https://bitcointalk.org/index.php?topic=502363

And ask for  Skeincoin to be added to the poll Wink
