Skein

1. More than likely the most secure hash function on planet earth.

2. Skein-1024 is integrated with 'Threefish' (with a threefish bit strength that matches that of the Skein implementation) ; 1024 = 1024 (ratio perfect)

2a. Addressing the concerns regarding Threefish and the alleged attacks that were found on several of its rounds (response from one of the co-authors of Threefish [as well as Skein] = https://crypto.stackexchange.com/questions/11725/has-threefish-successfully-been-attacked-practically-or-theoretically/11727

2b. Attack in question was mentioned in this paper (published by the team ) = http://www.skein-hash.info/sites/default/files/skein1.3.pdf

^^^ SHA-3 finalist (but Keccak was the hash function that won out ; Ethereum is using Keccak as we ll, but not the same iteration as w hat was submitted to the NIST)

3. Threefish McOE Mode = https://eprint.iacr.org/2011/644.pdf [exponentially more secure than the original Threefish - seems that there are *very few individuals out there right now that even know that this exists*] <— that's interesting, going to have to do more homework on this

Is it possible to draw from an implementation of Skein-1024 that utilizes Threefish (1024) McOE mode?

Link that attests to the fact that SKein-1024 is the equivalent of 2^452

Has threefish successfully been attacked (practically or theoretically)?

Reading Schneier's "The Doghouse: Crypteto" dated September 30, 2009, I noticed Bruce Schneier stating:
Threefish, the block cipher inside Skein, encrypts data at 7.6 clock cycles/byte with a 25...
