Demo proof-of-history and reordering attack

Greg Fitzgerald d97112d7f0 Explain proof-of-history in the readme 
Also:
* Hash userdata so that verification works as the readme describes.
* Drop itertools package. Found a way to use std::iter instead.

Greg Fitzgerald ba90e43f72 Update benchmark 
* Add asm, though it doesn't make it faster. TODO: use avx instructions.
* Do 10x less hashes, since sha256 is more expensive.

Merge pull request #13 from garious/sha256-hash 
Use sha256 hashes instead of Rust's builtin hasher.
 2018-02-19 16:43:26 -07:00
Greg Fitzgerald 0297edaf1f Use sha256 hashes instead of Rust's builtin hasher. 
Causes a 20x performance degradation. Enabling asm did not
speed things up.

Greg Fitzgerald d88d1b2a09 Reset historian's hasher between events 
Hasher will generate different hashes for the same input if it
had already generated a hash.

Also add a binary to ensure the example in the README works.
