----------------------
1. Blocks (To be done)

A block can vary in size and is processed at last after 15 minute or when it reached it's max size of 1024KB.

1.1 Guarantee of deliver (to be done)

When a block is not processed after 15 minutes, it is paddedd with null bytes, which is a forbidden char in block dat. <-- xxx crap ntbd)
### TODO: –((Talk with boss about this bullocks idea))

-----------------------
2. The brithash

Brithash uses the skein512 hash algorithm in hex representation as it's only hash algorithm.

2.1. Prove of work

All Blocks content is hashed to generate the initial nounce-zero.
The prove of work is a hash of this nounce-zero with a 32 hex chars long nounce which results in a hash value below the difficulty.

2.1.1 Difficulty settings

The difficulty setting is a value between 0 and hash max value.
The prove of work has to be smaller than max-value - difficulty
The initial difficulty is 2^16, which requires 0x0000......................... (4 leading zeroes)


3. Mesh Networking (tbd)

4.1 Examples
In this section you find various examples.
### TODO: improve legality and copyright

4.1.1 Skein Assembly Implementation for SOCs and gfxcards and webjs and all (tbd by livinskull)
TBD

4.1.2 Example hashes

Your job is to find a nounce that produces a hash that fulfils the difficulty settings
