Genesis Genesis

N.B: This crate's Cargo.toml file has been disabled by renaming it to _Cargo.toml. It no longer builds due to changes in the project structure.

This crate isn't strictly part of grin but allows the generation and release of a new Grin Genesis in an automated fashion. The process is the following:

Prepare a multisig output and kernel to use as coinbase. In the case of Grin mainnet, this is done and owned by the council treasurers. This can be down a few days prior.
Grab the latest bitcoin block hash from publicly available APIs.
Build a genesis block with the prepared coinbase and the bitcoin block hash as prev_root. The timestamp of the block is set to 30 min ahead to leave enough time to run a build and start a node.
Mine the block so we have at least a valid Cuckatoo Cycle. We don't require a given difficulty for that solution.
Finalize the block with the proof-of-work, setting a high-enough difficulty (to be agreed upon separately).
Commit the block information to github.
Tag version 1.0.0 (scary).

N.B. This was written while listening to Genesis. Unfortunately, I'm not rich enough to do it while driving a Genesis. And that'd be dangerous.

Usage
