blockchain-challenge's Issues

Leader Post

The leader should be allowed to leave a string. A new leader can rewrite the string.

Starting Line

Add a date that the game begins. Allows people to write cracking scripts and whatnot.

"Remaining Collision"

Difficulty / progress is hard to understand.

Also, hard to communicate that it's getting "harder".

For instance, these seeds:

5
asdf168854
0.9044445127464883

Do not communicate an increasing difficulty very well.

4165759394
2632159807
1632132584
2219911122

Bounty System

How is the contract value used?

Leader Hash is confusing

Change it to "Hash Target" so competitors know that they are colliding with that specific hash.
