Any account that has harvested a block in the last 3.5 days is considered to be an active harvester.
Total harvesting power is estimated by identifying all of these accounts and summing their importances.
A fork is successful if it attracts a majority of network harvesting power.
Any nodes that are unresponsive at the time of report generation are placed in the yellow 'delegating / updating' bucket.
For delegates, an enhancement would be to identify the status of the node(s) to which they're delegating.
