FIO Producer Ranking

This is the current ranking for block producers on the FIO network.

These rankings are generated by measuring performance, and participation in maintaining the network as measured by the fio-bp-vote utility. Maintenance includes updating fees to keep pricing at a reasonable level, participating in contract updates, and a series of maintenance calls that optimize state or trigger reward payouts

Three criteria negatively affect ranking.
 ▸ Slow CPU, currently this is defined by an average time to execute a transaction longer than 5,000µs. Producer CPU time is viewable on the FIO stats site.
 ▸ Never having claimed rewards results in a score of -100, since this indicates that the producer is not likely active.
 ▸ Finally having no votes is an indicator that a producer is not active, and results in a score of -200, but if a registered producer has neither claimed or received votes they are not considered at all
