In the Moment we have 10.6% but not a shard limit. So 1 Validator can grab 106 Keys for one shard and halt it or even the whole network. Those % are on total Keys but if the balance in shards are not optimal those % will increase so let calculate with 190 Keys in worst Key instead of 250 Keys
7.2% - 18 Keys per Shard – 9.47% - 3.5 Validator to halt
6.4% - 16 Keys per Shard – 8.42% - 3.9 Validator to halt
5.6% - 14 Keys per Shard – 7.37% - 4.5 Validator to halt
4.8% - 12 Keys per Shard – 6.31% - 5.27 Validator to halt
3.2% - 8 Keys per Shard – 4.2% - 7.91 Validator to halt
What I don’t understand how Robo calculate Keys based on hardware and cost. Does this mean you run all keys on one machine? If so we have there a higher risk if one machine goes down.
