System Parameters
Q blockchain is running and using multiple system contracts and system parameters. The latter define governance quorums, voting time periods, financial thresholds, reward allocation ratios and many other values that are crucial for a flexibly and soundly operating ecosystem Q.
System parameters are part of the Q constitution and can be changed by voting majorities through the Q governance and voting processes. Some of the parameters are governed, which means that experts take over the governance of these parameters, allowing to reduce the voting load of all Q token holders and outsourcing the parameter management to a defined (and voted) panel of experts.
