 The first 1,580,851 blocks after the genesis is called Singularity, during which everyone can create a validator and stake tokens but the active validator set will only have the genesis validators. There is also no new token emission, hence no reward. Unstake and redelegate are also not supported.
 
-The Genesis validator set consists of 8 validators, setup by the foundation and trusted staking institutions. 4 of them support locked tokens and the other 4 support unlocked tokens. Each of them has an initial stake of 0.001 IP. Each of them will have a default 7% commission rate. During the Singularity, the genesis valdiators will need to self delegate at least 1024 IP to perform validator operations like editing validator commission rate.

 After Singularity, the top 64 validator nodes with the highest stakes will be selected to participate in consensus and receive rewards.
