 security. We expect the validators to execute the protocol correctly. They get rewarded for doing so and punished otherwise. Each validator has some self-stake and some stake that is delegated to it by other token holders. The validator and delegators share the reward and risk of slashing impact with each other. 
 
-The total stake behind consensus should be taken into account when value is transferred via a transaction. The total value transferred cannot exceed 2/3 of the total stake. For example, if we have 1 billion tokens, we aim that 300 Million of these tokens is backing validators. This means that users should not transfer more than 200 million of this token within a block.
