Every user should call user state transition to process received reputation

  • See (the definition of user state transition).


npx ts-node cli/index.ts userStateTransition 
                  [-e ETH_PROVIDER] 
                  -id IDENTITY 
                  [-b START_BLOCK] 
                  -x CONTRACT 
                  (-dp | -d ETH_PRIVKEY)
  • Every user should execute user state transition by hisself before executing any action in the incoming epoch.

  • It will generate a user state transition proof and it can be verified at the Unirep smart contract.
