On-Chain and Off-Chain Processes On-chain Operations Contract Processes:

  • ◊ Start call ◊ Locks caller withdrawals ◊ Locks caller calls
  • ◊ End call ◊ Verifies signed confirmation ◊ Settles payment ◊ Unlocks caller
  • ◊ Deposit ◊ Stores funds on the OC in order to be used for further calls or to be withdrawn later
  • ◊ Withdraw: ◊ Delayed by 10 blocks ◊ Allows for withdrawing funds from contract by address holder
  • ◊ Lock check: ◊ After initializing a call, which is confirmed on-chain through the OC, the recipient needs to check if the called is locked on the current call to prevent abuse and misuse.

Off-chain Processes:

◊ Call_conditions: ◊ Rate ◊ Call identification ◊ Start timestamp ◊ Addresses

◊ Confirmation: ◊ Rate ◊ Call identification ◊ Start timestamp◊ Confirmation timestamp ◊ Addresses

◊ Signing ◊ The caller signs both call_conditions and conformations with his or her private key. The OC and recipient verify if the data is valid. Once the signed confirmation is received, the recipient starts the call and the caller’s funds are locked.
