-- System contract: A contract that affects protocol. The currently deployed system contracts are as follows: **AddressBook**, **Voting**([KIP-81](https://github.com/klaytn/kips/blob/main/KIPs/kip-81.md)), **StakingTracker**, **TreasuryRebalance**([KIP-103](https://github.com/klaytn/kips/blob/main/KIPs/kip-103.md))

 #### Execution
 
-The Registry deployment is executed at the `Finalize` function, which means the end of the block generation. It reads the reserved address and runtime bytecode and deploys the Registry by the bytecode injection. Also, it injects the state for pre-deployed system contracts here. Note that the Registry contract will be deployed at th parent block of the `kip149CompatibleBlock` since it needs to be ready at the `kip149CompatibleBlock`.
