First, the delegator needs to choose a reliable blockchain platform, such as Ethereum, Bitcoin, etc. These platforms provide smart contract functionality, which can be used to set up the reward address.\\n\\n2. The delegator needs to write a smart contract for managing the reward address. The code in the smart contract can implement the functionality for distributing and extracting rewards. To ensure security, it is recommended to use the official programming language  and compiler provided by the platform, such as Solidity (Ethereum) or JavaScript (such as Truffle)."}]}],"pr":"166c5e4aa156bed9073576c715b3bb3d1095049f1b1eb22270747c33483b8aac"}
