[Proposal] Adding an isOwner Function to the Validator Smart Contract


The isOwner function provides a way to verify if a specific address corresponds to the owner of the validator smart contract. This functionality can be useful in various scenarios, such as:

  • Restricting access to certain administrative functions within the contract.
  • Granting voting rights or other privileges only to the owner.

Implementation Details:

  1. isOwner Function:
    • Define a public function named isOwner that takes an address argument (owner).
    • Inside the function, compare the provided address (owner) with the stored owner address (owner).
    • Return true if they match, indicating the address is the owner. Otherwise, return false.

Solidity Code Example:

    // isOwner : check if the given address is an owner or not.
    function isOwner(address owner) public view returns (bool) {
        for (uint i = 0; i < owners.length; i++) {
            if (owners[i] == owner) {
                return true;
        return false;

  • Improved security by restricting access to sensitive functionalities.
  • Increased flexibility in managing validator permissions.
  • Enhanced transparency by allowing users to verify ownership.

This is from @0xbeny idea, I just help him to improve the code

This implementation could add many benefits to potential developments in the future where owners/operators can be verified for specific purposes within an application or for voting rights. I like the proposal.

This looks like it will be quite useful!

This is a very cool idea. What if we also had a wallet swap function. If the wallet ever gets compromised the owner can swap to a new XDC wallet without shutting down the node.

Looks good

Looks good. It makes it easier to verify the owner's address in one function call.
