Hi @Cornycoin69

In light of the financial aspect of the project and the distribution of prizes, could you explain on the security measures embedded within the smart contract to guard against potential vulnerabilities?

After asking a few tron devs I was told it’s pretty much impossible to make it so nobody could cheat if we made the big prize’s connected to the nft or smart contract, because someone could front run the node and predict the prize coming. This is why we chose to use a random number generator and whoever owns that nft with that matching number will get the prize sent to their wallet. So at different milestones starting at 250mints we will do drawings and begins distributing the prizes.

If only the owner of contract can execute the call to the winning number generation function using the same random number system as a random mint, based on parts of the blockchain to generate it, how can others cheat here?

By running their own node and front running the next few mints in the contract to wait to mint a prize winning nft

This was the warning as it was explained to me during development

using this to generate a random number:

uint(keccak256(abi.encodePacked(block.timestamp, block.prevrandao)))

and if you are the owner of the contract, and you set onlyOwner to call the funtion, i think it is very very complicated one node can do it when noone knows when you will call this funtion exactly
