New Level: Selfdestruct and proxies

[gonzalpetraglia]

Hi,

I was thinking about a new level for the game. In this level the player should rediscover the multisig parity issue. I think this is important to be known because of the explosion of new developers coming to Solidity/Ethereum and because of the rapid growth on the usage of proxy related patterns(for example ZOS upgradeability system, some storage layout , and many others). Though some of the previously mentioned tools have checks to avoid this type of issue, I still think this is worth playing with and knowing it in detail.

What do you think?

Hi @gonzalpetraglia! Thanks for the suggested level, it is really appreciated.

OpenZeppelin Upgrades Plugins check for upgrade safety, including checking for selfdestruct.

Please wait until there has been discussion on this suggested level before writing any code or submitting a Pull Request. We don’t want you to waste your time!

I'm thinking about other levels similar to this one regarding enums or struct modification during an update.

For example a level, where a user could change a value in a struct before triggering an update that modifies said struct such that the user is able to drain the contract.

What do you think?
