TL;DR

  • Rewrites Nodes contract using the ERC721 standard as a base
  • Adds a bunch of tests for the new smart contract
  • Removes a deprecated flag from our mockery config

Why ERC721

  1. It doesn't seem crazy to model this registry as a NFT, so we might as well use the standard.
  2. We get all the OpenZeppelin audited smart contract libraries for free
  3. It'll work with the entire rest of the crypto ecosystem (external indexers, other smart contracts, etc) automatically

AI Assisted Changelog

  1. Smart Contract Changes:

    • Implemented ERC721 standard in the Nodes contract.
    • Added new functions for node management using NFTs: addNode, removeNode, updateHttpAddress, updateMtlsCert, and updateHealth.
    • Added events NodeUpdated and NodeRemoved for better tracking of node changes.
    • Restricted node ownership transfer.

  2. Go Bindings Update:

    • Updated the ABI bindings to reflect new changes in the Nodes contract.
    • Added data structures NodesNode and NodesNodeWithId to handle the new Node data.
    • Implemented necessary function bindings for node management in Go.

  3. Testing:

    • Added new test cases in Solidity to cover the new node management functionalities.
    • Renamed test contract from CounterTest to GroupMessagesTest and added NodesTest for comprehensive testing of node functionalities.

vm.prank is cool. It just lets you change the msg.sender value to any other address for a test, so you can impersonate someone and see how the contract behaves.

Using ERC721 is a smart idea. Will ecosystem tools break if we don't specify base/token URI? I suppose we could also generate some fun images too. Also do we need to block safeTransferFrom?

We should not allow a node to have node ID 0, because an originator SID of 0 means that the originator is the blockchain. Wondering if we should pre-increment _nodeIdCounter rather than post-incrementing it?

I have a comment somewhere about this. I kinda think we should start at 1000 just to be safe. Would let us partition the smart contracts later if we wanted to.

Small nit, any reason this one uses a require statement, but updateHealth uses public onlyOwner?

Only that I wanted a better error message, but agree the inconsistency feels weird

I wonder if there are tradeoffs to allowing/encouraging nodes to update the HTTP address at any point, rather than going through a more heavyweight process via the DAO? For example, ensuring there is a graceful failover etc. Don't have a super strong opinion here

I don't really know. Wondering the same thing. Worth a discussion.

Will ecosystem tools break if we don't specify base/token URI?

The OpenZeppelin default just sets it to "". I would expect tools to handle that, since some generative NFTs are on-chain only. But I'm with you that at some point we'll do an extra-credit project and make a URI that has JSON metadata with a fun image and more info. Then it fully looks like a normal NFT.

Also do we need to block safeTransferFrom?

safeTransferFrom calls transferFrom internally, so we get them both with this override.
