Hi all,
Just wrapped up releasing a new version of an on-chain metadata registry that allows deployment keys to link IPFS hashes to contract addresses. Users can also self-attest to a piece of data.
In this latest release, categories have been added so that there is a many-to-one relationship between IPFS multihashes and ethereum addresses. This is so dapps can also begin to share data with one another and possibly use the platform as a light reputation layer.
Calling all Solidity wizards to break the implementation and the governance rules laid out in the documentation 
Any feedback or suggestions are more than welcome! Caching layer coming soon…
