Today I'm excited to release IPCM: InterPlanetary CID Mapping, a smart contract solution for dynamic IPFS data. 

IPCM is a simple smart contract that stores an IPFS CID reference which anyone can read but owner the owner of the contract can update it. 

Something we encountered quite a bit at Pinata is user frustration with updating content on IPFS. For images or json files it just meant re-uploading the file and getting a new CID. However for websites shared on IPFS it was way worse. Today solutions like IPNS exist but prove to be slow, complicated, and lack an accessible history. 

With IPCM you can update the CID reference on the contract, then anyone can read it. The contract uses the Ownable extension so only the owner of the contract can write to it, giving a level of identity tied to the content being updated. There is also an event fired every time the content is updated, so if indexed with a tool like Ponder you can have an onchain version history.

IPCM is MIT licensed and open sourced
