IPCM is a smart contract that points to an IPFS CID which can be updated onchain, providing a simple solution to dynamic offchain data using IPFS

IPFS has been the go-to decentralized network for sharing content and websites. However it's greatest strength, immutability, is also it's greatest weakness. There are cases where you might need to update content on IPFS, but that would result in a new CID. IPCM (InterPlanetary CID Mapping) aims to solve this by storing a simple IPFS string onchain and letting the contract be the point of reference for the latest state. Benefits include:

A simple example IPCM is for static webhosting on IPFS, where you can update the IPFS reference onchain without having to deal with the compliexities of IPNS. Check out the more detailed example below

It is preferable to setup an account with cast or another secure method instead of using the private key in plain text. Please practice safe key management!
