Every VerusID has an on-chain key-value store called the contentmultimap. These demos show what you can build with it — no smart contracts, no external databases. Just data on the chain.
Every VerusID has a built-in on-chain data store. It's a map of VDXF keys to arrays of values — each value up to ~4KB. Think of it as a blockchain-native key-value database attached to your identity.
Data can be public or encrypted. You control who can read it by sharing viewing keys selectively. Updates happen through updateidentity — a single RPC call.
# Write data to your identity ./verus updateidentity '{ "name": "yourname", "parent": "iParentIdHere", "contentmultimap": { "iVDXFKeyHere": ["hex-encoded-data"] } }'
