Off-chain

Definition:

When digital data is stored off a blockchain, for example on a central server, it is considered off-chain. Some NFT projects store the data of their projects this way on decentralised servers like IFPS (Interplanetary File System), but it can incur large long-term costs and be at risk if the server goes down.

“Be careful of off-chain storage. The blockchain might outlive your server.”
