#### Off-chain Activities

Off-chain Activities consist of the same types of content and reactions available in OpenActions and OpenReactions, except they are stored off-chain.  

#### On-chain / Off-chain 

OpenSocial provides Web3 dApps with the flexibility to store content created and reactions by users either on-chain (i.e. OpenActions and OpenReactions) or off-chain (Off-chain Activities). All Off-chain Activities are stored under decentralised storage system like IPFS or OrbitDB.

Web3 dApps can freely decide whether to store content on-chain or off-chain and subsequent reaction on-chain or off-chain.
