I am not sure if this applies, but is the concept similar to blockchain... All the data is with everyone and still within your machine as well. Meanwhile, if the machine is disconnected then reconnect and update with other users.
No; its not like blockchains. The data isn't with everyone. Its just on your devices.
Think about email. Your emails aren't on everyone's devices. They're just on your devices. If you go offline, you can still read and reply to emails. But the emails you send won't actually get sent until you go online again. Its like that; but instead of sending messages back and forth, you can edit things and the changes you make get synced while you're online.
