 The _How-to_ guides in the _Offchain workers_ category illustrate common use cases for offchain operations.

+It is important to note that offchain storage is separate from on-chain storage.
 You can't send data collected or processed by an offchain worker directly to on-chain storage.
 To store any data collected or processed by an offchain worker—that is, to modify the state of the chain—you must enable the offchain worker to send transactions that modify the on-chain storage system.
-For examples of how to prepare an offchain worker to send transactions, see [Add offchain workers](/tutorials/build-application-logic/add-offchain-workers/).

 Because most blockchains can't access data that's hosted on servers outside of their own network, they typically use external third-party services—**oracles**—to pull information in from or push information out to locations that are outside of the network.
 For Substrate-based blockchains, **offchain workers** (OCW) provide similar capabilities, but with the advantage of being able to access on-chain state.
