In this video, we'll create, test, & deploy a proof of existence chain in 30 minutes by using the Substrate blockchain framework. By the end, you’ll:
- Release a blockchain into the wild
- Run a node for it
- Interact with your logic using a simple UI
The only requirements are a basic understanding of smart contract development.
Code along at the Substrate Playground: playground.sub...

CORRECTION: Decl_storage
In the video we explain the storage access prefix is the Module name, which is only sometimes the case. In the specific context of how it is used, it determines the "storage prefix" where your modules storage items are so its name can actually be different than your module.
Basically you can’t always access a storage with ModuleName::StorageItem.
However, you CAN always access it using my_pallet_crate::StorageItem.
