Web3 Foundation's Technical Educator, Logan Saether explains the relationship between Rust, [Substrate](https://ww.substrate.io/) and [Polkadot](https://polkadot.network/).

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: https://playground.substrate.dev/ Questions? Ask in the Substrate Technical chat on Riot: https://riot.im/app/#/room/!HzySYSaIhtyWrwiwEV:matrix.org CREDITS: Video by Nicole Zhu. Based on the tutorial by Shawn Tabrizi: https://substrate.dev/docs/en/next/tutorials/build-a-dapp/prepare#about-proof-of-existence Substrate Playground created by Julien Eluard. Substrate is created by Parity Technologies. Learn more about Substrate at https://substrate.dev.

Polkadot is a next-generation blockchain protocol connecting multiple specialized blockchains into one unified network. Designed as part of a broad vision for a web that returns control to individuals over internet monopolies, Polkadot builds on the revolutionary promise of previous blockchain networks while offering several fundamental advantages. What are those advantages? Polkadot enables blockchain networks to: scale, specialize, work together, self-govern, upgrade easily and more.
