How to build your first blockchain on Substrate?

cointelegraph.com:

When Ethereum was launched in July 2015, the world was introduced to the concept of smart contracts that hoped to revolutionize the blockchain space and allowed anyone from developers to enthusiasts to deploy decentralized applications (DApps) on the Ethereum mainnet. 

With various DApps currently in use across different blockchains like Ethereum, they offer many use cases including banking, gaming, finance, online shopping and social media, with an ever-expanding user base across the globe.

Having provided the infrastructure needed for developers to create innovative digital applications, Ethereum, however, has limitations such as limited scalability and high gas fees, factors that are now inhibiting developers from building specialized solutions that can rival popular centralized platforms like Twitter, Facebook and Netflix.

To overcome these challenges and explore the possibilities of blockchain technology, Ethereum co-founder and its first chief technology officer Gavin Wood left the Ethereum Foundation and founded Parity Technologies to build blockchain infrastructure that can help create the foundation of a decentralized web, or Web3 as it is known.

Armed with a vast industry experience and deep understanding of creating blockchains, he went ahead to build Substrate as an open-source and future-proof blockchain framework for developers to build on, enabling them to tweak their blockchain’s architecture in line with changing customer preferences.

Substrate-based blockchains can be integrated as parachains on networks such as Polkadot or Kusama and provide a high level of interoperability, helping to bring to market truly decentralized real-world solutions that
