ByteByteGo·4yEP18: Build a chat application. Also...
The diagram is based on the tech talk by Jessica Tai. The micro service architecture focuses on the unification of APIs. With blockchains, we can merge wallet services from different banks into one global service. The diagram below shows how we can leverage the pub-sub functionality of Redis to develop a chat application.

Hacker News·4yWeb3 is centralized (and inefficient!)
Web3 platforms are in fact centralized, just as Web2 was. Web3 firms are for-profit businesses, and so are the VC firms backing them. You can easily run Nextcloud from your old PC instead of subscribing to Dropbox, but you can’t easily host a “dApp” on your MacBook instead of the public blockchain.
Hashnode·4yGetting Started with Ethereum and Solidity
Smart contracts are just like physical paper contracts except they don't need manual work to execute them. All the instructions are automated and these instructions get executed when certain conditions are met. Solidity is programming language which is needed to write smart contracts.
