What is Ethereum?

Summary

• Ethereum is technology building apps, w/o controlling of central authority

What is a cryptocurrency?

• Crypto: new form of digital money, powered by cryptography
• It is different from normal bank, because there is no middle man –> but how? 🤨
  • middle man: central authority that intervenes a tx between the sender and recipient
    • they surveil, censor, revert
• However, it directly connects sender and recipient w/o having to deal w/ any central authority
  • Nobody else will have access to your funds
  • Nobody can tell you what services you can use

What is a blockchain

• Blockchain is a DB of tx
• we can only ‘add’ data, but cannot remove.

Why is it called crpytocurrency

• Blokchain uses cryptographic techniques to ensure that funds are safe.

What is the difference between Ethereum and Bitcoin

• Both provide digital money w/o central authority
• Ethereum is programmable: can build and deploy –> but how? 🤨

What can Ethereum do?

• Banking for everyone: only needs internet connection
• A more private internet: we don’t have to provide all your personal detail
• A peer-to-peer network: intermediary company is not needed
• Censorthip-resistant
• Commerce guarantees: secure + rules that won’t change
• All products are composable: all apps are built on the same blockchain, they share global state

Why would I use Ethereum

• Cheaper and faster crossborder payments: many stable coins are built on Ethereum network
• The quickest help in times of crisis: such as crisis, war, etc –> do they really use it? 🤨
• Empowering creators: platforms such as Spotify, Youtube, and Etsy
• Empowering gamers: incentivized by in-game tokens for real money. That token is built on Ethereum network.
