Blockchain at a fundamental level maintains trust.

Blockchain is Immutable Distributed Ledger

It works on a peer-to-peer network


  1. Replication
  2. No Central Authority
  3. Irreversibility
  4. Accessibility
  5. Time-stamping
  6. Cryptography

Block Chain Use Cases:-

  • Central Bank Digital Currencies (CBDC)
  • Digital Identity

Ethereum & Smart Contracts:-

  • Ethereum is a decentralized platform design to run smart contracts.
  • ==> Resistant to censorship.
  • ==> Distributed server.
  • Ethereum maintains a native asset called ether that is the basis of value in the Ethereum ecosystem.

What is a Smart Contract?

In Ethereum, smart contracts are executed by network itself!

  • Network consensus removes need for Trusted Third Party.
  • Violation of contracts requires subverting the entire network.
  • Allows fir secure peer-to-peer agreements that live on the blockchain forever.

Contracts in Ethereum are like autonomous agents that live inside of Ethereum network.

  • React to external world when "poked" by transactions (which call functions)
  • Have direct control over (i) internal ether balance (ii) internal contract state (iii) permanent storage
