🔐 Distributed Consensus

Achieving agreement in distributed systems. Learn how nodes synchronize and maintain consistency.

What is Consensus?

Consensus is the process by which network participants agree on a single data value or state. This is crucial in distributed systems to ensure all nodes maintain consistent data despite possible communication failures.

  • ✅ Enables fault tolerance in decentralized systems
  • 🌐 Fundamental in blockchain and distributed databases
  • ⚙️ Resolves conflicts in network communications

Proof of Work (PoW)

Miners solve complex mathematical puzzles to validate transactions and reach consensus. It ensures security through computational effort.

Proof of Stake (PoS)

Validators are chosen based on the amount of cryptocurrency they hold. Consensus is reached by economically incentivized validators.
