Blockchain Consensus Mechanisms

Discover the fundamental consensus algorithms that secure decentralized networks—how blockchains agree on state without a central authority.

The foundational algorithm behind Bitcoin. Miners compete to solve cryptographic puzzles to validate transactions. Secure but energy-intensive.

Learn PoW

Validators are chosen based on wealth (stake) to create new blocks. Energy-efficient alternative to PoW, used by Ethereum 2.0 and others.

Explore PoS

Staked token holders vote for representatives. Efficient scalability solution with fast transactions, ideal for community-driven blockchains.
