Tag: Proof of Work

Learn how blockchain consensus mechanisms like Proof of Work, Proof of Stake, PBFT, and DPoS keep decentralized networks secure and in sync. Understand their trade-offs in speed, energy use, and decentralization.

The Ethereum difficulty bomb was a hidden timer designed to force the network’s switch from energy-heavy mining to Proof of Stake. It worked-by making mining so slow and expensive that change became unavoidable.
