POS
What is POS (Proof of Stake)?
Proof of Stake (POS) represents a significant evolution in blockchain consensus mechanisms, designed to enhance speed and efficiency while reducing operational costs. Unlike the traditional Proof of Work system that relies on miners solving complex mathematical problems—a process that is both resource and energy-intensive—POS takes a different approach.
Transaction Validation through Staking: In POS, transactions are validated by network participants who stake their tokens. This staking process is crucial as it serves two main functions:
Selection for Transaction Processing: Similar to mining, staking determines which participant gets to add the latest transactions to the blockchain.
Ensuring Block Validity: Stakers play a key role in confirming the legitimacy of blocks added to the blockchain.
Voting with Tokens for Security: The implementation of POS may vary across different blockchain projects, but the core principle remains consistent. Stakers use their tokens to vote, contributing to the blockchain's security. Their staked tokens act both as a pledge of good faith and as a deterrent against breaking the network's rules.
