โ๏ธ What is a consensus mechanism? Blockchain's voting rules
Current Fear and Greed Index: 25
Consensus mechanism = Blockchain's "voting rules" that decide who gets to write the block, it's the cornerstone of the entire system.
Why do we need consensus?
Blockchain is decentralized, so there's no bank acting as a middleman. So how do we keep the books? Who ensures no one cheats? That's the problem the consensus mechanism aims to solve.
Detailed breakdown of mainstream types:
1๏ธโฃ PoW (Proof of Work) โ used by Bitcoin
โข Principle: Miners compete with computational power to solve puzzles, the first one to solve gets to write the block
โข Advantages: Highest security, validated over 14 years
โข Disadvantages: Huge energy consumption, Bitcoin's annual consumption exceeds that of Norway
โข Representatives: Bitcoin, Litecoin
2๏ธโฃ PoS (Proof of Stake) โ used by Ethereum
โข Principle: Staking tokens grants validation rights, the more you stake, the higher your chance
โข Advantages: 99.95% energy efficient, fast
โข Disadvantages: The rich get richer, the more you stake, the more power you have
โข Representatives: Ethereum, Solana, Cardano
3๏ธโฃ DPoS (Delegated Proof of Stake)
โข Principle: Token holders vote to elect representatives to write the block
โข Advantages: Extremely fast
โข Disadvantages: Higher degree of centralization
โข Representatives: EOS, TRON
Future trends:
After Ethereum's transition from PoW to PoS, the whole industry is moving towards energy efficiency. However, the security of PoW remains irreplaceable; Bitcoin will likely always use PoW.
