Proof of Stake (PoS)
A decentralized consensus mechanism where validators are chosen based on the amount of cryptocurrency they "stake" or hold in their wallets. Efficient, secure, and sustainable.
Jump to MechanicsWhat is PoS?
Proof of Stake (PoS) is a method for achieving distributed consensus. Instead of relying on computational power, validators are chosen to forge new blocks based on the amount of cryptocurrency they "stake" as collateral.
More DetailsValidator Selection
Validators are chosen to forge new blocks based on their stake and a complex randomization algorithm. The greater the stake, the higher the chance to validate a block and earn rewards.
Understand SelectionHow PoS Works
Staking
Validators lock up coins as collateral to participate in forging new blocks. The more they stake, the higher their selection chance.
Validation
Once selected, a validator signs the block and adds it to the chain. The process is secure, energy-efficient, and fair.
Reward
Validators earn transaction fees and block rewards. The more they stake and validate, the more they can earn.
Why PoS is Superior
Energy Efficiency
PoS eliminates the need for computationally-intensive mining, reducing energy consumption by up to 99% compared to PoW.
Stronger Security
Attack costs are prohibitively high for bad actors since malicious behavior forfeits the staked crypto—introducing "nothing-at-stake" security.
Decentralization
PoS supports equal participation from smaller investors. Users with any amount of stake can join a decentralized, democratic consensus.
Challenges and Considerations
Nothing-at-Stake ⚠️
While secure, PoS theoretically allows validators to validate on conflicting chains without economic risk. This is mitigated with slashing penalties for invalid behavior.

High entry barriers exist in certain PoS systems due to large initial staking requirements. Pooled staking and staking services are helping to address these concerns.
