Bonded Proof of Stake
Web3 / mining staking
Bonded Proof of Stake is a consensus mechanism where validators must lock up cryptocurrency collateral to participate in block validation, while token holders can delegate their stake to validators through bonding. Both validators and delegators are economically incentivized to act honestly because misbehavior results in their bonded tokens being slashed or forfeited. This creates a financial penalty system where all participants share responsibility for network security, aligning individual incentives with network health.
Example
Cosmos uses Bonded Proof of Stake where validators bond ATOM tokens and delegators bond their ATOM to validators; any validators caught double-signing or downtime face automatic slashing of their and their delegators' stakes.
Why It Matters
Bonded PoS democratizes validator participation by allowing smaller token holders to earn staking rewards through delegation while maintaining security through shared financial risk and economic penalties for dishonest behavior.
