Proof-of-Validation

Understanding Proof-of-Validation

Proof-of-Validation (PoV) is a unique consensus mechanism called proof-of-stake (PoS). It functions by utilizing validator nodes to achieve consensus. In a PoV system, each node maintains a complete record of transaction sequences stored in blockchain blocks. Furthermore, all user accounts can be linked to a user’s public key and the crypto token owned by the node.

In PoV, users have the choice to stake their coins within validator nodes. The number of nodes a validator possesses is determined by the amount of tokens staked.

To validate a new block, a group of validators with at least two-thirds of the network’s total voting power must send a commit vote. This ensures that PoV protocols are secure against Byzantine faults, remaining secure as long as one-third or fewer of the network’s nodes are compromised.
