## What is the Composition of Validator Set?

A validator set refers to the collection of entities responsible for proposing and validating new blocks, reaching consensus, and maintaining the integrity of a Proof-of-Stake (PoS) blockchain network. These validators typically stake a significant amount of the network's native cryptocurrency as collateral, demonstrating their commitment. The size and decentralization of this set are critical factors in the network's resilience. Selection criteria often involve reputation and stake size.

## What is the Function of Validator Set?

The primary function of the validator set is to ensure the security and liveness of the blockchain by participating in the consensus mechanism. They verify transactions, create new blocks, and attest to the validity of the chain's state. Validators are incentivized with block rewards and transaction fees for honest participation, while malicious behavior can result in the slashing of their staked collateral. This economic mechanism enforces good behavior.

## What is the Security of Validator Set?

The security of a PoS blockchain, and by extension, the decentralized finance and derivatives applications built upon it, directly depends on the integrity and decentralization of its validator set. A sufficiently large and diverse set makes it economically prohibitive for any single entity or cartel to gain control and compromise the network. Robust slashing mechanisms deter malicious actors, ensuring the reliability of on-chain data for derivatives settlement and oracle feeds.
