# Validator

In the GEB framework, validators are the core participants of the blockchain network, primarily responsible for the following tasks:

1. **Block Production**: Generating new blocks through consensus algorithms (such as Aura, Babe) to maintain the continuity of the chain.
2. **Transaction Validation**: Checking the legitimacy of transactions to prevent double-spending or invalid transactions from being included in the chain.
3. **Network Security**: Participating in network consensus by staking tokens (Staking) to ensure the irreversibility and attack resistance of the chain.
4. **Finality Confirmation**: In the GRANDPA consensus, validators vote to confirm the final state of blocks, ensuring the consistency of the chain.

Meanwhile, GEB has pioneered a dual-token staking model, using both L-BTC and GEB tokens for validator staking. This allows users to contribute to chain security while simultaneously increasing their returns.
