Stake Pool Delegation#

Stake pool delegation allows users to participate in Cardano's consensus protocol by delegating their stake to a pool that produces blocks. By integrating stake pool delegation into your application, you enable users to earn rewards while supporting the network's security and decentralization without requiring technical expertise in running validator nodes.
