The Governance Council and the Core Team serve similar roles in the Klaytn blockchain. The Governance Council is responsible for the implementation of major decisions on the blockchain, and they are granted voting rights due to their large percentage of coins. This makes the Governance Council similar to a Decentralized Autonomous Organization (DAO), as they are responsible for the same type of decision-making. While the Core Team still has a role in the Klaytn blockchain, the Governance Council is responsible for the major decisions that shape the platform.
