## Leader Election

Leader election is a critical consensus process in decentralized networks where nodes determine which participant is authorized to propose the next block of transactions. This mechanism prevents multiple nodes from creating conflicting blocks simultaneously, ensuring the integrity of the distributed ledger.

In a proof of stake system, this is often randomized to prevent monopolization of block production by a single entity. The chosen leader broadcasts the new block to the network, which then verifies the proposal before adding it to the chain.

By selecting a unique leader, the protocol maintains order and synchronizes the state across all global participants. This process is fundamental to the efficiency and security of financial settlement layers.
