# Celo Validators

Secure the Celo network by participating in the consensus of the Celo protocol.

<Warning>
  This page describes the historical Celo Layer 1 blockchain. It is useful for understanding Celo’s history, but does not reflect the current state of the network. As of block height 31,056,500 (March 26, 2025, 3:00 AM UTC), Celo has transitioned to an Ethereum Layer 2.
</Warning>

***

Celo Validators participate in the consensus of the Celo protocol. They help secure the Celo network by verifying transactions and proposing blocks to add to the Celo blockchain.
