What is Metachain (Elrond Network)?

The Metachain operates like a control center for Elrond and is designed to run within its own specialized shard to allow communication with other shards and carry out cross-shard operations within the Elrond Network. The Metachain's main purpose is not to process transactions, but instead to notarize and finalize shard block headers, store and maintain the network's validator registry, trigger new epochs, and process various tasks for fishermen.
