What is Phase 2 of Ethereum 2.0?

Phase 2 of Ethereum 2.0 is the final stage in the transition to a more scalable and sustainable Ethereum network. It involves the introduction of sharding chains, enabling parallel transaction processing and increasing the network's capacity. Additionally, Phase 2 aims to integrate the old Ethereum 1.0 chain into the new system and enhance cross-shard communication and transaction functionality.
