Sharding is Ethereum’s secret weapon to scaling its network. By 2025, Ethereum will be fully sharded, meaning the blockchain will be broken into smaller, manageable pieces or “shards.” This will dramatically increase Ethereum’s transaction capacity without compromising decentralization.

Key Impact:

Massive Scalability: Ethereum could process thousands, if not millions, of transactions per second (TPS).
Reduced Gas Fees: Sharding will ease network congestion and reduce fees, making it more affordable for developers and users.
