Ethereum upgrades, known as "hard forks," enhance the blockchain's functionality, scalability, and security. Key upgrades include Ethereum 2.0, transitioning from Proof of Work to Proof of Stake, reducing energy consumption and enabling sharding for improved scalability. The Merge in 2022 integrated the Beacon Chain, finalizing the shift to Proof of Stake. Subsequent upgrades like Shanghai enabled staked ETH withdrawals, while Dencun introduced data blobs to lower Layer 2 costs. These upgrades boost transaction speed, reduce fees, and support Ethereum’s vision of a decentralized, scalable ecosystem, fostering innovation in DeFi, NFTs, and smart contracts.
