#ETHETFS Ethereum (ETH) has undergone several important upgrades aimed at improving the performance, security, and scalability of the network. One of the most notable upgrades is **Ethereum 2.0** (Eth2), also known as **Serenity**, with the goal of moving from Proof of Work (PoW) to Proof of Stake (PoS) consensus mechanism ). The first phase of Eth2, **Beacon Chain**, was launched in December 2020, introducing PoS and managing validators.

Next, the **London** upgrade in August 2021, highlighted by EIP-1559, changed the transaction fee mechanism, introducing base fees and an ETH burn mechanism, helping to reduce the inflation of ETH. Then **Altair**, an upgrade to the Beacon Chain, launched in October 2021, improving the security and synchronization of the chain.

Another important step is **The Merge**, expected to be completed in 2022, merging the current PoW chain with the Beacon Chain PoS, officially transitioning the entire Ethereum network to PoS. The next **Shanghai** and **Capella** upgrades will focus on improving performance and adding new features.

These upgrades not only make Ethereum more secure and efficient, but also increase scalability, lower transaction costs, and reduce the network's environmental impact. These ongoing upgrades demonstrate the commitment of the Ethereum community and developers to maintain and enhance the network's competitiveness in the cryptocurrency ecosystem.
