Ethereum’s network and its possibilities, by contrast, are always changing. Ethereum developers have fueled a proliferation of use cases, including the rise of decentralized exchanges (DEX), stablecoins and non-fungible tokens (NFT). Ethereum’s successful transition to PoS (aka “the Merge” in September 2022) marked a major milestone in the history of blockchain. Looking ahead, the network will undergo several new upgrades, including the Shanghai upgrade in March and sharding thereafter (both are expected to ease network congestion and establish the prerequisite for major adoption). The future of Ethereum is more exciting than ever, and the growth of layer 2 systems (i.e., Polygon, ZK rollups, Optimism and Arbitrum, to name a few) will further enhance Ethereum’s scalability.
