Ethereum Completes Prague Upgrade (EIP-4844 Fully Activated)**\n- Ethereum’s long-anticipated Prague hard fork successfully activated on April 5, 2026, completing the full implementation of EIP-4844 (Proto-Danksharding). This marks a critical step toward Ethereum’s scalability roadmap, reducing Layer 2 transaction fees by up to 90%. Rollups on Optimism, Arbitrum, and zkSync reported immediate cost reductions, with average batch submission fees dropping from $120,000 to under $12,000. The network processed over 2.1 million blob-carrying transactions in the first 48 hours.\n- Source: [ethereum.org/prague-upgrade-2026](https://ethereum.org/en/roadmap/prague/)*\n- 2.
