Ethereum's 'Fusaka' Era: Has the Jan 2026 Upgrade Finally Made ETH 'Ultrasound' Again?
Following the mainnet activation on December 3, 2025, the Ethereum network entered its final phase of the Fusaka upgrade on January 7, 2026. By introducing a revolutionary "Blob Parameter Only" (BPO) mechanism and a minimum fee floor, Fusaka has successfully stabilized the fee market.
