Ethereum: “Fusaka” to make the network faster starting in December
- Ethereum will receive a major update called Fusaka on December 3, 2025. It will be tested on test networks starting in October before going live on the mainnet in December.
Important decisions were made on today's Ethereum developer call, ACDC #165. Developers confirmed the public testnet schedule and BPO hard fork schedule for Fusaka.

- For end users, little will change at first. The update focuses on Ethereum's backbone, making the network faster, cheaper, and more stable. The capacity for so-called “blobs”—data packets that are especially important for Layer 2 networks like Arbitrum or Optimism—will be more than doubled. This makes these solutions more affordable and more powerful.
- Developers are already discussing a significant increase in gas limits, which could allow Ethereum to achieve thousands of transactions per second in the long term—many times more than today. A new technology called PeerDAS allows nodes to process less data at once. This reduces hardware requirements and allows more people to participate in the network.
- Many had criticized Ethereum's reliance on external solutions (Layer 2). Fusaka now strengthens the network's base layer and makes it more resilient overall.
- Ethereum is tradable on Bitpanda. Users can buy and sell the cryptocurrency there securely and reliably.
