#ETH #Fusaka Ethereum launches Fusaka upgrade: 8x more data, instant transactions, and a new level of UX - Cointelegraph

🔥 Ethereum has successfully activated its second major upgrade of 2025 — Fusaka, marking a true breakthrough in network scaling.

⚪️ The key feature — PeerDAS (peer data availability sampling) — increases Rollup throughput by 8x, reduces fees, and paves the way for an “instant user experience.”

🕓 The upgrade went live on the Ethereum mainnet at 21:49 UTC, December 3, at epoch 411392.

According to the Ethereum Foundation, Fusaka is a step toward a new level of interaction with the network:

“Fusaka-based pre-confirmations reduce transaction latency from minutes to milliseconds. This opens the door to new use cases and significantly improves the user experience.”

What’s changing:

🟠Rollups can transmit 8x more data with less load on nodes.

🟠Fees for “blobs” are reduced, making work easier for L2 projects.

🟠Decentralization increases: nodes download less data while preserving network integrity.

🟠A foundation is created for further increasing the gas limit.

✅ In simple terms: L2 networks will now be able to operate faster, cheaper, and at greater scale — all without compromising security.

AR’s opinion: Fusaka is an upgrade that could become a catalyst for new ETH growth. Infrastructure upgrades rarely reflect immediately in price, but they lay the groundwork for the next bullish impulse. Fusaka launches a phase of real Ethereum scaling. Forecasts are already being made: “Pectra gave +58% for ETH — Fusaka will give more.” Given the hype and fundamental improvements, this scenario looks quite realistic, especially amid growing interest in L2 and the DePIN segment.
