Fusaka Upgrade Live Dec 3 — PeerDAS, Bigger Gas Limits and What Traders Should Watch
Ethereum will activate the Fusaka mainnet upgrade on December 3, introducing Peer Data Availability Sampling (PeerDAS), support for R1-curve cryptography and EIP-7951 (improved mobile passkeys), plus EIP-7825 which caps single-transaction gas at about 16.8M. Node operators will see a staged increase in block gas target (initially to 60M with further capacity rollouts on Dec 9 and Jan 7) after successful testnets (Holesky, Sepolia, Hoodi). Developers, node operators and wallet providers are urged to update and test software ahead of each rollout window. Expected protocol effects include higher data throughput for rollups, lower congestion and fees, and increased blob throughput; EIP-7825 may require complex contracts to adapt. Markets showed a mixed-to-positive reaction: ETH price briefly rebounded and technical commentary cited a break of a prior descending channel with the $3,000 area acting as newly tested support. Short-term sensitivity remains high around key EMAs and the $3,000 level; traders should monitor actual on-chain throughput, gas-usage patterns, node/wallet upgrade progress, exchange netflows and fee dynamics to time entries and manage risk. Overall, the upgrade reduces structural congestion risk (positive for on-chain activity) but creates short-term event risk tied to adoption and software readiness.
Bullish
Fusaka materially increases on-chain capacity and rollup data throughput via PeerDAS and a stepped block gas uplift, which should reduce congestion and lower fees — structural improvements that support higher on-chain activity and demand for ETH in the medium-to-long term. The staged rollout and required client/wallet updates introduce short-term execution risk; if adoption or software bugs delay benefits, price could be pressured. Near term, market reaction is mixed: technical breaks above a descending channel and the $3,000 area acting as support are constructive, but EMAs and exchange netflows point to sensitivity. For traders, the net effect is bullish for ETH over weeks to months if rollouts proceed smoothly and throughput increases as expected; nevertheless, event risk around node/wallet upgrades and initial gas pattern changes can create short-term volatility and possible pullbacks. Monitor upgrade adoption metrics, actual gas usage and fee trends, exchange flows, and on-chain rollup performance to confirm the bullish thesis or manage downside risk.
