Ethereum Fusaka Upgrade: December Launch Triples Gas Limit
Ethereum’s Fusaka Upgrade passed the Holesky testnet on October 1 and is slated for mainnet activation on December 3. This Fusaka Upgrade will triple the per-block gas limit from 45 million to 150 million, aiming to boost throughput and network capacity. Key innovations include PeerDAS, which lets nodes verify data samples instead of full blobs, and Verkle Trees, reducing storage requirements. Together, these features lower Layer-2 gas fees, speed up rollup transactions, and enhance on-chain efficiency for DeFi and NFT users. The upgrade will first deploy on Sepolia and Hoodi testnets ahead of mainnet launch. Market reaction has been positive: ETH jumped nearly 5% after Holesky, and futures open interest rose 4% in 24 hours. By enabling cheaper rollups and higher fee burns, the Fusaka Upgrade could trigger bullish momentum for ETH.
Bullish
The Fusaka Upgrade’s successful testnet trials and planned December launch have already spurred a near 5% ETH price rally and a 4% rise in futures open interest, reflecting traders’ bullish anticipation. In the short term, the upgrade’s features—tripling the gas limit and cutting Layer-2 fees via PeerDAS and Verkle Trees—are likely to drive higher trading activity and fee burns, providing immediate support. Over the long term, enhanced throughput, lower transaction costs, and increased network demand should reinforce Ethereum’s competitiveness and value proposition, underpinning sustained price gains.
