Ethereum News Today: Fusaka Upgrade for Ethereum: Achieving Scalability While Maintaining Security and Decentralization

The Fusaka upgrade for Ethereum, a significant milestone in the platform’s journey to greater scalability, has passed its last testnet hurdle and is now set for a mainnet release on December 3. Currently live on the Hoodi testnet, this upgrade brings a collection of

Improvement Proposals (EIPs) aimed at boosting transaction speed, security, and efficiency, giving the blockchain a stronger position against high-performance competitors such as and , according to a .

Fusaka’s deployment on Hoodi follows earlier successful launches on the Holesky and Sepolia testnets in October. Developers have outlined a three-phase mainnet rollout: an initial launch, an increase in blob storage capacity, and a subsequent hard fork to further expand the network. This step-by-step strategy highlights Ethereum’s focus on gradual upgrades to limit risks to the live chain, as noted by

.

A key feature of Fusaka is EIP-7594, which brings Peer Data Availability Sampling (PeerDAS) to the network. This mechanism lets validators check only small pieces of data rather than entire blobs, cutting node costs and improving data access for Layer 2 solutions. Other proposals, like EIP-7825 and EIP-7935, will raise the gas limit and allow smart contracts to run in parallel, potentially increasing Ethereum’s throughput to 12,000 transactions per second (TPS) from the current 3,100 TPS, as outlined by

.

This upgrade also fits within Ethereum’s larger "Surge" plan, which aims to scale the network without sacrificing security or decentralization. Co-founder Vitalik Buterin has consistently highlighted the "blockchain trilemma"—the challenge of balancing scalability, security, and decentralization—and Fusaka is a major move toward addressing this issue. The update comes after June’s Pectra release, which improved staking and wallet features, and before the next big step, Glamsterdam, expected in early 2026, as also mentioned by CryptoRank.

Market sentiment following the testnet’s success has been cautiously positive. As of October 25, Ethereum (ETH) was trading at $4,021, with its 50-day simple moving average (SMA) at $4,229, signaling short-term strength. Analysts at VanEck believe Fusaka could enhance Ethereum’s monetary characteristics by lowering Layer 2 fees, driving more economic activity, and strengthening the base layer’s security. Some analysts, including XWIN Research and BitMine’s Tom Lee, have set a price target of $10,000 for

in the current cycle, while others like The Long Investor see the potential for $13,500 by 2029, according to .

On-chain metrics also point to rising confidence among major holders. Santiment has observed that "whales" (wallets holding between 100 and 10,000 ETH) have resumed accumulating, reversing previous selling trends. This accumulation, along with Ethereum treasury organizations surpassing their

counterparts in supply dominance, underscores growing institutional interest in Ethereum’s future after the upgrade, as reported by .

With the mainnet activation scheduled for December 3, attention is turning to whether the upgrade will drive wider adoption and price growth. By tackling key scalability challenges and paving the way for Glamsterdam, Fusaka could mark a turning point for Ethereum’s place in the decentralized landscape.
