Ethereum developers have announced that the highly anticipated Fusaka upgrade is set to go live on December 3. The announcement came after the update successfully passed its third and final testnet this week, marking a crucial milestone in its deployment.
Fusaka aims to significantly enhance the scalability of the Ethereum network by refining how it collects and verifies data from layer-2 chains, building on advancements made in earlier updates. Central to this upgrade is a new data-sampling method called PeerDAS, which is expected to dramatically increase the speed and reduce the costs of layer-2 transactions. This enhancement expands blob space in each Ethereum transaction block, a concept introduced in the previous Dencun upgrade that efficiently allowed temporary storage of layer-2 data.
Alex Stokes, the Ethereum developer who facilitated the meeting in which the upgrade was confirmed, highlighted the excitement surrounding Fusaka within the community, calling it “a really big deal.” Supporters believe that the improvements Fusaka will bring could play an instrumental role in paving the way for Ethereum’s broader adoption as a global platform for on-chain transactions.
Vitalik Buterin, Ethereum’s co-founder, has emphasized the significance of PeerDAS, describing it as “the key to layer-2 scaling.” He argues that with this update, Ethereum is a step closer to its long-term goal of making on-chain transactions more accessible and affordable for users worldwide.
While the Fusaka upgrade holds considerable promise, there remains uncertainty regarding its impact on the price of Ethereum (ETH). Currently, ETH has experienced a weekly decline of approximately 2.3%, trading at around $3,760. In the aftermath of Ethereum’s previous upgrade, Pectra, the cryptocurrency saw a notable surge of nearly 29%, coinciding with favorable macroeconomic conditions.
In a prediction market operated by Decrypt’s parent company Dastan, users suggest a stronger likelihood for ETH to reach $4,500 rather than dropping below $3,100, though the confidence level is not overwhelmingly one-sided—currently sitting at 61% to 39%.
As the December launch date approaches, all eyes will be on the Ethereum network, eagerly anticipating the potential transformations that the Fusaka upgrade could bring to the landscape of blockchain technology and digital finance.
