The post ‘It’s a Really Big Deal’: Ethereum Developers Set Final Date for Fusaka Upgrade appeared on BitcoinEthereumNews.com.

In brief Ethereum developers have officially scheduled the Fusaka upgrade for December 3, following a successful final testnet this week. The update introduces PeerDAS, a new data-sampling method expected to make layer-2 transactions dramatically faster and cheaper by expanding blob space in each block. Vitalik Buterin has called PeerDAS “the key to layer-2 scaling,” framing Fusaka as a major step toward Ethereum’s long-term goal of mass, low-cost global adoption. Ethereum’s core developers have officially set a date for the network’s next major update.  The Fusaka upgrade will go live in just over a month’s time, on December 3, the developers agreed during a meeting Thursday.  The date had previously been floated for Fusaka’s implementation, but not formally finalized. On Tuesday, the update cleared its third and final testnet dress rehearsal without a hitch, paving the way for its mainnet activation. “The people I’ve talked to in the community are very excited about it,” Alex Stokes, the Ethereum developer who led Thursday’s meeting, said of Fusaka. “It’s a really big deal.”  The highly anticipated software update seeks to make Ethereum significantly more scalable by optimizing how the network collects and verifies data from layer-2 chains. It introduces several proposals focused on improving efficiency and user experience, building on advances made in earlier upgrades. Ethereum’s 2024 Dencun upgrade introduced “blobs,” a feature that allowed for the temporary storage of layer-2 data on Ethereum transaction blocks. The innovation greatly reduced both gas fees and processing time for layer-2 transactions. Fusaka will expand on the innovation by increasing the blob space available in each Ethereum transaction block—a move that Ethereum’s developers anticipate will make layer-2 transactions even faster and nearly free over time. The expansion is powered by a new data-sampling method, introduced in Fusaka, called PeerDAS. While PeerDAS was originally slated for…
