Ethereum’s development team has officially set December 3, 2025, as the launch date for the Fusaka upgrade, following the successful completion of its third and last testnet stage, according to
a Decrypt report
. This upgrade will bring PeerDAS, an innovative data sampling solution that aims to cut layer-2 transaction expenses and boost scalability by increasing blob storage capacity by more than 400%, as detailed in
a Coinotag article
. This achievement is being described as a crucial advancement in Ethereum’s journey to serve as a global settlement platform for decentralized apps and rollups, with Decrypt calling it a significant leap forward.
Fusaka builds upon the Dencun upgrade from 2024, which brought temporary blob storage to help reduce layer-2 gas fees. With PeerDAS (Peer Data Availability Sampling), validators can check data from layer-2 networks without needing to download the full datasets, greatly lowering bandwidth needs, according to
a Coinotag report
.
Ethereum
co-founder Vitalik Buterin has described PeerDAS as “the cornerstone of layer-2 scaling,” highlighting its ability to make transactions nearly free and support up to 2.4 million settlements per day, a point also mentioned by Coinotag.
Testnet rollouts for the upgrade on Holesky, Sepolia, and Hoodi finished smoothly, with Hoodi’s activation on October 28 confirming mainnet readiness, as outlined in
a Coinotag update
. Developers postponed PeerDAS from the February 2025 Pectra upgrade to allow for more thorough testing, reflecting the network’s careful approach to stability, according to Coinotag. If Fusaka succeeds, Ethereum could compete with high-speed blockchains like
Solana
, which currently finalizes blocks in less than a second, compared to Ethereum’s average of 12 seconds, as reported by
another Coinotag report
.
Reactions from the market have been mixed. Although Ethereum’s native coin, ETH, recently saw $555 million withdrawn from ETFs over two weeks, according to
a TradingView report
, institutional interest remains robust. For instance, SharpLink Gaming recently acquired $78.3 million in ETH, raising its treasury to over 859,000 ETH valued at $3.62 billion, as noted in
a Crypto.News report
. At the same time, ETH’s price has bounced back to $4,229, a 7.5% increase in 24 hours, as bulls aim for a breakout above $4,250 toward October highs, according to
a Crypto.News piece
.
Prediction markets show optimism, with 61% of Myriad users expecting ETH to rise above $4,500 rather than drop below $3,100, as reported by Decrypt. Still, ETH’s 2.3% weekly dip to $3,760 points to ongoing volatility, also covered by Decrypt. After Fusaka, Ethereum’s roadmap features the 2026 Glamsterdam upgrade, which seeks to further cut block times and introduce enshrined proposer-builder separation, according to earlier Coinotag coverage.
