According to the source, Ethereum core developers have reportedly set a December window for a 'Fusaka' upgrade, but there is no official confirmation on the Ethereum Foundation blog or official communication channels as of today, so the claim remains unverified (source: https://blog.ethereum.org). Traders should wait for verification via AllCoreDevs call notes or an EF announcement, since mainnet upgrade dates are typically published after testnet forks are scheduled and executed (source: https://github.com/ethereum/pm). Historical practice shows confirmed timelines such as Dencun were communicated via EF posts and coordinated across testnets before mainnet activation, creating tradable calendar catalysts once official, not before (source: https://blog.ethereum.org and https://notes.ethereum.org/@timbeiko). Until an official post or client release candidates cite a finalized block or epoch for mainnet, prioritize monitoring EF blog updates, AllCoreDevs notes, and client repos for testnet fork schedules and RC tags as timing signals (source: https://blog.ethereum.org, https://github.com/ethereum/pm, and https://github.com/ethereum/consensus-specs).

According to Vitalik Buterin, there is a plan to implement Fusaka on Layer 1 with PeerDAS, targeting a 48/72 blob limit. This development is crucial for traders as it may enhance scalability and efficiency in blockchain transactions. The goal is to initiate a Fusaka testnet with these parameters immediately after the Pectra system goes live, which could significantly impact transaction throughput and trading activities on the blockchain.

According to Vitalik Buterin, Fusaka's integration on Layer 1 with PeerDAS and a 48/72 blob target/limit is planned for 2025, with the aim to establish a testnet post-Pectra's launch, suggesting potential scalability improvements and new opportunities for traders.
