According to @VitalikButerin, "You can just build on L1," posted on X on Nov 30, 2025, emphasizing Ethereum’s base layer as a place to deploy applications, source: @VitalikButerin on X, Nov 30, 2025. On Ethereum mainnet, smart contracts execute directly on the base layer under Ethereum’s consensus security, source: Ethereum.org documentation on smart contracts and security. On-chain demand increases gas fees and burns ETH through EIP-1559’s base fee mechanism, directly linking mainnet activity to ETH supply dynamics, source: Ethereum.org EIP-1559 explainer and gas fees guide. Layer 2 rollups post transaction data to L1 and rely on Ethereum for settlement and security, clarifying how L1 usage and rollup activity are structurally connected, source: Ethereum.org Layer 2 documentation. For trading, the concrete on-chain metrics tied to potential L1 usage shifts are gas price, base fee burn rate, and the net ETH supply trend, source: Ethereum.org EIP-1559 explainer and gas fees guide.

According to the source, a social media post claims an Ethereum upgrade named Fusaka will go live on December 3, 2025 and target up to 10x higher data capacity via PeerDAS to benefit Layer 2 rollups, source: X post dated Sep 19, 2025. PeerDAS is formally specified in EIP-7594 as peer-to-peer data availability sampling designed to expand blob data bandwidth for rollups, which directly lowers rollup data costs versus calldata, source: EIP-7594. EIP-4844 (Dencun) previously introduced blob data that reduced rollup data costs and enabled lower L2 fees, providing a baseline for how increased data bandwidth can affect L2 economics, source: Ethereum Foundation blog on Dencun and EIP-4844. Before positioning, traders should verify any upgrade name and timeline on official venues where confirmations are typically published, including the Ethereum Foundation blog and Ethereum AllCoreDevs call notes, source: Ethereum Foundation blog; Ethereum AllCoreDevs notes. If PeerDAS is scheduled, trading-relevant monitors include L2 blob utilization, blob fee dynamics, and rollup throughput, as these metrics influence L2 activity and ETH usage for data publication on L1, source: EIP-7594; EIP-4844.

According to @jih2nn, an Ethereum prototype successfully reduces slot time from 12 seconds to 6 seconds and remained stable across several epochs in testing, signaling fast finality progress beyond the research phase, source: https://twitter.com/jih2nn/status/1964624878126190919; https://notes.ethereum.org/@miloss/Prototyping_EIP-7782. The code and configuration for the EIP-7782 prototyping effort were published for review, providing implementation details that developers and traders can track for readiness signals, source: https://notes.ethereum.org/@miloss/Prototyping_EIP-7782; https://twitter.com/jih2nn/status/1964624878126190919. If Ethereum retains 32 slots per epoch as defined in the consensus specs, cutting slot time to 6 seconds would reduce epoch duration from about 6.4 minutes to about 3.2 minutes, accelerating finality and on-chain settlement speed relevant for trade confirmation, source: https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/; https://twitter.com/jih2nn/status/1964624878126190919. Faster L1 finality can compress DEX arbitrage and MEV windows and shorten Layer 2 rollup bridge confirmation times that depend on L1 finality, a dynamic traders should monitor across ETH pairs and major ERC-20s, source: https://ethereum.org/en/developers/docs/scaling/rollups/; https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/. No mainnet activation timeline or gas-per-slot policy changes are stated in the shared materials, so price and volatility impact should be tied to upcoming devnet/testnet milestones and client release notes rather than immediate assumptions, source: https://twitter.com/jih2nn/status/1964624878126190919; https://notes.ethereum.org/@miloss/Prototyping_EIP-7782.

According to @KookCapitalLLC, Caldera is a modular blockchain platform enabling developers to create custom Layer 2 (L2) rollups with Ethereum-level security, optimized for fast and low-cost decentralized applications (dApps). Early users can potentially profit by 'farming' Caldera, which involves engaging with the ecosystem, testing applications, and interacting with new protocols to qualify for future rewards or airdrops (source: @KookCapitalLLC, Twitter, May 6, 2025). This presents a unique opportunity for crypto traders to capitalize on emerging trends in scalable blockchain infrastructure, particularly as Caldera positions itself as a goldmine for early adopters within the growing L2 rollup sector.
