According to @jih2nn, moving Ethereum slot time from 12s to 6s is the hardest part because client internals assume 12s timers and prototypes were only run with a single client pair on a local devnet, leaving multi-client interoperability risks unknown, source: @jih2nn on X, Dec 2, 2025. According to @jih2nn, the 6s testing complexity has not been reviewed by the testing team, indicating unassessed QA scope, source: @jih2nn on X, Dec 2, 2025. According to @jih2nn, the proposed 6s design sits on top of ePBS and there is no finalized Glamsterdam-based spec while the Fusaka-based spec PR remains unfinished, and further analysis on ePBS is needed, source: @jih2nn on X, Dec 2, 2025. According to @jih2nn, 6s does not demonstrate good technical readiness and Heka and Bogotá should prioritize more mature research and development features amid a push for faster fork cadence, source: @jih2nn on X, Dec 2, 2025. According to @jih2nn, traders should watch ePBS spec progress and multi-client interop testing as primary signals for any 6s-related catalysts for ETH rather than assuming near-term latency or throughput gains, source: @jih2nn on X, Dec 2, 2025.

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.
