Briefings

This briefing explains how stacking Fast Confirmation Rule (FCR) and Ethereum Economic Zone (EEZ) infrastructure can reduce cross-layer payment waits from minutes to seconds. The evidence describes a hypothetical scenario where a shop accepts ETH on a rollup, receives USDC via a bridge, and settles instantly. Key facts include FCR reducing the 'being believed' wait to ~13 seconds and EEZ removing the 'getting there' bridge wait. The source notes that while the demo used a stand-in signer, the full implementation remains audited and unaudited. The central finding is that only the 'both together' quadrant achieves true card speed, whereas current checkout models remain bridge-bound.

Key points

• FCR (Fast Confirmation Rule) was merged into Ethereum's consensus specs on 2026-04-16, allowing validators to mark a block safe after ~13 seconds of attestations instead of waiting for full finality.
• EEZ (Ethereum Economic Zone) removes the bridge wait by having rollup and base-layer actions land as a single block, eliminating the need for a trusted intermediate crossing.

Context and limitations

The evidence describes a hypothetical scenario and a single demo using a stand-in signer. The implementation of EEZ is still unaudited, and the source explicitly states that the full implementation remains audited and unaudited.
