Highlight of the Week

  • The Ethereum Foundation unveiled its new cross-Layer-2 interoperability initiative on 18 Nov 2025 — simplifying how users and applications move assets and data between roll-ups and the main chain.

Eth R&D & Protocol Calls

Layer 1

Research

  • Emergent-consensus without a chain: Explores whether global linear history is necessary, proposing a topology-driven, emergence-based consensus model and examining implications for validator coordination, ordering guarantees, and fault-tolerance boundaries.

Stuff for Developers

  • Foundry released a nightly update with minor fixes including corrected comments for Git functions and optimizations for Anvil's internal data handling.

Security

  • Cloudflare experienced a major outage on November 20 that took down 20% of the web for 3 hours, including crypto exchanges and Twitter. While blockchain networks continued to operate, many front-end interfaces were inaccessible, highlighting the irony of decentralized protocols relying on centralized infrastructure.

Ecosystem

Notable at app layer

  • Stream Finance experienced a catastrophic failure on November 18, with $93 million vanishing and their stablecoin xUSD crashing 77%. The collapse followed October warnings about Stream's 4x leverage and recursive loops, resulting in $285 million in exposure being unwound. While Trevee (a related protocol) recovered through aggressive action, most depositors face near-total losses.

Centralization watch: threatening the value of your ETH

  • 🚨 Lido at 23.94%, still too close to the 33.3% threshold.

  • Client diversity (via clientdiversity.org):

    • Execution layer: Geth ~41% & Nethermind ~38%

    • Consensus layer: Lighthouse ~42.71% & Prysm ~30.91%

    • Any client bug over 33.3% could mean loss of finality.

  • Better geographic diversity is optimal, particularly outside of North America & Europe.

Client Releases

  • Consensus layer:

    • Lighthouse v8.0.1: A hot-fix release correcting several bugs in the v8.0.0 rollout (including removal of checkpoint-server blob downloads pre-Fulu fork, a fix for a custody-context race condition causing panics, and preventing unnecessary pre-fork state advances).

EIPs/Standards

Onchain Stats

  • Fees (via ultrasound.money):

    • Gas: 0.0 to 16.8 gwei, 0.5 gwei average; zero net issuance at 16.2 gwei

    • 18.02 ETH net issuance this week

  • ETHUSD: $2,680 – $3,237, currently $2,760, all-time high $4,946

  • ETHBTC: currently 0.032 (Flippening at ~0.165)
