Why Shared Security Dilutes Accountability

Superchain security is a shared liability model, not a guarantee. A malicious sequencer can censor or reorder transactions for profit, but the economic penalty is diluted across all rollups.\n- No Sovereign Slashing: Individual L2s cannot slash the shared sequencer's stake for chain-specific violations.\n- Collective Punishment: A major exploit on one chain triggers a slash that punishes all, creating misaligned incentives.

Disputes must escalate to the L1 (e.g., Ethereum) for final resolution, introducing critical latency and cost. This turns security into a slow, expensive arbitration process.\n- ~7 Day Windows: Fraud proof challenge periods create a week-long vulnerability window for stolen funds.\n- L1 Gas Auction: Honest actors must outbid attackers in a costly gas war to prove fraud, a prohibitive cost for smaller chains.

A failure in the shared security layer (e.g., sequencer bug, validator collusion) compromises every connected chain simultaneously. This creates systemic risk akin to a cloud provider outage.\n- Correlated Failure: Unlike isolated app-chains, a superchain exploit is a cross-chain contagion event.\n- TVL Concentration Risk: A single security provider backing $10B+ in aggregate TVL becomes a high-value target for novel cryptoeconomic attacks.

Projects like Celestia, EigenLayer, and Babylon enable rollups to source security without ceding sovereignty. This allows for customized slashing conditions and direct accountability.\n- Modular Security Stack: Decouple data availability, sequencing, and settlement, avoiding single-provider lock-in.\n- Restaking Economics: Protocols can attract security via EigenLayer AVSs or similar, creating a competitive market for cryptoeconomic safety.

Consumer chains like Stride and Neutron lease security from the Cosmos Hub's Interchain Security (ICS). This creates a principal-agent problem: the Hub's validators are economically accountable for the security of chains they don't operate, while the consumer chain developers face no direct slashing risk for their own bugs.

• Misaligned Incentives: Hub validators prioritize ATOM staking rewards over the health of obscure consumer chains.
• Risk Contagion: A critical bug in a small consumer chain could trigger mass slashing of the Hub's $2B+ validator set, punishing uninvolved delegators.

EigenLayer allows ETH stakers to restake their stake to secure additional services (AVSs). This fragments the security budget of Ethereum, creating a moral hazard where AVS operators chase yield with minimal skin in the game.

• Security Dilution: A single validator's 32 ETH now backs multiple systems, multiplying its failure domains.
• Opaque Risk: Stakers delegate to operators based on APY, not the technical risk of the AVSs, leading to a race to the bottom on security standards.

Parachains win a slot auction to share the Relay Chain's security for up to two years. This creates a temporary, transactional security relationship where long-term accountability is absent.

• Crowded Security: The Relay Chain's validators must secure 50+ parachains, making deep specialization and oversight impossible.
• Post-Slot Cliff: After a lease expires, a parachain faces a security black hole, often leading to a rushed renewal or a risky migration to a less secure solo chain.

Lido controls ~30% of staked ETH via its decentralized validator set. While not a traditional shared security model, it exemplifies accountability diffusion at governance layer. The Lido DAO, a diffuse group of LDO token holders, makes critical technical decisions (e.g., oracle upgrades, node operator sets) for the underlying ETH stakers.

• Principal-Agent Problem: ETH stakers (principals) have no say; LDO voters (agents) bear no direct slashing risk.
• Systemic Risk: A governance exploit or collusion could compromise the security of $30B+ in staked ETH.

When security is a pooled resource, individual chain operators have no skin in the game for failures elsewhere. This dilutes accountability and creates a moral hazard.

• Free Rider Problem: A poorly secured appchain jeopardizes the entire pool's $10B+ TVL.
• Risk Obfuscation: Investors can't assess the specific risk profile of a single chain, only the aggregate.

Enforcing slashing for subjective failures (e.g., censorship) across hundreds of Actively Validated Services (AVS) is politically and technically fraught.

• Coordination Failure: A 51% attack on one AVS requires slashing the majority of the network's stake—a non-starter.
• Inaction as Default: The path of least resistance is to slash no one, making the security guarantee purely economic, not cryptographic.

The alternative is vertically integrated security where the chain, sequencer, and prover are a unified, accountable entity. See Monad, Fuel, Celestia rollups.

• Clear Accountability: A single team is responsible for liveness and correctness.
• Optimized Performance: Tight integration enables ~500ms block times and minimal overhead.
• Investor Clarity: Due diligence targets a specific stack, not an opaque pool of capital.

Modular chains (using shared DA/security) optimize for capital efficiency and launch speed but inherit systemic risk. Monolithic chains (like Solana, Monad) optimize for performance and sovereign accountability.

• Builder Choice: Need to ship fast? Use a rollup stack. Building a performance-centric L1? Go monolithic.
• Investor Lens: Modular investments are bets on ecosystem accretion; monolithic bets are on execution and throughput.

Shared security often necessitates trusted bridging between chains, creating a single point of failure. Contrast with LayerZero's decentralized oracle/relayer model or Chainlink CCIP.

• Bridge Risk: A compromise in the shared security layer can bridge-attack all dependent chains.
• Solution: Prefer omnichain or intent-based interoperability (e.g., Across, Socket) that doesn't rely on a universal set of validators.

The real investment opportunity isn't in the shared pool itself, but in SaaS for sovereign chains. This includes dedicated ZK prover networks, high-performance sequencers, and RaaS providers like Caldera, Conduit.

• Recurring Revenue Model: Capture fees from chains that value performance over shared risk.
• Market Shift: As shared security risks materialize, demand for premium, dedicated security will spike.
