Why Zero-Knowledge Proofs Are Reshaping Investment Theses

Rollups post compressed transaction data on-chain, but this data is still public and expensive. Full nodes must re-execute everything to verify state, limiting scalability and privacy.

• Public Data: All transaction details are exposed on L1.
• High Cost: ~80% of rollup costs are for L1 data posting.
• Verifier Complexity: Nodes require significant compute.

Replace data posting with a cryptographic proof of correct execution. Validiums use proofs with off-chain data, while zkRollups can optionally post data. This decouples security from full data availability.

• Scalability: ~10,000 TPS achievable with off-chain data.
• Cost: ~90% reduction vs. optimistic rollups for data-heavy apps.
• Instant Finality: State is finalized as soon as the proof is verified on L1.

ZKPs enable private smart contracts where logic is verifiable but inputs remain hidden. This unlocks institutional DeFi and compliant on-chain identity, moving beyond simple payment privacy.

• Private State: Shielded pools and confidential DeFi (e.g., zk.money).
• Regulatory Path: Selective disclosure via proofs for compliance.
• New Markets: Enables $1T+ traditional finance asset migration.

Proving systems like Plonky2 and Nova enable recursive proofs, where one proof verifies others. This allows for proof aggregation layers (e.g., Polygon zkEVM, zkSync) and decentralized prover networks.

• Cost Amortization: Batch thousands of transactions into one final proof.
• Decentralization: Moves proving away from centralized sequencers.
• Interoperability: Enables lightweight ZK verification across chains.

Fully Ethereum-equivalent zkEVMs (e.g., Scroll, Taiko) mean all existing dApps can migrate without modification. This positions Ethereum L1 as a ZK-verification hub, a universal settlement layer for all chains.

• Developer Inertia: Zero code changes required for migration.
• Settlement Security: Inherits Ethereum's $100B+ security budget.
• Modular Future: L1 becomes a proof verifier, not an executor.

The investment thesis pivots from Total Value Locked (TVL) as a primary metric to Transactions Per Second and Transactions Per Cent. ZK tech enables hyper-scalable, low-cost blockspace, valuing infrastructure that commoditizes proof generation.

• New Metrics: Cost-per-proof and prover decentralization.
• Vertical Integration: Winners will control the full stack (zkVM, prover network, sequencer).
• Moats: Cryptographic innovation and hardware acceleration (GPU/ASIC).

Rollups are constrained by their parent chain's data capacity and cost. Ethereum's ~80 KB/s blob throughput creates a hard ceiling for all L2s, capping scalability and creating fee volatility.

• Celestia and EigenDA emerged as modular solutions, but introduce new trust assumptions.
• The ZK Stack enables sovereign rollups that can post proofs anywhere, decoupling execution from a single DA layer.

A framework for launching interconnected ZK-powered L2/L3s with shared security and native interoperability. It turns scalability into a composable resource.

• Shared Prover Network: Hyperchains can leverage a decentralized prover marketplace, reducing individual chain overhead.
• Native Bridge: Trust-minimized communication between chains via ZK proofs, unlike optimistic bridge delay models.
• Enables app-specific chains without the security trade-offs of a standalone alt-L1.

Multi-chain ecosystems suffer from isolated liquidity pools and delayed, trust-based bridging. Users and protocols cannot natively act on a unified global state.

• LayerZero and Axelar use oracles and multisigs, creating new attack vectors.
• Chainlink CCIP introduces a trade-off between decentralization and latency.

Projects like Polyhedra Network and Succinct Labs are building light clients verified by ZK proofs. This allows one chain to cryptographically verify the header/state of another in minutes, not days.

• Enables trust-minimized bridging and cross-chain messaging.
• Paves the way for omnichain applications where logic executes based on proven state from any connected chain, a concept foundational to Chainlink's Cross-Chain Interoperability Protocol (CCIP) vision.

ZK proof generation is computationally intensive, creating risks of prover centralization and high operational costs that get passed to users. This is the single biggest barrier to ZK-Rollup adoption.

• zkEVM provers can require specialized hardware (GPU/ASIC) and gigabytes of RAM.
• High fixed costs disadvantage small chains and applications.

Techniques like Plonky2 (used by Polygon zkEVM) and Boojum (zkSync) use recursive proofs to batch thousands of transactions into a single proof submitted on-chain.

• Nova and SuperNova (from Espresso Systems) enable incremental verification, drastically reducing marginal cost.
• This creates economies of scale and paves the way for decentralized prover networks like RiscZero's Bonsai and =nil; Foundation's Proof Market, commoditizing proof generation.

Rollups post all transaction data on-chain, creating a $1M+ daily cost for L2s and limiting throughput. The solution is a paradigm shift from data availability to proof availability.

• Validity Proofs: ZK-Rollups (zkSync, StarkNet) only need to post a tiny proof, slashing L1 settlement costs by ~90%.
• Modular DA: Projects like Celestia and EigenDA enable rollups to post data off-chain, secured by ZK fraud proofs or cryptographic commitments.

Smart contracts are isolated and cannot efficiently verify complex computations (like ML models). ZK coprocessors enable trustless off-chain execution with on-chain verification.

• Unlocks New Apps: On-chain gaming, verifiable AI, and complex DeFi strategies become feasible.
• Capital Efficiency: Protocols like Aave can perform risk calculations on historical data without expensive on-chain storage, enabling more aggressive capital deployment.

Total transparency limits institutional adoption and user sovereignty. ZKPs enable confidential transactions and selective disclosure.

• Institutional Gateways: Funds can prove compliance (e.g., sanctions screening) without exposing entire transaction graphs.
• Composable Privacy: Private DeFi pools and shielded voting unlock new financial products impossible on transparent chains like Ethereum mainnet.

Generating a ZK proof for every single transaction is slow and expensive. Recursive proofs (proofs of proofs) batch verification, creating a layered efficiency flywheel.

• Aggregators: Projects like Espresso Systems and Nebra act as proof hubs, reducing finality time from minutes to ~seconds.
• Hardware Acceleration: ASICs/GPUs from Cysic and Ulvetanna drive down proof generation costs, making ZK-VMs the default rollup engine.

Trusted multisigs and validator sets are the single point of failure for bridges, responsible for ~$2.5B+ in hacks. ZK light clients enable trust-minimized cross-chain communication.

• IBC on Ethereum: Projects like Succinct use ZKPs to verify Tendermint consensus, bringing IBC to Ethereum.
• Universal Connectivity: Any chain can verify the state of any other chain with a cryptographic proof, not a trusted committee, unlocking secure omnichain apps.

ZK technology is complex and resource-intensive, creating a risk of prover centralization—the antithesis of decentralization. The winning stacks will balance performance with credible neutrality.

• Open Source Provers: Projects must avoid black-box provers to prevent capture (see Mina Protocol's decentralized prover network).
• Hardware Diversity: Proof systems must be ASIC-resistant or foster a competitive hardware market to avoid a single entity controlling settlement.
