Scientific reproducibility fails when data provenance is opaque. Off-chain databases allow silent edits, versioning errors, and ambiguous timestamps, corrupting the experimental record. This is a core systems failure, not a human one.

Why On-Chain Provenance is Non-Negotiable for Reproducibility
The scientific method is built on verification, yet modern research is plagued by irreproducible results. This analysis argues that immutable, on-chain provenance for data, code, and analytical steps is the only viable foundation for a new era of credible, collaborative science.
introduction
THE PROVENANCE IMPERATIVE
The Reproducibility Crisis is a Data Integrity Crisis
Reproducible science requires immutable, timestamped data lineage, a guarantee only on-chain provenance provides.
On-chain provenance is non-negotiable because it creates an immutable, timestamped ledger for every data point. Protocols like Arxiv's KZG commitments and IPFS content-addressed storage provide the cryptographic primitives, but the chain provides the global ordering and finality.
The counter-intuitive insight is that data integrity precedes analysis. A perfect model trained on corrupt or unverifiable data is scientifically worthless. On-chain provenance shifts the burden of proof from trust to cryptographic verification.
Evidence: The Polygon ID and Verifiable Credentials (W3C) ecosystems demonstrate that selective disclosure of attested data is possible, but only if the root attestation lives on a public, immutable state machine like Ethereum or Celestia.

THE NON-NEGOTIABLE FOUNDATION
Thesis: Immutable Provenance is the First-Principle Solution
On-chain provenance is the only mechanism that guarantees verifiable and tamper-proof reproducibility for digital assets and processes.
Immutable provenance solves trust. It creates a permanent, cryptographically verifiable record of an asset's origin and entire history. This eliminates reliance on fallible intermediaries and opaque databases.
Reproducibility requires a single source of truth. Without a canonical ledger like Ethereum or Solana, verifying the lineage of an NFT or a DeFi transaction becomes a forensic exercise across siloed, mutable systems.
Smart contracts enforce provenance rules. Protocols like OpenSea's Seaport and ERC-721 enforce standard metadata and ownership transfer logic. This programmatic layer makes provenance machine-readable and automatically verifiable.
Counterfeit detection is trivial. A provenance ledger instantly exposes fake assets. The $100M+ in NFT wash trading detected by platforms like CryptoSlam relies on analyzing this immutable transaction graph.

THE FOUNDATION FOR TRUSTLESS REPRODUCIBILITY
The Three Pillars of On-Chain Provenance
Reproducibility is the cornerstone of scientific and financial rigor. In crypto, it's impossible without an immutable, shared ledger of state transitions.
01
The Problem: Off-Chain Black Boxes
Traditional APIs and centralized databases are mutable and opaque. You cannot independently verify the history of an asset or the execution path of a transaction, creating a single point of failure and trust.
- No Audit Trail: Cannot prove a DeFi yield claim or NFT lineage wasn't retroactively altered.
- Fragmented State: Data lives in siloed servers, not a shared, canonical source of truth.

The Solution: Immutable State Logs (EVM, Solana, Cosmos)
Blockchains provide a globally synchronized, append-only ledger. Every state change is a transaction with a cryptographic fingerprint, enabling anyone to replay history from genesis.
- Deterministic Execution: Given the same initial state and transaction list, any node produces identical outcomes.
- Full Auditability: Tools like Etherscan, Dune Analytics, and The Graph parse this public log for forensic analysis.

The Enforcer: Consensus & Cryptographic Proofs
Provenance is worthless if the log can be forked or rewritten. Nakamoto Consensus (Proof-of-Work) and BFT-style consensus (Proof-of-Stake) provide economic finality.
- Economic Security: Altering history requires attacking the chain, costing billions in ETH or SOL.
- Light Client Proofs: Protocols like zkSync and Celestia use validity proofs and data availability sampling to trustlessly verify state without running a full node.

THE NON-NEGOTIABLE LEDGER
How On-Chain Provenance Rebuilds Trust
On-chain provenance provides an immutable, verifiable audit trail for digital assets, making reproducible results a technical guarantee, not a promise.
Reproducibility requires immutability. Off-chain data silos and mutable APIs create a single point of failure for verification. On-chain provenance, anchored in protocols like Arweave for permanent storage or Ethereum for state commitments, ensures the historical record of an asset's origin and journey is cryptographically sealed and publicly accessible.
Trust shifts from institutions to code. Traditional provenance relies on trusted third-party attestations, which are opaque and fallible. On-chain provenance automates verification through smart contracts and zero-knowledge proofs, as seen in Polygon's zkEVM for state integrity, making trust a verifiable computation.
It enables composable truth. A provenance record stored on-chain becomes a public good for developers. Protocols like Aave can verify collateral history, and NFT marketplaces like Blur can authenticate entire creator lineages, without needing to rebuild trust layers for each new application.
Evidence: The Ethereum blockchain processes over 1 million transactions daily, each creating a permanent, timestamped record. This scale of immutable data availability is the foundational layer for reproducible DeFi positions, NFT royalties, and cross-chain asset transfers via LayerZero.

The Problem of Verifiable Off-Chain Compute: Axiom vs. RISC Zero
Smart contracts are limited. These protocols generate cryptographic proofs of off-chain computation, bringing complex logic (AI, gaming, analytics) on-chain with verifiable provenance.
- Axiom: ZK proofs for historical Ethereum state (e.g., prove your NFT ownership history)
- RISC Zero: General-purpose zkVM for provably correct execution of any Rust code
- Unlocks trustless automation and data-rich DeFi primitives

THE VERIFIABLE RECORD
Objection: Isn't This Just Expensive Metadata?
On-chain provenance is a tamper-proof, executable record, not passive data, making it the only reliable foundation for reproducible AI.
Provenance is executable context. Storing a model hash on-chain is just metadata. Full provenance includes the immutable, verifiable lineage of training data, code commits, and hardware signatures, creating a deterministic audit trail.
Reproducibility demands consensus. Off-chain logs are mutable and unverifiable. On-chain state, secured by networks like Ethereum or Solana, provides a single source of truth that all parties can trust without a central authority.
Smart contracts enforce integrity. This record isn't passive. It enables automated verification and royalties via protocols like EZKL for proof verification, turning static data into an active compliance and incentive layer.
Evidence: The cost is negligible versus value. Storing a compressed ZK proof of a model's training run on Arweave or Filecoin costs under $5, creating an immutable certificate more valuable than the model itself.
