Centralized repositories are attack vectors. They consolidate trust in a single operator, making them prime targets for exploits like the $600M Poly Network hack, which stemmed from a compromised private key.
Why Centralized Repositories Are a Single Point of Failure
A technical analysis of how centralized academic databases like PubMed Central create systemic risk through censorship, link rot, and access control. We explore how decentralized storage networks (IPFS, Filecoin, Arweave) provide a resilient, permanent foundation for scientific knowledge.
Introduction
Centralized data repositories create systemic risk by concentrating trust, control, and failure modes.
Censorship and data manipulation are inevitable. A single entity, like a cloud provider or a centralized indexer, can unilaterally alter or withhold data, undermining protocol neutrality and user sovereignty.
Infrastructure failure cascades. An outage at a service like Infura or Alchemy halts all dependent dApps, demonstrating how centralized dependencies create systemic fragility across the entire Ethereum ecosystem.
Executive Summary
Centralized data repositories create systemic risk by concentrating control, trust, and failure modes in single entities.
The Censorship Vector
A single admin can blacklist addresses or freeze assets, undermining permissionless guarantees. This is not hypothetical—major providers like Infura have complied with OFAC sanctions, breaking core Ethereum principles.
- Single Admin Key controls access for millions of users.
- Protocol-Level Neutrality is outsourced to a corporate entity.
- Creates regulatory honeypots for global adversaries.
The Liveness Bomb
When a centralized RPC or indexer fails, entire application ecosystems go dark. The AWS us-east-1 outage of 2021 took down dApps controlling ~$10B+ TVL because they shared a single infrastructure dependency.
- Cascading Failure across unrelated protocols.
- Zero Redundancy at the service layer.
- ~500ms of downtime can trigger liquidations and arbitrage failures.
The Data Integrity Problem
Users and smart contracts must trust the repository's output is correct. A malicious or compromised provider like a centralized oracle (Chainlink node operator) or bridge custodian can feed invalid state data, leading to stolen funds. The Wormhole $325M hack stemmed from a single validator key compromise.
- Truth is not cryptographically verified at the edge.
- Enables sophisticated MEV extraction and fraud.
- Breaks the trust-minimized security model.
The Economic Capture
Centralized repositories create rent-seeking intermediaries that extract value from the network. Services like Alchemy and centralized sequencers (Optimism, Arbitrum pre-decentralization) capture >90% of transaction fee revenue, creating misaligned incentives and stifling protocol-owned sustainability.
- Value Leakage from the core protocol and its users.
- Monopoly Pricing Power over essential services.
- Inhibits Credible Neutrality and long-term alignment.
The Centralized Repository is an Architectural Antipattern
Centralized data repositories create systemic risk by concentrating trust and attack surface in a single entity.
Centralized repositories are single points of failure. This design pattern reintroduces the exact trust assumptions that decentralized systems aim to eliminate. A single compromised admin key or a legal takedown order can censor or alter the entire dataset, as seen in the OpenSea delisting incident.
The attack surface is concentrated, not distributed. A centralized API or database server presents a monolithic target for DDoS attacks and exploits. This violates the core security principle of minimizing blast radius, a principle that Bitcoin's node network and Ethereum's client diversity enforce through decentralization.
Data availability becomes a permissioned service. Users and applications must trust the repository operator for liveness and correctness. This creates a permissioned layer that contradicts the permissionless composability that drives innovation in ecosystems like Solana and Cosmos.
Evidence: The 2022 Infura outage, a centralized RPC provider, rendered MetaMask wallets and major dApps unusable across Ethereum, Polygon, and Arbitrum, demonstrating the systemic fragility this pattern introduces.

How Decentralized Storage Networks (DSNs) Re-Architect Resilience
Centralized data repositories create systemic risk by concentrating control, cost, and censorship power.
Centralized control creates systemic risk. A single entity, like AWS S3 or Google Cloud, governs access, pricing, and data integrity. This centralization is a single point of failure for availability and a single point of control for censorship.
Decentralized Storage Networks (DSNs) distribute these points. Protocols like Filecoin and Arweave fragment data across a global network of independent storage providers. This architecture eliminates centralized chokepoints for takedowns or outages.
The cost model inverts. Centralized providers extract rent via locked-in APIs and egress fees. DSNs like Filecoin create competitive, open markets for storage, where price is set by supply and demand, not a corporate rate card.
Evidence: The permanence guarantee. Arweave's endowment model and cryptographic proof-of-access structure ensure 200-year data persistence, a service no centralized provider offers or can credibly promise without counterparty risk.
DeSci Protocol Stack: Building on Resilient Foundations
Centralized data silos and publishing platforms create systemic risk for scientific progress, enabling censorship, data loss, and gatekeeping.
The Problem: The Paywall & Access Crisis
Publishers like Elsevier and Springer Nature control access to ~50% of all scientific papers. This creates a $10B+ annual toll on institutions, stifling global research and innovation.
- Gatekeeps Knowledge: Publicly funded research locked behind private paywalls.
- Creates Information Asymmetry: Favors well-funded Western institutions over the Global South.
- Slows Progress: Access delays and costs hinder interdisciplinary and replication studies.
The Problem: Centralized Data Repositories
Platforms like NCBI or Figshare act as trusted, centralized custodians. A takedown request, server failure, or policy change can erase foundational datasets.
- Single Point of Failure: One legal or technical event can make critical data vanish.
- Mutable History: Central admins can alter or retract data post-publication.
- Vendor Lock-in: Data formats and APIs are controlled by the platform, hindering portability.
The Solution: Immutable, Permissionless Ledgers
Protocols like Arweave for permanent storage and IPFS for decentralized content addressing create a canonical, unchangeable record of science.
- Guaranteed Persistence: Pay once, store forever models eliminate link rot.
- Censorship-Resistant: No single entity can alter or remove published work.
- Provenance & Integrity: Timestamped hashes provide an immutable chain of custody for data.
The Solution: Tokenized Incentives & Governance
Networks like Ocean Protocol for data monetization and Gitcoin for funding shift control from corporations to stakeholder-aligned communities.
- Aligns Incentives: Contributors, reviewers, and curators are rewarded directly via tokens.
- Decentralized Curation: Token-weighted governance decides on funding, not editorial boards.
- Composable Funding: Enables novel mechanisms like Quadratic Funding for public goods science.
The Problem: Siloed Computational Analysis
Tools like MATLAB or proprietary bioinformatics suites trap methodologies in walled gardens. Reproducibility fails when software licenses expire or environments change.
- Non-Verifiable Results: Black-box algorithms prevent true peer review.
- Environment Drift: "It worked on my machine" kills replicability over time.
- High Cost Barrier: Proprietary software licenses exclude independent researchers.
The Solution: Verifiable Compute & Open Tooling
Frameworks like Bacalhau for decentralized compute and Ethereum for verifiable execution turn methodologies into auditable, open-source protocols.
- Deterministic Outputs: Same input + code guarantees the same result, anywhere.
- Trustless Verification: Anyone can cryptographically verify that a computation was executed correctly.
- Composable Pipelines: Open tooling allows methods to be chained and built upon freely.
The Centralized Rebuttal (And Why It's Wrong)
Centralized data repositories are not just inefficient; they are a systemic risk that undermines the core value proposition of blockchain.
Centralized repositories create systemic risk. A single compromised API key or corrupted database invalidates the entire data layer, making every dependent dApp and smart contract unreliable.
This architecture reintroduces trusted intermediaries. Projects like The Graph and POKT Network exist specifically to dismantle this model by decentralizing data indexing and RPC access.
The failure mode is catastrophic, not gradual. A centralized indexer outage halts all queries instantly, unlike a decentralized network where individual node failures are survivable.
Evidence: The 2022 Infura outage froze MetaMask and crippled major exchanges, demonstrating how centralized infrastructure creates correlated failure across the ecosystem.
TL;DR for Builders and Funders
Centralized repositories for critical infrastructure like package managers and RPCs create systemic risk for the entire Web3 stack.
The npm/github.com Attack Surface
A single compromised package or hijacked maintainer account can poison the entire dependency tree. This is not hypothetical; see the event-stream and ua-parser-js incidents.\n- Supply Chain Poisoning: Malicious code injected into a popular library propagates to thousands of downstream projects.\n- Developer Trust Exploitation: Attackers target maintainers or use stolen credentials to publish malicious updates.
RPC Provider Centralization
Over 70% of Ethereum traffic flows through a handful of centralized RPC providers like Infura and Alchemy. Their failure equals network failure for dependent dApps.\n- Censorship Vector: Providers can theoretically censor or reorder transactions.\n- Data Integrity Risk: A malicious or compromised provider can return incorrect chain data, breaking application logic.
The Solution: Decentralized Protocols
Replace centralized chokepoints with permissionless, incentivized networks. This is the core thesis behind protocols like POKT Network (RPC), Socket (liquidity), and ENS (naming).\n- Fault Tolerance: No single entity can take the system down.\n- Censorship Resistance: Transactions and data retrieval are distributed across many independent nodes.
Build With Redundancy & Verification
Architect applications to assume infrastructure will fail. Use multiple RPC providers, on-chain light clients for verification (like Succinct, Lagrange), and immutable IPFS/Arweave for frontends.\n- Fallback Logic: Automatically switch providers on failure or suspicious data.\n- Local Verification: Cryptographically verify critical data (e.g., Merkle proofs) client-side.
