RPC endpoints are centralized bottlenecks. Every dApp query and transaction relies on a single, trusted server operated by providers like Infura or Alchemy, creating a systemic vulnerability.
Why RPC Endpoints Are a Centralized Chokepoint
An analysis of how reliance on centralized RPC providers like Infura and Alchemy undermines core Web3 principles, creating systemic risks of censorship, frontrunning, and data manipulation that threaten user sovereignty.
Introduction
RPC endpoints are the centralized chokepoint that undermines the decentralized promise of blockchains.
This architecture inverts decentralization. While the blockchain ledger is distributed, the primary access layer is not, making applications dependent on the uptime and integrity of a few corporate entities.
Evidence: The 2022 Infura outage crippled MetaMask and major exchanges, demonstrating how a single provider failure can halt the entire Ethereum ecosystem.
The Core Argument
RPC endpoints are a single point of failure that undermines the decentralization of every major blockchain.
RPCs are centralized infrastructure. Every dApp query and transaction passes through a centralized gateway controlled by a handful of providers like Infura, Alchemy, and QuickNode. This creates a single point of failure for the entire application stack.
Decentralization ends at the RPC. A protocol can have thousands of nodes, but if all clients connect to the same three RPC providers, the network's censorship resistance is illusory. This is the same architectural flaw that plagues centralized bridges like Stargate and LayerZero.
Providers control state access. RPC operators can filter, delay, or censor transactions without the underlying blockchain's consensus. This creates a permissioned layer that contradicts the trustless ethos of protocols like Ethereum and Solana.
Evidence: During Infura's 2022 outage, MetaMask and major dApps went offline, proving the entire ecosystem's dependence on this centralized chokepoint.
The Centralization Landscape
Blockchain's foundational infrastructure is dominated by a handful of centralized providers, creating systemic risk and rent-seeking.
The Single Point of Failure
RPC endpoints are the gateway to every blockchain. Centralized providers like Infura and Alchemy act as critical chokepoints for ~80% of Ethereum traffic. This creates systemic censorship and downtime risk, as seen when Infura's outage bricked MetaMask for millions.
- Censorship Vector: A single provider can block transactions.
- Data Integrity Risk: Users must trust the provider's chain state.
The Extractive Middleman
Centralized RPC providers insert themselves as rent-seeking intermediaries. They capture value by monetizing API calls and MEV (Maximal Extractable Value) opportunities, siphoning billions in potential user value annually. This model is antithetical to decentralized finance's ethos.
- Hidden Costs: 'Free' tiers monetize via data and order flow.
- MEV Capture: Centralized sequencing enables front-running.
The Compliance Trap
Centralized infrastructure is subject to jurisdictional regulation. Providers like Infura have already complied with OFAC sanctions, blocking access to Tornado Cash-related smart contracts. This turns infrastructure into a tool for regulatory overreach, compromising chain neutrality.
- Protocol-Level Censorship: Compliance filters at the RPC layer.
- Fragmented Access: Geoblocking creates multiple internets.
The Performance Illusion
While centralized providers offer low-latency performance (~100ms p95), it's achieved through massive, centralized server farms. This creates a false trade-off between decentralization and speed, stifling innovation for truly distributed, high-performance networks like POKT Network or Lava Network.
- Artificial Monopoly: Scale begets scale, locking in dominance.
- Innovation Stagnation: No incentive to improve decentralized stacks.

Anatomy of a Chokepoint
RPC endpoints are a centralized chokepoint that undermines blockchain's decentralized promise by controlling all data access.
RPC is the only door. Every dApp query and wallet transaction must pass through a single, centralized Remote Procedure Call (RPC) endpoint. This endpoint is the sole gateway for reading blockchain state and broadcasting transactions.
Infrastructure centralization is systemic. Despite decentralized node networks, application access is centralized. Over 80% of Ethereum traffic flows through centralized providers like Alchemy, Infura, and QuickNode, creating systemic risk.
The chokepoint enables censorship. A provider can selectively censor or front-run transactions by filtering or reordering requests. This defeats the core guarantees of permissionless access and fair ordering.
Evidence: The 2022 Infura outage took down MetaMask, dApps, and CEX deposits for hours. This demonstrated that centralized RPCs are a systemic risk equivalent to a Layer 1 halt.
The Steelman: Why Centralization Happened
RPC centralization is a rational, emergent property of protocol economics and infrastructure scaling, not a design flaw.
Protocols optimize for throughput, not decentralization. Ethereum's core design pushes state execution to clients, creating a massive data processing burden. Running a full node requires significant capital and operational overhead, which most dApp developers cannot justify.
Infrastructure becomes a commodity. Services like Alchemy and Infura emerged by offering a superior product: global low-latency endpoints, advanced APIs, and predictable pricing. They achieved economies of scale that individual teams cannot replicate, creating a natural monopoly.
The economic flywheel is vicious. As developers flock to the most reliable RPC, the provider's revenue and network effects grow. This funds better infrastructure, widening the gap with self-hosted solutions. The cost of failure for a dApp (downtime) far exceeds the RPC bill.
Evidence: Over 50% of Ethereum's RPC traffic routes through Alchemy and Infura. Layer 2s like Arbitrum and Optimism often launch with a single, centralized sequencer and RPC provider because speed-to-market trumps decentralization.
The Sovereign Stack: Emerging Alternatives
RPC endpoints are the silent centralizers of Web3, creating systemic risk and rent extraction for developers and users.
The Single Point of Failure
Centralized RPC providers like Infura and Alchemy control access for >50% of Ethereum traffic. This creates systemic censorship and downtime risk, as seen during OFAC-compliance events.\n- Censorship Vector: Providers can block transactions to sanctioned addresses.\n- Data Monopoly: Centralized logging creates a honeypot for user and MEV data.
Decentralized RPC Networks (e.g., Pocket, Ankr)
These protocols distribute requests across a permissionless network of node operators, eliminating single-provider risk.\n- Censorship Resistance: No single entity can filter transactions.\n- Economic Efficiency: ~30-50% cost reduction via competitive, token-incentivized markets.\n- Redundancy: Built-in failover across 1000s of global nodes.
The Self-Hosted Validator Stack
The ultimate sovereignty: running your own execution and consensus clients (Geth/Lighthouse) with a local RPC. This is the gold standard for protocols like Lido and Rocket Pool.\n- Total Control: Zero reliance on third-party APIs or data integrity.\n- MEV Capture: Direct access to the mempool for proprietary strategy execution.\n- High Barrier: Requires significant DevOps overhead and ~$1M+ in staked ETH for consensus.
Light Clients & Portal Networks
Projects like Ethereum's Portal Network and Helios enable stateless verification of chain data without syncing a full node. This is the future of truly decentralized frontends and wallets.\n- Trustless Verification: Cryptographically verify state proofs directly from the p2p network.\n- Mobile-Native: Enables secure, lightweight access on resource-constrained devices.\n- Killer App: The foundational layer for The Graph-like querying without central servers.
TL;DR for CTOs & Architects
Your decentralized application's most critical dependency is a centralized, single-point-of-failure service.
The Single Point of Failure
Traditional RPC providers like Infura and Alchemy are centralized chokepoints. Their outages have historically taken down major dApps, wallets, and protocols, proving the fallacy of 'decentralized' infrastructure.
- ~70% of Ethereum traffic flows through a handful of providers.
- A single provider's downtime can halt $10B+ in DeFi TVL.
- Creates systemic risk for the entire application layer.
The Censorship & MEV Vector
Centralized RPC endpoints are a powerful tool for transaction censorship and MEV extraction. Providers can front-run, censor, or reorder your users' transactions, directly undermining core blockchain guarantees.
- Providers can blacklist addresses (e.g., Tornado Cash) at the RPC level.
- Transaction ordering is a lucrative MEV opportunity controlled by the endpoint.
- Breaches the principle of permissionless access.
The Performance & Cost Trap
You're paying for shared, rate-limited infrastructure with unpredictable performance. During network congestion, your users face degraded latency and failed transactions, directly impacting UX and protocol revenue.
- P95 latency spikes to ~5s+ during high gas periods.
- Global Anycast routing often fails to optimize for geographic proximity.
- Opaque, usage-based pricing creates unpredictable operational costs.
The Solution: Decentralized RPC Networks
Networks like POKT Network, Lava Network, and Ankr's decentralized RPC distribute requests across a global, permissionless node set. This eliminates single points of failure and aligns incentives with the network's health.
- Fault tolerance via multi-provider redundancy.
- Censorship resistance through node diversity.
- Competitive pricing via a marketplace model.
The Solution: Self-Hosted & Specialized RPCs
For maximum performance and control, run your own nodes or use specialized providers like Chainbound or BlastAPI. This is non-negotiable for high-frequency trading, gaming, or any latency-sensitive application.
- Sub-100ms latency for custom geo-optimized setups.
- Full control over transaction ordering and privacy.
- Predictable, fixed costs independent of public mempool chaos.
The Solution: Intent-Based & Bundler RPCs
Next-gen architectures like UniswapX, CowSwap, and ERC-4337 bundlers abstract the RPC layer entirely. Users submit intents (desired outcomes), and a decentralized solver network competes to fulfill them, bypassing traditional RPC limitations.
- Removes gas estimation failures and front-running.
- Better execution via MEV capture and refunds.
- Native cross-chain capabilities (e.g., Across, LayerZero).
