2024-2025: Node Infrastructure Evolution

The blockchain node ecosystem experienced significant maturation from 2024 through 2025, with focus shifting from pure decentralisation metrics to practical operational infrastructure supporting Lightning Network payments, L402 micropayments for AI services, and integrated identity systems.

Bitcoin Node Landscape

The Bitcoin network maintained approximately 15,000 publicly-reachable nodes distributed globally, representing a triumvirate of economic actors: holders/users trading and speculating; miners securing the network through Proof of Work validation; and node operators enforcing consensus rules and trust minimisation. Since IT engineer Stadicus released the RaspiBolt guide in 2017, small-scale Bitcoin and Lightning node operators proliferated—around 30,000 Raspberry Pi Lightning nodes (which are also by definition Bitcoin nodes) ran open-source distributions, democratising network participation.

Lightning Network Infrastructure

Lightning node management software matured substantially, with tools like Torq providing workflow automation for large Lightning Network nodes, enabling institutional-grade operations. L402 emerged as a critical innovation: a Lightning-native reverse proxy standard enabling micropayment-gated API access, particularly relevant for AI services requiring per-query payment without traditional subscription models. This infrastructure positioned Lightning as the native payment rail for machine-to-machine commerce.

Bitcoin-Dollar Interoperability

Stablesats and similar technologies introduced algorithmic dollar-stable value using exclusively Lightning Bitcoin, providing price stability without centralised stablecoin issuers. More significantly, Strike’s opening of public Lightning network access enabled individuals with self-hosted wallets or nodes to pay directly for goods across America, with instant settlement in dollars using Bitcoin at zero cost. This bridged the Lightning network with dollar-denominated metaverse stores, creating unprecedented interoperability between cryptocurrency infrastructure and traditional commerce.

Distributed Identity and Data

Emerging protocols integrated with Bitcoin’s node infrastructure: Nostr provided decentralised identity and messaging layers, whilst SOLID-lite data pods enabled private data storage with cryptographic access control. These systems layered on top of Bitcoin’s settlement layer, creating a full-stack decentralised internet infrastructure where nodes served not just financial settlement but also identity, communication, and data storage—a vision of truly peer-to-peer digital infrastructure. The Cleveland Federal Reserve published analysis confirming Lightning Network’s potential to transform Bitcoin from speculative asset to functional money, validating technical infrastructure developments with academic economic analysis. By late 2025, node operation transitioned from ideological hobby to practical infrastructure requirement for individuals and businesses seeking financial sovereignty and censorship-resistant commerce capabilities.

Institutional Node Infrastructure and the Centralisation Paradox

Whilst retail Bitcoin node operators democratised network participation through Raspberry Pi deployments, the broader multi-chain blockchain ecosystem witnessed dramatic consolidation of node infrastructure into institutional providers servicing hundreds of thousands of developers and applications: Dominant Institutional Providers:

  • Alchemy: Emerged as the preeminent blockchain infrastructure provider with support for Ethereum, Polygon, Solana, Arbitrum, Optimism, and 15+ chains, powering some of the largest DeFi protocols, NFT marketplaces, and Web3 applications. Alchemy’s robust APIs, exceptional developer experience, and enterprise-grade reliability (99.9% uptime SLAs) attracted major projects including OpenSea, Axie Infinity, and numerous institutional financial applications. By 2025, Alchemy served over 500,000 developers, representing an estimated 70-80% of Ethereum dApp traffic routing through Alchemy infrastructure
  • Infura (ConsenSys subsidiary): Operated as the second-largest Ethereum Virtual Machine (EVM)-compatible blockchain infrastructure provider, supporting Ethereum, Polygon, Arbitrum, Optimism, and other EVM chains. With over 400,000 developers registered on the platform by 2025, Infura provided the critical RPC (remote procedure call) infrastructure enabling wallets (MetaMask), block explorers (Etherscan), and dApps to interact with blockchains without operating full nodes. Infura’s integration with MetaMask—the dominant Web3 wallet with 30+ million monthly active users—created single point of failure concerns: when Infura experienced outages (March 2020, November 2020, January 2023), vast swaths of Ethereum’s user-facing applications became temporarily inaccessible
  • Blockdaemon: Focused on institutional-grade blockchain infrastructure and validator-as-a-service, trusted by over 300 financial institutions and managing 100,000+ nodes across 50+ blockchain networks by 2025. Blockdaemon’s enterprise positioning—offering dedicated infrastructure, compliance reporting, and institutional SLAs—attracted banks, asset managers, and hedge funds deploying blockchain strategies. Major clients included Deutsche Bank, BNY Mellon, and Citi, signalling traditional finance’s reliance on third-party node infrastructure rather than self-hosted infrastructure
  • InfStones: Specialised in institutional staking infrastructure managing over $10 billion in staked assets across Ethereum, Solana, Polkadot, Cosmos, and 30+ proof-of-stake networks by 2025. InfStones provided white-label staking services enabling exchanges (Crypto.com, OKX) and custodians to offer staking yields to customers without operating validator infrastructure internally
  • Figment: Advanced staking provider supporting 40+ blockchain networks, managing over $15 billion in staked assets and serving institutional clients including asset managers, hedge funds, and crypto-native companies. Figment’s institutional focus and compliance capabilities (SOC 2 Type II audits, GDPR compliance) positioned it as the preferred provider for regulated entities entering staking markets Centralisation Concerns and Decentralisation Theatre: The consolidation of node infrastructure into handful of institutional providers created fundamental tensions with blockchain’s decentralisation ethos:
  • RPC centralisation: Despite Ethereum’s 400,000+ validator nodes (post-Merge) creating robust consensus decentralisation, the vast majority of users and applications accessed the network through centralised RPC providers (Alchemy, Infura, QuickNode). This created a centralisation paradox: consensus was decentralised, but access was centralised, enabling potential censorship at the infrastructure layer (RPC providers could theoretically filter transactions, censor addresses, or deny service to specific applications)
  • Validator centralisation risks: In proof-of-stake networks, institutional staking providers (Coinbase, Figment, InfStones, Blockdaemon) controlling 30-40% of total staked assets across multiple networks created single-entity risks: if major provider experienced technical failure, compromise, or regulatory pressure (e.g., government order to censor transactions), significant portion of network’s validation capacity could be affected simultaneously
  • Geographic concentration: Major node providers operated data centres predominantly in United States and Europe (AWS, Google Cloud, Microsoft Azure regions), creating geographic centralisation where 50-60% of blockchain validator nodes ran in U.S.-controlled cloud infrastructure by 2025. This exposed networks to jurisdictional risk: U.S. regulatory actions could potentially affect majority of validation infrastructure simultaneously
  • Cloud infrastructure dependency: Estimated 60-70% of Ethereum validators ran on Amazon Web Services (AWS) infrastructure, 15-20% on Google Cloud, and 5-10% on Microsoft Azure, with only approximately 10-15% on dedicated/bare-metal servers. This created catastrophic failure scenarios: AWS outages (December 2021, December 2022) caused widespread disruptions to blockchain networks despite consensus layer remaining operational—users and applications couldn’t access networks due to infrastructure-layer failures Regulatory Compliance and Censorship Risks: The August 2022 Tornado Cash sanctions by U.S. Office of Foreign Assets Control (OFAC) exposed infrastructure-layer censorship vulnerabilities: following sanctions, major RPC providers (Alchemy, Infura, QuickNode) blocked transactions interacting with Tornado Cash smart contracts, demonstrating that centralised infrastructure created de facto censorship capability even on ostensibly censorship-resistant blockchains. By 2024-2025, concern intensified around MEV-Boost relays and block building centralisation: over 90% of Ethereum blocks were built by small number of specialised block builders (Flashbots, BloXroute, Eden Network) rather than validators directly, creating transaction ordering centralisation and potential censorship points. Following Tornado Cash sanctions, some block builders implemented OFAC compliance filtering, excluding sanctioned addresses from blocks—though other builders maintained censorship resistance, creating a two-tier block building market. Self-Hosted Node Renaissance and Solutions: Awareness of infrastructure centralisation risks catalysed self-hosted node movement through 2024-2025:
  • Home staking initiatives: Ethereum Foundation’s promotion of home staking as “decentralisation ideal” encouraged individuals to run validators on consumer hardware (NUC, custom builds, Raspberry Pi 4+ with external SSD). By 2025, an estimated 15-20% of Ethereum validators ran on home hardware vs. cloud/institutional infrastructure, up from approximately 10-12% in 2022
  • Node-in-a-box products: Plug-and-play node solutions (DAppNode, Avado, RaspiBlitz, Umbrel) reduced technical barriers for self-hosting blockchain nodes, enabling non-technical users to operate full nodes and validators with minimal configuration. These products integrated Bitcoin full nodes, Lightning nodes, Ethereum validators, and IPFS nodes into unified interfaces
  • Decentralised RPC alternatives: Protocols like Pocket Network (decentralised RPC marketplace), Ankr (decentralised node infrastructure), and The Graph (decentralised indexing) emerged as alternatives to centralised providers, incentivising distributed node operators through token rewards. By 2025, Pocket Network supported 60+ blockchains with 70,000+ distributed nodes, though still represented <5% of total RPC traffic compared to Alchemy/Infura dominance
  • Client diversity improvements: Ethereum’s push for client diversity (running multiple node implementations—Geth, Nethermind, Besu, Erigon—to reduce single-client bugs affecting network) achieved 45-50% Geth dominance by 2025, down from 70-75% in 2021, reducing single-implementation risks though still below desired <33% per-client threshold Future Trajectory: Decentralisation Resurgence or Permanent Centralisation? By mid-2025, blockchain node infrastructure existed in a bifurcated state: Bitcoin maintained relatively robust node decentralisation (15,000+ public nodes, 30,000+ Lightning nodes operated by individuals), whilst multi-chain ecosystems (Ethereum, Polygon, Solana, Cosmos) exhibited consensus decentralisation but infrastructure centralisation, with majority of user/developer access mediated by handful of institutional providers. Potential trajectories included:
  • Permanent infrastructure centralisation: Developer convenience and institutional reliability requirements entrench Alchemy/Infura/Blockdaemon oligopoly, with decentralised consensus layers masked by centralised access layers—“decentralisation theatre” where networks are theoretically censorship-resistant but practically vulnerable to infrastructure-layer control
  • Decentralised infrastructure maturation: Protocols like Pocket Network, Ankr, and client-side light clients (EIP-4844 enabling trustless light clients) mature to provide comparable performance/reliability to centralised providers, gradually redistributing infrastructure market share to distributed operators and reducing single-entity risks
  • Regulatory forcing function: Government intervention targeting major providers (subpoenas for transaction data, mandatory censorship, service bans) creates regulatory necessity for decentralised alternatives, accelerating adoption of self-hosted and distributed infrastructure solutions The 2024-2025 period crystallised blockchain node infrastructure’s fundamental tension: technical decentralisation without infrastructure decentralisation created systems that were theoretically censorship-resistant yet practically vulnerable to centralised control points—a tension likely to define security and resilience debates for the remainder of the decade.

Current Landscape (2026)

  • Ethereum’s Fusaka (Fulu-Osaka) upgrade activated on mainnet on 3 December 2025 (slot 13,164,544), introducing PeerDAS data-availability sampling so each full node custodies only a subset (as little as 1/8th, non-validating nodes ~1/32nd) of blob data rather than all of it, with staged Blob-Parameter-Only (BPO) forks raising the blob target to 10 (Dec 2025) and 14 (Jan 2026).
  • Partial history expiry (EIP-4444) shipped across all execution clients from July 2025, letting node operators drop pre-Merge block data to reclaim 300-500 GB and fit a node on a 2 TB disk; ERA files (ERA-E execution, ERA-C consensus) standardise how pruned history is archived, with retention shifting to archive nodes, the Portal Network and specialised indexers.
  • Stateless clients moved from theory towards production: Paradigm’s Ress (Reth Stateless), announced March 2025, ran fully-validating stakers on the Holesky testnet with only ~14 GB disk (a ~70x reduction) and sub-second block validation, natively supported via the ress RLPx subprotocol in Reth from v1.3.1 without any hard fork.
  • The Rust-based Reth execution client has become the high-performance default: Base deprecated Geth entirely in its favour, Optimism scheduled the end of op-geth support by May 2026, and networks such as 0G migrated validators from Geth to Reth (March 2026), citing ~24% lower block-execution latency (Geth 25.3ms to Reth 19.1ms p50) and ~40% faster sync on BNB Chain.
  • Verkle Trees are slated as the headline of Ethereum’s Hegotá fork (targeted H2 2026, following Glamsterdam in H1), swapping the Merkle Patricia Trie for polynomial vector commitments that shrink block witnesses from megabytes to ~1-2 KB and cut node storage by roughly 90%, with Geth, Nethermind, Besu, Erigon and Reth already running testnet migration tools.
  • Node operation is increasingly outsourced to managed and decentralised RPC infrastructure: QuickNode, Alchemy, Helius, Chainstack, Ankr and dRPC dominate provisioning, while decentralised fabrics such as Pocket Network, Lava Network and dRPC provide censorship-resistant fallback; on Solana, Jump Crypto’s Firedancer (tile-based C/C++ validient client) and Agave set a high hardware floor of 512 GB+ RAM and 24+ cores for production validators.
  • Open challenges as of 2026 centre on capping state growth rather than merely slowing it (state expiry must accompany Verkle Trees), completing multi-client Verkle migration and security audits, reconciling ever-higher throughput (bigger blobs, gas-limit increases) with home-staker hardware limits, and preserving decentralisation as heavy RPC and archive workloads consolidate onto a handful of specialised operators.
