Blockchain Node and RPC Infrastructure
Node infrastructure market (public rpc registers; operators ranked). The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- DefiLlama Chainlist extraRpcs.js (github.com/DefiLlama/chainlist constants/extraRpcs.js) machine-readable, 2,759 rpc rows on 494 host domains, 127 privacy statements; 13 provider links (11 providers); self-filed by PR, maintainer-reviewed
- ethereum-lists/chains (chainid.network/chains.json) machine-readable, 2,818 chains, 4,190 rpc rows on 1,786 host domains; no operator name; 9 links
- cosmos/chain-registry (*/chain.json apis.rpc provider) machine-readable, 263 chains, 1,574 rpc rows on 443 host domains; 2 links (ankr, pocket-network); most operators are validators not in the catalog
- ethereum/execution-apis JSON-RPC spec + hive rpc-compat not machine-readable: conformance runs against execution CLIENTS (geth, nethermind...), no provider conformance list exists (2026-10-19)
- Solana RPC providers not machine-readable: no public provider register; solana.com lists vendors as prose only (2026-10-19)
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-18 from the 18 providers in this market we could resolve in the catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.
| Tags | Blockchain 94%, Web3 78%, Ethereum 61%, RPC 44%, Real-Time 33%, Solana 33%, Validator 28% |
|---|---|
| Tag groups | Blockchain 100%, gRPC 44%, Staking 39%, Real-Time 33%, Solana 33%, JSON-RPC 28%, MCP 22% |
| Industries | Blockchain, Crypto & Web3 100% |
share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py
Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.
