About ChainQuery.com

ChainQuery.com is a research surface for Bitcoin. We publish the largest set of address attributions available online that is built entirely from primary attestations rather than clustering inference, alongside live on-chain signals, historical reports, RPC documentation, and curated reference content.

Operating since 2015, run by Treib Holdings. We query our own Bitcoin Core node and surface the results directly, so every page on this site is grounded in the chain rather than in a third-party index.

Address attribution, without clustering

Most public "exchange wallet" databases derive attributions from common-input or change-output heuristics. We do not. Every address in our corpus carries a citation back to a primary source: a self-disclosed proof-of-reserves attestation, a published government sanctions list, an academic dataset, a curated community blocklist, or an on-chain coinbase signature. When multiple independent sources name the same address, we surface the agreement count rather than collapsing into one assertion.

What's here

  • Address lookup: enter any Bitcoin address; we return every attribution we hold for it plus live chain stats (balance, transaction count, received / spent).
  • Source catalog: every attribution source, with its methodology, update cadence, and confidence rationale documented on a dedicated page.
  • Curated lists: Bitcoin rich list, mining-pool reward addresses, sanctioned wallets, proof-of-reserves disclosures, provably-lost coins, exchange addresses.
  • Stories: walk through pivotal Bitcoin moments with live RPC calls embedded inline.
  • RPC playground: every Bitcoin Core RPC documented and classified by safety tier; read-only RPCs executable directly against our node.
  • Historical reports: mempool, fee, network, mining, chain, and UTXO timeseries snapshotted on a fixed cadence.
  • Sanctions API: free, unauthenticated, CORS-open lookup against the aggregated sanctions feeds.
  • Signals API: bearer-token feed of mempool fee signals.

Operations

We own and operate our full node directly rather than relying on a third-party API. There is no clustering layer in the pipeline, no commercial indexer between us and the chain, and no rate-limited free tier games. Bitcoin Core 28.0.0 is the primary source.
