Node map

Explore approximate geography from our crawler's vantage point.

Countries

Compare reachable counts and observed node records by country.

Software versions

Compare self-reported software among reachable nodes.

Network trends

Understand what a snapshot can and cannot tell us over time.

Top Bitcoin node countries

Countries ranked by reachable node records. Observed counts include other statuses; shares use all node records, including unknown geography.

Network trends

A current snapshot cannot establish network growth. Atlas does not yet publish a historical aggregate series. Compare today's dimensions and read how changes in sampling affect interpretation.

How to interpret network changes

Run your own Bitcoin node

Running a node is optional. Start with the machine you have, understand the storage and bandwidth tradeoffs, and decide whether public inbound reachability fits your needs.

  1. Choose hardware
  2. Install Bitcoin Core
  3. Sync and validate
  4. Configure reachability
  5. Check your node

Practical node guides

What is a Bitcoin node?

Understand validation, mining, wallets and pruned nodes.

Why is my node not reachable?

Work through listening, router, firewall and ISP checks.

Node privacy basics

Understand what public reachability can reveal and what it cannot.

Browse the complete Bitcoin node guide library.

For developers

Build research tools and dashboards with the free public API for reasonable use. Cache responses and keep node checks deliberate.

Public data, with clear limits

An observed view from our crawler's vantage point, not a complete census. Reachable means a successful Bitcoin P2P handshake. IP geolocation is approximate. How Atlas measures the network.
