Bitcoin Network Crawler

Q: How many Bitcoin nodes exist worldwide?

Our crawler discovers thousands of reachable Bitcoin nodes. The actual number is higher as many nodes operate behind firewalls without accepting incoming connections.

Q: What hardware do I need for a Bitcoin node?

Minimum requirements: 1 TB SSD, 8 GB RAM, and a stable internet connection. A Raspberry Pi 5 or any low-power mini-PC works well. Initial sync takes 1-3 days.

Global overview of all reachable Bitcoin nodes

Our Bitcoin network crawler continuously scans the peer-to-peer network to discover active full nodes. Each node validates transactions and blocks independently, contributing to Bitcoin's decentralization and security.

What is a Bitcoin Node?

Full Node vs. Light Node

A Bitcoin full node stores the complete blockchain (over 500 GB) and validates every transaction independently. Unlike light nodes (SPV), full nodes don't trust third parties – they verify everything themselves. This makes them essential for Bitcoin's trustless architecture.

Why Run a Bitcoin Node?

Running your own node gives you financial sovereignty – you verify your own transactions without trusting exchanges or third-party services. Node operators also strengthen the network's decentralization and help new nodes synchronize faster.

Network Types: IPv4, IPv6 & Tor

Bitcoin nodes communicate via different network layers. IPv4 nodes are the most common, while IPv6 adoption grows steadily. Tor (.onion) nodes provide enhanced privacy by hiding the operator's IP address, though with slightly higher latency.

Frequently Asked Questions

How many Bitcoin nodes exist worldwide?

Currently, our crawler has discovered 26164 nodes in total, of which 14741 were reachable in the last 24 hours. The actual number of nodes is likely higher, as many operate behind firewalls or NAT without accepting incoming connections.

Which Bitcoin Core version should I run?

Always use the latest stable Bitcoin Core release from bitcoincore.org. Newer versions include security patches, performance improvements, and protocol upgrades. Check our version statistics above to see the most popular versions across the network.

How often is this data updated?

Our Bitcoin network crawler runs continuously, checking node reachability every few minutes. The statistics on this page refresh every 5 minutes. Click on any node to see detailed latency and uptime history.

What hardware do I need for a Bitcoin node?

Minimum requirements: 1 TB SSD (the blockchain grows ~50-80 GB/year), 8 GB RAM, and a stable internet connection. A Raspberry Pi 5 or any low-power mini-PC works well. Initial sync takes 1-3 days depending on your hardware and bandwidth.
