bitnodesBitnodes estimates the relative size of the Bitcoin peer-to-peer network by finding all of its reachable nodes.
Reachable Bitcoin nodes ranked according to their Peer Index (PIX) as of Fri Jul 18 20:05:11 2025 EDT. PIX values are calculated only for activated IPv4/IPv6 nodes.

PIX value is calculated every 24 hours for each activated node based on its properties and network metrics. The value ranges between 0.0 and 10.0 with 10.0 being the most desirable for the Bitcoin network. The formula used to calculate PIX value is described below.
PIX = ((VI + SI + HI + AI + PI + DLI + DUI + WLI + WUI + MLI + MUI + NSI + NI + BI) / 14.0) * 10.0 rs = Rank score rs = log(max(1.0, rn)) rn = normalized reverse rank = ((rv - 1.0) / (rmax - 1.0)) * 10.0 rv = reverse rank = rmax - (r - rmin) r = rank (see details in the particular index below) cs = Count score cs = 1 - (log(c) / log(n)) n = number of reachable nodes c = subset of n (see details in the particular index below) VI = Protocol version index VI = rs rs = rank score r = rank of node's protocol version Most common protocol version is ranked 1 followed by the next most common protocol version SI = Services index SI = √(rs) rs = rank score r = rank of node's services Most common services is ranked 1 followed by the next most common services SI is set to 0.0 for node without NODE_NETWORK HI = Height index HI = h / H h = node's latest height H = consensus height AI = ASN index AI = (cs + (rs * 2.0)) / 3.0 cs = count score rs = rank score c = number of nodes from n with the same ASN r = CAIDA's AS rank PI = Port index PI = 1.0 for 8333 (default port), 0.0 for other DLI = Average daily latency index DLI = 1.0 for <= 300 ms 0.9 for <= 400 ms 0.8 for <= 500 ms 0.7 for <= 600 ms 0.6 for <= 700 ms 0.5 for <= 800 ms 0.4 for <= 900 ms 0.3 for <= 1000 ms 0.2 for <= 1100 ms 0.1 for <= 1200 ms 0.0 for > 1200 ms DUI = Daily uptime index DUI = t / T t = number of daily ticks with latency > 0 T = number of daily ticks Tick with latency <= 0 indicates that node is unreachable WLI = Average weekly latency index WLI = 1.0 for <= 300 ms 0.9 for <= 400 ms 0.8 for <= 500 ms 0.7 for <= 600 ms 0.6 for <= 700 ms 0.5 for <= 800 ms 0.4 for <= 900 ms 0.3 for <= 1000 ms 0.2 for <= 1100 ms 0.1 for <= 1200 ms 0.0 for > 1200 ms WUI = Weekly uptime index WUI = t / T t = number of weekly ticks with latency > 0 T = number of weekly ticks Tick with latency <= 0 indicates that node is unreachable MLI = Average monthly latency index MLI = 1.0 for <= 300 ms 0.9 for <= 400 ms 0.8 for <= 500 ms 0.7 for <= 600 ms 0.6 for <= 700 ms 0.5 for <= 800 ms 0.4 for <= 900 ms 0.3 for <= 1000 ms 0.2 for <= 1100 ms 0.1 for <= 1200 ms 0.0 for > 1200 ms MUI = Monthly uptime index MUI = t / T t = number of monthly ticks with latency > 0 T = number of monthly ticks Tick with latency <= 0 indicates that node is unreachable NSI = Network speed index NSI = √(log(Pi / 10.0)) Pi = node's speed percentile (to the nearest percentile between 10th and 99th) NI = Nodes index NI = √(rs) rs = rank score r = rank of i i = p ∩ n p = peers returned in addr responses n = number of reachable nodes Largest i (99th percentile) is ranked 1 followed by the next largest i BI = Block index BI = 1.0 if valid block is returned in response to getdata request, 0.0 if otherwise
