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 Thu Jun 1 08:15:51 2023 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 otherwiseBe part of the Bitcoin network by running a Bitcoin full node, e.g. Bitcoin Core.
Use this tool to check if your Bitcoin client is currently accepting incoming connections from other nodes. Port must be between 1024 and 65535.
