Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network.
Reachable nodes ranked according to their Peer Index (PIX) as of . PIX values are calculated only for activated nodes.
| NODE | RANK | ADDRESS | PIX | VI | SI | HI | AI | PI | DLI DUI |
WLI WUI |
MLI MUI |
NSI | NI | BI |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| No 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) x 10.0
VI = Protocol version index
VI = 1 / r
r = rank of node's protocol version
Consensus protocol version is ranked 1 followed by the next most common protocol version
SI = Services index
SI = 1 / r
r = rank of node's services
Consensus 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 = ln((1 / n) x N) / ln(N)
N = number of reachable nodes
n = number of nodes from N with the same ASN
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 = 1.0 for ≈ 99th percentile
0.9 for ≈ 90th percentile
0.8 for ≈ 80th percentile
0.7 for ≈ 70th percentile
0.6 for ≈ 60th percentile
0.5 for ≈ 50th percentile
0.4 for ≈ 40th percentile
0.3 for ≈ 30th percentile
0.2 for ≈ 20th percentile
0.1 for ≈ 10th percentile
0.0 for < 10th percentile
NI = Nodes index
NI = (p ∩ N) / N
p = peers returned in addr responses
N = reachable nodes
NI >= 6σ is capped at 99th percentile
BI = Block index
BI = 1.0 if valid block is returned in response to getdata request, 0.0 if otherwise
Be 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.
