Demolition of a mystery mystery **
As one of the Bitcoin Core (BTC) node, you have a limited ability to measure the total number of Bitcoin network nodes. The answer is to understand how the network distribution is shared and how data is exchanged between nodes.
Understanding the topology of the network
In a decentralized network, such as Bitcoin, each node acts as a relay station, conveying messages from one peer to another. However, not all nodes are active or connected at the same time. Nodes with no peers or those who have been abandoned for a long time are known as «dead» nodes.
Network traffic and node number
The number of active nodes on the Bitcoin network is difficult to determine directly as it depends on several factors, such as maintaining a node, restarting or simply offline mode. However, we can estimate the total number of nodes by analyzing network traffic models.
According to a 2019 study, which analyzed between 2007 and 2018, about 6 million unique addresses were created. Each address is related to the public key, and each public key corresponds to one Bitcoin address.
By using this information, researchers estimate that the Bitcoin network today has about 12-15 million active nodes. However, these estimates may not be completely accurate, as some nodes may still be active, but are in the rest of a long time.
How to find the number of nodes
Although the exact number of nodes is challenging, we can use different metrics and methods to better understand the network:
- Node density : The density of the knot is the ratio of the total node to the largest possible capacity of the network. A higher node density indicates a more active network.
2
- Information in mining area operators : Some mining pool operators publish information on their website or public forums that may contain information on the total number of addresses, active mining workers and events.
Current Reviews
According to different sources, including the 2020 report of the CoinmarketCap, the estimated number of nodes on the Bitcoin network is approximately:
* 12-15 million : This estimate comes from researchers who used information since 2018.
* 20-30 million : A newer estimate based on network traffic models and mining-based data.
Note that these estimates may vary according to the source, the methodology and the scheduled schedules. However, they give a picture of the relative scale of the Bitcoin network.
conclusion
Although we cannot directly calculate the number of nodes in real time, analysis of network traffic models, node density and mining pool operators provides valuable views on the total Bitcoin network size. One node you may not be able to give an exact answer, but by studying these indicators you can get a deeper understanding of the Bitcoin ecosystem.
