Metcalfe's Law has been successfully used to value a variety of network effect technologies and businesses, including Facebook and Tencent. Applying Metcalfe's Law to Bitcoin, using Daily Active Addresses (DAA) as the n value, yields interesting results. Historically, Bitcoin has tracked the Metcalfe Law Fair Price reasonably well The situation was changed in late 2013, when Metcalfe himself used Facebook's data over the past 10 years to show a good fit for Metcalfe's law. In this paper, we expand Metcalfe's results by utilizing the actual data of Tencent (China's largest social network company) and Facebook (the world's largest social network company). Our results show that: 1) of the four laws of network effect, Metcalfe's law by far fits the actual data the best; 2) both Tencent and Facebook data fit Metcalfe's law.
Then in 2015, Zhang, Liu and Xu extend Metcalfe's results by utilizing the actual data of Tencent (China's largest social network company) and Facebook. Their work show that: Metcalfe's law is not only valid for Facebook which in a developed country serving worldwide users, but also valid for Tencent which in a developing country mostly serving Chinese users Correlation Heatmap on Raw Data. Correlation Heatmap on Differenced Data. The main reason I ask is because the two studies I know of that attempt to validate Metcalfe's Law with respect to Facebook and Tencent do not convert non-stationary time series data (e.g., Facebook revenue) into a stationary one before doing a least squares fit
Metcalfe's Law is related to the fact that the number of unique possible connections in a network of n nodes can be expressed mathematically as the triangular number: n(n-1)/2, which is asymptotically proportional to n^2. The law has often been illustrated using the example of fax machines: a single fax machine is useless, but the value of every fax machine increases with the total number of. ., 2015), China's largest social network. It is possible that the relationship between the value of a network and the size of its nodes may depend on the type of network, and networks that can grow freely and organically with little barrier or costs to join the network could follow Metcalfe's relationship. Tencent and Facebook Data Validate Metcalfe's Law. Journal of Computer Science and Technology. 30. 246-251. 10.1007/s11390-015-1518-1. Journal of Computer Science and Technology. 30 Zhang et al. find that Metcalfe's law fits the data best and that the fit is even better for Tencent than for Facebook. Van Hove (2016a), in turn, points out that the value of a social network may also be driven by increases in the variety and quality of the services offered; he therefore explicitly controls for such changes. Van Hove finds that Metcalfe's law now outperforms the other laws even more clearly

Metcalfe's Law has been successfully used to value a variety of network effect technologies and businesses, including Facebook and Tencent. Applying Metcalfe's Law to Bitcoin, using Daily Active Addresses (DAA) as the n value, yields interesting results. Historically, Bitcoin has tracked the Metcalfe Law Fair Price reasonably well. A number of studies have been performed over recent years which validate this and have used various derivations of Metcalfe's Law. Note: this indicator Melde dich bei Facebook an, um dich mit deinen Freunden, deiner Familie und Personen, die du kennst, zu verbinden und Inhalte zu teilen This makes the data vulnerable to hackers who could get all the content by attacking only those one or two servers. In contrast, blockchain technology makes decentralized data storage possible by spreading information across a large network of nodes, so it isn't possible to steal it by attacking only one or two servers. One would have to hack an entire network of nodes. The impracticality of this makes blockchain data storage much more secure than current options Search the world's information, including webpages, images, videos and more.
