Decentralization is the core ethos of the blockchain, and people can sometimes be maximalist in defining what is decentralized or not. They believe a blockchain is either decentralized or it isn’t, but this removes a lot of nuance. It is more prudent to treat decentralization as a spectrum, and the position of a particular network on the spectrum can be determined by many factors, ranging from technical architecture to the distribution of wealth and power
1. Node Count and Geographic Distribution in Blockchain
The most obvious factor in measuring decentralization is the node count; a network with 200,000 nodes is way more robust than one with just 200. But number isn’t the only thing to be considered here, it is also better if the nodes are geographically and technologically diverse, that is, spread them across the world so a blackout in Texas does not take the whole network offline, and spread it across various infrastructures so an AWS data center issue does not destroy the network.
2. The Nakamoto Coefficient
The Nakamoto Coefficient was introduced by Balaji Srinivasan, and it represents the least number of entities that can compromise one part of the network. Basically, if 4 mining pools hold more than 51% of a network hash power, then 4 is the Nakamoto Coefficient is 4. Networks with a greater coefficient are more decentralized by this metric.
3. Barriers to Entry (Hardware Requirements)
This is basically measuring decentralization by the cost of participation. If it requires a $20,000 server and a high-speed industrial internet connection to participate in the network, this significantly limitsits and centralizes the participant pool. Basically, the easier it is to participate, the more decentralized the network is.
4. Governance and Development
This measures how decentralized the decision-making of a network is. If one person or entity can decide when a protocol is upgraded, it is less decentralized than a network that requires 5 entities.
5. Token Distribution
To some extent, we can also measure how decentralized a network is by how many people hold the token and the wealth gap among investors. For instance, five venture capital firms held 70% of the tokens, the consensus mechanism is dominated by this 5 and makes it more centralized.
