Nakamoto Coefficient Meaning

The Nakamoto Coefficient is a quantitative measure used to assess the decentralization of a blockchain network. Named after Bitcoin's creator, Satoshi Nakamoto, it represents the minimum number of independent entities (nodes, validators, or miners) that would need to collude to compromise the network-usually defined as controlling 51% of the resources (hash rate or stake).

A high Nakamoto Coefficient indicates a decentralized and robust network. For example, if it takes 1,000 distinct miners to reach 51% of the hash rate, the coefficient is 1,000.

A low coefficient indicates centralization. If just 3 mining pools or 4 validators control 51% of the network, the coefficient is 3 or 4, meaning the network is vulnerable to censorship or collusion by a very small group of people.

This metric is crucial because many blockchains claim to be "Decentralized" while actually being controlled by a handful of entities. Tracking the Nakamoto Coefficient over time allows researchers to see if a blockchain is becoming more democratic or if power is consolidating into the hands of large conglomerates like centralized exchanges or liquid staking providers.
