The Nakamoto Coefficient is a measure of the smallest number of independent entities that can act collectively to shut down a blockchain. On a typical Proof-of-Stake network the Nakamoto Coefficient is defined by the number of node operators that, together, control more than one third (33.33%) of all stake on the network. Polkadot’s NC is 113, while Solana’s is 18. Essentially DOT is 6X stronger than Solana!
