Fun fact: Ethereum's Nakamoto coefficient (min number of validator nodes/operators needed to disrupt the network) is actually double Solana’s right now (details below). ETH = 41 SOL = 20 LIDO ≠ 1 entity (common misunderstanding that leads to incorrect takes) Lido is a network consisting of 500+ independent operators. I could be disingenuous and claim that means the coefficient is 500+ but I won't. Sol Foundation originally counted Lido as 1 operator but was also willing to revise their reports. The reality is that ~96% of current stETH is from the curated module, an independent group of 36 operators. So the correct calculation is: ETH: 36 (Lido curated module set) + 1 (Coinbase) +1 (Kraken) +1 (Binance) +1 (Kiln) +1 (Etherfi has multiple operators but afaik list isn't public so counting as one entity) = Top 41 validator operators for 50%+ of staked ETH to disrupt the network. Solana: Top 20 validators by stake needed to halt/censor the network.

Note that for Ethereum the 50%+ threshold was used because that's when serious damage requiring social recovery can be done. 33%+ can only temporarily prevent finalization, which would be annoying but not actually halt or stop the network from functioning. Txs wouldn't be guaranteed to be irreversible during that time, but the inactivity leak penalty would kick in causing the 33% rogue stake to bleed until finalization resumes. Final thoughts: Nakamoto coefficient isn’t a complete indicator since it’s only 1 attack vector. For the sake of Ethereum's decentralization I do hope Lido agrees to self limit, expand the curated operator set, and significantly increase the % cap of the community staking module!
