THORChain hits a Nakamoto Coefficient of 29.
The Nakamoto coefficient measures decentralization and represents the minimum number of nodes required to disrupt the blockchain's network. A high Nakamoto coefficient means that a blockchain is more decentralized.
'The Nakamoto score takes into consideration how many subsystems(mining, clients, developers, exchanges, nodes, owners) a blockchain has, and how many entities you would have to compromise before gaining control of each subsystem. Basically, a Nakamoto score describes the minimum amount of effort it would take to disrupt any given blockchain. A high coefficient means that a blockchain is harder to disrupt, because it’s more decentralized' - learn.bybit
Table above shows the NC for PoS networks. THORChain has a NC of 29, third to Solana which has a NC of 32.
THORChain recently sharded its Asgard vaults bringing nodes to over 100+.
Conceivably, around 250+ nodes is possible and with better subsystems' distribution, a higher Nakamoto Score should be achievable.
