Fun fact: Ethereum has the highest economic security in terms of staked value, AND the most validator nodes AND the most home stakers* out of all top smart contract chains. 

Ethereum: 8,200+
Solana: 1,144
Sui: 114
Cardano: 2,990
BSC: 45
Tron: 27

Note: Home stakers are defined here as validator nodes being hosted on a residential connection, instead of a datacenter/cloud provider. I'm not referring to independent node operators (non-institutions/companies), which exist on other chains as well (albeit in small numbers). 

Excluding Ethereum, it appears the validator set of every top smart contract chain is basically just a bunch of crypto companies (CEXs, VCs, staking providers) running nodes in data centers/cloud.

For any serious institution looking to leverage blockchain technology that prioritizes security and decentralization, then Ethereum is the only logical choice.
