Did Eth have the kind of network problems at the beginning of development that happened to Solana and Harmony?
Not really lol.
A lot of the software right now is being pushed out on a skeleton basis so that the foundation treasury can be enriched.
And it's not just $ONE, Solana has had extensive network shutdowns among other major coins as well. People are seriously overinvested in vaporware these days that come nowhere near their theoretical TPS capacity/stability.
