Actually the scalability problem of ETH was already solved by ETH's cofounder himself in the name of
Dr. Gavin Wood but unfortunately, he already left ETH and made eth 2.0 with its name
POLKADOT.
Scalability problems has already been fixed on Near Protocol with a 100k TPS, Polkadot is great no doubt about that but honestly speaking near Protocol has a more user friendly blockchain that is ready for the masses, starting from low gas fees, fast TPS and UI & UX friendly, sharding will soon go live on Near blockchain and its gonna be fucking epic.
LOL! Near protocol isn't really that close enough or near to POLKADOT's power when its 100 parachains go live. Polkadot can do 1 million TPS and that's coming right from Dr. Gavin Wood's mouth. Polkadot is actually the blockchain against maximalism.
