it definitely has it flaws, but the layer 2 has done helped the scalability to some extent by offloading the transaction to these layer 2 blockchains which in result after the introduction of blobs to replace calldata proven to help reduce the transaction fee significantly meaning the attempt to scale further the ethereum blockchain is somewhat successful though occasionally when there are sudden flood of transaction such as when there's airdrop claiming event and so on, the fee get back up again. at this point I think the problem in regard of scalability almost solved.
What are your thoughts? Does ETH have a bad network design? If not, why? What do you think would be the best approach for scaling ETH (aside from centralized L2s)? Your input would be greatly appreciated. Thank you.
And that is why the Layer 2 solution was first created on the Ethereum network due to its scalability issue. They have added so many upgrades to the network that I cannot remember but those have not been effective. The transaction fees are still high and that is the reason why the BSC chain became popular in the last bull run and the next in line will be the Solana network as that is what I can forsee. A lot of new crypto projects are now using other blockchains that are cheaper, faster, and can handle congestion or they are using a layer 2 solution.
the perk of being latecomer they can easily find the weak point that they can improve on in releasing the next iteration of the smart contract based blockchain but being the first ever smart contract blockchain as ethereum is that you just don't know what kind of problem gonna be appearing next that could possibly congest the blockchain. so can't really blame ethereum on falling short on certain capability.
at the end of the day ethereum still got that advantage of matured ecosystem overall which many new blockchain can't imitate or come close to.
hopefully next upgrade there will be many surprises that could help significantly in improving ethereum scalability.
