It's getting annoying to see people talking about a project is the next Ethereum killer, for how long are we going to keep this up?
so far in which part you talking about ETH killer ? transaction speed and fee or anything else ? if you talking about it i am believe solana bsc and matic have it. daily transaction amount also very high and it enough to said as eth killer. but we must accept another point that how this killer overcome network while traffic full.
To Solana or other ecosystems like Near, Avalanche… has fast transaction speed and cheap gas fees, these ecosystems have given up some decentralization to get the above. This goes against decentralized blockchain technology, this will make Solana very susceptible to sudden shutdown affecting the user experience.
even network traffic on solana could shutown due its uses growth that significantly. maybe hathor could be best layer1 blockchain which is combine POW and DAG which is could handle unlimited transaction.
