bitcoin hold several around 7 transaction per second
the ethereum blockchain currently supports roughly 15 transactions per second
nano is better but
compare to
the 45,000 processed by Visa.\/
Transactions are an innate problem of Blockchain. A big downside, so to speak. The more transactions there are, the more time and money is needed for them to be confirmed. And I think your Visa info is wrong. From what I see it's around 1.7k transactions per second, not 45k. But let's return to cryptos. The only thing you can do with blockchain is trying to increase the number of transactions a coin would be able to process in advance. But the main problem with more transactions requiring more time and money will always remain. DAG, on the other hand, is designed in the opposite way, with confirmation stuff being tough at first, but getting better as more transactions occur. I believe this article and an image in it is useful to understand it:
https://steemit.com/cryptocurrency/@steemhoops99/transaction-speed-bitcoin-visa-iota-paypal/how visa can hold 1.7 k per second with all the transcation going inside the usa to you get what you say..
and its depend on the protocol that use to verifiy the tps each protocol/blockchain has different way which show you even know what is fhantom or spectre or ghost protocols and how they differ from bitcoin protocol and where dag protocol enter here and how oother important things try to solve this problem...
dude go back to school you talk non sense from the moment you said visa hold 1.7k per second if yes visa would crash every second from overload transcation...
and about dat i already explained how it work so you sound more stupid then smart and you only copy pasy you really dont know how it work and what weakness it have??
you even dont know what is phantom protocol or spectra and others,,,you just copy past what is dag and in reality you even dont know how it work.
so to see so much people talk so much non sense but on reddit they will debunk you under one second you even will log off it will go viral, because on reddit people there learn rather then feel smart and talk bullshit and copy past something that already explained by me..
