If this is possible, then such coin will have to be a centralized coin, because from all indications, a coin with a decentralized platform cannot have an infinite scalability.
Come to think of it, most coins that are highly scalable are centralized, let alone infinite scalability.
Well, it might be a breakthrough, because there has not been any of such nature.
Yes. I'm aware of that. Most highly scalable cryptocurrencies have a high level of centralization within them. Even if they're disguised as decentralized coins to the public (like Ripple/XRP does), they're theoretically centralized by design. With all the available technologies today, it's possible to achieve infinite scalability. Nano and IOTA can do this, despite being more centralized than leading cryptocurrencies.
However, one cryptocurrency which seems to retain decentralization while providing infinite scalability is Pascalcoin. This one has been under the radar though, from many investors and crypto traders alike. By using the "Safe Box" concept, Pascalcoin is able to achieve limitless scalability by simply purging most blockchain data while retaining the most important things (which are the balances of each users' accounts). It's an interesting and unique approach, but not proven yet to be exactly as claimed.
Nonetheless, it would be amazing to achieve infinite scalability without sacrificing decentralization. Of course, it's nearly impossible to achieve this, as one needs to have a balance between convenience and security/decentralization. Sometimes, there are highly scalable cryptocurrencies that are convenient, but they lack decentralization. The same thing happens vice versa where there are cryptocurrencies like Bitcoin, which are highly secure and decentralized, but are extremely inefficient. Just my thoughts
