You're very much wrong, Grins innovation is not removing the hard block size limit, that many other coins don't have.

There's nothing stopping Bitcoin scaling to 100MB blocks with today's hardware, the problem is long term blockchain growth, and validation times, that sort of thing.

Grins innovation is the entire blockchain is can be shrunk using algebraic reduction, unlike other cryptocurrencies that scale linearly with total transaction amount, Grin only saves unspent transactions and a small proof of the total history of the coin since it's mining date.

This means that a 100GB ledger could be reduced down to 100s of MB of its size, and be a just as provably secure as the original unreduced ledger.
