Recently, I have been paying attention to the $XPL and Plasma scaling solutions, and I find the approach quite interesting. Essentially, it is an architecture with a mainnet hub + multiple sidechains running in parallel — the mainnet focuses on being the "brain" to maintain security and stability, while the sidechains handle a large volume of transactions, with speeds that are orders of magnitude faster.

This division of labor has a clear advantage: the mainnet doesn't have to sacrifice decentralization for throughput, and the sidechains can use relatively lightweight consensus mechanisms to accelerate transactions. For users, the previous issues of queuing and skyrocketing Gas fees have been significantly alleviated.

In my opinion, this type of scaling solution changes the user experience of blockchain from a certain perspective. Previously, it might have taken minutes or even longer to confirm a transaction, but now transactions are almost instant. Moreover, fee issues are no longer as frustrating as before. Many projects are exploring this direction, and I feel that the market's demand for such scaling technologies will continue to grow.
