Last night, I was taught a lesson by gas fees again. I executed a trade on a certain DEX, and the fees directly swallowed my profits and even made me lose money. In these moments of collapse, friends who play on-chain should understand.

But I recently discovered something that might really solve this long-standing problem.

**Sidechain Solutions: It's Not Just About Saving Money**

When I first encountered the Plasma architecture's sidechain, to be honest, I was a bit skeptical. The cost of the same operation dropped directly from $20 to $0.01. This isn't just an improvement; it's a completely different way of playing.

To make an analogy— the mainnet is like a toll booth in the city center, where you have to pay every time you pass through. The sidechain is like a fast lane opened in the suburbs, where you usually drive on the fast lane, only returning to the city for important checkpoints. It's both fast and cheap, and the key is that the necessary security is not compromised at all.

**Tested with real money**

Last month I conducted a stress test on a game side chain. I executed 47 item transactions in a row, and the total cost was less than 1 dollar. If this were done on the mainnet, this budget would probably not even cover 10 transactions.

What is more reassuring is that all assets are ultimately anchored back to the Ethereum main chain. It's like enjoying convenience while doing business at a branch, but the security level of the money still follows the standards of the head office.

**Why are all the on-chain games heading this way?**

Data doesn't lie—now more than 60% of blockchain games have chosen architectures like Plasma. The reason is actually quite straightforward:

- Small payments of a few cents can finally be realized.
- The transaction confirmation speed has increased by more than one order of magnitude.
- Underlying security or mainnet-level protection

For regular players, this is the technology that can truly be used. After all, no one wants to spend dozens of dollars on tolls just to buy a game skin, right?
