I've been really frustrated lately with the high transaction fees. Last week, I wanted to adjust my small-cap token positions, and when I tried to swap, the system popped up a fee of $2.3. This number is embarrassing—an American coffee at the convenience store downstairs costs only $1.8, yet a small transaction's fee exceeds that, and what's more ridiculous is that it takes ten minutes to settle.

Honestly, I guess every player has experienced days like this. The gas fees on the ETH mainnet are outrageously high, and during BSC congestion, a single transaction can easily cost one or two dollars in fees. This phenomenon directly discourages small-scale traders like us. Want to try a new project? The fees give you a cold shower first. Want to do small arbitrage? The tiny profit margin isn't even enough to cover the gas costs. I even gave up on several good NFT projects because the combined minting and transfer fees destroyed the entire profit expectation—not because the projects had issues, but purely because the cost structure was too high.

Until I started researching Sui ecosystem projects and discovered Walrus. This isn’t some rebranded new chain; it’s a real solution that can push transaction fees down to the floor. After launching on the mainnet at the end of March, I used it for a month, and the results were truly different.

The core technology is zero-knowledge proofs (ZK), but Walrus’s implementation is more thorough. Simply put: previously, each transaction's data had to be verified on-chain one by one, like unpacking each item in a package to show the courier; ZK’s approach is to generate an authoritative receipt that just needs to tell the main chain, "These transactions have all been verified, no problem," which significantly improves efficiency and reduces costs.
