In Web2, we are already accustomed to free services. Sending a WhatsApp message or an email costs zero. But entering the Web3 space is a different story—every transfer and on-chain interaction requires paying Gas fees. This "paywall" has become the biggest obstacle for blockchain to reach the masses and is also why it’s currently difficult to see truly everyday applications.

**How exactly do Gas fees kill micro-payments?**

For example, if you want to spend $0.50 in a game to buy a skin, but the Gas fee is $1; or if you want to transfer $5 to a friend for a coffee, and the fee eats up $2. In this economic model, high-frequency small transactions are completely unfeasible. That’s why current public chains mainly handle large financial transactions and can’t penetrate daily life.

**A technological breakthrough is coming**

Plasma, through innovative network architecture design, truly achieves "near-zero fees"—this isn’t something subsidized by project funding, but a technical solution embedded in the code. For developers, this is revolutionary. They can finally build high-frequency scenarios like social applications, instant messaging, and pay-per-click ads on-chain without worrying about users being scared off by expensive Gas fees.

**The infrastructure for stablecoin payments**

Stablecoins like USDT and USDC are becoming more mature, and there is a need for a public chain infrastructure that can truly support micro-payments. Once the Gas issue is resolved, the application space for stablecoins in daily payments will expand rapidly.
