As the daily trading volume of stablecoins rises to the trillion-dollar level, the issues of fees and congestion on traditional public blockchains become increasingly prominent when handling payment scenarios. A new wave of Layer1 blockchains optimized for the payment track has emerged, with high-performance solutions centered around the PlasmaBFT consensus mechanism attracting market attention.

These payment-oriented public chains adopt a unique technical approach. The architecture based on PlasmaBFT can achieve over 2000+ TPS throughput and sub-second transaction confirmation times, reducing cross-chain payment settlement from minutes to seconds. More innovatively, there is a zero-fee stablecoin transfer mechanism—system-level payment contracts bear the Gas costs, allowing users to complete peer-to-peer transfers and merchant settlements simply by holding stablecoins like USDT. This somewhat simulates the instant usability experience of traditional payment applications and is highly attractive to new Web3 users.

The flexible multi-asset payment design is also noteworthy. Supporting multiple tokens such as BTC and USDT to cover Gas fees breaks the limitations of single-token ecosystems, providing more options for transaction participants. From an architectural perspective, the three-layer design balances performance and security—Bitcoin sidechains ensure asset finality through settlement guarantees, while full EVM compatibility offers migration pathways for mature DeFi protocols like Curve and Aave.

From a market perspective, the high-frequency demand for stablecoin payments and the cost bottlenecks of existing public chains are driving the emergence of specialized solutions. Both institutional funds and individual users are seeking infrastructure that guarantees security while providing a good payment experience. These public chain solutions focused on payment efficiency and cost optimization are becoming an important direction for industry exploration.
