By 2025, stablecoins will have completely shed their marginal identity as "digital tokens" and will have officially evolved into a new global financial foundation with a scale surpassing 300 billion USD. The essence of this transformation lies in replacing traditional banks' opaque "credit commitments" with transparent "on-chain code", allowing cross-border capital flows to be as instantaneous and borderless as sending an email, while also embedding automated logic for currency through smart contracts, providing a secure operational base for autonomous finance in the AI era; although there is still a need for refinement in privacy protection and underlying security, this technology-driven shift in financial paradigms is irreversibly ushering humanity into a new era of internet capital markets where assets are programmable and risks are monitorable.
