A "Physical Shield" for Digital IDs: Zero-Knowledge Proofs (ZK) The concern with digital IDs is their ability to link "who did what, when, and how much." The solution to this is now being integrated into the XRPL (XRP Ledger): **Zero-Knowledge Proofs (ZK)**. • What it enables: A technology that proves only the fact that "I have the ability to pay," without revealing any details about my balance or transaction history. • Movement in 2026: This month (April 2026), news emerged that ZK infrastructure is being integrated into the XRPL. As a result, institutional investors are beginning to realize the "best of both worlds" that CZ highlighted—complying with regulations while maintaining complete privacy. 2. The Revival of Privacy in Cryptocurrency CZ’s critique of "too much transparency" is no longer just about privacy coins like Monero—it’s evolving into an **infrastructure-level upgrade** across major cryptocurrencies. • Stealth Addresses and Confidential Transactions: Even on XRP, features like "confidential transactions" that conceal specific transaction amounts or counterparties are currently being tested. • Whales’ Escape Route: Whales, too, want to avoid being tied to digital IDs. To protect their assets, they are building privacy layers—such as sidechains—on top of public blockchains as a "camouflage." 3. Decentralized Identity (DID) as a Countermeasure to Digital IDs To counter the forced adoption of digital IDs, we are preparing to adopt **self-sovereign identities (Decentralized IDs)**. • Centralized ID: An ID issued and revocable by the government. • Decentralized ID: An ID stored on a blockchain, accessible only by the owner. The strategy to avoid digital IDs isn’t just about rejecting government-issued IDs—it’s about mastering privacy-preserving technologies within government-independent economic ecosystems like the XRPL.
