🔎 Picture this:
João borrowed money from Maria to pay off an urgent debt.
Days passed, and he still hadn’t paid her back. He asked for more time.
😒 But… Maria saw João on Instagram, enjoying a barbecue with friends, drinking beer, and posting stories.
Now imagine that instead of stories, what Maria saw was João’s banking transaction history — public, immutable, on a network like Drex.
💥 The issue isn’t whether João is right or wrong. The problem is that full exposure can lead to judgment, conflict, and irreversible consequences.
🏦 Now swap “João” for an individual, a small business owner, or even a strategic company.
Swap “Maria” for a competitor, a rival financial institution, or a potential creditor.
If everything is public:
Banks can sniff out high-value clients and offer better rates.
Companies can cross-reference competitors’ financial data.
Personal purchases become targets for judgment or discrimination.
This isn’t fiction. It’s what happens when CBDCs or tokenized assets are placed on public networks without any privacy layer.
🔐 The challenge is that networks like Drex are designed to be transparent and auditable.
Adding privacy without compromising consistency or trust is extremely difficult.
Even large companies, with massive teams and resources, haven’t delivered a viable solution.
That’s why we built Harpo.
✅ A solution based on Zero-Knowledge Proofs (ZKPs) that enables:
Transaction privacy
Selective auditability by authorities
Full consistency with Drex’s model (no sidechains, no total opacity)
⚙️ Harpo is the result of applied research, engineering, and sheer stubbornness.
And most importantly: it works.
