Privacy isn’t complete if it only hides who was involved. True financial privacy also means hiding how much was sent.
Most blockchains — even many privacy-focused ones — still reveal transaction amounts. Anyone watching the chain can see how much money moved, even if they can't always tell between whom. This leaves patterns, clues, and vulnerabilities.
Halo 2 closes that gap. Using a cutting-edge cryptographic system, Xcoin makes sure transaction amounts are as invisible as the participants themselves.
Halo 2 is a type of zero-knowledge proof — a mathematical technique that lets the blockchain verify a transaction is valid without knowing the amount involved. You can prove something happened, without revealing what it was.
It works like a sealed envelope that says:
“This payment is real, and the math checks out — but you’re not allowed to look inside.”
That means no one can tell if you sent 0.01 X or 1 million X. There’s no way to distinguish large payments from small ones, and no way to match payments across time.
Many privacy systems rely on a "trusted setup" — an initial phase where someone generates secret keys that, if misused, could break the whole system.
Halo 2 doesn’t require that. There’s no backdoor. No central authority. No hidden risk. It uses recursive, hash-based techniques that can prove transactions at scale, securely and transparently.
Halo 2 also enables range proofs — cryptographic checks that confirm the amount follows basic logic:
These checks confirm validity — without ever disclosing the actual amount.
In Xcoin, Halo 2 works side-by-side with stealth addresses and zk-STARKs to ensure that every transaction is fully private — sender, receiver, and now amount.
There’s no configuration, no toggles, and no way to “accidentally” expose information. The system does it for you, automatically and by default.
Because if someone knows what you paid — even if they don’t know who — they can still make dangerous assumptions:
Halo 2 eliminates that visibility. It doesn’t just obscure your balance — it makes the entire concept of financial transparency opt-in, not default.
In the world of Xcoin, the blockchain says yes or no — never how much.
