summary
Cryptocurrency records 27.6 trillion dollars of stablecoin transfers last year yet under 0.01% is end-to-end encrypted, so public ledgers expose purchases, salaries, and vendor histories. Early fixes like CoinJoin and Tornado Cash suffer gas linkability and compliance risk; Monero and Zcash lack stablecoins and configurable rules. Aleo is a private-by-default blockchain with view keys, private smart contracts, ZK proofs, verifiable credentials (Zpass), policy engines (Predicate), and conditional escrows to balance privacy and regulatory access.
