Blockchains are public databases. That’s an immediate roadblock for large institutions like banks, whose clients largely don’t want their balances and payments history open to prying eyes. Now, the crypto giant Circle has partnered with the blockchain Aleo to launch a “private” version of its stablecoin called USDCx, which will obscure transaction histories, Howard Wu, cofounder of Aleo, told Fortune.
“People don’t want to reveal their business revenues. They don’t want to reveal business intelligence,” Wu said. “But the way that transparent blockchains work today unfortunately means that every time you transact, you are leaking that data.”
The new Circle-backed token, which like other stablecoins is pegged to underlying assets like the U.S. dollar, won’t be truly private. Every transaction of the token will include what Wu called a “compliance record,” which Circle will be able to access in case law enforcement or other authorities reach out about specific transactions. Still, for public users looking at a blockchain log, the transactions will look unintelligible and like “blobs of data,” Wu said.
“This is banking-level privacy, as opposed to ‘privacy privacy,’” he added.
