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.”
