Anonymous phone service Phreeli has launched in the U.S., offering users the ability to register with just a postal code, eliminating the need for personal or payment data. Zcash co-founder Zooko Wilcox advises the service, which utilizes zero-knowledge access passes and the Double-Blind Armadillo encryption system to verify billing without storing payment information. Users can pay using credit cards, Zcash, or Monero. Phreeli, founded in 2019, aims to combat data collection by mainstream carriers. The company has raised $5 million in the past year and operates on T-Mobile's infrastructure. Founder Nicholas Merrill emphasizes the service's commitment to privacy and data protection.
