Zero claims to offer total payment confidentiality, while still maintaining a decentralized network using a public Blockchain. Zero aims to combine Bitcoin’s security with Zcash’s anonymity and privacy.
At the core of Zero technology is zero-knowledge proofs, which allows transaction data to be validated without revealing information about the amount and the parties involved. Zero uses specific zero-knowledge proofs called zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge).
Zero claims to be built on strong science and audited meticulously by third parties. It is an open-source protocol, built by a security-specialized engineering team, and based on Bitcoin Core’s battle-tested codebase.
How do I buy cryptocurrency?
While some cryptocurrencies, including bitcoin, are available for purchase with U.S. dollars, others require that you pay with bitcoin or another cryptocurrency.
To buy cryptocurrencies, you’ll need a “wallet,” an online app that can hold your currency. Generally, you create an account on an exchange, and then you can transfer real money to buy cryptocurrencies such as bitcoin or ethereum.
Coinbase is one popular cryptocurrency trading exchange where you can create both a wallet and buy and sell bitcoin and other cryptocurrencies.
