GRAFT bills itself as a blockchain based payment processing network that functions similarly to a credit card processing network with off-chain authorizations and in-network atomic swap based interchanges. GRAFT aims to democratize existing payment networks and become a ubiquitous alternative payment network alongside traditional choices like Visa and Mastercard. The network is reportedly decentralized and able to work across borders and regulatory environments.
With respect to Point-of-Sale cryptocurrencies, the project claims to address privacy, speed, fees, and integration. The GRAFT blockchain is a dual-layer (Proof-of-Work and Proof-of-Stake) blockchain with proof-of-stake based authorizations and service broker architecture.
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.
