GRAFT - Real Time Payment Blockchain
Graft Blockchain is built on the idea that the payment industry can benefit tremendously from the democratization brought forward by the #blockchain technology, but only when the right technologies are chosen and combined with the accepted indusrty workflows and systems.
When done correctly, this transition to blockchain-based payments will lead to radically improved credit / debit payment system through the combination of lower transaction fees, tight privacy controls, low rates on credit balances, and connected extra services.
Graft Blockchain introduces a decentralized, real-time payment processor and services platform into the global market convering a wide variety of #credit and #debit payment use cases.
Key Features
Real-Time Transactions at Pos with Zero User Fees
The transactions are near instant and the fees are paid by the merchant, proportional to the transaction amount (about 1/5 to 1/2 of the credit card fees would be)
Open and Decentralized - Uber of the payment industry
Anyone can become a gateway, exchange broker or merchant service provider.
Unmatched Flexibility on the User Side

Merchant Payouts in Local FIAT Currency
Transaction are settled in real time and payouts can be received in local currency.
Privacy at the Core
CyrptoNote protocol ensures full untraceability, unlinkability and fungibility of Graft blockchain, where sender address, recipient address and transaction amount are cryptographically protected and invisible.
Integration with Leading POS Terminal Providers
Graft does not require own POS terminals, as implementation into existing ones is simple. #Verifone and #Ingenico partnerships are just beginning of world wide adoption.
