REAL-TIME PAYMENT BLOCKCHAIN

In order to process real-time authorization (instant confirmation) Graft network puts a “lock” on buyer’s account. How does it not violate one of the main goals of any cryptocurrency system – untraceability?

First of all, untraceability is not a feature of any cryptocurrency. As of today, CryptoNote is perhaps the only protocol that enables full privacy and untraceability. The beauty of Cryptonote is that it hides the details of transaction while still preventing double-spending. This is achieved through the use of key image which is unique “fingerprint” that represents the spending address and amount without disclosing any details about the buyer or the amount. By providing the key image for upcoming transaction to the network of supernodes, the buyer’s wallet will temporarily “lock” its “account”, so no other transaction with the same key image can happen until the locked transaction is settled or the lock is removed. If the buyer will try to finalize the transaction with the key image different from the one used in the original lock, such transaction will be rejected by the supernodes. On the other hand, the key image does not contain any information about the buyer, buyer’s wallet, or recipient (merchant). In addition, any traces of communication between the buyer (wallet app), the merchant (point of sale app), and the supernodes (selected proxy and sample supernodes) during authorization phases are completely removed once transaction is settled (written into the blockchain). Even transaction fees paid by merchant to authorizing supernodes are hidden from public view, which is another major privacy improvement comparing to all previous CryptoNote implementations that do not hide transaction fees.

About GRAFT Project

GRAFT is a blockchain based payment processing network the functions similarly to a credit card processing network with off-chain authorizations and in-network atomic swap based interchanges. The network is completely decentralized, able to work cross borders and adapting to local regulatory environment. In addition to decentralization, GRAFT solves four biggest problems that exist in cryptocurrency at a point-of-sale today – privacy, speed, fees, and integration. Technically, GRAFT Network is a two layer (proof-of-work and proof-of-stake) blockchain with proof-of-stake based authorizations and economically incentivized participation with opportunities for mining, authorizations, in-network exchanges, gateway hosting, merchant services, etc.

GRAFT is open-platform, open-source, community project.
Opportunities are available to invest in GRAFT project with additional funds going towards marketing, liquidity (exchanges), additional dev resources, and new initiatives.
