MVP Development Status Update

We would like to update the community on the status of Graft blockchain development. We have made a lot of plans and promises, and now it’s time for our dreams to start coming true. In order to achieve our ambitious goals, we have put together an efficient team of very talented and experienced developers. Two of them came from Monero project, which is very important for us as we forked the blockchain from Monero, and there will be many blockchain protocol changes.

Network Node, Testnet, and Blockchain Explorer

As an important milestone, we have finished some initial blockchain code modifications which allowed us to set up a public testnet with the first Graft block explorer.

While the testnet is open for access from the Internet, we have not published yet any information on node/supernode setup, configuration, and connectivity since we are still frequently updating it, and we would like to make sure it is stable enough to be open for public view and alpha testing. We will notify everyone once we publish the instructions so anyone will be able to connect and test the basic network.

Supernode

The majority of the work, however, currently is concentrated in supernode code which is — unlike network node forked from Monero — being designed from scratch. The proof of concept supernode was written in Python for the sake of rapid prototype development. After thorough review, the team decided to refactor the supernode code in C++ in order to keep a single technology stack and optimize the development process and network performance. Although the supernode and network node are based on the same technology stack now, the supernode is still deployed as a separate process (daemon), and we intend to keep it this way, at least for the near future.

Mining

Also, we are working on instructions for miners, including GPU and mining pools. Initially, it will be possible to mine on CPU, so the entire full supernode can be hosted on single machine. That’s how the typical testnet supernode is configured. On the mainnet, however, the network hashrate will grow fast, which will require GPU, then multiple GPU, and eventually mining pools to be set up in order to efficiently mine and maintain the full supernode. We are working on providing instructions for GPU miners as well as creating a first mining pool. The GPU mining machine can be detached from the supernode, which enables a hybrid “on premise/cloud” configuration, where, for example, the GPU mining rig is located at home while the supernode is hosted in AWS.

Mobile Wallet, Point of Sale, and Payment Terminal Apps

Finally, we are working on development of client applications, which include wallet and point of sale mobile apps that should look familiar from the PoC phase, as well as new apps running on payment terminals such as Verifone, Ingenico, Equinox, and AnywhereCommerce. Those new apps are going to be different from our existing mobile apps as they are going to be tailored to particular terminal hardware/OS/API/SDK and mostly integrated with third party point of sale software. The terminal apps are very important as they will open the door to the mainstream merchants including top tier retailers. Here is how the typical terminal app will interact with Graft blockchain:

We are still on initial design phase with those apps, but we believe we will be able to demonstrate the working prototypes before the ICO. Stay tuned!

Graft vs Ripple and Others: Focus on Buyers, Merchants, and Their Privacy

Focus on Buyer and Merchant NeedsRipple’s is mostly focused on bank settlements, while Graft provide solutions to buyers and merchants. Buyers can pay anywhere with cryptocurrencies or plastic card using Graft wallet app. Merchants can receive payment from anyone using point of sale accepting both cryptocurrencies and plastic cards. Faster payment confirmations are provided by Graft supernode authorization sample, a process that is more similar to Dash masternode scheme. Unlike Dash masternode, however, Graft supernode is not a “wrapper” or a second tier as it is designed to be a monolithic code base that implements both real time authorization and blockchain settlement (mining) features. Such an architecture improves security of the real time authorization process, as payments cannot be settled “off supernode chain” by the “lower” level blockchain network nodes, without supernodes knowing about their existence. Thus, all Graft transactions are authorized instantly without requiring additional fee, by supernodes that are automatically selected by the network using combined proof of work and proof of stake algorithm. Focus on Absolute Privacy Ripple consensus protocol is different, and its main problem is that it does not provide privacy features: untraceability and unlinkability of payment transactions. Unlike Graft blockchain, all transaction information on the Ripple ledger is public. Ripple does not provide the privacy and untraceability that are demanded today by potential Graft users – both buyers and merchants. When we pay with credit card, we share our secret payment information (like credit card number) with some entities – the merchant, the issuing bank, the payment processor, the payment acquiring bank – but those entities are relatively trustable so they try not to share our secrets with the entire world, and no one else can see our transaction history without our or their permission. Oftentimes, however, they fail to keep our secrets (think Target and many other retail mega breaches). With Ripple or Bitcoin or most other cryptocurrencies that are not based on CryptoNote protocol, the story is exactly opposite: there is no central authority that “knows” our secret “card number” (private key), but at the same time anyone in the world can trace our payments on the blockchain and link them to our identities with minimum efforts. By Implementing CryptoNote and other features, Graft brings the level of untraceability of payment history similar to traditional credit and debit card system, while adding decentralization, privacy, and security, which are the features of any cryptocurrency that are absolutely impossible to achieve using traditional credit card payment technology.

Since Graft uses CryptoNote protocol, has the Monero community indicated support for Graft?

While Graft supernode code is being written from scratch, the blockchain CryptoNote implementation codebase is forked from Monero. We do not anticipate a direct and immediate Monero community support. However, we believe that our project attracts people from CryptoNote communities as it adds a lot of features that are not available in existing CryptoNote implementations. One example of such a feature is real-time authorization (instant confirmation). Another example is hidden transaction fee amount, which is exposed to public view in all existing blockchains. This table compares Graft with Monero, Bitcoin, Dash, and other cryptocurrencies. However, there are even more important features that are not simply enhancements of the CryptoNote protocol. No one needs just another blockchain, even if it provides better privacy. But Graft is much more than just “another blockchain”. Graft is innovative payment application platform which supports various payment and payout methods, either traditional or innovative. While providing “reference”, default implementations of applications and services, Graft ecosystem is open for any software vendors and service providers. We believe in diversity of payment methods and cryptocurrencies.
