That's really cool. Excited and looking forward to PoC and MVP. It will help people to get a clear impression of what you are building of course. I think that's always helpful.

Updated Graft website is live!
https://www.graft.network/

Once the production network is up and running. We are planning to do it after pre-ICO but before ICO.

Actively working on PoC and MVP.
https://github.com/graft-project

Mobile Wallet app and Mobile Point of Sale app PoC will available for download within days, it will be announced.
The reason for pre-ICO is to get funds to speed up the development of mobile apps, supernode, finish necessary network protocol modifications, and launch the production network beta.

So far do you only have a  white paper or also an alpha version? Would like to get an impression of the platform in action. Can you make that available or is it already somewhere accesssible?

When can we start mining?

Q: Is Graft payment more secure and private than Credit Card payment?

A: It depends on how you pay or accept payment. Graft platform offers multiple ways to pay (for a buyer) as well as various methods of accepting payment (for a merchant). if buyer pays by Graft plastic card linked to the buyer’s Graft cryptocurrency wallet, he or she relies on merchant, merchant’s payment processor, and acquiring bank, who are not always the best experts in keeping our data safe (remember all those endless mega card data breaches like Target). However, If such a card payment is accepted by a merchant that also uses Graft network and Graft point of sale app, this payment is more secure and private because the Graft card is recognized and handled by the Graft network as internal transaction. This is almost the same as paying with GRAFT itself (graft coins). “Almost” because there are still some “standard” risks associated with using a plastic card, even Graft card, since the card is issued by a centralized institution (otherwise, it wouldn’t be accepted everywhere, including merchants who don’t work with Graft network yet). 

GRAFT (coin) is the most secure, private, and least expensive way to transfer funds (although it is important to note that payment is always free for a buyer, because Graft is the only platform that charges transaction fees to the merchant just like in the “real world” of payments, but there are also "authenticated" transfers that are absolutely free for both sender and recipient). GRAFT is the most private and secure way to pay because the payment does not leave the network where all the elements of transaction - sender address, recipient address, transaction amount, and even transaction fees - are encrypted and hidden from public view. Nevertheless, Graft blockchain is still public, and transaction is validated by multiple supernodes. Such a level of security and privacy is achieved by using CryptoNote protocol and additional technology designed by Graft.

Is this a one-person project? If not, any info about the team?

Thank you for your support. Let us know if you have any questions about the project.

GRAFT pre-ICO just listed on coinschedule
https://www.coinschedule.com/icos/e836/graft-pre-ico.html
15 days before start, you can still make a "soft commitment". Pre-ICO will be on "first come / first serve" basis and subject to hard cap. To indicate interest and reserve (soft-commit), please send us your name, email, phone number, and the amount to [email protected]

looks so promising project, I think for now there is so many option that we can choose to joining one of project that we believe, for me I will think about this project later

Graft mobile wallet and point of sale apps do not maintain a full copy of the blockchain for obvious reasons. Does it mean the wallet content is stored on supernodes which may compromise its security and privacy?

There are multiple elements of the Graft user wallet:

• Private spend key - secret - required to spend money; stored in the wallet app
• Private view key - "semi-secret" - required to see the balance and previous transactions
• Payment address - public - required to receive money

In Graft, the Private spend key is always stored at the client (wallet) and never shared with the supernodes. Therefore, it is not the same as credit card when you share you card account number with the merchant, payment processor, and the bank every time you make a payment. If one of them is breached, your credit card can be stolen and used to make fraudulent payments. If any or even all supernodes are “breached”, they don't have your private spend key so no one will be able to "use" your Graft account.

The Graft wallet balance is a “hidden” set of previous transactions. It is calculated by scanning all the previous transactions which are stored on the public blockchain but invisible without view key. Since mobile wallet app does not have direct access to the blockchain, the private view key is temporary shared with a single "proxy" (relay) supernode in order to retrieve the wallet balance; the supernode will not store this view key in any database so even if it's “breached” the view key will not be disclosed in most cases. However, even if the view key is disclosed, it only allows to see transactions, not to spend any money.

Users (either buyers or merchants) with higher requirements for privacy can host their own private "proxy" supernode with full copy of blockchain. This way they will never share their view keys with the random "foreign" supernodes. Most probably, due to limited processing power and other resource limitations, such a private proxy supernode will not be able to participate in transaction processing and earn any block rewards or transaction fees, but it will still be able to validate transactions and view balances privately by scanning the local copy of the blockchain. For users who cannot or don't want to host their own supernode but still don't trust the entire network, Graft creates a special (free) cloud service with trusted proxy supernodes that are protected by multiple levels of security.

Thank you for supporting Graft project!
In addition to obvious benefits for buyer, there is always another side of the transaction - merchant. We provide merchants with the ability to accept both crypto and cards using the same mobile point of sale app.

Actually we do have bounty for signatures:

But there is no active campaign yet. We posted a message in Marketplace (altcoins) asking for help with signature design and signature campaign. Did not get any offers yet.

We will appreciate any help with signatures.
If you have any ideas or offers please reply here, send PM, or email to [email protected].

Like this project a lot, since the coin holder will have a physical credit cards.
It will give flexibility for all the coin holder if they wish to make use of their coins.

I totally agree. We posted a message in Marketplace (altcoins) asking for help with ann thread design. Did not get any offers so far.
https://bitcointalksearch.org/topic/m.21195155

Our professional designer is currently working on image version, but he does not have bitcointalk experience. If somebody can point us to instructions or something, we will appreciate any help.

While learning about this project better than ever, then it would be great if we put some lines on what to perform at the moments.

Thank you for your interest in Graft project!
