Cryptopia Announcement

As you may have heard, GRAFT is getting listed on Cryptopia. The trading is schedule to start in a few hours, around 4am UTC on the 18th of July 2018 with the following trade pairs will be available – GRFT/BTC, GRFT/LTC and GRFT/DOGE.

Here’s the original announcement.

Cryptopia is a very reputable exchange located in New Zealand and a solid potential partner for parts of GRAFT network – we’re VERY excited about working with them!

One thing to note is that currently Cryptopia has a deposit wallet set up as a non-integrated address, with payment ID as a separate field from the wallet address. This is an older way to do it and is incompatible with the mobile wallets which expect an integrated ID.

We’re working through this issue with Cryptopia, but for now, the deposits are only available from CLI wallets. (warning: Cryptopia uses paymentID for user identification, so if you try to do a deposit without specifying PaymentID, it will be lost)

ICO Airdrop Clarification

Dear GRAFT Community,

We would like to take this opportunity to clarify the promise we made to the ICO participants to do an airdrop if the price doesn’t recover to the ICO level within nine months.

Why did we do it?

As you might imagine, we’ve never before carried out an ICO, less so an ICO based on a live mineable blockchain. As such, we came up with coin pricing based on what we assessed to be а fair market value (very conservatively at that, comparing to other similar projects). One thing we didn’t know was that the price of the coin would be immediately driven down by ASIC miners, creating a large disparity between the ICO and mining price levels. As project leads we felt compelled to make it right by the ICO participants and to rectify this situation.

Terms of the Airdrop

The following are the terms of the airdrop:

If the price of GRFT doesn’t recover to the ICO level (0.0000262 BTC) prior to November 18, 2018 (9 months from the end of the ICO) for a reasonable period of time (24 hours cumulative, according to CoinMarketCap), GRAFT project team will airdrop the difference in GRFTs to the ICO participants in good standing. The effective price at the time will be determined based on a 10 day moving average.

Example 1 ; September 20 GRFT price is 0.0000262 BTC or higher – no airdrop will take place

Example 2 : October 10 GRFT price is 0.0000262 BTC or higher – no airdrop will take place

Example 3 : November 10-18 GRFT price avg 0.0000131 BTC (and the price hasn’t crossed 0.0000262 BTC before then), each ICO purchase of 1 GRFT will receive ONE additional GRFT via airdrop.

The effect of potential airdrop

The actual number of GRFT’s issued for the airdrop will depend on the price difference between the airdrop and the ICO price (in BTC). The funds will be provided from the undersold ICO funds, and since all the ICO funds were earmarked for circulation, should not result in an increase of the circulation supply.

Furthermore, to avoid “dumping” effect, any airdrop distributions will be spread out over time with exact schedule defined around the time of distribution once all the parameters are known.

Conclusion

We understand the controversial nature of this offer and value community’s opinions and feedbacks. We try to make decisions that are fair to all our supporters, while carrying on the mission of the project. Your support is highly appreciated and valued.

Best Regards,

GRAFT Team

Privacy, Speed and Fees. Part One: Privacy

By

guest post by Nicole DeCicco Owner/Founder CryptoConsultz, LLC

 

Where is our “triple threat” solution to payment processing?

Cryptocurrency enthusiasts are well aware of the problems the crypto economy faces in terms of privacy, speed, and fees. While the blockchain community is scrambling to solve these issues, will the real “triple threat” solution emerge?  

Privacy in a crypto-economy: A blessing or a curse?

As recent megadata breaches show, security is an important element of any payment ecosystem.  We often take privacy for granted and only regret when we lose it. The notion of privacy and data ownership has clearly been brought to the forefront of many industries, most recently and notably social media.  Spring of 2018 has proved to dismantle the previous beliefs consumers held concerning privacy. In March, The New York Times reported Facebook was duped by a developer who reportedly gained access to the data of millions of users.  Reports claimed that such data then may have been misused for political ads during the 2016 political election. In response to the allegations, Mark Zukerburg addressed the media, “We didn’t focus enough on preventing abuse and thinking through how people could use these tools to do harm as well. That goes for fake news, foreign interference in elections, hate speech, in addition to developers and data privacy. We didn’t take a broad enough view of what our responsibility is, and that was a huge mistake. It was my mistake.”

Consumers are beginning to shift discussions about privacy focusing on the risks involved when relying on a central authority to secure our data and protect our privacy. This new era has given users insight to the flaws of a centralized model and the astronomical consequences we might bear through its use. If such breaches have the potential to influence an election, one can only imagine what else we are compromising if we fail to take control of our data.

While often viewed as “anonymous” Bitcoin, Ethereum and many other cryptotokens are not considered “private” due to the open ledger characteristics of their blockchain. Such cryptocurrencies lack privacy due to the traceability of the blockchain and have incomplete security. Ironically, Bitcoin and its derivatives take a step backward in the privacy area compared to older payment technologies like cash or even plastic cards, which became an inglorious symbol of compromised security and privacy. Bitcoin creator(s) either did not think about privacy, or simply did not have enough time to resolve all the problems, understandable as they had an even more important problem to solve: the very existence of blockchain technology.

It’s no wonder cryptocurrency investors find value in various crypto-tokens based on characteristics these particular tokens hold. For investors of privacy tokens like Monero, Zcash, or DASH the ability to use crypto at the Point of Sale (POS) is not only unattainable but undesirable when utilizing a centralized payment processor.

Some industries are solving this problem by accepting privacy tokens for POS transactions. Consumers in industries like adult entertainment, gambling, cannabis and healthcare require that their privacy be maintained. Merchants in these industries see the value in supporting such consumer preferences. Take, for example the recent partnership between Pornhub and Verge which has shifted the future of porn payments.

Corey Price, VP of Pornhub, “Our acceptance of Verge is an affirmation of our dedication to innovation and privacy, which recently has caused much concern and been at the forefront of all tech consumers’ minds,” said Price in a press release. “We’re extremely excited to offer our fans the ability to use crypto and think Verge, with its focus on anonymity, is the best option – whether for privacy, convenience or both!”

Privacy tokens, like Verge, have attempted to solve the privacy issue, some with much success. But these solutions are still not adequate. These same tokens have failed to address other barriers faced when using these tokens at POS, such as speed and fees, which we will discuss in parts two and three of this “Triple Threat” series.

Privacy is a delicate subject for cryptocurrencies and the payment industry in general. While maintaining privacy is important, and in some industries mandatory, there are times that absolute privacy can become a barrier to payment processing.

Privacy demands a range from complete anonymity to complete transparency, as decided by both the seller and the buyer. The seller, for example, may have regulatory compliance requirements to collect and verify certain identity data, like age for liquor/cigarette purchases, or zip codes for online merchant’s tax calculations. The buyer, on the other hand, may or may not agree to disclose all or some attributes of their identity and should be in a position to do so. If the seller and the buyer can agree on the identity attributes to be shared, the transaction can proceed.

Identification, Authentication, and Authorization. In the context of financial transactions between buyers and sellers, some trust must be established between parties. For types of transactions that require regulations and compliances be dealt with, it’s imperative that a good system for authentication/authorization is in place. And yet, such methods have largely been an afterthought of existing cryptocurrencies. The anonymity of cryptocurrency wallets has caused as many problems as it has solved in terms of security.

Identity Proofing. Effective identity proofing is not trivial. To understand the need for identity proofing, consider a merchant that might request a strong level of identity proofing to make sure the buyer is eligible to purchase prescribed medications, and a superior level of identity proofing to purchase arms (as defined by NIST Special Publication 800-63A in the US). Conversely, buyers purchasing goods from an aftermarket might want to protect themselves from buying stolen goods by requesting that the merchant provide a higher level of identity proofing.

Identity Attributes Authenticity. In many cases, there is a requirement to establish an identity attributes authenticity by the merchant. These digital identity guidelines, set out by government regulators, are focused on privacy enhancement. Merchants can benefit from platforms which provide efficient processes for capturing and validating such attributes. It is the responsibility of the merchant to ensure regulation compliance but, in blockchain technology, there is a great opportunity to ease the pain associated with meeting such requirements.

While regulation and compliance are considered dirty words in the crypto-space, projects that tackle these issues headon are poised to be leaders of the industry.

Identity Management. Relying on the wallets to do user management opens up a big security risk as wallets are typically free to implement their own security measures and can be compromised individually. To protect the network and ensure integrity of user identities, payment networks need to support an identity verification function. As such, regardless of wallet implementation, user verification and authentication will be carried out in a manner that will prevent compromised user identities, spoofing, replays, and man-in-the-middle attacks.

The GRAFT Solution

The blockchain industry is seeing several promising solutions to solving privacy at the point of sale. One project that has the potential to transform the industry is GRAFT Blockchain. One unique characteristic of GRAFT is that it employs payment processing protocols and flows similar to how traditional electronic payment systems—such as credit, debit, and prepaid cards—are processed. These processes are already familiar to and trusted by millions of users and merchants around the world. This approach enables easier and faster adoption of GRAFT as a mainstream payment platform while eliminating the need for centralized intermediaries (payment gateways and processors), currently required to facilitate transactions between buyers and merchants.

In order to maintain privacy, one must ensure ultimate security is achieved. Without security, identities can be compromised. Like passwords, once identity is compromised at one juncture it’s compromised everywhere. The highest level of security can be achieved if privacy is at the core of the system rather than an add-on created after implementation is done. GRAFT achieves this through the implementation of a CryptoNote protocol. Privacy components of this blockchain are equally as impressive. GRAFT uses an untraceable blockchain, decentralized API, and an open community of service brokers that support various payment and payout methods, including cryptocurrencies, cryptographic tokens, and traditional credit cards and bank transfers.

Conclusion

The demand for decentralization has brought blockchain technology to the forefront of nearly every industry of the modern day. The centralized approach of yesteryear clearly is riddled with flaws, and its these flaws that have been the fuel behind the fire we call cryptocurrency. While revolutionary, cryptocurrency still isn’t working at the point of sale for various reasons. Attempts have been made to solve problems in terms of privacy, speed and fees, but we’ve yet to see one platform perfect this delicate balance. Even cryptocurrencies that seem to get it right, in terms of privacy, are held back by the dominating forces of centralized exchanges. Absolute privacy is not the answer and can cause additional problems at the POS if not implemented in a manner that allows for an anonymity/transparency range, as decided by both the seller and the buyer.

While some cryptocurrency payment processors are attempting to solve the speed problem, we must look to projects that accomplish this along with solutions to the multitude of problems that exist when using cryptocurrency at the point of sale. To do so while upholding decentralization is a lofty task. That being said, there are exciting projects on the horizon that give us a glimpse into a bright future of the crypto-economy.

Verifone Certification Status Update

After working closely with the Verifone team over the last six months on developing and certifying GRAFT Network integration using Verifone’s brand new Connect application platform, we’re proud to announce passing of the main phase of the rigorous certification process as of the end of last week, making GRAFT one of the first applications on the platform and first one to enable cryptocurrency payments using Verifone’s interactive series payment terminals.

The integration app is running on the RTA Testnet, so not yet compatible with the Mainnet (pending Full Supernode release), and some of the configuration options are pending Verifone platform updates. However, merchants and other eco-system participants can start testing things out in preparation for the launch on Mainnet.

Overall, we’re very happy to be partnering with Verifone, excited about the push into enabling alternative methods of payment and other interactive applications on their formidable new terminal platforms.

The payment terminal space is quickly emerging and going through a transformation of its own, both on the device level with a “Single Unit” (POS/Terminal) conversion and on the software level with application platforms, opening up greater possibilities for innovation!

GRAFT Major Network Update 1.2.1 at Block 68000

We just released a major network update 1.2.1. This update is intended to mitigate recent attacks on GRAFT blockchain and improve the stability of the block intervals. There are two major changes included in this release: timestamp manipulation prevention and improved difficulty adjustment algorithm. The major network update will be triggered at block 68000.

The block timestamp manipulation allows a miner with significant hashrate power to generate an alternative chain of several blocks and add it to the main chain. The corresponding code fix will disable this possibility.

The original LWMA-based difficulty adjustment algorithm used the same adjustment rate to increase and decrease difficulty. As the result, it was taking significant time to restore after a peak, leaving users suffering from a higher difficulty. In our novel approach, we introduce an adaptive adjustment rate, making return to a normal difficulty level faster. The mechanism detects a failing edge of the difficulty curve and change the rate accordingly, using the following formula:

The major network update is scheduled for block height 68000. Each GRAFT network node must be updated to the new software version before that block, otherwise, the node that wasn’t updated is going to be on the wrong version of the blockchain. Major network update means that if you are running the GRAFT network node (graftnoded daemon), you must upgrade it to the current software release as soon as possible. If you do not install the updated node before the block 68000, your node will be blocked by other nodes. Note that the users of GRAFT mobile and desktop wallets (GUI wallets) are not affected by the upcoming network update and don’t need to do anything – as long as they are still connected to the default proxy supernodes (if you are connected to your own supernode, however, do not forget to upgrade the underlying network node).

The source code of the version 1.2.1 is now released and available for download from master. The binaries of the new release are located here:

Ubuntu: https://s3-sa-east-1.amazonaws.com/graftbuilds/graft-1.2.1-20180422-release.tar.gz

Windows: https://s3-sa-east-1.amazonaws.com/graftbuilds/graft-1.2.1-20180422-win-release.zip

In order to check whether you are running the right version of GRAFT network node, launch graftnoded daemon in terminal window (in interactive mode) and type help command. If you are running the right version you should see Graft ‘Beta Lyrae’ (v1.2.1-release) in the first line of the help result.

GRAFT Network Major Update 1.1.2 at Block 64445

We decided to make the major network update even sooner due to the problems with ASIC and difficulty the nertwork has been experiencing over the past several days. The source code of the patch version 1.1.2 is now released and available for download from master. The binaries of the new release are located here:

https://s3-sa-east-1.amazonaws.com/graftbuilds/graft-1.1.2-20180417-release.tar.gz (Linux)

https://s3-sa-east-1.amazonaws.com/graftbuilds/graft-1.1.2-20180417-win-release.zip (Windows)

The major network update itself is rescheduled for block height 64445.

Each GRAFT network node must be updated to the new software version before that block/date, otherwise, the node that wasn’t updated is going to be on the wrong version of the blockchain. This release contains the ASIC-resistance changes in the hashing algorithm and enhanced difficulty adjustment algorithm, which are supposed to protect GRAFT blockchain from most hashing attacks and stabilize the block intervals.

As another reminder, major network update means that if you are running the GRAFT network node (graftnoded daemon), you must upgrade it to the current software release as soon as possible. If you do not install the updated node before the block 64445, it will be disconnected from the mainnet after block 64445.

In order to check whether you are running the right version of GRAFT software, launch graftnoded daemon in terminal window (in interactive mode) and type help command. If you are running the right version you should see Graft ‘Beta Lyrae’ (v1.1.2-release) in the first line of the help result.

Note that the users of mobile and desktop wallets are not affected by the upcoming network update and don’t need to do anything – as long as they are still connected to the default proxy supernodes (if you are connected to your own supernode, however, do not forget to upgrade the underlying network node).

Patch 1.1.1 Has Been Released – Major Network Update on Block 65110

We decided to make the major network update sooner in order to minimize the possibility of hashrate attacks. Patch version 1.1.1 is now released and available for download from master. The major network update itself is rescheduled for block height 65110, around April 14th.

Each GRAFT network node must be updated to the new software version before that block/date, otherwise, the node that wasn’t updated is going to be on the wrong version of the blockchain. This release contains the ASIC-resistance changes in the hashing algorithm and enhanced difficulty adjustment algorithm, which are supposed to protect GRAFT blockchain from most hashing attacks and stabilize the block intervals.

As another reminder, major network update means that if you are running the GRAFT network node (graftnoded daemon), you must upgrade it to the current software release between now and April 14th. If you do not install the updated node before April 14th, it will be disconnected from the mainnet after block 65110.

In order to check whether you are running the right version of GRAFT software, launch graftnoded daemon in terminal window (in interactive mode) and type help command. If you are running the right version you should see Graft ‘Beta Lyrae’ (v1.1.1-release) in the first line of the help result.

Note that the users of mobile and desktop wallets are not affected by the upcoming network update and don’t need to do anything – as long as they are still connected to the default proxy supernodes (if you are connected to your own supernode, however, do not forget to upgrade the underlying network node).

GRAFT Community Mining Pool – Required Miner Configuration Change and Software Update

IMPORTANT UPDATE April 12 – PATCH 1.1.1 HAS BEEN RELEASED – MAJOR NETWORK UPDATE ON BLOCK 65110

GRAFT Community Mining Pool (http://grftpool.com) has been updated to comply with the upcoming major network update which will change the hashing algorithm on April 14 (block 65110). In order to continue mining (even now, before the network update took place) you should update your miner’s configuration (and software if necessary) to be compliant with the recent changes. The new version of the miner with the new configuration is supposed to continue working after the network update as well, without additional changes.

You should change the current mining algorithm setting from “graft” (if you use XMR-Stak miner) or “cryptonight” (for other miners) to “monero7”. If your version of miner doesn’t support this algorithm, you need to update it to the latest version. Almost all popular miners already support “monero7” algorithm.
