As we mentioned in the previous communications, we are launching an IndieGogo campaign for the ColdPay card.

Why we’re doing this and why now?

In order for the network to gain the momentum as quickly as possible we need to create awareness and “pull” from both sides of the marketplace. What better way to reach the first potential users and influencers than a cool multicurrency cold wallet / payment card – something that they will initially use to make their cryptocurrency wallets safer and eventually use for payments.

With the campaign now and a first batch scheduled for late May / early June, we’re looking to create some good buzz in the marketplace shortly prior to, during, and shortly after RTA Mainnet launch (not to mention putting a useful product into people’s hands that reminds them of GRAFT).

Impact on RTA development timelines

ColdPay leverages the same development investment that we have to make for the mobile wallet and POS support, including web wallet and payment gateway, so from that standpoint we’re not incurring additional development overhead.

There’s a limited amount of specialized development both on the card and one the provisioning interface, but that work is confined to several part- time engineers who do not participate in core development. So overall impact on the critical path core development is minimal.

Participating in ColdPay IndieGogo campaign

The campaign is now OPEN! There’s a first 100 card Early Bird Secret perk we’re making available to the community.

Often times as engineers we have a tendency to wait to release something until it’s complete and final. This however is not always practical, especially when it comes large complex projects like RTA Supernodes.

We have given it a lot of thought over the last few weeks and decided to break up the Supernode release into two phases. While we’re continuing the work on fine tuning RTA workflow and communication protocol in preparation for mainnet beta, we will first roll out what we’re calling an “RTA Miner” – an RTA Supernode that stakes, participates in RTA communication, and gets revenue from the stimulus transactions.

Goals

This release will allow us to:

• Test the supernode concept on the scale of real network (there is a limited number of alpha supernodes)
• Fine tune the economic model including stimulus distribution model
• Draw attention to the project (enter masternode listings etc.)

Scope

• RTA transaction will not be enabled in wallets and POS clients (only stimulus transactions will be enabled, but they do not require GUI clients)
• No requirements to RTA TX performance (time, fault tolerance, etc.) or security (double-spending) as stimulus RTA Tx will be processed by GRAFT team only (Stimulus Tx is sent between GRAFT wallets)
• There will be no security risk to supernode owners or to the entire network

Incentive Details

We’re currently targeting a 5% avg. per month ROI in RTA mining income based on the stimulus program we had announced earlier. Stimulus incentives will carry into the RTA Mainnet launch (tentatively April 2019) until the network is fully ramped up.
The calculation is based on 1,000 active Supernodes

Timing

We haven’t set an exact date for this release yet, but expect it to be within the next 3 weeks, pending release and testing of the supernode staking wallets security issue fix.

Have a burning question about the GRAFT Network? Marketing plan? Adoption? Community involvement? Technical questions? Submit your question(s) and get an answer! In a continued effort to increase engagement with our community and educate the market, the GRAFT Team will be hosting an AMA live on Telegram and Discord on October 18th, at 12pm EDT.

Questions will be categorized and collected through a Google form to make the best use of time and format.

* PLEASE SUBMIT ONE QUESTION AT A TIME. You will have the opportunity to post another question after submission. This allows us to keep the questions concise, organized and minimize duplication.

SUBMIT QUESTIONS HERE: https://goo.gl/forms/10VVUaqcWqp9Kg2y1

FORMAT:

• Questions will be moderated by our Discord Community Manager, and answered by GRAFT devs.
• Q&A will be delivered simultaneously on Telegram and Discord via the GRAFT Bridge Bot.
• We have an hour for the AMA. Will try to get through as many questions as we can, with target of 20. The remaining questions will be held over for the future monthly AMA rounds.
• Afterword, a summary will be posted to the GRAFT blog, and then pushed to all social media channels.

Happy GRAFTing!

As previously announced, we have released network node version 1.4.2 (“v10”) for a major network update. This update will correct the emission curve by reducing block rewards by 50% starting at block 176,000, which will be reached around September 17, 2018.

The new block reward formula will be as following:

reward = (M – A) * 2^-19 * 10^-10 / 2

Where M is the maximum total supply and A is the current supply.

This correction will not change the maximum supply of GRAFT that will be ever created, it will just stretch the emission curve such that it will take longer to mine the maximum supply. All GRAFT supporters should benefit from the corrected emission formula because it will stabilize the growth of the circulating supply.

In addition, GRAFT v10 will drop the mining difficulty algorithm adjustment made in the previous (v9) major network update (LWMA+tweak) and return to a standard LWMA difficulty calculation. The adjustment was originally added in an attempt to make the difficulty drop faster after a network attack, as it was believed that such network attacks were responsible for block delays and network stalls in the turbulent days between the first (v8) and second (v9) major network updates. As it turned out, however, those issues were caused by an unrelated bug inherited from Monero and have been long-since fixed on Graft’s network (the fix did not require a fork).

In retrospect, the v9 algorithm adjustment had the unintended side effect of inducing larger swings in mining difficulty because it made difficulty drop too quickly. Over time, opportunistic miners learned to exploit those difficulty swings by mining on the graft network with huge hashrates whenever difficulty dropped to win a handful of low-difficulty blocks, then leaving the network as soon as difficulty increased again. This would, in turn, result in long block times that would then trigger another difficulty drop, thus repeating the cycle. While such difficulty shifts are unavoidable, the v9 difficulty adjustment made the swings a little worse and are being removed in this fork to help make the mining difficulty more stable.

The major network update means that each GRAFT network node must be updated to the new software version before the specified block/date. Otherwise, any node that isn’t updated will be on the wrong version of the blockchain. The source code and the Linux and Windows binaries are currently available for download. The installation instructions are unchanged.

As another reminder, a 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 block 176,000, it will be disconnected from the mainnet after block 176,000.

Note that the users of GRAFT mobile and desktop wallets will not be affected by the upcoming major 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 to stay on the right network).

Exchange Brokers are a critical component of the system, paving the way for pay-how-you-want-it / receive-how-you-want-it capability. Exchange brokers (pay-in / pay-out / interchange) are open to both large and small participants. Watch the new video from All Things GRAFT about how the exchange brokers work
