  1. Gridcoin Future Technology Base

    Should we Re-Base Gridcoin using Rob Halfords proposal, or should we stay with current codebase and fix it using Piecemeal/Brod proposals? All, From a high level I've been testing cryptocurrency technologies in my lab over the last few months, on an information gathering campaign, and creating some internal mockups and doing budget expirimentation and looking for a way to break through the scalability barriers we have experienced in the Gridcoin client. Finally, I have come to a better understanding of what I believe will actually work in production- and I did not want to finish writing a proposal until that testing was completed and it is now complete. I would like to post a high level proposal to rebase Gridcoin for the future. The intent here is to hold a public vote to see how much acceptance we have with this idea. Specifically, what percent of the community backs This idea VS. going with other piecemeal solutions (those include fixing the current codebase, implementing Tomas Brod's proposals, and in general merging all of bitcoins security commits into the current existing codebase and then maintaining it). So please, read this, and then look for a Poll that I create that will seek to understand the backing level of : Either going with this particular Rebase, or going with Piecemeal fixes+Brods proposals. (Ill come back and edit this with a POLL link later). I have had discussions with Denravonska (our lead dev) (I consider myself CTO for now, and him the lead dev), and iFoggz, CM, and Quez regarding this idea. I checked the viability of this proposal from an IT standpoint and did the due dilligence in the background. I have enough IT support from our back-end team committed that I know we can actually execute this plan if the community wants it. The breakdown is: Rob Halford (me) will push the core, Denravonska (Marco) will push the TCD system, and iFoggz will push the CPID associator system. We think we can do this in 1 quarter. So therefore time is of the essence for us to decide what path we are going. If everyone is on board, this could be the future of Gridcoin delivered by March 2018!

  15. New Coin Launch Announcement - GRC - GridCoin

    All, I'm sorry that I have limited time available today as I have to pick up my son, but I wanted to post a public reply regarding my side of the exchange with Martin Grothe from Ruhr in May. He emailed the original vulnerability in the first paper, one that his college security class was able to reverse engineer the Gridcoin CPID check function and expose Gridcoin email addresses. That led to the realization that the biggest result of this was the ability to steal a CPIDs POR rewards if one was smart enough to create code for a replay attack (May 2017). I worked patiently with Martin for about a week, while Gridcoin devs plugged the issue by releasing beacons and keypairs (keypairs for CPIDs). The misunderstanding started to come into play when Martin explained that his team had come up with a solution that relied on creating a NEW cpid each time a researcher wants to join Gridcoin. I expressed that people have an affinity to the EXISTING cpids as credits are tied to them, and it would be better to have a keypair system that allows the RESEARCHER to choose the CPID. I privately released the version we have now, with the ability for RTM to Delete keypairs using a trusted key (in contrast to forcing researchers to create new CPIDs to use Gridcoin). In a nutshell our communication broke down after this, as his side was threatening to go public with the info, and insinuating that his solution was the only viable solution and that I could not possibly create a viable solution to the problem, while my view was he didnt understand the fundamental operations required over his short hacking tenure - therefore, our talks broke down and I started to consider him hostile. Afterwards, I was not aware of new vulnerabilities or for that matter any publications published anywhere, up to this point. In addition we now have Tomas Brod on board, who has been analyzing the code and committing changes over the last 5 months, which I was under the impression plugged all of our smaller vulnerabilities (that need time to be tested and released as a mandatory). I was operating under the assumption that we have tackled or almost tackled (through unreleased code) everything on our security punchlist.
