EDIT: We have edited the article based on community feedback. Thanks for all the feedback!
Hello!
Join us in welcoming the Gridcoin Network to Medium! @geebell and myself have begun to put together a series of posts on Gridcoin and the Network, BOINC, BOINC projects, and more. We plan to have new posts published on every other Monday, beginning on the 1st day of 2018. The next post is titled "An Introduction to BOINC." Below is the link to the first post along with its text. Hopefully this endeavor will extend awareness of Gridcoin into an entirely new community. Let us know what you think.
Here's to the continued growth of Gridcoin!
Give us a follow here.
An introduction to Gridcoin
Gridcoin is an open source transaction blockchain that mints and distributes cryptocurrency with relation to the processing power users direct toward data driven analysis and scientific discovery. The Gridcoin blockchain is currently secured through a proof-of-stake protocol and monitors processing contributions to the distributed computing infrastructure, BOINC. BOINC, the Berkeley Open Infrastructure for Network Computing, hosts major citizen science computing projects such as IBM’s World Community Grid, SETI, and the Large Hadron Collider, alongside projects developed by students, enthusiasts, mathematicians, researchers, and citizens.
SETI@Home
SETI@Home was launched as a distributed computing project in May 1999 by the Berkeley SETI Research Center. It operates by packing data recorded in the 2.5 MHz wide band of the SERENDIP IV instrument into “work units” to be analyzed by the idle processing power of volunteers. After analyzation, the completed work units are returned to SETI@Home servers in california. This concept was developed further in 2002 and resulted in the BOINC software being released in 2004.
BOINC
BOINC is an open source distributed computing infrastructure which provides anyone with the means to process data via a global volunteer based distributed computing network. BOINC has been used to identify pulsars, create patient specific cancer treatments, expand on our knowledge of efficient molecular combinations for solar panels, and complete countless other scientific and mathematical computational tasks. While BOINC has been used primarily for science and math, it can host data from any field so long as the data can be formatted for BOINC’s processes. Examples of projects include tasks on engineering, rendering, weather and climate prediction, and social, market, and resource analytics.
The Financial Crash of 2008 and Bitcoin
As a result of the 2008 financial crash, many groups and individuals pushed for alternative financial systems which would help prevent similar disasters in the future. A pseudonymous individual or group known as Satoshi Nakamoto was one of them. They seem to have worked under the assumption that a principal problem of the contemporary financial system can be traced back to the system’s reliance on centralized middlemen entities. Following these assumptions led to their creation of blockchain technology with the bitcoin cryptocurrency as its incentive mechanism. Blockchain technology uses cryptography to ensure a public and unforgeable digital cash system that does not need to rely on any middleman entities. The cryptographic method used to secure the public ledger requires individuals to use processing power to solve complex hashes. This process, known as proof-of-work, works, but accomplishes nothing beyond securing the bitcoin network, thereby moving the ledger forward. Over time, alternative processes for securing the public ledger were and continue to be developed. Nakamoto released their blockchain technology through an open source medium. This allowed thousands of individuals and entities to examine, learn from, and improve upon the code and protocols of the technology.
Gridcoin
One such entity was the pseudonymously named Rob Halförd. They took the concept of the blockchain and altered its incentive structure to create an entirely novel protocol which marries the second blockchain protocol developed, proof-of-stake, with a cryptocurrency generation mechanism based on processing contributions to BOINC.
Genesis
The Gridcoin blockchain was genesised on October 16th 2013. It started with a proof-of-work protocol based off of Bitcoin. On October 11th, 2014, Gridcoin was forked onto a proof-of-stake protocol which secures the blockchain based on the number of active GRC on the Gridcoin network. Gridcoin has evolved through several iterations of proof-of-stake and incentive structures. Currently, it uses proof-of-stake to secure the blockchain while using processing power contributed to approved BOINC projects to mint the cryptocurrency, GRC. To accomplish this, Gridcoin developed a tool defined as a superblock which collects and records each Gridcoin participant’s contributions to BOINC. This data is then translated into the Gridcoin variable known as magnitude, which then determines how much of the planned GRC minted each user receives.
Minting Gridcoin
Gridcoin mints about 27,000 GRC through research a day. This GRC is split evenly among approved BOINC projects. The Gridcoin Network Each BOINC project then distributes each project's allotted GRC among its participants relative to each participants contribution to that project.
Currently, additional minting occurs through an interest structure that awards 1.5% annual interest to each GRC in circulation.
Superblocks
Currently, a Gridcoin block contains information pertaining to transaction data between users participating in the Gridcoin blockchain. In addition to these standard blocks, Gridcoin compiles records of individual performances on projects and events provided by third-party data sources into a superblock. Superblocks maintain all of the qualities of standard blocks including immutability based on consensus. Currently, superblocks contain information related to credits awarded by projects utilizing the BOINC computing management platform, representing the completion of analysis of sets of data provided by the project. Each superblock thus contains unique user information regarding the processing power that a user contributes to BOINC projects. Superblocks have the theoretical potential to collect statistics from a vast array of sources so long as those sources are capable of ranking individual contributions or performances and can provide that information in a suitable format.
Rain
Rain is a unique feature to the Gridcoin Research wallet. It permits anyone to distribute a set number of GRC among participants of a particular BOINC project. Ultimately, rain is intended as a tool in the Gridcoin ecosystem which helps distribute magnitude across BOINC projects. We intend to explore this ecosystem in more detail in a future post.
Rain is a unique feature of the Gridcoin Research wallet. It permits anyone to distribute a set number of their GRC to the participants of a particular BOINC project. This has the potential to draw more participants and their computing power to that project. We intend to explore the way Gridcoin utilizes this feature in a future post.
Voting
Gridcoin utilizes a voting system built directly into the Gridcoin Research wallet. Any community member or developer with a significant stake in Gridcoin (currently 100,000 GRC) can create a poll. A poll can be made to weight a vote based on a user’s stake, contributions to BOINC, or both. Additionally, a poll can be made to weight votes through a one-wallet-one-vote or one-CPID-one-vote mechanism.*
*A CPID, Cross Project ID, is a tool that is assigned by BOINC. Gridcoin uses it to distribute GRC to the appropriate user. This will be explored further in another post.
Conclusion
We hope you enjoyed this brief summary of the Gridcoin Network. There is, of course, much more to Gridcoin. Join us in the future as we explore different aspects of the Gridcoin network and community in detail. If you would like to see anything specific explored further, feel free to leave us a comment and we’ll see what we can do!
Rain is not distributing magnitude, it's distributing GRC according to magnitude
I'll make sure that we give clarity to this mistake.
While writing, that statement was meant to convey that raining on a project can draw attention and / or additional crunchers. It was poorly worded though because the understanding you got (and I also see now that you have pointed it out) was that the rain itself distributes magnitude to the user. This was not the intended meaning.
We rewrote a good portion of it (changes italicized and bold):
Does this edit fit with how you view the rain feature?
It's a tool that is used to move magnitude between projects. Magnitude may be the wrong word. Crunch power.
When I say, "I'm going to RAIN on project X." Magnitude, crunch power, moves accordingly.
Rain is a tool to move GRC i.e. cryptocurrency i.e. money. You should fix that mistake. "Crunch power" may eventually move after the money, but it's not guaranteed in any way.
Uhm, this is a mistake. Why are you distorting the truth about how the system functions?
Total magnitude is fixed for each project, as it is split evenly between the whitelisted projects. That is how GRC is fairly distributed between projects. Nothing can change that. Rain has zero effect on magnitude.
Easy with the accusations = ). A conversation would be far more productive.
I openly admitted that we may have used the wrong word. The intent is "crunch power." We will address this when we can.
Do you think that rain is not a tool of the ecosystem regarding how Gridcoin seeks to spread IPP across projects?
Comprehensive post. Found a small typo in it tough.
It can easily be mistaken that it's the projects itself that does the distribution. As this is not the case it would be good to change this sentence.
For clarity this has been adjusted to:
"The Gridcoin Network then distributes each project's allotted GRC among its participants relative to each participants contribution to that project."
Good point. Thank you! We will discuss how to make this clearer as soon as we can.
Thank you for taking the time to put all this together, as always!
Is the rain feature active yet? If so, is there an example of someone using it?
The rain feature is 100% functional and used extensively. It can only rain on whitelisted projects, but @scalextrix wrote a Python script that lets you extend that functionality to any project if you so choose.
Some recent examples of rain:
YAFU and DrugDiscovery@home rain
Vortac rains 10,000 GRC to celebrate a milestone
Yes it's active, it happens every now and then. Just a few days ago, the biggest solo miner (or one of) on GRC rained something like $540 worth of GRC to projects.
A pleasure as always.
It's active and is used every now and again. There are some people working on improving its functionality.
You are confusing Project Rain with rain by the sound of things. The rain implementation is complete and 100% functional.
For example, scalextrix just wrote the script you mention just below.
A must!
Hello, thanks for spending the time to publish this.
Any chance pushing GRC to other exchange like Binance?
This will definitely help to create bigger pool and publicity.
Just my opinion.
You're absolutely right that a new exchange would put GRC in front of another crypto crowd. For the moment, however, most of us are focused on building Gridcoin, the Network, and the ecosystem to do everything it can for science, math, discovery, and data analysis. If we build something amazing, the exchanges will add us without our intervention, plus people outside of cryptoland might notice us. That's where a high growth potential really sits.
