    How Cryptocurrency Discussions Spread

    Data scientists at Pacific Northwest National Laboratory examine the speed and scale of cryptocurrency discussion spread

      PNNL data scientist, Dr. Svitlana Volkova and her team analyzed three years of discussions on Reddit from January 2015 to January 2018.

    RICHLAND, WASHINGTON, June 10, 2019 – A rapidly increasing percentage of the world’s population is connected to the global information environment.  At the same time, the information environment is enabling social interactions that are radically changing how and at what rate information spreads. As part of an effort to understand communication patterns and build a quantitative framework for how this information expands online, researchers at Pacific Northwest National Laboratory, a United States Department of Energy national laboratory, recently examined cryptocurrency discussion threads on Reddit. Their findings, presented at the Web Conference 2019, not only shed light on how cryptocurrency discussions spread but could inform artificial intelligence applications for modeling information spread across internet social environments to help identify and model criminal activities by state and non-state actors exploiting cryptocurrencies.

    Every day, thousands of messages on Reddit [and elsewhere] contain discussions of cryptocurrencies.  Some of these trigger follow-up discussions.  Some lead to increased interest in a cryptocurrency -- not just a discussion of that cryptocurrency, but its actual price/value.  Clearly, not all cryptocurrencies are equivalent -- and analyzing a set of them can reveal how bad actors might exploit those differences.

    Led by PNNL data scientist, Dr. Svitlana Volkova, the team analyzed three years of discussions on Reddit from January 2015 to January 2018. The team measured the speed and scale of discussion spread related to Bitcoin, Ethereum, and Monero cryptocurrencies. Findings include:

    • On average, there are 3,600 comments posted each day for Bitcoin; 500 for Ethereum; and 380 for Monero.
    • Not every post triggered a discussion. The rate of ineffective posts—posts that do not receive any additional commentary—is up to 5x higher with Bitcoin and Ethereum than Monero.
    • People respond quicker to Bitcoin posts. For example, it takes on average 11 minutes for someone within the Bitcoin subreddit to comment; 20 minutes for Monero; and 27 minutes for Ethereum.
    • Bitcoin discussions grow the fastest, followed by Ethereum and then Monero.
    • Discussions around Monero have largest median lifetimes. Ethereum discussions have the largest possible lifetimes, and, Bitcoin discussions have the lowest median lifetime of the three coins.

    “Cryptocurrencies are quite unique observable units of information in the way discussions about them spread across social platforms,” said Volkova. “These social signals are quite useful, and by incorporating them with machine and deep learning, we intend to build predictive models that hit on causal relationships between different variables so we can explain model decision-making processes.”

    The findings gathered by Volkova and her colleagues, PNNL researchers Maria Glenski and Emily Saldanha, provide valuable insights into how information expands and evolves in social platforms. Likewise, by focusing on a specific social phenomenon, the team hopes to compare the spread of cryptocurrency discussions with other viral trends, such as the spread of computer vulnerabilities and misinformation.

    Additional information on the team’s findings can be read at: https://dl.acm.org/citation.cfm?id=3313702. The work was funded by the Defense Advanced Research Projects Agency.

    A sharper focus: New computational technique resolves compressed X-ray data

    With high-energy X-rays, such as those that will be produced by the upgrade to Argonne's Advanced Photon Source comes a potential hitch -- the more penetrating the X-rays are, the higher a likelihood that researchers could run into problems with the image data. In a new study, researchers at Argonne have found a novel way to combat this image degradation.

    Light dark matter is a thousand times less likely to bump into regular matter than previous astrophysical analyses allowed

    A team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University has narrowed down how strongly dark matter particles might interact with normal matter. Based on the number and distribution of small satellite galaxies seen orbiting our Milky Way, the team found this interaction to be at least a thousand times weaker than the strongest interaction allowed by previous astrophysical analyses.

    New Sensor Could Shake Up Earthquake Response Efforts

    An optical sensor developed at Berkeley Lab could speed up the time it takes to evaluate whether buildings are safe to occupy after a major earthquake. After four years of extensive peer-reviewed research and simulative testing at the University of Nevada's Earthquake Engineering Laboratory, the Discrete Diode Position Sensor (DDPS) will be deployed for the first time this summer in a multi-story building at Berkeley Lab - which sits adjacent to the Hayward Fault, considered one of the most dangerous faults in the United States.

    Designer proteins form wires and lattices on mineral surface

    This research is a fundamental discovery of how to engineer proteins onto non-biological surfaces. Artificial proteins engineered from scratch have been assembled into nanorod arrays, designer filaments and honeycomb lattices on the surface of mica, demonstrating control over the way proteins interact with surfaces to form complex structures previously seen only in natural protein systems. The study provides a foundation for understanding how protein-crystal interactions can be systematically programmed and sets the stage for designing novel protein-inorganic hybrid materials.

    Giving nanowires a DNA-like twist

    Argonne National Laboratory played a critical role in the discovery of a DNA-like twisted crystal structure created with a germanium sulfide nanowire, also known as a "van der Waals material." Researchers can tailor these nanowires in many different ways -- twist periods from two to twenty micrometers, lengths up to hundreds of micrometers, and radial dimensions from several hundred nanometers to about ten micrometers. By this means, they can adjust the electrical and optical properties to optimize performance for different applications.

    Bursts of Light Shape Walls Between Waves of Charge

    Bursts of Light Shape Walls Between Waves of Charge

    To better store data, scientists need ways to change a material's properties suddenly. For example, they want a material that can go from insulator to conductor and back again. Now, they devised a surprisingly simple way of flipping a material from one state into another, and back again, with flashes of light. A single light pulse turns thin sheets of tantalum disulfide from its original (alpha) state into a mixture of alpha and beta states. Domain walls separate the two states. A second pulse of light dissolves the walls, and the material returns to its original state.

    Deep Learning Reveals Mysteries of Deep Space

    How do you determine the measurable "things" that describe the nature of our universe? To answer that question, researchers used CosmoFlow, a deep learning technique, running on a National Energy Research Scientific Computing Center supercomputer. They analyzed large, complex data sets from 3-D simulations of the distribution of matter to answer that question. The team showed that CosmoFlow offers a new platform to gain a deeper understanding of the universe.
