Social Proof00:52

Social Proof

32.4K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Energy Associated With a Charge Distribution01:21

Energy Associated With a Charge Distribution

1.9K
The work done to bring a charge through a distance r is given by the potential difference between the initial and the final position. To assemble a collection of point charges, the total work done can be expressed in terms of the product of each pair of charges divided by their separation distance, defined with respect to a suitable origin. Solving this expression gives the energy stored in a point charge distribution.

Conservation of Energy in Control Volume01:14

Conservation of Energy in Control Volume

1.1K
Consider a turbine operating under steady-flow conditions. The control volume is drawn around the turbine, with fluid entering at one point and exiting at another. The turbine extracts energy from the fluid, which performs mechanical work (shaft work).
For steady flow systems, the time derivative of the stored energy becomes zero since there is no energy accumulation within the control volume. This simplifies the energy equation to:

What is Energy?04:10

What is Energy?

59.1K
The universe is composed of matter in different forms, and all forms of matter contain energy.  The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free Energy01:21

Free Energy

52.1K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

The Energies of Atomic Orbitals03:21

The Energies of Atomic Orbitals

30.2K
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.

Area of Science:

  • Computer Science
  • Cryptography
  • Distributed Systems

Background:

  • Proof of Work (PoW) is a foundational consensus mechanism in cryptocurrencies like Bitcoin and Ethereum.
  • High energy consumption during PoW mining is a significant environmental concern and a perceived weakness.
  • Existing PoW systems face scalability and efficiency challenges.

Purpose of the Study:

  • To adapt the Proof of Work (PoW) consensus mechanism to mitigate its perceived weaknesses, particularly high energy consumption.
  • To develop a configurable system that restricts PoW puzzle solving to a dynamic set of nodes based on the blockchain's state.
  • To enhance blockchain resilience and potentially foster more democratic public networks.

Main Methods:

  • Introduction of Proof of Kernel Work (PoKW) to dynamically reduce the set of participating nodes in PoW puzzles.
  • Leveraging Practical Adaptation of Existing Technology (PAET) for implementation using current blockchain and enterprise stacks.
  • Application of Machine Learning for Adaptive System Resiliency (ML-ASR) to adapt to dynamic system, network, and attack conditions.

Main Results:

  • Detailed development of the Proof of Kernel Work (PoKW) mechanism, focusing on its theoretical underpinnings and security.
  • Illustration of the Practical Adaptation of Existing Technology (PAET) through a pilot project with Porsche for access control.
  • Analysis of potential attack vectors for PoKW consensus and proposed mitigation strategies.

Conclusions:

  • The proposed PoKW consensus mechanism offers a promising approach to reduce energy consumption in PoW systems.
  • The integration of ML-ASR and PAET demonstrates the feasibility and adaptability of the PoKW approach.
  • PoKW has the potential to create more resilient and democratic blockchain systems for public networks.
