Survey Safety01:28

Survey Safety

60
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Ethical Standards I01:25

Ethical Standards I

867
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

Ethical standards are the backbone of nursing practice, guiding nurses as they interact with patients, families, and colleagues. These standards are crucial for providing safe, empathetic care centered on the patient's needs.
Nurses are entrusted with upholding various ethical principles and standards. Nurses forge solid therapeutic relationships using trust, empathy, autonomy, confidentiality, and professional competence.
Confidentiality is crucial, embodying respect for individual privacy...

Electron Behavior00:54

Electron Behavior

Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...

Area of Science:

  • Blockchain Technology
  • Smart Contract Security
  • Cybersecurity

Background:

  • Existing tools for detecting unsafe smart contracts lack practical application for users and owners.
  • Disseminating security vulnerability information for smart contracts is challenging.

Purpose of the Study:

  • To present a novel platform, Blockchain Safe Browsing (BSB), for the secure dissemination of smart contract vulnerability detection results.
  • To enhance the practical benefit of security analyses for both smart contract users and owners.

Main Methods:

  • Development of a Blockchain Safe Browsing (BSB) platform.
  • Generation of an encrypted blacklist for privacy-preserving user warnings.
  • Implementation of a system to notify contract owners of vulnerabilities and offer exploit reports.
  • Design of an effective encryption scheme for secure report access.

Main Results:

  • The BSB platform effectively disseminates detection results, offering privacy-preserving warnings to users.
  • Contract owners can access detailed vulnerability reports, incentivizing ongoing research and updates.
  • The encryption scheme ensures only authorized contract owners can decrypt sensitive vulnerability information.
  • Evaluations confirm the prototype's functionality and positive user experience.

Conclusions:

  • The Blockchain Safe Browsing (BSB) platform provides a viable solution for practical application of smart contract security findings.
  • The system incentivizes continuous improvement in smart contract security by rewarding researchers.
  • BSB enhances user safety and empowers contract owners to address vulnerabilities effectively.
