Hot Research Topics for Security and Privacy in Blockchain Technology

   Security and privacy are two significant challenges in blockchain-based systems. Blockchain technology has some fundamental security properties from implementing cryptography and bitcoin solutions. Blockchain technology satisfies the security requirements like availability, integrity, consistency, pseudonymity, anonymity, and double-spending prevention. However, the breakthroughs in blockchain systems motivate the miners and investors to develop various financial and non-financial application services. The security requirements of diverse applications are also different. Hence, satisfying the application-specific security and privacy needs is crucial in accomplishing a successful blockchain deployment. The additional security requirements that need to be developed for blockchain technology are as follows.
  • Unlinkability
  • Confidentiality of Transactions
  • Data Privacy

Some Security and Privacy Methods Designed for Blockchain:

  • Mixing
