The Third IEEE International Workshop on Blockchain and Mobile Applications (BlockApp 2021)
November 1, 2021 – Dallas, Texas, USA Virtual Event

BlockApp 2021 will have a joint program with CPS-Sec 2021.

In conjunction with the 29th IEEE International Conference on Network Protocols (ICNP 2021), November 1-5, 2021


Blockchain has already shown its great success in serving as the fundamental technique behind many cryptocurrencies. Its promising capability of decentralized consensus also attracts a wide realm of real-world applications such as international banking, electronic voting, supply-chain management, media communications, and food safety traceability. Meanwhile, with the advancement of 4G/5G mobile communication techniques, more and more data are being generated by mobile phones, wireless sensors, and IoT devices. Mobile decentralized applications (DApps) usually involve many untrusted parties. How to use blockchain to build trust, reduce the operational cost, and accelerate mobile transactions brings many new open issues and challenges for both research communities and industry.

The International Workshop on Blockchain and Mobile Applications is an international forum that aims to bring together researchers and industry practitioners to foster the advancement of blockchain technique and its applications in mobile environments. The workshop solicits original research contributions or novel blockchain applications and experiments. Topics of interest include but not limited to:

  • Benchmarking of blockchain systems
  • Blockchain protocol design
  • Blockchain and 5G mobile networks
  • Blockchain and artificial intelligence
  • Blockchain and big data
  • Blockchain and distributed storage
  • Blockchain and edge computing
