Preface
The 26th International Conference on Financial Cryptography and Data Security (FC
2022) was held on the beautiful island of Grenada from May 2 to May 6, 2022.
The conference is organized annually by the International Financial Cryptography
Association (IFCA) and is a major international forum for research, advanced
development, education, exploration, and debate regarding information assurance,
with a specific focus on financial and commercial contexts. The conference aims to
attractworksfocusingonbothfundamentalandreal-worlddeploymentsonallaspects
