Certain example embodiments disclosed herein relate to online survey systems and/or methods. In certain example embodiments, the questions to be asked are substantially insulated from an application that asks the questions. This abstraction may be accomplished in certain example embodiments by dynamically generating a computer-accessible (e.g., web-based) survey from one or more definition files. For example, a survey may be defined via a response definition file and a user interface definition file, thereby enabling the definition files to be read and the survey to be presented with the appropriate questions, validations, and transformations being specified by the response definition file, and with the look and feel being specified by the user interface definition file. Answers to questions may be persisted for a respondent in a storage location remote from the respondent. Such online surveys systems and/or methods may be suitable for census-related activities.

Blockchain-based, smart contract platforms have great promise to remove trust and add transparency to distributed applications. However, this benefit often comes at the cost of greatly reduced privacy. Techniques for implementing a privacy-preserving smart contract is described. The system can keep accounts private while not losing functionality and with only a limited performance overhead. This is achieved by building a confidential and anonymous token on top of a cryptocurrency. Multiple complex applications can also be built using the smart contract system.
