In recent years, the humanitarian and development sectors have increasingly relied on digital surveys to collect data for decision-making purposes. However, traditional survey methods can be plagued with problems such as lack of data security, reliability, and transparency. This is where blockchain technology can offer a solution.

Blockchain has the potential to transform the way digital surveys are conducted in the humanitarian and development sectors.

There are three main features of blockchain use in surveys:

• Immutability of data
• Incentivizing participation
• Privacy of user information.

Once data is stored on a blockchain, it cannot be altered or deleted. This ensures that survey data is tamper-proof and that the integrity of the data is maintained. This is particularly important in the humanitarian and development sectors where accurate and reliable data is critical for decision-making.

Another feature of blockchain technology is the ability to incentivize participation. Blockchain can be used to create smart contracts that reward survey participants for completing surveys. These rewards can be in the form of tokens or cryptocurrency. This incentivization can increase participation rates and ensure that surveys are completed in a timely and efficient manner.

Lastly, privacy of user information is of utmost importance when conducting surveys, especially in the humanitarian and development sectors. Blockchain technology can help to ensure the privacy of user information by using encryption techniques to protect user data. Users can have control over their data and can choose what information they want to share with survey organizers. This can help to build trust between survey organizers and participants.

The use of blockchain technology in digital surveys has the potential to revolutionize the way surveys are conducted. Blockchain can provide a more secure, reliable, and transparent platform for collecting survey data. As this technology continues to evolve, we can expect to see even more innovative use cases for blockchain in the survey space.
