Essentially, it would then become a fully trusted survey system (once the review would be on the chain there would be no way anyone could change it), which will be a main requirement for bluechips clients when they become more knowledgeable around this subject.
Which wouldn't involve any change in LimeSurvey cause you wouldn't place data during an active survey on a blockchain. Placing a review on a blockchain would be done after a survey is closed.
Reasons for not interacting with any blockchain during a survey are e.g. speed and amount of interactions in a short time.
Reasons for not placing surveydata in a blockchain is the privacy and the right of respondents to revoke personal data.
If you need to ensure that exported data of a survey stays unmodified after a certain point of time, you can do that in more simple way.
Depending on who needs to see and validate the proof, you can publish a hash-code of the dataexport on twitter or sign the file with a digital time stamp
(
en.wikipedia.org/wiki/Time_stamp_protocol
).
In all cases there are authorities involved you need to trust to a certain point. E.g. if I post a hash-code on twitter, I hope that nobody from Twitter will change my post. Other could see the change and Twitter would be in Trouble if they change posts from their users. When I use a SSL cert of Let's Encrypt I trust them, that they won't generate a second certificate for my domain to others.
Conducting a survey will require trust to third party. The question is where can the use of a "survey blockchain" reduce the people/organizations you need to trust to prove that the survey data wasn't manipulated. My first question would be, who will be responsible to define, code and maintain the infrastructure for the survey blockchain service? The weakest point in using a blockchain is the software client. Wouldn't a bluechip company wants to know who has released software they should use and perhaps install on there computers?

This is the SHA3-512 hashcode for the last paragraph.
en.wikipedia.org/wiki/SHA-3
Placing that on social media and mailing that to people will ensure that anyone can check if the text has changed and that I can always prove what my text was.
You need to trust the SHA3 algorithm, the software, which allows you to use SHA-3 and the public websites you place the hashcode.
