The Reality of Sampling on the Blockchain
I’m John
Sampling on the blockchain
1. An overview (very high level)2. An example (very low level)
How does cryptography help us do better market research?

Researcher Respondent
Researcher creates a sample request including demographic targeting, survey URL, and deposits sufficient funds
Respondent’s device monitors the blockchain, sees the new request, checks to see if the respondent qualifies, and if so indicates interest
2
Blockchain runs sampling algorithm and renders an offer to the respondent
3
Respondent answers a survey via external survey engine

12,062 Respondent 1 Asserts qualification, registers interest
12,101 Blockchain Issues offer to Respondent 1
12,117 Respondent 1 Accepts offer
12,904 Confirmit Registers complete for Respondent 1
12,904 Blockchain Deducts funds from Researcher A and pays Respondent 1

The problem:How do we sample without a
respondent database?

Cryptographic voting schemes allow voters to keep their vote private but be
satisfied that it was counted

Why should we care?
1. If it’s possible to do our job without managing a big database of sensitive user data, then we should

2. It’s a means to enable sampling on the blockchain which unlocks many other benefits
