Abstract
|
Before
We will conduct a lab experiment to evaluate interventions that leverage blockchain features to promote truth-telling. The interventions are a collateral requirement (high/low), and whether the report sent by participants is randomized to flip before entering the poll.
|
After
We will conduct a lab experiment to evaluate interventions that leverage blockchain features to promote truth-telling. The interventions include 1) collateral size (high/low), and 2) transmission noise level (high/low).

Primary Outcomes (End Points)
|
Before
The truthfulness of participants' reports and whether the consensus is the same as the state of the world that participants observe.
|
After
1. Truthfulness of participants
2. Performance-dependent payoffs participants gain from the experiment

Primary Outcomes (Explanation)
|
Before
Each participant reports the state of the world. Although they have an incentive to misreport, our treatment interventions attenuate this incentive.
|
After
Two players share information about the state of the world. They have incentives to misreport, while our treatment interventions attenuate the incentives and promote truth-telling.

Experimental Design (Public)
|
Before
The experiment follows a 2-by-2 between-subjects design. Participants have an incentive to misreport in the baseline. Each treatment dimension represents an intervention to reduce the incentive to lie. By randomizing whether participants receive these interventions, we expect that lying is less frequent with the interventions than in the baseline.

Sample size (or number of clusters) by treatment arms
|
Before
50 participants low collateral no randomization (baseline); 50 participants high collateral no randomization; 50 participants low collateral randomization; 50 participants high collateral randomization.
|
After
There are 50 participants in each of the four treatments from the 2-by-2 design, so the total number of participants is 200.

Intervention (Hidden)
|
Before
1. Verifable randomness: whether the participants' vote is flipped with certain probability.
2. Size of collateral: high or low collateral.
|
After
1. Transmission noise level: high or low
2. Collateral size: high or low
