The Juri protocol

The Juri protocol is designed for applications that want to provide their users with incentives for maintaining healthy behaviours, where compliance with those behaviours can be computationally verified.

Exercising at an elevated heart rate, attending a yoga class, and getting seven hours of sleep are all the type of activities that can be verified as having taken place.

Juri enables incentives by facilitating ‘staking pools’, whereby members of a group are able to bet that they will comply with healthy behaviours. Those who comply with the goal receive rewards, while those who do not lose out.

Smart contracts on the blockchain act as the funds custodian and agreements ledger during the staking period, while a series of open source libraries running on Juri network nodes perform the verification of activities.

The protocol runs on top of Ethereum, an open-source, public, blockchain-based distributed computing platform and operating system.

Example of an app using the Juri Protocol


Max joins or is part of a health-centric community.

Step 1
Step 2

The community offers the chance to opt-in to an app offering financial incentives to meet your wellness goals. Max sees this as an opportunity to invest in and motivate herself on her health journey.


She stakes an amount she’d hate to lose.

Step 3
Step 4

She then works out during the week. She’ll have a heart rate monitor on. As Max works out, the app is sending her HR data to a bunch of computers.


Each computer belongs to a ‘Juri Miner’ who is validating the data and updating the Juri network with information about her degree of success with regards to the goal/standard. At the end of a week, all of the nodes/miners agree on what should be in the ledger, and Max’s reward.

Step 5
Step 6

Scenario 1

After completing what she backs herself to do, she gets all her money back, plus 5% as a reward.

Scenario 2

Unfortunately, failing to meet her exercise commitments means she forfeits some of the money she’d put up.
