Exercise Supplement

The "Exercise Supplement," based on the theory of Behavioral Economics, has been released, providing motivation for you, your family, and friends to start and maintain a walking routine!


The technology of the "Exercise Supplement," which promotes the transformation of human behavior, has been patented (Patent No. P6696672).

Walking daily is essential for good health, but starting and continuing a walking routine can be challenging.


● What is the Exercise Supplement?
In the "Exercise Supplement," for example, you create a walking challenge such as walking more than 8,000 steps/day for 30 days and deposit JPY 2,000 worth of cryptocurrency or tokens onto the blockchain. When the challenge is successful, the deposit is returned to you; if unsuccessful, the deposit is paid to your friend (2% of the operator fee is deducted from the deposit. Additionally, a blockchain fee called GAS is incurred).
You'll work hard to avoid losing the deposited JPY 2,000 worth of cryptocurrency or tokens.
In the app, you can freely set the challenge participant, deposit amount, payee upon success or failure, and the distribution for each.
The app uses step count data from the iOS healthcare app (HealthKit) to send to the blockchain during the challenge.


● Technologies of the "Exercise Supplement"
The app utilizes smart contracts on the Blockchain such as Astar, Polygon.
For example, users can create the following challenge using the app:
- Challenge period is from May 10, 2021, to June 10, 2021
- Walk more than 8,000 steps daily during the challenge period
- Deposit tokens worth JPY 2,000
- Upon successful challenge completion, deposit is distributed to Mr. A
- If the challenge fails, the deposit is distributed to Mr. B
The challenge content is included in a smart contract on the blockchain.
Users can send step data to smart contracts using the app.
The smart contract determines the challenge's success or failure based on step data and distributes the deposit accordingly.
The "Exercise Supplement" technology, which promotes the transformation of human behavior and is based on Behavioral Economics, has been patented (Patent No. P6696672).
