Elastos Fights Coronavirus With Elastos DMA’s Greenpass Technology – By Jeremy G.

DMA is the decentralized marketing framework in the Elastos ecosystem. They’ve come out with dApps like Choosit and Uptick for shopping, merchandising, and ticketing purposes. Recently they’ve released a prototype of a new dApp called “Greenpass.”

Greenpass is in direct relation to the Coronavirus (Covid-19) pandemic. A lot of work needs to be done to make this proof of concept dApp a working product, but it offers a unique and helpful tool for Covid-19 and other transmittable diseases.

Covid-19 began in China, spreading through the Wuhan province into the rest of the world, and this has become a worldwide public health threat. China has refined their methods of determining if an individual is allowed to pass through a quarantined area based on two factors:

1. Measure body temperature at the gate.
2. Determine whether the individual has been in an infected area in the past 14 days.

Overall, the people of China have approved and cooperated with these methods, and it has been a successful method of containment.

However, there are hurdles in the system. As a guard or administrator asks yes or no questions to each citizen, mistakes can be made through human error, and, perhaps more importantly, infection can spread just by having individuals too close to one another during the process of entering or exiting public spaces.

DMA and Greenpass created a system to give every human being in their respective country a dynamic pass that continually tracks an individual’s health under strict privacy options. This Greenpass can eventually be interoperable between different cities, states, and countries. For example, if you tested negative in the U.K., you should be free to travel to the States by presenting your credentials recorded on the blockchain.

Greenpass has 3 focuses:

Regular status checks: positive or negative.
Regular body temperature checks: value and range check.
Travel data: a personal trace of the past 14 days; have they been in certain areas?

The guard or administrator can simply check to see if these conditions are met. If safe, there will be a green pass QR Code. If not, a yellow and red pass will pop up. The guard scans the QR code on the person’s dApp and records it on the blockchain.

There’s also an appointment service feature on the dApp which allows the citizen to let a guard/administrator know in advance they will be coming to a certain location. This allows a more seamless, streamlined process, that reduces contact risk. All the data points will be connected with Elastos DID.

DMA states there will be an incentive program for all participants in order to encourage daily usage. This program is still in the works and will likely have a points model with tokens eventually being distributed. Unlike the centralized Alipay Heath QR Code, Greenpass allows its users to protect their own data and give permission for use/analysis. Alipay’s platform takes the user’s data without permission and uses it aggressively. Greenpass will formulate a fully functioning algorithm that will evolve and eventually be placed in the Leo trusted execution environment.

Brian Xin from DMA posted messages in his Telegram group about his thoughts on the project. He mentioned they are working with a medical service provider and other potential clients for a pilot case. Brian would love to hear from community members to come forward with local cases Greenpass can be utilized in. He also brought up exciting news that Greenpass will be available worldwide soon on both Android and iOS. Please join DMA’s Telegram group to enter the discussion of Greenpass and more!

Alongside DMA there are other parties helping in the efforts of developing the Greenpass dApp. LEO community team, Manhattan Project Fund, eID Vendor team, and Elastos Ecosystem team are contributing to the project on a daily basis. The team encourages all Elastos community members to reach out to public officials in their hometown to see if Greenpass can be used in their neighborhood.

Spread the word and give the green light to Greenpass, a dApp that is useful for all transmittable diseases.
