Blockchain-enabled applications developer Acoer has created a data visualization tool to track the deadly coronavirus. The tool, known as the HashLog data visualization engine, interacts in real-time with Hedera Hashgraph’s distributed ledger technology. This allows researchers, scientists and journalists to understand the spread of the coronavirus and its trends over time through visuals presented on Acoer’s HashLog dashboard.
Acoer’s CEO, Jim Nasr, told CryptoX that the HashLog tool pulls data from the Center for Disease Control and the World Health Organization to capture useful information regarding the virus. He said:
“HashLog allows for the real-time visualization of coronavirus data and trends. This includes the overall number of cases globally, rates of deaths and recovery per infections (where we have reliable data), cases filtered by country, as well as Google trends by interest and region on coronavirus.”
While Nasr was unable to mention specific organizations and names, he said that HashLog has drawn interest from public health officials at federal and state levels in the United States, along with journalists from blockchain and health care outlets. He also noted that there have been a few international inquiries requesting to use the tool.
Although HashLog may sound similar to other coronavirus real-time tracking tools, like the map created by Johns Hopkins University’s Center for Systems Science and Engineering, Nasr explained that its dashboard is more advanced than most solutions, saying that the data is not easy to visualize or extract:
“With HashLog, our objective is to make data collection automated. The tool provides researchers with dynamic dashboards that change as criteria is filtered in any one widget/dashboard component. It also lets users directly download filtered data from the visualizations.”
Interestingly, both the data tracking map created by Johns Hopkins University and HashLog show the specific regions where the coronavirus has been reported. The Center for Disease Control map only shows the virus reported per country. However, the CDC also offers more in-depth information regarding the virus, such as reports of cases in the U.S., along with information for travelers and health professionals.
A single source of truth to track the coronavirus
HashLog works by interacting in real-time with Hedera Hashgraph’s distributed ledger technology, which is a database that is consensually shared and synchronized across multiple sites, organizations or regions helping to track the virus more efficiently.
It’s important to note that while blockchain is a type of distributed ledger, Hedera Hashgraph’s white paper explains that the company’s technology incorporates every transaction into its ledger. This should make Hedera’s technology more efficient than typical blockchain-based solutions, as it can, for example, serve as a master database that is capable of receiving multiple updates in near real-time.
Hedera Hashgraph’s CEO, Mance Harmon, told CryptoX that health care and public health information is a key area where distributed ledger technologies can provide computational trust, serving as a source of truth for multiple parties. He said:
“Hedera’s distributed ledger technology ensures that information cannot be manipulated or changed without the world seeing it. Acoer’s Hashlog takes advantage of Hedera as the trust layer of the internet to allow users to be confident in the real-time information they receive related to the coronavirus.”
Mance further explained that this use case utilizes Hedera’s mirror node functionality, letting any user who wants to view the ledger tracking the coronavirus to run a mirror node. He explained:
“The way to think about mirror nodes is to store the transaction history from the mainnet. The mainnet nodes are run by our council members. These nodes process transactions, putting them into a consensus order-stream. This information streams to all the mirror nodes in the world, letting anyone who wants to see and analyze the data from the mainnet.”
According to Mance, mirror nodes are capable of scaling infinitely, tracking anything from health care to financial information as a source of truth.
Blockchain’s role to support coronavirus victims
Blockchain technology is also being used to support the thousands of coronavirus victims. On Feb. 4, Hyperchain launched a blockchain-based platform that is being used to track medical supply donations sent to hospitals in central China.
Hyperchain’s platform uses blockchain to ensure that donations are traceable and immutable, providing donors with transparency to see exactly where their donations are going to fight against the coronavirus.
