Walmart, IBM Are Planning to Launch the First Blockchain-based Food Safety Solution

  • Blockchain-based systems to manage supply chains may help prevent infected food sources from being sold to consumers.
  • IBM and Walmart are working to launch a blockchain-powered supply chain management system.

US-based Walmart Inc., one of the world’s largest retail corporations, has reportedly been developing a blockchain-based food safety program through a collaboration with IBM. Walmart will require all of its outlets that supply leafy green vegetables to record their sales information on its proprietary blockchain-enabled solution by September 2019.

The existing supply chain management system requires many time-consuming manual processes to be completed before orders can be processed. There are also many intermediaries, or third-parties, that are involved in managing the current supply chain network.

Because of these operational inefficiencies which don’t allow items to be tracked effectively, there have been many serious problems like the E. coli romaine outbreak. Although most Escherichia coli bacterium are not harmful, this particular strand was responsible for five deaths and 200 people were hospitalized after being infected.

Food Supply Management On A Blockchain

Proponents of blockchain technology think that lettuce or any other item being transported on a supply chain can be more traceable and the transactions involved can be more transparent if registered on the distributed ledger.

A blockchain-powered model that aims to ensure food safety in the supply chain process could require each entity that handles food directly to be assigned to a node. With this approach, a network of nodes consisting of all food handlers may be managed on a blockchain.

This type of digital supply chain model may potentially make it easier and a lot quicker to check if infected food items have been sold before causing serious damage.

Blockchain-Powered Food Safety System

Walmart and IBM have been working on developing blockchain-based supply chain management software for the past 12 months. Many distributed ledger technology (DLT) experts think that digitizing legacy supply chains is one of the best use cases for the technology.

IBM’s proprietary blockchain-enabled Food Trust solution aims to “create a food ecosystem built on trust and transparency.” Commenting on the food safety initiative, Bridget van Kralingen, the senior vice president for IBM’s Global Industries and Blockchain, said:

We built the IBM Food Trust solution using IBM Blockchain Platform, which is a tool or capability that IBM has built to help companies build, govern and run blockchain networks.

Kralingen added that the IBM Blockchain platform was built by using Hyperledger Fabric. As described on its official website, Hyperledger Fabric is a DLT-based “smart contract engine” supported by the open-source Linux Foundation. It reportedly allows consensus (on a blockchain) and various other “membership services” to be plug-and-play (PnP).

Tracking Infected Food Sources In Seconds

Migrating the food tracking process to a blockchain-based supply chain can reduce the time required to identify the food source from 7 days to 2.2 seconds, according to Walmart. Clearly, this would allow companies to track infected food before it is sold to the consumer.

One potential challenge with a blockchain solution might be that people might not know how to manage data using the new technology. However, Walmart representative Molly Blakeman said that the only thing users will be required to do is upload data to their blockchain network.

Blakeman explained:

IBM will offer an onboarding system that orients users with the service easily. Think about when you get a new iPhone ... the instructions are easy to understand and you’re quickly up and running. That’s the aim here. Essentially, suppliers will need a smart device and internet to participate.

Bitcoin Ransomware Attackers Threaten to Publicly Shame Victims Who Won’t Pay Up

  • Bitcoin ransomware attackers are using public shaming to pressure their victims into paying up.
  • At least one public website lists companies affected by attacks that refused to pay the ransom. 

Bitcoin ransomware attackers are reportedly publicly shaming and threatening to expose victims who won’t pay the ransom price. 

According to a report by KrebsOnSecurity, at least one popular crypto ransomware group has created a public website identifying companies that chose to rebuild their web operation following an attack, rather than paying the ransom. 

The report identified the public shamers as the group behind the Maze Ransomware, which was responsible for the Pensacola web attack last week which asked for a $1 million in bitcoin ransom. Cybersecurity experts advise against paying any ransom, as there's no guarantee the attackers will decrypt victims' files after the payment has been sent.

As CryptoGlobe recently reported, there are even cases of cryptocurrency ransomware extortionists losing control of their own decryption tools.

The website, which is publicly available, provides information on the date of the attack, the nature of the files stolen and the IP addresses of those affected. The site also tells visitors to “wait for their databases and private papers here.” KrebsOnSecurity claims that at least one company gave in to the pressure of the public shaming and paid the ransom in order to avoid being out on the website. 

Crypto-based ransomware attacks have been on the rise in 2019. Just last weekend, the city of New Orleans was forced to declare a state of emergency and shut down its computers following an attack.
