Hyperledger-powered Internet of Things applications

By Blog, Hyperledger Besu, Hyperledger Fabric

The Internet of Things (IoT) is driving an array of new distributed technology models and applications. The potential for pairing IoT and blockchain is increasingly a hot topic. This month, as part of #HypereldgerIoT, we take a look at some productions examples where the technologies are already working together. 

Read on for more about Hyperledger-powered IoT applications at work across a mix of use cases:

Norwegian Seafood Traceability Network

A recently launched Norwegian seafood traceability network leverages IBM Blockchain, which is built on Hyperledger Fabric, to share supply chain data throughout Norway’s seafood industry. The goal is to provide safer, better seafood to consumers worldwide. The network uses IoT sensors to report key environmental parameters. Starting with aquaculture, the sensors will monitor and report on the conditions required to produce high quality fish, such as water temperature, oxygen levels, and water quality, and when the fish are transported, IoT sensors will track and report factors such as the length of journey, temperature, and movement in transit. Several Norwegian seafood companies are now in the process of putting data onto the network.

My Sensor

My Sensor is an IoT device developed by Movistar that detects minute concentrations of Radon gas in the surroundings. Radon is a naturally occurring gas which may build up in your property in enclosed spaces, particularly in the basement and on lower floors. If Radon levels exceed certain thresholds, it can affect people’s health.

Leveraging Telefonica’s TrustOS MQTT module, My Sensor tracks and certifies the historical series of Radon gas concentration. The user can get a certification with full proof that guarantees the concentration did not exceed the thresholds in a period or did it during n measurements in a raw. The sensor sent the measurements through TrustOS to a Hyperledger Fabric network where some chaincodes are monitoring and certifying that the measures are in the expected range (or eventually are out of the range). The network itself certifies the series of measurements and anyone can verify it without any doubt avoiding the participation of a trusted expert third party.

VideoCoin Network

The VideoCoin Network is a decentralised video infrastructure that provides developers with video processing services that are simple to use and inexpensive compared to centralised providers. Developed by the VideoCoin Development Association Ltd. and implemented by services provider Live Planet, Inc., the VideoCoin Network runs on the Public Mint platform and is enabled by a native protocol token, the VideoCoin (VID). 

Powered by a large-scale, distributed video infrastructure, the VideoCoin Network marshals under-utilised computing resources from around the world, including IoT devices, to revolutionise enterprise-grade video services with blockchain technology. 

“Public Mint provides a revolutionary and first of its kind money system that lets us use real USD as programmable currency  allowing us to pay tens of thousands of participants on our network. This satisfies our needs to pay anyone whether they’re running a datacenter or a Raspberry Pi IoT device.” – Devadutta Ghat, CTO at LivePlanet Inc.

Backed by Hyperledger Besu distributed ledger technology, Public Mint fosters a marketplace of Smart Services that can run on top of Public Mint’s programmable fiat platform. Anyone can use the current Smart Services or build new ones, using Public Mint’s Open APIs and open-source wallet.

IoT devices integrity service

This service is an extra feature of the Hyperledger Fabric-based TrustOS product. A part of Telefonica’s TrustOS software, this library is provided to be executed by IoT devices in the secure boot. It adds as an additional HTTP header including a checksum of the secure boot for each request sent by the devices.

The first time a device sends this header, TrustOS creates an asset to track any variation in the device behaviour (including besides detecting new checksum, an IA assessing pace and frequency of the requests). Any request is registered and, if something unexpected is detected, a warning is triggered to quickly act over the affected device.

This service can’t avoid unauthorized tampering or unexpected updates but helps in identifying problems earlier and without any doubt. The result: it adds extra trustworthiness-proof beyond KPII.

Developer Showcase Series: Jim Sullivan, DC Web Makers

By Blog, Developer Showcase

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Jim Sullivan of DC Web Makers.

What advice would you offer other technologists or developers interested in getting started working on blockchain?

Blockchain is the Internet of Value as opposed to today’s Internet of Information. Building blockchain applications is no different from any other application. Regard blockchain applications as transaction applications. Blockchain applications permanently record asset transfer and asset ownership.

Give a bit of background on what you’re working on, and let us know what was it that made you want to get into blockchain?

In my work as a software engineer, I have had the opportunity to see how blockchain can rewrite rules for everyday interactions. For example, in the not too distant future, we will use blockchain to manage cellular numbers. Cellular numbers are assets, and similar to any other asset, these numbers can be modeled on a blockchain. Blockchain will allow cellular, and all phone,  numbers to be more easily and securely managed, and less subject to fraud.   

What project in Hyperledger are you working on? Any new developments to share? Can you sum up your experience with Hyperledger?

We are building an application for a cross-border secure supply chain. The Hyperledger channels provide suppliers a path for interacting with the end customer, while ensuring that their data is only visible to the end customer. The channels ensure that no supplier’s data is visible to the other suppliers.

What are the main differences between developing blockchain applications in Hyperledger or Ethereum?

While working at DC Web Makers, I often have to follow a client’s requirements especially their blockchain platform choice for development. However, I personally enjoy writing codes for both Hyperledger and Ethereum platforms. My favorite Hyperledger framework is Hyperledger Fabric and my favorite Ethereum framework and tool are Remix and the Truffle Suite. There is no doubt about it.

What do you think is most important for Hyperledger to focus on in the next year?

The most important thing Hyperledger can focus on is increasing the number of transactions per second. 

As Hyperledger’s incubated projects start maturing and hit 1.0s and beyond, what are the most interesting technologies, apps, or use cases coming out as a result from your perspective?

Hyperledger Transact is a really interesting product. We need methods for quickly creating distributed ledger technology (DLT) applications.

What’s the one issue or problem you hope blockchain can solve?

Blockchain is going to solve many problems. However, I am looking forward to seeing blockchain secure the supply chain. This will add to the quality of products and make products safer. This will enhance the quality of life for all people, everywhere. 

Where do you hope to see Hyperledger and/or blockchain in 5 years?

We hope to see robust widely accepted Hyperledger DLT applications. We need to see the number of transactions per second increase to compete against other financial systems.

What is the best piece of developer advice you’ve ever received?

Use the Scrum process, or a variation, and demo work back to the customer.

What technology could you not live without?

The Internet.
