Once Again, Forbes “Blockchain 50” Shows Enterprise Blockchain’s Footprint and Impact, with Hyperledger Technologies Leading The Pack

By Hyperledger Blog, Hyperledger Aries, Hyperledger Fabric, Hyperledger Grid, Hyperledger Indy, Hyperledger Sawtooth

Declaring that blockchain has “gone mainstream,” Forbes today released its 2021 “Blockchain 50,” featuring companies that have at least $1 billion in revenues or are valued at $1 billion or more and “lead in employing distributed ledger technology.” And, once again, half of the companies on the list are using Hyperledger technology. 

Twenty five companies on the list name at least one Hyperledger technology as part of their solution platform. Hyperledger Fabric, specifically, is cited as a platform by 24 of the companies, topping the list as the most widely used technology. Hyperledger Aries, Indy, Grid and Sawtooth are all also deployed by companies on this list. 

The annual list, now in its third year, reflects the growing global impact of blockchain technology with 25 members from the U.S., 13 from Europe and a record 12 from Africa, Asia, the Middle East and Latin America. All in all, there were 21 companies that were new to the list, and 15 of them, including ones from Australia (BHP), India (Tech Mahindra) and Africa (Sappi), use Hyperledger-based platforms. 

Of the 12 companies that have made the list every year, six (Ant Group, Cargill, DTCC, IBM, ING and Walmart) use Hyperledger technologies.

More than just a basic list of companies and technologies, the Forbes Blockchain 50 provides a snapshot of the market-changing deployments these blockchain leaders have deployed. Accompanying stories add even more analysis and context. 

This annual look at the market is a good reflection point for the traction our technologies have in the current market but also a guidepost to what needs to come next. The increasing global adoption of blockchain – public, private, hybrid – and coming shifts in currency adoption and payments as well as uptake in markets as diverse as mining, telecom, pharma and shipping all point to the growing reach of distributed ledger technology. And, in the face of such challenges as the pandemic, climate change and income equality, it is important to put the focus on what we can accomplish building on blockchain as a cornerstone.

Interoperability and Integration Developments in the Hyperledger Community

By Hyperledger Blog, Hyperledger Aries, Hyperledger Besu, Hyperledger Cactus, Hyperledger Fabric, Hyperledger Grid, Hyperledger Indy, Hyperledger Sawtooth

Interoperability and integration are top of mind issues across the blockchain space right now. From new projects to new solutions, the Hyperledger community is taking on the challenges of cross-chain and cross application communication and data flow. 

Here are some of the most recent #HyperledgerInterop developments from across the community.

New Project – Hyperledger Cactus

The newly announced Hyperledger Cactus is a blockchain integration tool designed to allow users to securely integrate different blockchains. This pluggable architecture helps enable the execution of ledger operations across multiple blockchain ledgers, including Hyperledger Besu, Hyperledger Fabric, Corda, and Quorum available today, with the aim of developers continually adding support for new blockchains in the future. 

 Cactus started as a Hyperledger Labs project six months ago and has attracted significant attention and become a locus of collaboration between developers from teams at Accenture and Fujitsu, and dozens of others working on DLT platforms both inside and outside Hyperledger.

Member applications

  • DAML, the open source smart contract language created by Digital Asset, enables application portability across three major Hyperledger frameworks: Besu, Fabric and Sawtooth. Blockchain Technology Partner’s Sextant for DAML supports both Hyperledger Besu and Sawtooth, as well as Amazon QLDB and Aurora cloud databases, allowing the same distributed application to be easily deployed across all four platforms. Hear more about the “Write Once, Interoperate Anywhere” approach in this presentation on how DAML smart contracts connect networks, especially Hyperledger Besu, Fabric and Sawtooth.
  • Hyperchain Labs created an oil and gas ticketing blockchain network to help companies reduce costs, improve performance and maintain compliance. The network is built using the Hyperledger Fabric framework and is run on the IBM Blockchain Platform. BlocWatch software is used to ensure the Hyperchain Labs network is running optimally and securely. As a monitoring and security tool, BlocWatch seamlessly integrates with Hyperchain Labs and IBM, empowering users to easily manage all platforms in one place. Explore how Hyperchain Labs uses BlocWatch in conjunction with the IBM Blockchain Platform in this short video.
  • Smart Block Laboratory built the Hyperledger Fabric-powered distributed register Cryptoenter, blockchain infrastructure for digital banking that unites banks into a single digital space for transmitting financial messages and brings a new level of interaction to the financial market. The platform is designed for p2p interaction between consumers of financial services, safe execution of payment transactions with cryptocurrencies, fiat currencies and cryptocurrencies, user interaction within a social network for investors / distributed crowdfunding platform.

    The basis of the platform is the Rubicon Blockchain, a cloud platform for the blockchain economy, built on Hyperledger Fabric. Cryptoenter has a dual security system: at the Hyperledger blockchain network level and at the Rubicon Blockchain (also based on Hyperledger Fabric) network level. The solution uses an SRP authentication system. TLS (transport layer security) protocol based on SSL (Secure Sockets Layer) protocol is also included. This dual security system allows Cryptoenter to authenticate the person who signed the message, control message integrity, protect the message from fakes and prove the authorship of the person who signed the message.

Technical talks from Hyperledger Global Forum

Nathan George from the Sovrin Foundation offers his take on “Standards and Interoperability for Identity”

 Identity platforms have made significant advances leveraging blockchain technology and standards developed at Hyperledger. In his talk, Nathan covers the latest in trusted information flows and the standards being incubated to promote interoperability and create network effects across multiple blockchains and identity platforms.

Key topics include the advancements incubated in Hyperledger Indy, Hyperledger Aries, the W3C Credentials Community Group and at the Decentralized Identity Foundation for Verifiable Credentials, Decentralized Identifiers (DIDs), DID Communications, Identity Hubs, Authentication, and the data models that power them.

Panelists Rich Meszaros and Sarah Banks from Accenture, Melanie Nuce from GS1 US, David Cecchi for Cargill and Patrick Erichsen from Target discuss “Business Interoperability – The Key to Supply Chain Traceability”

Technology such as blockchain has the power to solve complex challenges and achieve improved supply chain traceability. In order to tap into this powerful technology, interoperability, enabled by robust data and transaction standards, are a must! Segments of the supply chain, such as the food industry, have made significant progress leveraging data standards to support food safety and product transparency use cases. The panelists discuss their companies’ work on improved supply chain traceability, the importance of standards and the role business interoperability plays in accelerating the success of new technologies like blockchain.

Hyperledger Grid and GS1 Standards: Harmonizing Static and Dynamic Data

By By Melanie Nuce, Senior Vice President, Corporate Development, GS1 US Blog, Hyperledger Grid

Supply chain professionals are all too familiar with the persistent challenges that plague the industry–a lack of inventory visibility, not having complete or trustworthy data to share with partners, or not enough business process consistency are a few issues that come to mind. However, somewhat ironically, it often takes industries joining together to collaborate to solve these issues that ultimately helps companies enjoy longevity and stand out from their competition.

It’s this “collaborate to compete” concept that has inspired so much discussion around what blockchain can do to help improve the supply chain. With a long history of facilitating collaboration to adopt new technologies and business processes, GS1 US has applied this open community spirit to our work on Hyperledger Grid, a collaboration with Cargill, Target, Intel and Bitwise IO. This project builds on Target’s earlier proof of concept based on the open source solution ConsenSource that was focused on certifying suppliers for its private label paper products. Experiencing success in this test, the retailer branched out to explore how Hyperledger Grid could be applied for better food traceability with supplier, Cargill.

For the past several months, the Hyperledger Grid team has investigated the role of GS1 Standards in blockchain development. We’ve discussed how to help create the ideal foundation for supply chain-based blockchain applications to flourish. The partners understand the need to standardize static data, such as a product’s Global Trade Item Number (GTIN) and core attributes, as well as more dynamic details like time, location and temperature readings that are important for transaction-based communications, such as procurement and track and trace. 

All of this is reflective of this overall nascent stage of blockchain’s life cycle where supply chain partners are still agreeing on what is “the right data” to share on a blockchain. Regardless of how they are piloting blockchain, many companies are finding that this is the time to say “enough is enough” and end the churning of poor data quality that has particularly plagued supply chain for many years. 

Several GS1 Standards provide consistency and structure to data transactions on a blockchain, increasing the likelihood that the intended outcome will be achieved: 

GTIN – This product identifier plays a critical role in global commerce, as it helps businesses manage items on both the physical and digital shelf. Unique like your own fingerprint, a GTIN is composed of numbers that identify the company making a product and numbers that identify the product. If every item is uniquely identified with its own GTIN, it retains an identity regardless of where it is in the supply chain. 

This number is what is encoded into a UPC and scanned at checkout, but is mightier than this function. Identification that is persistent beyond the four walls of the company is key for a blockchain implementation, given the technology’s immutability. A universal data language that starts with product identification can ensure that the right data is stored and communicated further down the chain. 

Global Location Numbers (GLN) –  Similar to GTINs, these are numbers that uniquely identify organizations and locations in the supply chain. GLNs give companies the flexibility to identify any type or level of location required for supply chain visibility. They can identify a warehouse, a retailer, a hospital, even something as specific as a store shelf. Or, they can identify a company’s legal or functional entities as they relate to a particular business transaction, for example as buyer, seller, or carrier. 

So many blockchain use cases today revolve around supply chain visibility, with specific focus on locations and origins. For example, Nestle teamed with Carrefour to put traceability directly into the hands of consumers using the IBM Food Trust blockchain platform. Carrefour shoppers can track Mouseline instant mashed potatoes from Nestle’s factory to Carrefour’s stores by scanning a QR code on the packaging with a smartphone. In addition to providing extended product details, such as the product’s production date and quality control parameters, it also reveals the locations of warehouses and the farms that supply the potatoes. Without standardized location identification, such a level of transparency would not be possible. 

GS1 barcodes – For data to be shared among trading partners (with or without a blockchain), it must be captured. More trading partners, particularly in the food industry, are leveraging the GS1-128 barcode to capture dynamic product information and serialized logistics data, such as expiration date and batch/lot numbers. Using these barcode labels, companies enable the automatic recording of product-specific information whenever a barcode is scanned, for a more real-time view of where products have been and where they are going. 

Electronic Product Code Information Services (EPCIS) – EPCIS is like a standardized application program interface (API). EPCIS acts in a similar way to capture and share information about the movement and status – the what, where, when and why – of products, logistics units and other assets in the supply chain. EPCIS simplifies the capture and description of physical events, allowing companies to more effectively rely on a single version of the truth about supply chain and logistics events. 

EPCIS is increasingly deployed in sectors such as fresh foods, healthcare, and logistics to improve efficiency. It is versatile, in that it can be used with a number of different data carriers, including GS1 barcodes and EPC-enabled radio frequency identification (RFID). Unlike “batch oriented” data transmission mechanisms, EPCIS is more suitable for blockchain because it more efficiently documents the potentially massive amounts of event-based data. 

These concepts from the GS1 System are being incorporated into Hyperledger Grid from the ground up. Adopting standards means putting structure around both static and dynamic data.  Without a common platform to share data, blockchain applications may fail to deliver on promises of consistent efficiency and visibility. GS1 Standards have an inherent credibility, neutrality and interoperability to help make data usable for blockchain today and scale for tomorrow.
