Understanding Hyperledger and Its Core Technologies
The Linux Foundation, based in San Francisco, is home to influential open-source initiatives, including Hyperledger. This executive-led project is dedicated to advancing collaborative efforts in blockchain and distributed ledger technologies.
Brian Behlendorf, Executive Director of Hyperledger, describes the Linux Foundation’s role in spearheading collaborative software projects. Hyperledger, established in December 2015, specifically aims to broaden the adoption and understanding of distributed ledgers and smart contract systems.
The Hyperledger community has cultivated a robust ecosystem comprising 15 distinct technology codebases, also known as projects. Among the early foundational projects are Hyperledger Fabric and Hyperledger Sawtooth. Behlendorf points out that while both are general-purpose distributed ledger systems, they are built with significantly different architectural foundations.
Hyperledger Fabric is engineered as a modular framework for building applications. Its plug-and-play design allows for the interchangeable use of components such as consensus mechanisms and membership services. Key cloud providers, including Alibaba, Amazon Web Services, Microsoft Azure, and IBM, have adopted Hyperledger Fabric.
In contrast, Hyperledger Sawtooth provides a flexible architecture that separates core system functions from application-specific domains. This separation allows smart contracts to define business rules without requiring an understanding of the underlying core system’s intricacies. Salesforce’s blockchain platform, for example, is developed on Hyperledger Sawtooth.
Revolutionizing Industries with Blockchain Technology
Blockchain’s Impact on the Aerospace Industry
The global aerospace parts manufacturing market, a sector valued at over $900 billion in 2019, is on a trajectory of steady growth. However, establishing and maintaining trust remains a significant challenge within this complex industry.
Lisa Butters, General Manager at Honeywell, underscores the potential of blockchain technology to instill greater confidence in the aerospace sector. Honeywell Aerospace, a long-time supplier to leading commercial aircraft manufacturers, launched GoDirect Trade in 2019. This innovative platform leverages Hyperledger Fabric.
GoDirect Trade operates as an online marketplace specifically for pre-owned aerospace parts, a segment accounting for approximately $4 billion annually. The platform utilizes blockchain to meticulously verify the provenance of parts and ensure adherence to critical safety standards. As Butters explains, GoDirect Trade functions much like Carfax does for used cars, but instead of relying on verbal assurances, blockchain provides consumers with documented information regarding a part’s history and previous ownership.
The platform significantly enhances supply chain visibility by creating an instant connection between different layers as aviation parts move through the system. All transactions are recorded on a unified, shared ledger, fostering transparent tracking of item movements. This approach stands in stark contrast to traditional methods that depend on paper-based records, which are susceptible to loss and potential forgery.
Currently, less than 3% of the used aerospace parts market is transacted online, a low figure attributed largely to the reliance on paper documentation. GoDirect Trade aims to disrupt this trend by facilitating online sales and has already recorded $7 million in transactions within its inaugural year.
The platform caters to the top 100 airlines worldwide, with over 70 manufacturing and repair shops partnering with Honeywell. Despite these successes, integrating blockchain ecosystems with major airline companies presents challenges, particularly concerning the secure sharing of data.
Hyperledger Fabric’s private and permissioned nature addresses this concern by requiring explicit authorization for companies to participate. This ensures secure data exchange within the network. Organizations can establish digital storefronts on GoDirect Trade, and trusted partners can list parts directly through API integrations or file transfers to Honeywell.
Butters anticipates substantial growth for GoDirect, with targeted revenue projected to increase significantly in the coming years. She states, We are using blockchain to build trust between our buyers and sellers. We expect to see a growing interest in organizations looking to use our platform.
American Express Enhances Rewards with Blockchain Flexibility
American Express is strategically employing blockchain technology to introduce enhanced flexibility into its renowned rewards program. Michael Concannon, Vice President of Technology at American Express, outlines the objective: to empower merchants to create bespoke offers using AmEx Membership Rewards points on their own platforms, thereby fostering greater partner engagement and improving card member benefits.
Traditionally, card members accrue a fixed number of points per dollar spent, redeemable for gift cards or travel. The new system empowers retailers to design targeted reward campaigns based on specific brands, products, timing, or customer segments.
💡 Hyperledger Fabric serves as the foundational technology for this flexible rewards blockchain. American Express utilizes a Hyperledger Fabric network, where merchants operate AmEx-hosted nodes. Merchants can input data into these nodes, which then triggers smart contracts to generate reward points.
Once generated, AmEx’s node transfers these points to its existing rewards system and backend infrastructure, enabling card members to view and utilize them seamlessly. The online retailer Boxed was an early participant, piloting the program in March 2018 and now offering bonus Membership Rewards points on eligible purchases.
Rakuten, formerly known as Ebates, also partnered with AmEx in 2019, offering Membership Rewards points as an alternative to cashback for purchases made through affiliate links. This offer was subsequently expanded to all Rakuten members.
Concannon highlighted Rakuten’s pioneering approach with a behavioral-based model, allowing users to earn points based on specific actions rather than solely on card spending. He noted, If consumers link their accounts to Rakuten, they are able to redeem their rewards as Amex Reward Points.
American Express is also developing an internal blockchain solution named Vendor Invoicing Validation and Reconciliation. This system employs Hyperledger Fabric to streamline invoice reconciliation processes for AmEx contractors and vendors, facilitating quicker payments and reduced cycle times by matching invoices with purchase orders and timesheets.
The blockchain network ensures transaction visibility for all involved parties. In addition to its flexible rewards program, American Express filed a patent for a blockchain-based proof-of-payment system in 2018, which is currently under review.
Securing the Gemstone Industry with Blockchain Transparency
Klemens Link, Head of Development at Gubelin Gem Lab, recognizes the significant potential of blockchain within the multi-billion dollar gemstone industry, an sector historically reliant on paper records susceptible to fraud and manipulation.
Gubelin Gem Lab has collaborated with blockchain company Everledger to introduce its Provenance Proof Blockchain. Link explains the core vision: to create a digital log book for each and every gemstone telling the story from the mine all the way to the market.
The Provenance Proof Blockchain is an open platform powered by Hyperledger Fabric, accessible to industry participants at no charge. Gubelin Gem Lab’s Emerald Paternity Test utilizes this platform, employing DNA-based particles encoded with mine-specific information to trace a gemstone’s origin from its creation to its market presence.
Data is immutably recorded on the Provenance Proof Blockchain at every stage, ensuring unparalleled transparency and traceability. This process requires only a smartphone with internet access for both data recording and verification.
Moyo Gemstones, an ethical gemstone initiative from Tanzania collaborating with the Tanzanian Women Miners Association (TAWOMA), utilizes the Provenance Proof Blockchain. This partnership enables secure tracing of gemstones from source to market, enhancing transparency and empowering female miners with improved safety, better mining practices, and greater financial security.
Purchasers can gain confidence that the gemstones they acquire are not the product of unethical practices, thereby increasing their intrinsic value. However, challenges persist, most notably in providing support for small-scale miners in remote areas with limited internet connectivity.
Striking a balance between consumer transparency and stakeholder privacy presents another hurdle. Link notes, We don’t want to risk anybody’s security through exposing private data. Despite initial skepticism, the initiative has experienced growing interest, with 200 companies currently utilizing the platform and many more expressing a desire to join.
Blockchain: Enhancing Trust in Trustless Systems
Due to its open-source nature, an exact figure for the number of businesses utilizing Hyperledger Fabric is not available. However, prominent organizations such as Honeywell, American Express, and Everledger are among those leveraging it to introduce trust into traditionally opaque industries.
💡 Hyperledger Fabric is also being employed by Voatz to bolster transparency in national voting systems and is being applied to ensure the reliability of COVID-19 data for health officials.
When Behlendorf joined Hyperledger, the community engaged in discussions about whether to focus on a single solution or provide a versatile backbone supporting multiple architectures. The consensus was to create a core infrastructure for blockchain technology that could integrate with and complement various projects, all unified by the goal of bringing trust and transparency to diverse industries.
