Hyperledger in Action Across Asia

By Hyperledger Blog, Hyperledger Fabric, Hyperledger Sawtooth

It’s #HyperledgerAsia month, so we are spotlighting the fast-growing adoption and deployment of Hyperledger technologies throughout the region. Companies across Asia are driving a nonstop stream of innovative new enterprise blockchain implementations ranging from global shipping networks and international digital health passports to training certification and secure document solutions.

Read on for just a sampling of the solutions at work across Asia powered by Hyperledger technologies. And join the conversation using #HyperledgerAsia on social channels.

BondbloX Bond Exchange

Singapore-based BondEvalue broke through barriers when it unveiled the world’s first blockchain-based bond exchange that allows investors to trade BondbloX Bond Exchange (BBX) – $1,000 fractions of traditional wholesale bonds. This leads to better access and better diversification opportunities for a market that is typically inaccessible except to more wealthy investors.

BBX leverages the Hyperledger Sawtooth blockchain technology to fractionlize bonds, make trading highly transparent and more cost effective. Settlement on BBX is on a T+0 basis, that is within seconds instead of the normal two-day settlement cycle, thereby reducing counterparty settlement risks for investors.

BondEvalue continues to engage more member participants such as Taurus Wealth Advisors, the leading fee-based, multi-family wealth management firm in Singapore, and Amstel, an institutional fixed-income broker with operations across Asia and Europe. BondEvalue is also expanding its footprint with a joint venture partnership in Mexico. The company’s goal is to empower a more diverse pool of investors and introduce them to institutional-grade opportunities in the bond market through its cutting-edge blockchain solution.

Global Shipping Business Network

Global Shipping Business Network (GSBN), headquartered in Hong Kong, is a neutral trade data utility platform whose members include container carriers and terminal operators/ports that handle one in three containers worldwide. It is built on a Hyperledger Fabric-based permissioned blockchain with strong data governance where only authorized parties are granted the right to contribute and consume shipping related data. By leveraging immutability of the blockchain and data field level privacy through cryptography, participants in the supply chain such as terminals, carriers, shippers, freight forwarders, truckers, customs and financial institutions, can collaboratively design and enable industry wide, end to end, solutions. The platform was developed in partnership with Oracle, Microsoft, AntChain and Alibaba Cloud.

[markets]^N

Developed by KoinEarth and deployed using Hyperledger Fabric on Oracle Blockchain, [markets]^N is a secure B2B platform that’s used by India-based Hindalc, the world’s largest aluminum rolling company, to get a higher degree of visibility into its inventory and supply chain and enforce its SLAs with service providers. This includes tracking and monitoring of purchasing orders, shipments and invoices in real-time, in coordination with its suppliers.

Mindtree’s Digital Health Passport for Travel

Post-pandemic passenger air travel is constantly evolving due to border restrictions and COVID-related mandates. The need of the hour for airlines is to have a comprehensive and adaptive solution that informs and educates travelers, airline staff, airport authorities and government in real-time about COVID test requirements, safety protocols, vaccines and other regulations. Mindtree’s Digital Health Passport for Travel solution, which is built using Hyperledger Fabric blockchain technology, promises to do exactly this and thereby make post-pandemic global airline travel seamless, hassle-free, and safe.

MiFix Gateway

KrypC partnered with New Street Technologies to implement a blockchain marketplace for lending built on Hyperledger Fabric. MiFix Gateway is a distributed private network where participating financial institutions can access qualified leads and compete for customers seeking loans. Lenders view the credit score and personal information of each lead and offer competitive loans based on this information. MiFix provides a single platform where banks can earn revenue from loan disbursements and customers can obtain the most competitive rates while maintaining complete control of their data.

MiFiX connects remittance providers and banks to reduce interest rates. Though there have been efforts made by banks and financial institutions to provide affordable loans to rural parts of society, the last mile cost of collecting the loan pushes the cost to beyond affordable levels. By connecting the remittance companies in various corridors and lending institutions in India through a blockchain network, MiFiX is facilitating the sharing of remittance and loan information in a trusted and immutable fashion eliminating the collection cost.

SnapCert

SnapCert is a blockchain-based Credential Authentication platform for universities, colleges and institutes. Offered as a SaaS platform by Snapper Future Tech, SnapCert equips education customers to issue and verify credentials on a blockchain, ensuring no fraudulent credentials can be issued in their name.

Customers include Kushal, a social organization that trains unskilled labour under Indian government National Skill Development program. With SnapCert, verifiers can get real-time verification of Kushal credentials directly from the primary source of the data simply using the last four digits of the credential holder’s Aadhaar id and the name. The solution solves the problem of misplaced paper credentials and reduces the trust deficit by providing easy access to credible credentials that prove the holder’s construction training. It also helps Kushal manage long term record keeping for the skilled workers, connect stakeholders that need the data and increase transparency and ease of doing business.

SnapCert is built using Oracle Blockchain, which is powered by Hyperledger Fabric.

Secure Logistics Data Exchange

The Secure Logistics Data Exchange (SLDE) platform was launched by the Ministry of Commerce of India to digitize the generation, exchange, and compliance verification of 36 document types commonly used by banks, customs, freight forwarders, exporters, importers, and transport operations. The SLDE platform, which runs on the Hyperledger Fabric-based Oracle Blockchain, is a solution to replace the present manual process of generation, exchange and compliance of logistics documents with a digitized, secure and seamless document exchange system. It was developed by CargoExchange in conjunction with a number of banks (ICICI, Axis Bank, State Bank of India and HDFC Bank) and the ministry’s Logistics Division.

Tech Mahindra Document Solution

Tech Mahindra, in collaboration with a partner, has built a SaaS platform allowing companies to securely share sensitive documents with anyone within or outside the organization. Supported on Hyperledger Fabric, the platform enables mortgage companies, banks, accounting firms, and others to safely share their customers’ PII, IP, and sensitive information with co-processing entities in compliance with GDPR, CCPA privacy regulations.

Tech Mahindra is implementing the solution for the China division of a leading global manufacturer of consumer dispensing packaging and drug delivery devices. In the current engagement, Tech Mahindra will enable the customer to classify and securely share sensitive documents within or outside the organization with the help of advanced encryption, policies and immutable audit logs that are traceable on blockchain. Our solution will make information tamper-proof, and hack-proof thereby enabling our customer to transact with integrity and confidence with all internal and external stakeholders.

Hyperledger Foundation Community Training: Accelerate your decentralized identity skills with two free Hyperledger Indy and Hyperledger Aries workshops

By Hyperledger Blog, Hyperledger Aries, Hyperledger Indy

Hyperledger Indy and Hyperledger Aries are two of the popular open source repositories that can help propel development of decentralised identity products and services. Aries is a toolbox of several blockchain-agnostic repositories that allow for trusted online peer-to-peer interactions based on decentralized identities and verifiable credentials. The project grew out of work that was happening in Indy to create technologies for managing decentralized identity. Aries was moved to graduated status by the TSC in February 2021. Indy graduated in 2019 and provides a specific blockchain purpose-built for identity.

Seeing the growth in interest for these two projects, Hyperledger Foundation has partnered with member company Indicio and its team of deeply experienced developers and architects to develop this free, multi-course curriculum to help developers and architects gain a deeper understanding of decentralized identity, with a deep dive into Aries and Indy. Registration and preparation information can be found on this Workshops page.

These two four-hour, beginning level hands-on workshops provide opportunities to install and run the Indy and Aries components just like you would if you were making a real Indy-based network or Aries-based application. They introduce the necessary Git repos as well as how to use the Indy Command Line Interface (Indy CLI), run the Aries toolbox and create and issue a verifiable credential. They also introduce some current projects using Aries and Indy to help you accelerate your understanding of decentralized identity and build the skills necessary to successfully make changes to the underlying code with hands-on guidance to develop your own projects.

Hyperledger Fabric Security Threats: What to Look For

By Christopher Cordi, Software Engineer, Splunk. Blog, Hyperledger Fabric

Hyperledger Fabric is designed to enable secure collaboration between multiple organizations operating with limited trust. Despite the security improvements Hyperledger Fabric provides, deployments still require careful configuration and monitoring to ensure that they are operating securely. In this post, we will examine different types of threats that Hyperledger Fabric operators should consider and discuss how to mitigate them.

As a permissioned blockchain, Hyperledger Fabric’s network threats differ from popular permissionless chains. For example, 51% attacks and network partitioning attacks are not as significant of a threat on permissioned networks because users are known, their activities can be monitored, and access is managed by access control lists. Some of these attacks are common to all distributed systems like Denial of Service (DoS) or consensus manipulation. Other attacks target specific components in a Hyperledger Fabric network, such as the Membership Service Provider (MSP).

Denial of Service: DoS attacks disrupt the network’s availability and are a threat to any distributed system. Many different attacks can result in denial of service, which makes it difficult to proactively prevent. This risk can be mitigated by collecting performance metrics, such as transaction throughput and latency, to detect compromised availability early on.

Consensus Manipulation: Attacks on the network consensus include DoS and transaction reordering attacks. Hyperledger Fabric currently only utilizes Crash Fault Tolerant (CFT) consensus algorithms, meaning it cannot tolerate any malicious actors. There is ongoing work on Byzantine Fault Tolerant (BFT) algorithms, which will be able to tolerate up to ⅓ of the network being malicious. Regardless of the consensus algorithm used, early detection of malicious behavior can mitigate this threat. Logging threat indicators, such as leadership elections and transaction latencies, is critical for detection.

MSP Compromise: A compromised MSP can be a significant Fabric-specific threat. The MSP is able to modify access control to the network and, if malicious, could deny service and perform sybil attacks. The MSP may be compromised by a rogue insider or through private key theft, which may only be detectable after exploitation. To mitigate this risk, it is important to follow best practices with key management. Logging MSP actions, such as certificate creation and revocation, can help detect malicious behavior in case of compromise. Alerting based on that logging results in early identification and remediation.

Smart Contract Exploitation: While the cost of smart contract attacks is easier to quantify in cryptocurrencies, where there is measurable monetary loss, such attacks in Hyperledger Fabric can compromise business logic and network performance. In addition to ordinary programming logic bugs, common errors can also stem from inappropriately handling concurrency or nondeterminism. To mitigate this risk, smart contracts should be designed with security in mind at the onset by following a secure software development life cycle framework. Before deploying, smart contract security should be assessed with smart contract analysis tools like the Hyperledger Lab Chaincode Analyzer to detect potential risks. For more sensitive applications, consider an external security audit or formal verification. Finally, the performance and usage of the smart contract should be monitored once deployed in order to detect anomalous behavior.

Proactive measures to mitigate these security threats are only part of a secure deployment. It is just as important to continuously monitor the performance and security of the network. Many of these threats can only be detected by correlating data across the blockchain network, organization infrastructure, and threat intelligence providers. It can be a challenge to ingest and act on this large amount of diverse data, so be sure to account for scalability and analytic capabilities when securing your environment.

For more details on how to collect and act on Hyperledger Fabric data to minimize downtime, reduce the meantime to detect and respond to incidents, tune into my webinar on Hyperledger Fabric security monitoring on Wednesday, December 1, 1:00 pm EST.

Splunk Adds Hyperledger Fabric Data Visibility into Mix, Powers New Blockchain-Based Content Management Solution for S&P Global

By Hyperledger Blog, Finance, Hyperledger Fabric, Member Case Study

Read the full case study here.

Large organizations have always struggled to get visibility into their data. Frequently, data comes in many sources and formats while also being siloed across the organization. DLTs add ledger data and metadata to the mix.

Similarly, consortiums need to interoperate with each other. Yet organizations often use disparate tools for logs, metrics and tracing. All these are deployed on different clouds or on-prem. Then they build their own tools to take data from the ledgers and put it into a SQL database. Consortiums may include competitors who don’t trust one another, so they don’t want to share data. But, if no one shares data, it can be challenging to determine if an organization has a problem or if it lies in the network.

Splunk, a company focused on removing barriers between data and action, took on this challenge by creating open source solutions that allow the ingestion of ledger data and corresponding metadata while correlating with other data sources.

Splunk’s customers include 92 Fortune 100 companies. Meeting their needs was critical so Splunk asked a lot of questions. They learned that many customers used Hyperledger Fabric, and it was fairly straightforward to ingest that DLT data. Splunk pulls in data without caring about structure, schema, or form so there was no need to format Hyperledger Fabric data before ingestion.

The next questions were about what they could do with the Hyperledger Fabric data. Users could analyze and correlate blocks and transaction data with other data they had in Splunk. But conversations with customers revealed they wanted more, including chaincode events, metrics, and, most recently, private data collections.

Initially, Splunk focused on uses from an IT perspective. Then the focus shifted to security. Customers wanted to know what else they could do to secure their infrastructure. Keeping it up and running was important, but so was making sure nothing would compromise their Hyperledger Fabric environment

One of those interested customers was S&P Global, which delivers data, research, and credit ratings, among other things, to governments, companies, and individuals. In 2019, it was entering a new region. S&P took this opportunity to explore modern technologies and new ways of doing business. It decided to build a content management solution from scratch with innovative technology and security.

Splunk’s Hyperledger Fabric-based applications caught S&P’s attention. Leveraging the Fabric data in Splunk meant S&P could now get user interactions and metadata—like who uploaded documents or modified documents and when. S&P developed applications to retrieve that metadata and present it to the user for document searches. This opened up possibilities for providing an audit trail.

The resulting solution, S&P Global Secure Vault, is multi-cloud, multi-tenant, and secure, and it is ready to scale to multiple regions and multiple participants. In the solution, S&P uses Splunk for three primary areas. The first is infrastructure monitoring on the operations of different components. The company wants to make sure the system stays healthy and the right teams are alerted if there’s an issue. The second is visibility into the events happening within the blockchain network. And third is business activity monitoring, which includes searching for document metadata.

Hyperledger worked with Splunk and S&P Global on a case study that details this blockchain-based secure content management system and how the companies partnered to add visibility into business transactions, making them indexable and searchable. It also delves into Splunk’s commitment to open source software and plans for helping customers that use Hyperledger Fabric get even more from their data.

Welcome to the 2021-2022 Technical Steering Committee

By Hyperledger Blog

Each year, the Hyperledger technical community holds an election to select a new Technical Steering Committee (TSC) from the community at large. The main objective of the TSC is to drive technical governance for the projects and technologies hosted by the Hyperledger Foundation. The 2021-2022 TSC was just elected and that group of 15 members, in turn, voted in the chair and vice chair for the group.

This year, the TSC will be led by Tracy Kuhrt, Associate Director, Blockchain and Multiparty Systems Architecture, Accenture (chair) and Danno Ferrin, Principal Software Engineer, Hedera (vice chair). To kick off their tenure in these roles, we asked Tracy and Danno to weigh in on goals, opportunities and technologies they have their eyes on for the next year. Here’s what we learned:

Q) What are some of the goals you have for the TSC/community for the year ahead?

Tracy: Communities are stronger when we listen and learn from others. Last year, during the TSC one of our initiatives was “breaking down the silos.” In addition to the discussions held in the community, the 2021-22 discussed some actionable items:

sponsoring a project that ties together different projects to encourage cross-pollination and showcasing the different projects within the Hyperledger Foundation
sharing the cool technology that is coming out of our different projects
attending meetings in the community that we would not otherwise attend

Communities are also stronger when everyone is welcome, and people feel like they belong. In addition, we need a diverse set of opinions. We hear from many of our projects that they would like to have more contributors. Contributions are not just writing code. There is a need for many different skill sets, including (but not limited to) writing documentation, filing issues when you find something wrong in the code or the documentation, blogging about your experience with one of the projects, and answering questions that others have.

Q) What’s the most important role that TSC plays in guiding the development efforts for Hyperledger?

Danno: The most important role that I see is that the TSC provides project oversight to the various projects in the Hyperledger Foundation. And these projects exist on a wide spectrum of maturity. They vary from a Hyperledger Labs project, where there may be one dedicated developer implementing their bright idea, all the way to Hyperledger Fabric, which has multiple sub-projects supporting the main DLT. We should make sure these projects are functional, see to it they are healthy, and to provide them the feedback they need to hear to help them grow.

Q) What are some of the challenges the TSC faces in the next year? Opportunities?

Danno: When Hyperledger was first formed, there were very few enterprise capable DLTs on the market, and none that had received wide adoption. Fast forward to today and five of the six projects that have graduated are all enterprise capable DLTs, so I feel that space is fairly well filled out. The challenge is growing out the ecosystem beyond these base level enabling technologies. The sixth graduated project, Hyperledger Aries, is a good example of a project that works past the base layer. In this case, it works with enabling verifiable credentials. I think the challenge the TSC faces is how do we nurture and create more projects like this that provide the frameworks, tools, and libraries needed to support the DLTs and multi-party systems at the core of the ecosystem

Q) Are there emerging technologies or challenges you see as opportunities for new projects?

Tracy: As a Hyperledger Lab Steward, I am among the first to see some of the interesting things that the community is thinking about and developing. We have multiple top-level projects (Ursa, Cactus, and the yet to be named blockchain automation framework) that came out of Hyperledger Labs, and I expect that we will see more in the future. I recently put together a word cloud on the different labs, and there are labs that are focused on interoperability, development tools and SDKs, operations, deployment, management tools, and applications. People are looking to make using and operating blockchain networks easier as well as integrating those blockchain networks into their existing systems or other ecosystems.

Are there any project milestones coming that you are watching with interest?

Danno: Even though I don’t work in the consensus portions of Hyperledger Besu anymore, I have my eye on the APIs being used to enable “the merge” on Ethereum Mainnet. The mainnet team at ConsenSys in their role as Ethereum core developers are working on an RPC API where the consensus is maintained by a separate process rather than in Besu itself. I think there is a great opportunity for a new contributor to leverage that work and either write a bridge service or modify Besu itself so that enterprise instances of Besu can use RAFT and other external consensus managers.

Here is the full list of TSC members:

Angelo De Caro, IBM
Arnaud J Le Hors, IBM
Artem Barger, IdeaDLT*
Arun S M, Walmart
Bobbi Muscara, Ledger Academy
Danno Ferrin (vice chair), Hedera
David Enyeart, IBM
Grace Hartley, ConsenSys
Hart Montgomery, Fujitsu
Jim Zhang, Kaleido*
Kamlesh Nagware, Snapper Future Tech*
Nathan George, Kiva
Peter Somogyvari, Accenture*
Tracy Kuhrt (chair), Accenture
Troy Ronda, SecureKey

*New to the TSC for 2021-2022.

Hyperledger Performance and Scale Working Group Guest Presentation: Fast-HotStuff Consensus Protocol

Join the Performance and Scale Working Group for a talk by Mohammad Jalalzai from UBC on “Fast-HotStuff Consensus Protocol.” The HotStuff protocol is a recent breakthrough in Byzantine Fault Tolerant (BFT) consensus that enjoys both responsiveness and linear view change. It creatively adds an additional round to classic BFT protocols (such as PBFT) using two rounds. Despite its great advantages, HotStuff has a few limitations. First, the additional round of communication during normal cases results in higher latency. Second, the current version of HotStuff is vulnerable to certain performance attacks. This talk will cover a proposed new two-round BFT protocol called Fast-HotStuff, which enjoys responsiveness and efficient view change that is comparable to linear view change in terms of performance. Fast-HotStuff has lower latency and is more robust against the performance attacks that HotStuff is susceptible to.
