#HyperledgerIdentity round-up: A cross section of production digital identity solutions built using Hyperledger technologies

By Hyperledger Blog, Hyperledger Aries, Hyperledger Fabric, Hyperledger Indy, Hyperledger Ursa, Identity

Verifying identities and information in a digital world is critical for establishing trust. But there are issues of privacy as well as efficiency, scale and accuracy in models that rely on centralized data collectors and databases.

The adoption of a new generation of digital identity solutions that leverage decentralized technologies such as distributed ledgers and verifiable credentials is accelerating. And Hyperledger technologies are playing a major role in this transformation.

Read on for a cross section of the many Hyperledger-powered solutions that are in production now. For other examples, check out these past #HyperledgerIdentity round-ups:

IBM Digital Health Pass

IBM Digital Health Pass, built on Hyperledger Fabric, offers a multi-credential verifier that organizations can use to manage and execute their verification policies for COVID-19 and vaccination status in a way that balances the privacy of the individual with the requirements set by the organization and local health authorities. With IBM Digital Health Pass, organizations can verify multiple types of health credentials, such as Good Health Pass, IBM Digital Health Pass, Smart Health Card and EU Digital COVID Certificate. Privacy is central to the solution, where the verifier application minimizes the personal data that is ever displayed to the user through the execution of business rules and it never lets any personal data leave, or be stored in, the verifier app.

Indicio Network

The Indicio Network is a collection of four professionally-staffed, enterprise-grade public-permissioned ledgers that provide a neutral, independent, and reliable network for the exchange of verifiable credentials. MainNet, DemoNet, TestNet, and TempNet are all Hyperledger Indy-based networks with nodes operating on five continents—and a growing number of node operators. The Indicio Network is one of the networks that can support Indicio Proven, a complete suite of decentralized identity components for authenticating and sharing high value data in a privacy-preserving way using verifiable digital credentials. Built on Hyperledger Aries and Hyperledger Ursa, as well as AnonCreds and DIDComm, Proven is designed to make implementing and using these open source codebases simple, providing users with a fully-owned solution that’s easy to integrate with existing systems, to innovate on, and to scale.

IDUnion

IDUnion, the European identity verification network created as part of the “Secure Digital Identities Showcase” funding project, brings together public institutions, government agencies, private organizations, associations, educational institutions and other stakeholders from various fields to enable a fundamentally new, secure digital infrastructure for the verification of identity information. In August, 2022, IDUnion spun off Sociedad Cooperativa Europea (SCE) to operate the production network for credential verification.

The IDUnion network, which is built on Hyperledger Indy, enables the clear verification of individuals, companies and institutions while allowing people and organizations to manage their identity information by themselves and to decide when they want to share this information and with whom. It has a decentralized structure and stores no personal data – not even as a hash. In order to protect privacy right from the start, all personal data is stored on the user’s end device. Users have a choice of wallets for storing and presenting credentials to third parties as required. Credentials are issued, verified and stored using open standards to ensure interoperability. Hyperledger Aries is the framework for managing the credentials.

NHS Covid-19 Digital Staff Passport

In 2019, the NHS was preparing to pilot a digital passport project that would allow staff to carry their HR and other records as credentials on their phones as a long-term plan to make it easier to transfer from one facility to another. When the pandemic hit, this went from a pilot to a production deployment quickly. The NHS Covid-19 Digital Staff Passport rolled out in summer to support swift and efficient staff movement between NHS organizations in response to the response health emergency. The COVID-19 Digital Staff Passport provided a solid legal framework for staff to be temporarily deployed into other NHS organizations with evidence available that checks have been completed before staff move. As laid out in the pilot, the information was transferred securely by the staff member as verified credentials stored on their own smartphone, putting them in control.

This staff passport used the Sorvin Network, which is built on Hyperledger Indy, to verify the digital credentials, and the Evernym (now Avast) Connect.me digital wallet app, which is powered by Hyperledger Aries, Indy and Ursa, to enable staff to store and share their credentials.

The NHS is now gearing up to roll out the next generation of its Digital Staff Passport, which will streamline transfers and staff movements through the NHS.

OrgBook BC

OrgBook BC is a searchable public directory of organizations registered in British Columbia, Canada, provided by the BC Government’s Ministry of Citizens’ Services. OrgBook BC provides verified data, including legal names and DBA names, business numbers, BC registration status and select licensee and permits, for more than 1.4 million organizations. All of the information in the OrgBookBC is received, stored, verified and displayed using the latest digital trust technologies.

OrgBookBC uses verifiable credentials to ensure that information about organizations are digitally signed by the entity that issues it. Issuers are public sector organizations that hold information about businesses, issue licenses or permits or certify processes. That electronic signature stays with the data throughout its life in OrgBook and is validated before its is display on the website.

OrgBookBC is part of an overall commitment to digital trust technologies by the Government of British Columbia. In addition to deploying Hyperledger Aries, Indy and Ursa, the team there is leading much of the open source development for those projects.

Energy & Mines Digital Trust: The Open-Source Journey Towards a Clean, Resilient Economy

By Energy & Mines Digital Trust Blog, Climate, Hyperledger Aries, Hyperledger Indy, Identity

As the world works towards climate goals, a government project from Canada is using digital trust technology to make it easier and more secure for natural resource companies to share sustainability data.

Energy & Mines Digital Trust (EMDT) was established by the Government of British Columbia in recognition that we must do more to facilitate the transition to a clean, resilient economy. British Columbia (B.C.), Canada’s western-most province, was the first province in Canada to implement greenhouse gas emission reduction targets and mandatory sustainability reporting for major sectors of the provincial economy. As leaders in climate change legislation, B.C. is well positioned to explore cutting-edge technology in the journey towards a low-carbon economy. To improve trust, accuracy, and efficiency when sharing sustainability data, EMDT is coordinating a digital ecosystem – a network of organizations including environmental auditors, government bodies, mining and energy companies, and non-government organizations.

Improved Sustainability Reporting

Currently, reporting sustainability data can be challenging. Data is difficult to exchange internationally, and consumers cannot always access, or trust, reported data, not to mention the administrative burden.

EMDT’s digital ecosystem makes it possible to exchange sustainability information simply and securely, using digital credentials.

Digital credentials:

Can be shared quickly and are tamper-proof.
Allow companies to control their data.
Guarantee the integrity of the information.
Preserve privacy in business-to-business interactions.

Digital Trust Ecosystem: EMDT Pilot

EMDT has been testing and refining their technology and governance through multiple pilot projects to demonstrate how sustainability reporting can be made more efficient and trustworthy. Two pilot projects explore greenhouse gas emissions reporting in the mining sector and the natural gas sector. These pilots allow participants to test sharing and receiving digital credentials that include verified GHG emissions data for a specific mine site or natural gas facility.

*Because this is a pilot, the process depicted in this diagram does not satisfy or replace existing regulatory reporting obligations.

The greenhouse gas (GHG) mining pilot builds upon the existing regulatory emissions reporting process in British Columbia. PricewaterhouseCoopers (PwC), an environmental auditor, issues a digital credential to Copper Mountain Mining Company containing verified GHG data. Copper Mountain can then use the Greenhouse Gas Emissions Report Verification Credential as part of their GHG emissions report to British Columbia’s Climate Action Secretariat. Copper Mountain can use the same digital credential to complete voluntary reporting to organizations such as the Open Earth Foundation.

Increased Connections

To facilitate the broad exchange of sustainability data, EMDT used Hyperledger Indy and Hyperledger Aries to create a highly interoperable tool, called Traction. Traction is an API accelerator built on top of Hyperledger Aries Cloud Agent Python (ACA-PY). Traction streamlines the process of sending and receiving digital credentials for governments and organizations.

Hyperledger Aries makes Traction highly interoperable with the technological solutions of companies and organizations around the world. “While two wallets might be different implementations or might be written in different code, they can still exchange data because both wallets use Aries,” explains Kyle Robinson, EMDT’s Senior Strategic Advisor.

Traction makes it easier to integrate digital trust technology into existing lines of business:

API-first Architecture: Traction is designed with an API-first architecture. This RESTful API allows for integration into existing line-of-business applications already being used by organizations. The Tenant user interface is built on this API to enable adoption prior to integration and for low-use functions.
Multitenancy: ACA-Py is implemented on a cloud-based server so multiple wallets can be managed with one Traction instance.
Higher Scalability: Traction is open-source technology, encouraging collaborative refinement, faster release, and higher scalability of the technology.

Collaborative Climate Change Progress

With an increasing emphasis on responsibly sourced products, simplified methods for exchanging sustainability data ensures that B.C. natural resource providers can compete in a global market. Digital trust technology streamlines access to trustworthy sustainability data, allowing businesses, governments, and non-government organizations to work towards climate change goals more efficiently and effectively.

Project and Ecosystem News

New Project: Hyperledger Solang

The Hyperledger Technical Steering committee approved a new project, Hyperledger Solang, which is a compiler for Solidity source code and targets different blockchains. The Solidity programming language is the most popular language for smart contracts, and there is clear interest from many blockchains to have support for it. Although some blockchains emulate an EVM environment to maintain compatibility with Solidity built with Solc, they then cannot access features that are missing from Ethereum. Hyperledger Solan offers the ability to compile Solidity to the native execution environment, opening up access to new features and creating many possibilities for innovation in the Solidity language.

Currently, Hyperledger Solang supports Solana and Polkadot (Substrate).

Hyperledger FireFly 1.1 Release

A new Hyperledger FireFly release, version 1.1, includes new functionality that makes it possible for FireFly users to deploy multiple blockchain applications connecting to multiple chains from a single console. The FireFly Supernode now supports two operation modes: Web3 Gateway and Consortium. Web3 Gateway mode configures the FireFly Supernode to connect to a number of chains with transaction orchestration and state indexing. A revamped and expanded connector framework now includes EVMconnect, a robust connector for simple connection management to public blockchains with templates available for Ethereum, Polygon, Avalanche, Optimism, BNB Chain, and more. Consortium mode activates a number of capabilities for FireFly nodes to connect in a B2B network and exchange data through off-chain and on-chain rails. FireFly also now supports multi-tenancy through the use of namespaces. These new features enable enterprises to accelerate their web3 adoption.

Creation of Hyperledger Cacti

In a Hyperledger first, the community has decided to merge two systems (architectures as well as code bases). Hyperledger Cactus and Weaver, a Hyperledger Lab, will come together to be Hyperledger Cacti, a multi-faceted interoperability platform that will draw on the cutting-edge technical features of Cactus and Weaver and provide a clear path forward for users of both technologies.

Hyperledger Besu Client Incentive Program Kicks Off

The Ethereum Foundation (EF) has opted to include Hyperledger Besu in the Execution Layer Client Incentive Program (ELCIP) to foster the community development of enterprise-grade blockchain software. The program, which kicks off with the Merge, will provide execution-layer client teams with locked ETH in the form of live validators to be released according to certain milestones, including post-merge performance and progress towards enabling withdrawals from the beacon chain.

Hyperledger Besu is one of the top three most popular Ethereum execution clients according to Ethernode. EF is making this strategic investment to engage the Hyperledger Besu community in ensuring a diversity of clients and overall health of the network.

“The diverse community is what makes Ethereum special, empowering from builders in underserved or emerging economies to leading enterprises and beyond,” said Aya Miyaguchi, Executive Director at Ethereum Foundation. “Similarly a diverse client distribution helps keep Ethereum distributed and healthy, and I applaud the Hyperledger Besu team for their Execution Layer work for Ethereum, and wish you all a great Global Forum this year.”

New, Free “Getting Started with Self-Sovereign Identity” Course

To make it easier for enterprises to implement Self-Sovereign Identity (SSI) to put their users at the center of their digital identity, Linux Foundation Training & Certification has released a new online training course, Getting Started with Self-Sovereign Identity (LFS178x).

Meet Hyperledger Solang, a portable Solidity compiler

By Sean Young, Lucas Steuernagel, Cyrill Leutwiler Blog, Hyperledger Solang

We are excited to announce that Solang has been accepted as the latest Hyperledger® project and has been renamed as Hyperledger Solang™. The project is now formally being incubated as a top-level project by the Hyperledger Foundation™, hosted by the Linux Foundation, and has support from multiple sponsors.

Solang started in the Hyperledger Labs since we always wanted to work together with other Hyperledger projects. The very first ledger we supported was Hyperledger Burrow. Being part of Hyperledger Labs was a great way to give the project more visibility and ensure we could make use of the great tooling provided by Hyperledger. After tapping into those resources, Hyperledger Solang, a tool that enables smart contract portability, is now the newest Hyperledger project.

What is Hyperledger Solang

Hyperledger Solang is a compiler for Solidity source code and targets different blockchains.

The idea for Solang arose from early work on Hyperledger Burrow. We were trying to do things with Solidity that were not possible with the existing Ethereum Solidity compiler. Since that compiler is specific for Ethereum, there was no interest in supporting features for Hyperledger Burrow. From that problem, a portable Solidity compiler that could support many blockchains was born, making it possible to have different features depending on which blockchain is being targeted.

The Solidity programming language is the most popular language for smart contracts, and there is clear interest from many blockchains to have support for it. Although some blockchains emulate an EVM environment to maintain compatibility with Solidity built with Solc, they cannot access missing features from Ethereum that an emulated EVM environment cannot provide, such as cryptographic functions, like blake2, zero-knowledge proof and the ability to call native contracts or be called by them. Hyperledger Solang offers the ability to compile Solidity to native execution environments other than the EVM, allowing the language many new possibilities and innovations.

Currently, Hyperledger Solang supports Solana and Polkadot (Substrate).

How to use Hyperledger Solang

Hyperledger Solang compiles Solidity into a native contract and a corresponding metadata file. Deploying a compiled contract needs tooling from the corresponding target blockchain.

First follow the installation guide for installing Solang: https://solang.readthedocs.io/en/latest/installing.html and then follow the steps for Solana https://solang.readthedocs.io/en/latest/targets/solana.html or Substrate https://solang.readthedocs.io/en/latest/targets/substrate.html

For Solana, we have the @solana/solidity npm package for deploying and interacting with Solang compiled contracts. To compile Solidity for Solana, use:

$ solang compile –target solana source.sol

This will produce an ABI file for each contract, and a single binary contract called `bundle.so`.

For Polkadot or Substrate, the native @polkadot/api-contract npm package can be used. The command line for compiling Solidity for Substrate is:

$ solang compile –target substrate source.sol

For each contract found in the file a `.contract` file is produced.

There are examples in the documentation and in the integration tests of how to run these contracts.

We also have a visual studio code extension, which provides real-time compiler warnings and errors as well as type information when you hover over variables and functions.

What’s next

Language support: Hyperledger Solang already supports nearly all the syntax that Ethereum Solidity 0.8 supports. There are a few minor exceptions like slices. We intend to keep up with the latest Solidity developments as they are released.

Stabilized targets: Both the Solana and Substrate targets are undergoing stabilization and are expected to be finished by the end of the year. Once this happens, we expect many more users. We are aware of blockchain development teams wanting to use Hyperledger Solang in production, which makes this point a priority.

EVM support: Hyperledger Solang used to have an ewasm target. However, since ewasm is no longer going to happen on Ethereum, this target has been dropped. In fact, we have bigger plans: we renamed most of the ewasm target to EVM, and hope to have EVM support in the future. An EVM target would be an interesting development because it would bring Solang to Ethereum and any other EVM based chain. Many projects that are already developing for Ethereum are interested in running their contracts in multiple environments, using a single tool that compiles for EVM and other blockchains. We are considering running a Hyperledger mentorship for this difficult but rewarding task next year.

Hyperledger projects: We have had conversations with Hyperledger Sawtooth, Hyperledger Fabric, and Private Data Objects, which expressed interest in having Solidity support, but there is still work to be done to implement a new target in Solang for these projects.

Hyperledger FireFly V1.1 Is Now Available

By Nicko Guyer, Sr. Full Stack Engineer at Kaleido and Hyperledger FireFly Community Lead Blog, Hyperledger Firefly

Before Hyperledger FireFly, blockchain developers spent a lot of time building the plumbing of their application. They built complex middleware components from scratch. Hyperledger FireFly was a sea change. The first open source Supernode, Hyperledger FireFly offers developers a complete stack to build and scale secure web3 applications.

Hyperledger FireFly accelerates development with a rich stack of native web3, B2B, and integration services. It simplifies the deployment and management of many apps via a single console, and offers a new tool to connect to the multi-chain and multi-protocol web3 world.

This is more important than ever as public and private chain use cases intermingle more and more in novel enterprise applications. That’s what makes the new release of Hyperledger FireFly exciting. Developments to the stack make it radically simple for developers to launch production-ready apps on both public and private chains and manage multiple applications from a single console with multi-tenant support, plugin flexibility, and pluggable security.

Introducing Web3 Gateway Mode

Hyperledger FireFly can now operate in two modes. The first is familiar to current users of the stack. Consortium Mode is used to build consortiums or multi-party business networks where data needs to be agreed to and shared among the group. Use cases for Consortium Mode have included healthcare and insurance consortiums, supply chain participants, financial networks, and other examples where companies come together to streamline how they do business.

This release introduces the new Web3 Gateway Mode. Gateway Mode is used when the main goal of the Supernode is to connect to a public blockchain. Where previously developers could use a public tether to access popular public chains, this new mode acts as a doorway into the full world of web3 with support for popular public chains including Ethereum, Polygon, Avalanche, Optimism, BNB Chain, Arbitrum, Moonbeam, Fantom and more.

The worlds of public and private blockchain are merging. Enterprises are eager to tap into the reach, security, and decentralization of public chains. At the same time, public chain players are looking to optimize throughput, scalability, and gas fees in ways that have long been familiar to enterprise networks. This release of Hyperledger FireFly offers a stack to build for both worlds.

Public Blockchain Support

Along with the ability to connect across public chains, Hyperledger FireFly 1.1 has new tools and support to simplify public use cases for the enterprise.

FireFly Transaction Manager, an all new EVM Connector, handles the complex concerns of public chains, including gas estimation, resubmission policies, and more.
FireFly Signer can be used for transaction signing in networks where it is necessary to separate private keys from the blockchain node.
Enhanced Gateway Support makes it easy to keep private data private, while interacting with public chains.

Hyperleger FireFly 1.1 allows developers to access both public and private chains simultaneously, while building in guardrails specific to the enterprise space, ensuring new applications meet both user and compliance requirements.

Multi-tenant Support

Hyperledger FireFly 1.1 adds namespace isolation for segregating data and operations. Inside the Supernode, each namespace is an isolated environment within a FireFly runtime. This allows independent configuration of plugin and infrastructure components, API security, identity broadcasting, on-chain data indexing, and management of how data should be shared.

Namespaces work in both modes. Consortium Namespaces can be used when multiple parties need to share on- and off-chain data and agree upon the ordering and authenticity of that data. While Web3 Gateway Namespaces are available when interacting directly with a blockchain, without assuming that the interaction needs to conform to FireFly’s multi-party system model.

A single FireFly node can run multiple namespaces in either mode at the same time. This lets developers build flows that coordinate between public chains and private consortiums. The diagram below illustrates the visibility and control available to an organization as they run multiple applications from a single console, each segregated to meet security requirements.

Multiple Instances of Plugins

With the new release, a single FireFly node can now use several instances of each type of plugin that is available. As we illustrated above, we’re connecting to multiple blockchains simultaneously, often for different use cases or goals. The ability to run different plugins in each namespace means a developer has greater agility to coordinate flows for each chain or consortium.

Pluggable API Security

The flexibility to connect to multiple applications and multiple chains is only valuable in the enterprise space if it can be matched with the appropriate security, both for the integrity of the network and for compliance standards.

With Hyperledger FireFly 1.1, API Security can be enabled at several levels. This includes on any service or on a specific namespace.

With two different modes of operation, tenant isolation, flexibility of plugins, and tailored security at any level, the ability of a developer to deploy and manage applications with the right functionality and permissioned access is greatly increased.

The Next-gen Platform

Hyperledger FireFly v1.0 was a welcomed addition to the blockchain developer’s toolkit. It brought to blockchain the convenience of a rich middleware stack common in the Web 2.0 space.

With the new release, Hyperledger FireFly is positioning enterprises to harness the benefits of both public and private blockchain technologies. It gives developers the ability to quickly launch multiple applications, tailor each to the desired business logic and security requirements—all while providing a gateway into the wider world of web3.

Hyperledger FireFly 1.1 is another step toward bringing the Enterprise closer to realizing the full potential of web3—both with permissioned chains and connections to public ecosystems. If that’s something you’re interested in, we invite you to come be part of our community. You can learn more in the FireFly docs and download the CLI on the FireFly Github. If you have any questions, find us in the FireFly channel on the Hyperledger Discord.

Want to influence the metaverse? See you at Hyperledger Global Forum

By David Treat, Senior Managing Director - Global Metaverse Continuum Business Group & Blockchain Lead, Accenture and Hyperledger Foundation Governing Board Chair Blog, Hyperledger Global Forum

I first entered the metaverse in 1992 when I was young.

My cousin had lent me his copy of Snow Crash, where Neal Stephenson coined the term that now permeates our headlines. In the book, he describes a profoundly mature metaverse, filled with elaborate systems and cultures.

That vision stuck with me like a Kourier harpoon to a Deliverator door. Thirty years later, we are finally bringing the metaverse to life. Today, however, I see things differently, especially as I look ahead to Hyperledger Global Forum next week.

My vision for the metaverse is one of responsibility. Because we are not only the ones exploring the metaverse—we are helping to build it. The Metaverse is the Next Evolution of the Internet. At Accenture, we think of the metaverse as a continuum: a spectrum of digitally enhanced worlds, experiences and business models poised to transform the next 10 years. It’s set to change every aspect of business, from payments and customer experience to manufacturing and supply chains.

But all this relies on one thing: trust. Adoption and acceptance hinge on our ability to get it right. That means we need to design the metaverse with responsibility at the core. Trust is contingent on safety, privacy, security, sustainability, equity, inclusion, accessibility, well being and more.

I am excited that our Hyperledger community will be at the forefront of shaping the metaverse as the next evolution of the Internet. Hyperledger Global Forum creates a unique opportunity for us to come together and explore the opportunities ahead of us. And as the global chair of the foundation, my goal is to collaborate with all of your to design a responsible metaverse.

Whether you specialize in blockchain or not, I firmly believe this is a must-attend event for anyone who wants to carve out their place in the creation of the metaverse. We welcome you to stop by the Accenture booth in the Expo area, where our Metaverse Continuum team and Hyperledger project maintainers will be showcasing some of our solutions and eager to explore what this new future means for you and your business.

The work begins now

When a friend asks Hiro, the main character of Snow Crash, whether he won a swordfight in the metaverse, he responds:

“Of course. […] I’m the greatest sword fighter in the world.”

“And you wrote the software,” the friend chides.

“Yeah. That, too,” he concedes.

Developer showcase series: Jason Sherman, Developer at Energy & Mines Digital Trust, Government of British Columbia

By Hyperledger Blog, Climate, Developer Showcase, Hyperledger Aries, Hyperledger Indy, Identity

Back to our Developer Showcase Series to learn what developers in the real world are doing with Hyperledger technologies. Next up is Jason Sherman, Developer at Energy & Mines Digital Trust, Government of British Columbia’s Ministry of Energy, Mines and Low Carbon Innovation.

Give a bit of background on what you’re working on and how you got into blockchain

Energy & Mines Digital Trust (EMDT) is a pilot project enabling a collaborative digital ecosystem between the B.C. government, natural resource companies, and organizations around the world, making it simpler and more secure to share sustainability data. I am currently working on EMDT’s technology, called Traction. Traction is basically a layer above Hyperledger Aries Cloud Agent Python (ACA-Py) that enables the Government of British Columbia to use our technology for line of business applications. This allows the government to onboard into the world of digital credentials easily, and to track their business data with their credential and presentation exchanges.

What Hyperledger frameworks or tools are you using in your projects? Any new developments to share? Can you sum up your experience with Hyperledger?

We are using Hyperledger Aries Cloud Agent Python (ACA-Py) and Hyperledger Indy. Using Hyperledger frameworks has increased Traction’s interoperability, making it possible to incorporate a broader range of participants, tools, and technologies into the digital ecosystem EMDT is coordinating. We’re using Hyperledger’s open-source software to accelerate the Government of B.C.’s ability to adopt these tools. My experience with Hyperledger technologies is that things change quickly! And any problem or use case I identify is usually already being addressed.

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

I think the Hyperledger Foundation should focus on multiple ledger support (which is already underway) and onboarding users (not developers) of the implemented technology.

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

There is a very steep learning curve, but it’s extremely worthwhile. You will very quickly identify areas where the technology could benefit your clients.

As Hyperledger’s projects continue to mature, what do you see as the most interesting technologies, apps, or use cases coming out as a result?

I am interested in the ability for Hyperledger projects to enable more automated business flows using truly trusted and tamper-proof data. The number of personnel hours that can be saved just through automated conversation and interchange of data programmatically is massive.

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

I am hopeful that blockchain has the potential to improve trust between businesses. By exchanging information using blockchain technology and digital credentials, the validity and origin of the credential can always be verified, and businesses can proceed with their interactions confidently.

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

I would hope to see blockchain as a viable and easily selected technology, along the lines of Postgresql or MongoDb. I would hope that blockchain could be adopted as a mainstream technology that development teams can look at as a solution to solve their problems.

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

Your code isn’t precious.

What technology could you not live without?

Plumbing.
