Bruce Schneier reconsiders the definition of trust in his keynote presentation from the recent Hyperledger Global Forum.

Blockchains have to be trusted in order for them to succeed, and public blockchains can cause problems you may not think about, according to Bruce Schneier, a fellow and lecturer at the Harvard Kennedy School, in his keynote address at December’s Hyperledger Global Forum on “Security, Trust and Blockchain.”

Schneier began his talk by citing a quote from Bitcoin’s anonymous developer, Satoshi Nakamoto, who said “We have proposed a system for electronic transaction without relying on trust.”

“That’s just not true,’’ Schneier said. “Bitcoin is not a system that doesn’t rely on trust.” It eliminates certain trust intermediaries, but you have to somehow trust Bitcoin, he noted. Generally speaking, the Bitcoin system changes the nature of trust.

Schneier called himself a big fan of “systems thinking,” which is what the issue boils down to, he said. This is something that is in too short supply in the tech world right now,’’ he maintained, and “we need a lot more of it.”

Trust relationships

Schneier’s talk focused on the data structures and protocols that make up a public blockchain. He called private blockchains “100 percent uninteresting,” explaining that they’re easy to create and secure, they don’t need any special properties, and they’ve been around for years.

Public blockchains are what’s new, he noted. They have three elements that make them work:

  • The ledger, which is the record of what happened and in what order
  • The consensus algorithm, which ensures all copies of the ledger are the same
  • The token, which is the currency

All the pieces fit together as a single system, and whether they can achieve anything gets back to the issue of trust, he said.

When he reads some of the comments of blockchain enthusiasts, such as “in code we trust,” “in math we trust,” and “in crypto we trust,” Schneier believes they have “an unnaturally narrow definition of trust.”

Trust as a verification mechanism is true, but you cannot replace trust with verification, he stated. For example, Schneier recounted waking up in his hotel room and trusting that the keys worked, naturally trusting the people who prepared his breakfast, and trusting that all the people he encountered on his way to the forum would not attack him.

“Trust is essential to society,’’ he said. “Humans as a species, are very trusting.” And, he continued, “The fact that we don’t think about it most of the time is a measure that trust works.”

Trust architectures

Schneier cited the book, Blockchain and The New Architecture of Trust, by Kevin Werbach, in which the author outlines the following four different trust architectures:

  • Peer-to-peer trust
  • Leviathan trust, which is institutional and involves contracts
  • Intermediary trust, like PayPal or credit cards that make a transaction work
  • Distributed trust, which is what blockchain enables — an emergent trust in the system without any individuals in the system trusting each other

“Blockchain shifts trust in people and institutions to trust in technology,” Schneier said. This means having to trust the cryptography, the software, the computers, the network, and the people who are making all of this work, he said. Along the way there are a lot of single points of failure, and if a blockchain gets hacked or you forget your credentials, you lose your money.

It comes down to the question of who you would rather trust: a human legal system or the details of computer code? Schneier said that, in a lot of ways, trusting technology is a lot harder than trusting people. Institutional trust is still needed, he said, because you still need people to be responsible for these systems.

Bitcoin might theoretically be based on distributed trust, “but practically, that’s just not true.” You have to trust the wallets and the exchanges, and there’s not many of either, as well as the software and the operating systems and computers that everything the blockchain runs on, he said.

“If you think about the attacks on bitcoin, this is where they are – they don’t go against the math, they go against the computer science.” There is always a need for governance outside the system, and a need to override the rules and make changes when necessary, he stressed.

Blockchain systems will always have to exist with other more conventional systems and Bitcoin will always need to interoperate with the rest of the financial world, he said. “That interface, with its laws and norms, often requires breaking the trust architecture of the blockchain system.” This means you can’t have a Bitcoin system where transactions clear immediately work with a credit card system where transactions clear in three days, he said.

A key feature of trust is that if the transaction goes bad or if your credentials are stolen, you get your money back, Schneier said. At the same time, trust is expensive. The reason people don’t use Bitcoin is because they don’t trust it, not because of the cryptography or the protocols, he maintained.

Human element

“A currency that is volatile is not particularly trustworthy,’’ he said. “That’s the human way of looking at trust.” Ethereum is an interesting example of how trust is working. “The fact that we have hard forks means we still need trusted people. This trust is a lot more complicated than transaction verification.” People will choose Bitcoin and an exchange or wallet based on reputation, he said, whether it’s something they read or a recommendation from a friend.

He concluded his talk by noting that trust is much more social; a human thing.

“So truly understanding this requires systems thinking. I really want everybody who designs and implements blockchains to understand the systems they’re working in,” Schneier said, not just the technology aspect, but the social parts and how they work. He suggested people start by asking whether they need a public blockchain?

“I think the answer is almost certainly no, and by this I’m answering the security question, not the marketing question,’’ he said. “Blockchains likely don’t solve the security problems you think they solve,” and they cause other problems you don’t think about, like inefficiencies, especially scaling. Schneier said there are almost always simpler and better ways to achieve the same security properties.

He advised the audience to look at the trust architecture and whether the blockchain “will change it in any meaningful way or does it just shift it around to no real effect?” He also asked them to think about whether the blockchain replaces trust verification and what aspects of trust does it try to fix and fail?

“Does it strengthen existing trust relationships, or does it go against them? Are the trust intermediaries of the new architecture better or worse than the old arch? How can trust be abused in the new system?” he said. “Is it better or worse than the old system and, lastly, what would the same system look like if it didn’t use blockchain?”

In most cases, Schneier said, his guess is that people will choose solutions that don’t use public blockchains because of all the problems they bring. “I’m not saying that they’re useless,” he added, “but I have yet to find an example where the things they do are worth the problems they bring.”

Get the latest on Hyperledger from Brian Behlendorf.

Brian Behlendorf has been heading the Hyperledger project since the early days. We sat down with him at Open Source Summit to get an update on the Hyperledger project.

Hyperledger has grown in a way that mirrors the growth of the blockchain industry. “When we started, all the excitement was around bitcoin,” said Brian Behlendorf,  Executive Director of Hyperledger. Initially, it was more about moving money around. But the industry started to go beyond that and started to see if it “could be used as a way to reestablish how trust works on the Internet and, and try to decentralize a lot of things that today with led to being centralized.”

“It might be OK for things like social networks or ride-sharing services to be centralized, but if you are talking about the banking or supply chain, you may not want that to be centralized,” said Behlendorf.

As the industry has evolved around blockchain so did Hyperledger. “We realized pretty early that we needed to be a home for a lot of different ways to build a blockchain. It wasn’t going to be like the Linux kernel project with one singular architecture,” said Behlendorf.

Hyperledger projects

It was going to be more than just one architecture. Today, Hyperledger has 10 different technology projects. Five of those are called frameworks. Two of those frameworks are now production quality, including Hyperledger Fabric and Hyperledger Sawtooth.

“These two frameworks now drive about 40 production networks that we see out there and about 60 different vendors, hosts, and other companies building on top of it,” said Behlendorf. “One way we have grown is by growing the commercial ecosystem around this code.”

Hyperledger has created software stacks that organizations like banks run to participate in a blockchain project and a distributed ledger with several of other organizations with whom they want to do business.

Global growth

One region where Hyperledger is witnessing incredible interest is mainland China. “The Chinese government has actually said this is a top-level priority for them, to figure out how to make distributed ledgers work,” said Behlendorf. “About 20 percent of our members come from Chinese companies like Baidu, Tencent, and Huawei. These companies are actually contributing code, which is great to see.”

As the adoption of Hyperledger projects is growing, the organization is also working on creating training and education courses in partnership with edX to meet this growing demand. Hyperledger also has a technical working group focused on communicating in Chinese with developers who are there to help them get involved with the project.

Hyperledger aims to be a global initiative. “There are a few Silicon Valley companies involved, but it’s New York. It’s London. It’s Singapore. It’s incredibly broad,” said Behlendorf. “That’s been really reassuring because open source is a global phenomenon and really should be about kind of uplifting all regions. So it’s been a great journey.”

Join us Wednesday, September 26, 2018 9:00 a.m. Pacific for an introductory webinar showing how to deploy Hyperledger Fabric.

Deploying a multi-component system like Hyperledger Fabric to production is challenging. Join us Wednesday, September 26, 2018 9:00 a.m. Pacific for an introductory webinar, presented by Alejandro (Sasha) Vicente Grabovetsky and Nicola Paoli of AID:Tech.

Why should you care?

Hyperledger Fabric is rather awesome, but deploying a distributed network has been known to give headaches and even migraines. In this talk, we will not be providing you with a guillotine that forever gets rid of these headaches, but instead we will talk you through some tools that can help you deploy a functioning, production-ready Hyperledger Fabric network on a Kubernetes cluster.

Who should attend?

Ideally, you are a Dev, an Ops or a DevOps interested in learning more about how to deploy Hyperledger Fabric to Kubernetes.

You might know a little bit about Hyperledger Fabric and about Docker containers and Kubernetes. We assume limited knowledge and will do our best to as possible and explain and demystify all the components along the way.

What we will talk about?

In this webinar, we will lower the threshold so that you can deploy your very own Hyperledger Fabric network onto Kubernetes. So what is each of these?

Hyperledger Fabric is a permissioned (unlike the permissionless Ethereum network) framework, allowing you to create consortium Blockchain networks, where one or more organisations share an immutable ledger of records and smart contracts (called “chaincode” in Hyperledger Fabric).

Kubernetes is a platform for deploying microservices (i.e. containerised applications, typically using Docker) applications on a cluster, such that the applications:

  • use fewer resources than when using dedicated (bare metal or virtual) machines for each component,
  • are self-healing, such that failed containers are restarted
  • and are configured in a declarative rather than procedural way, making them robust

We do this by using a set of Helm Charts. Rather than using a monolithic Helm Chart for the whole deployment, we use separate charts for each Hyperledger Fabric component, namely the Certificate Authority, Peer, CouchDB and Orderer. We demonstrate how to get these charts working together to provide a unified blockchain system.

Along the way, we will explain the different concepts you need to understand your Hyperledger Fabric network:

  • What is a Certificate Authority?
  • Why is the network split across Orderers and Peers?
  • And what are CouchDB and Apache Kafka doing in all of this?

We’ll also guide you in the right direction to other resources you can look at to expand your understanding on how Hyperledger Fabric works, including:

  • the official EdX course and our upcoming chapter on Composer,
  • Sasha’s own course on Hyperledger Fabric and Composer, and
  • we will be using the Helm Charts (Kubernetes packages) we created to make our own lives easier.

When and where?

The webinar will be running on Wednesday, September the 26th, 9-10am PDT.

Brian Behlendorf

Brian Behlendorf, Executive Director of the Linux Foundation’s Hyperledger project, has been named one of the top 10 influential voices in the blockchain world by the New York Times.

Brian Behlendorf, Executive Director of the Linux Foundation’s Hyperledger project, has been named one of the top 10 influential voices in the blockchain world, in a New York Times commentary titled “The People Leading the Blockchain Revolution.” Blockchain technologywhich encompasses smart contracts, distributed ledgers, and more—is already transforming contracts, payment processing, asset protection, and supply chain management.

In the article, Behlendorf is credited with driving the evolution and widespread adoption of numerous essential blockchain platforms and tools.

“Mr. Behlendorf has helped bring in other big names who are helping to make Hyperledger the focus of much of the corporate and governmental interest in blockchains today,” the Times reports.

“Hyperledger now oversees several different blockchain projects, but its biggest product is Fabric, which is being used by everyone from Walmart to the Centers for Disease Control and Prevention. Mr. Behlendorf, meanwhile, has tried to make sure the technology has kept its open-source soul even as it has begun to go mainstream” states the article.

Behlendorf is no stranger to protecting the open source soul of major projects or building strong open source communities. He was a primary developer of Apache Web server and a founding member of the Apache Group, which later became the Apache Software Foundation.

“There is exciting stuff going on with blockchain and real-world problems are being solved,” Behlendorf said during a recent keynote address at Token Fest, a leading blockchain exhibition and conference. In his address, he provides details on how Hyperledger’s tools and platforms are being used right now.

Hyperledger

A recent webinar, Get Involved: How to Get Started with Hyperledger Projects, focuses particularly on making Hyperledger projects more approachable.

Few technology trends have as much momentum as blockchain — which is now impacting industries from banking to healthcare. The Linux Foundation’s Hyperledger Project is helping drive this momentum as well as providing leadership around this complex technology, and many people are interested in getting involved. In fact, Hyperledger nearly doubled its membership in 2017 and recently added Deutsche Bank as a new member.  

A recent webinar, Get Involved: How to Get Started with Hyperledger Projects, focuses particularly on making Hyperledger projects more approachable. The free webinar is now available online and is hosted by David Boswell, Director of Ecosystem at Hyperledger and Tracy Kuhrt, Community Architect.

Hyperledger Fabric, Sawtooth, and Iroha

Hyperledger currently consists of 10 open source projects, seven that are in incubation and three that have graduated to active status.  “The three active projects are Hyperledger Fabric, Hyperledger Sawtooth, and Hyperledger Iroha,” said Boswell.

Fabric is a platform for distributed ledger solutions, underpinned by a modular architecture. “One of the major features that Hyperledger Fabric has is a concept called channels. Channels are a private sub-network of communication between two or more specific network members for the purpose of conducting private and confidential transactions.”

According to the website, Hyperledger Iroha is designed to be easy to incorporate into infrastructural projects requiring distributed ledger technology. It features simple construction, with emphasis on mobile application development.

Hyperledger Sawtooth is a modular platform for building, deploying, and running distributed ledgers, and you can find out more about it in this post.  One of the main attractions Sawtooth offers is “dynamic consensus.”

“This allows you to change the consensus mechanism that’s being used on the fly via a transaction, and this transaction, like other transactions, gets stored on the blockchain,” said Boswell. “With Hyperledger Sawtooth, there are ways to explicitly let the network know that you are making changes to the same piece of information across multiple transactions. By being able to provide this explicit knowledge, users are able to update the same piece of information within the same block.”

Sawtooth can also facilitate smart contracts. “You can write your smart contract in a number of different languages, including C++ JavaScript, Go, Java, and Python,” said Boswell. Demonstrations and resources for Sawtooth are available here:

How to contribute to Hyperledger projects

In the webinar, Kuhrt and Boswell explain how you can contribute to Hyperledger projects. “All of our working groups are open to anyone that wants to participate, including the training and education working group,” said Kuhrt. “This particular working group meets on a biweekly basis and is currently working to determine where it can have the greatest impact. I think this is really a great place to get in at the start of something happening.”

What are the first steps if you want to make actual project contributions? “The first step is to explore the contributing guide for a project,” said Kuhrt. “All open source projects have a document at the root of their source directory called contributing, and these guides are really to help you find information about how you’d file a bug, what kind of coding standards are followed by the project, where to find the code, where to look for issues that you might start working with, and requirements for pull requests.”

Now is a great time to learn about Hyperledger and blockchain technology, and you can find out more in the next webinar coming up May 31:

Blockchain

Openness ensures scalability, accessibility, resiliency, and innovation, said Change Healthcare’s Aaron Symanski at Open Source Leadership Summit.

Blockchain technology is heralded to become a broadly disruptive force in the coming years. According to a Forbes story, blockchain is already revolutionizing contracts, payment processing, asset protection, and supply chain management. However, partly due to the industry’s emphasis on records, authentication and people-centric processes, healthcare is predicted to be one of the fields that blockchain will truly transform.

That was the key message at an Open Source Leadership Summit keynote address titled “Blockchain Technology at Change Healthcare” by Aaron Symanski, CTO at Change Healthcare. In his talk, Symanski said that blockchain is already impacting the healthcare system.

Symanski made the point that from the 1960s through now, computers, networks, mobility and automation have driven societal change, and now blockchain is set for disruption. Specifically, he said that blockchain will usher in a healthcare future where information is:

  • Immediately available
  • Identical everywhere it is stored
  • Immutable
  • User-centric and controlled by the contributor

He also emphasized that open source efforts, such as The Linux Foundation’s Hyperledger Project, are driving blockchain forward and are essential. He said that openness ensures scalability, accessibility, resiliency, and innovation. “Participating in The Hyperledger Project has made a lot of sense for us,” Symanski noted. “It protects protocol governance, node management, consensus mechanisms, and more and these are all very important in the healthcare industry.”

Trusted workflow

“Trust is very different in healthcare that it is, in say, financial applications,” he emphasized. “Healthcare is very fragmented, especially in the U.S. What is identity? Who has the right to see records? What portions of the record can a person see?”

Change Healthcare works with Hyperledger Fabric for its blockchain applications, partly because it’s a modular, extensible architecture. It has enabled smart contracts, flexible consensus management, and applicability across industries ranging from insurance to healthcare itself.

“Claims management is one of the first applications that our healthcare network has leveraged blockchain for,” Symanski said. “It helps streamline data and rights management and the platform helps manage visibility and transparency.” Hyperledger Fabric is at the core of the platform that ensures that, say, an insurance provider can process claims with Change Healthcare efficiently.

Symanski emphasized that Change Healthcare is still in the early stages of its planned use cases for blockchain. Indeed, the whole healthcare industry is. According to a report from Frost and Sullivan Research: “At its core, blockchain offers the potential of a shared platform that decentralizes health data, ensuring access control, authenticity, and integrity of protected health information. Further, the blockchain-based distributed network consensus with cryptography techniques provides an additional layer of trust to minimize cybersecurity threats for healthcare IT systems. This never-before blockchain-based trusted workflow with a “single source of truth” presents the healthcare industry with radical new possibilities for outcome-based care delivery and reimbursement models.”

Meanwhile, according to a recent post on the Hyperledger blog, “Hyperledger remains the fastest growing open source project ever hosted by The Linux Foundation.” To find out more about blockchain and Hyperledger, check out the case studies, a webinar, and training resources available from hyperledger.org.
