Meet the TSC: Dan Middleton, Intel

By | Blog, Hyperledger Sawtooth

Back to our blog series that focuses on the motivations and backgrounds of the individuals that make up Hyperledger’s Technical Steering Committee (TSC). The TSC is a group of community-elected developers drawn from a pool of active participants and is a core element of Hyperledger’s Open Governance model. The TSC is responsible for all technical decisions – from which features to add, how to add them and when, among others.

Now let’s introduce the next Hyperledger TSC member, Dan Middleton from Intel. Let’s see what he had to say about Hyperledger, his role in the TSC and the community!

Describe your current role, background and why you wanted to be a part of the Hyperledger TSC?

My background is in distributed systems and applied cryptography with a particular interest in anonymous credentials. I’ve spent many years working across the boundary of research and commercialization. Currently I’m Head of Technology for Blockchain at Intel.

Being a part of the TSC is a great opportunity to be directly involved in this new and interesting field. I get to work alongside bright people with diverse technical views and see their approaches to the challenges we face.

Dan Middleton, Head of Technology for Intel’s Blockchain and Distributed Ledger program & maintainer of Hyperledger Sawtooth

How are you or your company currently using Hyperledger technologies or how do you plan to?

Intel is using Hyperledger Sawtooth in a number of internal and external engagements.

I’m personally quite interested in Supply Chain applications of blockchain. I’m really proud of work from other committers on this latest addition to Sawtooth’s capabilities.

It’s going to let people automatically add telemetry to records and provide provenance for anything that needs to be tracked (food, software, hardware, etc.). That aspect of traceability is one of the strengths of blockchain I’d like to see tested in the market.

It’s inspired by the case study that Intel previously contributed:

What are the benefits of Hyperledger’s open governance model?

Transparency drives a lot of really good behaviors. Decision making is all in the open and it’s clear for anyone who’s interested to see and participate in how the technology is built. (It’s also an interesting parallel with operating distributed ledgers).

What’s the most important technical milestone for Hyperledger to reach by the end of 2017?

There’s a number of important technical milestones for each project and workgroup under the Hyperledger Umbrella. I’m focused on the Sawtooth 1.0 release and definitions of critical metrics in our new Performance and Scalability workgroup.

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

Pick something that you are passionate about.  

What’s the one thing you hope to accomplish by being a part of Hyperledger’s TSC?

Maintaining the Intellectual honesty of the project. There’s a lot of uncertainty and ignorance about blockchain in the marketplace. We have an opportunity to present a responsible view of the technology so consumers and companies can make rational decisions.

What’s a missing feature or spec that you hope Hyperledger can add in the soon future?

The industry needs a way to meaningfully measure the performance of blockchains. Metrics designed for monolithic systems will not help people make good decisions about blockchain platforms where availability and integrity features are paramount. The work we are starting in the Perf. & Scalability WG should arrive at useful measures that reflect the unique aspects of blockchains.

What’s the biggest struggle or challenge you see Hyperledger having to overcome?

Hyperledger is NOT a single ledger and is not a single project but this is immediately confusing to everyone on their first encounter with the name. As an umbrella, Hyperledger encompasses a wide range of projects each with a unique contribution to the field. Advertising the full breadth of work here is a constant challenge.

Todd McDonald is the co-founder and head of product at R3. He also serves on the Hyperledger Governing Board. Todd believes the Hyperledger community brings a lot of value with its open culture, network and contributions from members.

Blockchain can drastically change not only how banks and financial institutions do business, but how their customers interact, according to Todd. It can make business processes more secure and more efficient at much lower cost.

It comes down to different actors being more comfortable with moving from perception to a shared truth. R3 is very excited to see how the broader Hyperledger community can advance that.

Q&A: Does blockchain alleviate security concerns or create new challenges?

By | Blog

According to some, blockchain is one of the hottest and most intriguing technologies currently in the market. Similar to the rising of the internet, blockchain could potentially disrupt multiple industries, including financial services. This Thursday, October 19 at Sibos in Toronto, Hyperledger’s Security Maven Dave Huseby will be moderating a panel “Does Blockchain technology alleviate security concerns or create new challenges?” During this session, experts will explore whether the shared nature of blockchain helps or hinders security.

We developed a Q&A with Dave to go over some security questions related to blockchain in advance of the panel. Let’s get to it!

What are the cyber-security concerns that you are noticing today?

Integrating with existing systems, cryptographic key material management,  and providing the required network quality of service connecting blockchain members are the greatest cyber-security concerns I am noticing today.  Any organization applying blockchain technology to an existing process almost certainly has existing systems that chaincode/smart contracts will have to interact with.  Building proper oracles to ensure execution of smart contracts is crucial.  Also making sure that all cryptographic key material is properly stored and handled is of great concern.  The entire blockchain security rests on the assumption that cryptographic keys will be secured properly.  And lastly, since most consensus algorithms are latency sensitive, it is also very important to have the most stable and lowest latency network connections possible. If network interference increases latency, the maximum transaction throughput drops.  One potential denial of service is to prevent consensus from occurring by disrupting the lines of communication. With blockchains, extra care of network connections is needed.

How do you think blockchain could disrupt multiple industries and which industries?

Workload management services (e.g. batch processing, batch reconciliation, etc) is one industry that will likely change.  Traditionally, a batch process would be run at the end of each day to process the incoming data and update the stored data in a system.  With blockchains we gain real-time transaction processing, as they are created. With proper business process modeling, batch processing can be eliminated.

I also think we will see blockchains creating an unprecedented level of cooperation on market-wide management between market or consortia members.  Markets where aggregate numbers are used to manage quotas are a good example.  Commercial harvesting of natural resources, humanitarian aid distribution, and a whole host of other systems could all benefit from using a blockchain to track market-wide numbers for management purposes.

Do you think the nature of blockchain will help or hinder security?

It eliminates a lot of security related failure modes (i.e. database sync, siloing of data, etc) but also creates a whole new set of challenges around cryptographic key material management as well as getting integrating blockchains with external systems and other organizations on the blockchain.  Good blockchain security requires the enthusiastic cooperation of multiple IT departments to get things secured correctly.  So overall, I would say that blockchains are a net improvement in security but there are certainly some new challenges that will be new to most organizations.

You have said before you believe security is a people issue, not a technology issue.  Can you elaborate on that and how, if at all, blockchain would change that?

There is an old adage in computer science that goes: even if we design and build the perfect computer system, if you put garbage into it, you will get garbage out. Blockchains don’t change that at all. People and computer-human interfaces are still the dominant factor in the overall security of a blockchain network. It all boils down to the fact that blockchains are distributed systems made up of computers that need to be secured by humans.  With permissioned blockchains, humans are responsible for managing the membership of users and their capabilities.  They are also responsible for deploying the chaincode/smart contracts and also manage the cryptographic key material.  The cryptography and algorithmic design of blockchains is sound and if something goes wrong it is most likely because somebody made a mistake.

If there’s one thing people should understand about security and blockchain at this point in the maturation of the technology, what is it?

A lot of the security techniques and best practices we developed around running web services and distributed business services still apply.  Most of what we already know applies directly to securing the different pieces of distributed ledgers.  The techniques developed from decades of experience security N-tier online services apply to blockchains as well.  

Transactions get proposed by users through a networked API; think of that as analogous to the front-end server in a three-tier web site architecture.  The blockchain API performs the initial validation of the transaction and verifies that the proper credentials have been presented by the transaction proposer.  The transaction then gets forwarded to a peer for validation and endorsement.  To continue the analogy, think of the blockchain peer as being like the web application server, because it also handles executing smart contracts.  Once the transaction is endorsed and the smart contract executed, the transaction moves on to being ordered and recorded in the next block in the blockchain.  That is very similar to how web application state is recorded in a back-end database cluster.

The point of this analogy is to show that blockchains don’t have drastically different security requirements.  The one area that does require some extra attention is around the protection of the cryptographic key materials.  Special care must also be taken to ensure that the consensus part of the distributed ledger operates on network connections with the lowest latency and highest quality of service as possible.  This is because many of the consensus algorithms are latency sensitive and the upper bound on their transaction rate is tied to the overall system latency.

Hyperledger Gets Cozy With Quilt

By | Blog

We’re thrilled to welcome yet another project under Hyperledger, Quilt. Hyperledger Quilt started around 18 months ago and is a Java implementation of the Interledger protocol. Interledger, also known as ILP, is a protocol for making transactions across ledgers. The protocol’s standards and specifications are being defined by the open source community under the World Wide Web Consortium umbrella. With the addition of Quilt to Hyperledger, the Linux Foundation now hosts both the Java (Quilt) and JavaScript (Interledger.js) Interledger implementations. The JS Foundation welcomed Interledger.js in 2016.

As an open consortium, Hyperledger incubates a range of business blockchain technologies, including distributed ledger frameworks, smart contract engines, client libraries, graphical interfaces, utility libraries and sample applications. Quilt is the latest project to join this vast community.

What is Hyperledger Quilt?

Hyperledger Quilt offers interoperability between ledger systems by implementing ILP, which is primarily a payments protocol and is designed to transfer value across systems – both distributed ledgers and non-distributed ledgers. It is a simple protocol that establishes a global namespace for accounts, as well as, a protocol for synchronized atomic swaps between different systems.

Why Quilt?

Ledger systems today are siloed and disconnected. Transfers of value are relatively easy within one country, or if the sender and recipient have accounts on the same network or ledger. But sending value to someone on a different network or ledger is complex and often impractical. Where connections between ledgers do exist, they are manual, slow or expensive.

The Interledger protocol is based on concepts dating back to the 1970s and 1980s, but it took the advent of Bitcoin and the global blockchain movement to make the world realize that money and value transfers could be reinvented with Internet based technologies.

Internet protocols enable information to be packetized, routed and delivered over communication networks. With ILP, money and other forms of value can be packetized, routed and delivered over payment networks and ledgers. Hyperledger Quilt is an enterprise grade implementation of the protocol, developed in Java, and providing libraries and reference implementations of the core Interledger components and in time ledger integrations for other Hyperledger projects.

Technical Details of Quilt

The idea is that Quilt will become a ledger interoperability solution for Hyperledger projects. This will enable Hyperledger members’ distributed ledger solutions, financial institutions’ private ledgers, IoT companies’ wallets, and supply chain systems to connect with one another to perform distributed atomic transactions.

By implementing the Interledger protocol, Quilt provides:

  • A set of rules for enabling ledger interoperability with basic escrow semantics
  • A standard for a ledger-independent address format and data packet format that will enable connectors to route payments
  • A framework for designing higher level use-case-specific protocols

Who will work on Quilt?

Everis, NTT DATA and Ripple are committing full-time engineering resources to ensure the success of this project. The main contributors will include Takahiro Inaba (NTT DATA), Adrian Hope-Bailie (Ripple) and Isaac Arruebarrena (Everis, an NTT DATA Company).

Many other members have already expressed interest in backing the development of Quilt’s Java implementation. This team will seek to work with the other Hyperledger projects in order to find ways to enable ledger interoperability across Hyperledger’s DLT solutions and institutions’ centralised ledgers. Other engineers from NTT DATA, Everis and Ripple will also contribute to the project over time. Members of the Interledger Payments Community Group have also shown interest in contributing to the development of this ILP implementation.

Getting started with Quilt

There will be repositories on GitHub to manage Quilt resources – they will become available over the next several weeks. You can watch for them here: hyperledger/quilt and hyperledger/quilt-crypto-conditions.

Quilt is an exciting addition for the Hyperledger community.  As always, we encourage developers to join our efforts on Quilt as well as other projects, via github, Rocket.Chat, the wiki or the mailing lists.

Meet the TSC: Mic Bowman, Intel

By | Blog

We return to our blog series that focuses on the motivations and backgrounds of the individuals that make up Hyperledger’s Technical Steering Committee (TSC). The TSC is a group of community-elected developers drawn from a pool of active participants and is a core element of Hyperledger’s Open Governance model. The TSC is responsible for all technical decisions – from which features to add, how to add them and when, among others.

Now let’s introduce the next Hyperledger TSC member, Mic Bowman from Intel. Let’s see what he had to say about Hyperledger, his role in the TSC and the community!

Describe your current role, background and why you wanted to be a part of the Hyperledger TSC?

I lead the distributed ledgers research group in Intel Labs, focused on the use of advanced processor technologies for improving the scalability, resiliency, and confidentiality of blockchain technologies. The Hyperledger Working Group provides a channel for delivering new blockchain technologies to the broadest possible base of enterprise users.

Mic Bowman, principal engineer & head of the distributed ledger research group at Intel

What are the benefits of Hyperledger’s open governance model?

The open governance model ensures that interests of the community supersede the interests of any individual organization. It fosters an environment where companies can work together to deliver common building-block technologies that enable lost-cost experimentation and ultimately deployment of enterprise blockchain applications.

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

Blockchain is not one technology. It is an approach to solving problems of decentralized trust. To be successful, start with the problem you want to solve, not the technology you want use to solve it.

Developer Showcase Series: Vitalii Demianets, Norbloc

By | Blog

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

Isolate yourself from the hype.

Analyze why do you want to start working with blockchain. The ideal case would be that you already have a task on hands which requires decentralized communication and/or storage media without single point of trust.

As soon as you understand why _you_ need the blockchain…

…ride the hype!

Use blockchain as a door-opener to promote yourself and your project. A lot of huge companies and enthusiastic individuals are looking into the technology right now. They are happy to talk to you about blockchain even if they are not interested in your project… yet.

But in all cases if you are in a corporate environment, first make sure a blockchain implementation is the most applicable one for the problem you are trying to solve!

Vitalii Demianets, co-founder & lead developer, Norbloc

Give a bit of background on what you’re working on, and let us know what was it that made you want to get into blockchain?

Currently at Norbloc, I am the architect of the KYC solution for banks. We are building a system which allows to share personal/corporate client data and verification stamps between banks in a heavily regulated environment where data sharing between parties is subject to stringent laws and limitations.

Obviously we need a distributed permissioned database for such a solution, and we have chosen blockchain as a best implementation of such a database which also brings in a couple of additional features, like elimination of the single central point of trust and independent reliable timestamping. No other distributed database suits our needs.

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

Key management solution.

Decentralized key management is a much desired feature which a lot of projects are asking for. All current solutions require either a separate app installed on the customer’s smartphone or putting trust into some form of centralized key management solution (e.g. Amazon KMS).

Personally I believe that decentralized trustless nature of blockchain is a perfect environment for the decentralized key management. It allows for a consensus on which keys are considered valid (i.e. revocation problem) to be achieved in a natural way, as blockchain is built on consensus. There are a couple of technical obstacles still in the way of building a key management system on blockchain, but I believe they can be solved.

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

Application: Self-sovereign digital ID.

The world needs this application, so many areas of human development are stagnating form the lack of universally accepted ID which is not dependent on a stamp of approval from at times inefficient or even non-existent governmental systems.

National borders are making isolated silos preventing growth. Also, currently we have a lot of isolated IDs: personal identity, educational certificates, skill assessments, credit ratings, all regulated separately and sometimes those regulations are contradictory.

I believe it’s time to interconnect those silos and put the owner of the ID at the center of the equation, always at control of his/her data and access to it by third parties. That is exactly the direction we are working towards with our KYC platform but we could certainly use a similar effort for personal IDs as these constitute a small but integral part of KYC efforts as well.

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

  1. Just do it.
  2. Use Git.
  3. No optimization without profiling. No premature optimization.


Meet the TSC: Chris Ferris, IBM

By | Blog

Describe your current role, background and why you wanted to be a part of the Hyperledger TSC?

I’m IBM’s CTO for Open Technology and as such, responsible for all of IBM’s strategic open source initiatives. Blockchain technology is one of the most important new technology directions for IBM and given our long standing preference for open technology under open governance, I worked closely with the Linux Foundation to help make Hyperledger a reality. I’ve served on the TSC since its inception and had the honor of being elected to serve as its chair twice by the organization’s technical community. As to why I want to serve on the TSC, basically to help the community deliver a consistent experience as possible amongst the various projects and to help the various project communities find opportunity to collaborate with each other.

Chris Ferris, CTO for Open Technology at IBM

How are you or your company currently using Hyperledger technologies or how do you plan to?

IBM has offerings and solutions based on Hyperledger Fabric and Composer – two of the Hyperledger projects that IBM incubated.

What are the benefits of Hyperledger’s open governance model?

IBM believes strongly that open source should be developed, where possible, under open governance. We’ve worked closely with the Linux Foundation and other open source foundations to help move key projects in this direction. The benefits of open governance are myriad, but important characteristics are

– eliminates single vendor/individual control over a project’s evolution,
– greater potential for diversity of community and ecosystem growth
– greater potential for sustained success
– collectively, diverse communities under open governance tend to innovate at a greater pace than single vendor/individual projects

What’s the most important technical milestone for Hyperledger to reach by the end of 2017?

I’d like to see us make greater strides towards integration and interoperability between projects.

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

Get involved in one of the Hyperledger hosted projects 😉 In all seriousness, the best way to get involved in any open source initiative is to start at the edges and work your way in. Start by fixing bugs and helping to improve documentation as these are often the underserved aspects of any project and help in burning down any technical debt is always welcome. As you become more comfortable, start thinking about taking on more work, such as working on a new feature with others in the community, etc.

What’s the one thing you hope to accomplish by being a part of Hyperledger’s TSC?

The continued success of Hyperledger and its hosted projects.

What’s a missing feature or spec that you hope Hyperledger can add in the soon future?

I think we need to devote more to thinking about how the various projects might one day interoperate and/or compose with one another. I also think that this needs to be more than merely an academic exercise. It needs to be based in real, working code with the implementation support of multiple of the various projects.

What’s the biggest struggle or challenge you see Hyperledger having to overcome?

Generally, the community’s greatest challenge is working across project boundaries. It is tough when the development community around a given project serves as the foundation for vendor offerings as there are always demands on people’s time and resource expenditures. Making time for such interactions is critically important and often yields the best results – but this can be a tough sell.

[VIDEO] Hyperledger Interviews Justin Newton, Netki

By | Blog

Justin Newton is the CEO and co-founder of Netki. Netki produces standards for the blockchain ecosystem and Justin believes it’s important that the standards they deliver to other blockchains can be used universally across all of them. Being part of Hyperledger helps create that continuity across the different blockchains that they work on.

Advancements in blockchain technology will dramatically change the way most businesses operate in the future. Much like how the internet started out doing things we already did like long distance communication but in a lower cost way, blockchain’s first and main focus has been on increasing efficiency and lowering costs like in payments or sharing information

The bigger promise of blockchain for Justin is that it is an open network for use and innovation around financial services, value transfer, and data ownership, which will lead to dramatic and sweeping changes across all industries as the technologies mature and they become more scalable.

Netki decided to get involved with Hyperledger because it brought together two important areas for development of blockchain: one is the focus on open source and open standards, and two is it provides a strong and predictable governance model around that open source project. Hyperledger gives a stable and predictable path for the development of the technology and a governance process that allows enterprises to feel comfortable with the go forward path. Netki can work with other technologists to help create best of breed standards for blockchain.
