The yellow pages of blockchain has arrived: Networks are now visible to the world

In the 1830s the first Yellow Pages emerged as an organized directory of businesses. This had a profound effect on commerce and is an often-overlooked key contribution to the Industrial Revolution. Simply put, the Yellow Pages put businesses on the map and made them known to the world. Without it, a business was hidden and only visible to those who knew about it via invitation.

Similarly, in the late 1990s ICANN became the coordinator of several directories including the Domain Name System (DNS) that is central to launching the internet and the world wide web, by uniquely listing businesses names and address, thereby transforming them to publicly addressable and digitally interactable entities. We think blockchain is the third major wave of network technology (phone, internet, blockchain). But we were missing something, up until now.

Today, I am proud and excited to announce that we have joined the HACERA Unbounded Registry as a founding member. As the number of blockchain consortiums, networks and applications continues to grow we need a means to list them and make them known to the world, in order to unleash the power of blockchain. The Unbounded Registry, built on blockchain technology, provides a decentralized means to register, look up, join and transact across a variety of blockchain solutions, built to interoperate with all of today’s popular distributed ledger technologies, including The Linux Foundation’s Hyperledger Fabric, Hyperledger Sawtooth, EEA Quorum, Stellar Network and more.

What makes a private network private, or a public network public? Well, most private networks are unlisted. Unbounded gives these network solutions a change to be in the “yellow pages of blockchain,” and be publicly visible. As a founding member of several consortiums and a technology provider for others, we are frequently asked questions such as, “As a supplier, how can I join the TradeLens trade digitization blockchain,” and “What capabilities does LedgerConnect provide?”. . Also, “Is the True Tickets network running, and how do I list a new event?” — by the way… the answer is yes, it’s running. With Unbounded, a solution user is one step closer to answering their questions themselves.

Since IBM began our blockchain journey, we have been committed to the development and use of open technologies. We realized from the start that you cannot do blockchain on your own; you need a vibrant community and ecosystem of like-minded innovators who share the vision of helping to transform the way companies conduct business in the global economy. We initially joined Hyperledger, and contributed the initial code for Fabric, to collaborate on blockchain for business, then the Sovrin Foundation for decentralized identity and we have also participated in the Stellar network for global payments.

IBM and HACERA have been working closely on blockchain technology for a while. HACERA was one of the first members of the IBM Blockchain ecosystem — going back to 2016 — including the HACERA and IBM release-managed Hyperledger Fabric 1.0 a year ago.
We see HACERA’s Unbounded Registry providing several key capabilities that addressed these common problems:

  • Reserved naming for networks, applications and consortiums.
  • The discoverability of blockchain networks and applications.
  • catalogue of domain-specific functions and services.
  • An independent, open and shared blockchain backed platform to help us all with bootstrapping, launching and growing our communities.

By working with HACERA and other members of Unbounded Registry, we see a future where consumers and providers of blockchain services will be able to discover each other and begin transacting in a more secure way and where technology providers and consumers can innovate and integrate to create limitless and unbounded possibilities.

Blockchain — The New Black. What about Enterprise Security?

If blockchain, the distributed ledger (DLT) underlying bitcoin, is the new black, it is time to ask: is it secure? We know it is more valuable than the currency it supports. Enterprises start to put distributed ledger technology into practice. It’s important to understand the security implications for the industry. This session will look at public vs. private blockchains and lessons learned for enterprises.

How the HACERA Team Won Two Awards at Consensus 2017 Building Blocks Hackathon

Lead by its CEO, Jonathan Levi, HACERA’s team of experienced technical innovators demonstrated their ability to integrate multiple blockchain technologies overnight and to win awards from both the Enterprise Ethereum Alliance and Microsoft. Their Dutchess application is a secure decentralized version of Chess on the blockchain that allows players to use ETH to pay for an unfair advantage in a sealed-bid Dutch auction. The entry highlights HACERA’s approach to integrating multiple permissioned & public blockchains.

The HACERA project incorporated:

  • Public Ethereum accounts to transfer money
  • Solidity for Business Logic and Smart Contracts
  • Quorum (JP Morgan’s fork of Ethereum) for encrypting transaction payloads
  • Sovrin for registering identity tokens and creating a permissioned and public identity chain
  • Hyperledger Sawtooth to provide a Trusted Execution Environment (TEE) for security and auditability
  • HACERA’s Self-Sovereign ID implementation (using Decentralized Identifiers)
  • Microsoft Azure cloud deployment

The result was a mini HACERA-like workflow that provides a secure, auditable, privacy preserving solution that prevents impersonation (relying on self-sovereign identity) and offers a non-repudiation guarantee – with a playable fun game of Chess on a blockchain.

With this project, HACERA was able to solve a complex problem while touting its ability to provide tools that work on top of different blockchains, along with their expertise helping customers choose the right technology for the task at hand.

The HACERA team attributes their success to their broad expertise in the blockchain space (including early work with Bitcoin and Ethereum) and their ability to solve many complex use-cases with blockchain technology. In particular, Jonathan Levi has worked on numerous business use-cases in his collaboration with organizations from many different sectors in his capacity as Hyperledger Fabric’s Release Manager.

It is extremely rare to find a team so versatile and experienced in the blockchain space that it can identify the best technological tools and integrate them quickly to achieve objectives. Many teams tend to rely upon the small set of technologies they are familiar with, even when they are not the best technologies for the job. The HACERA team proved their versatility along with their ability to think different, in combining multiple technologies to create a unified and secure end-to-end workflow.

“One big challenge of the Dutchess project was connecting public and permissioned blockchains reliably and securely. There are many use-cases where parties need to interoperate and collaborate, and move data reliably and securely, both in terms of access control management (who can see what, who can do what). Service availability is also a major consideration, so users are not blocked or delayed at any point in the workflow. There is huge value in combining several technologies to meet the security requirements and challenges posed by use-cases that involve several parties. We think this is what the judges appreciated most by our Dutchess application and this is our fundamental philosophy at HACERA,” says Jonathan Levi.

HOW THE DUTCHESS PROJECT AT CONSENSUS 2017 ILLUSTRATES INTEROPERABILITY BETWEEN MULTIPLE BLOCKCHAINS

It is not everyday that one comes across a development team so versatile and experienced in the blockchain space that it is able to recognize that the best technology stack solution to a challenge may not be the stack that the team uses every day. However, this is exactly what the HACERA team, which has been very active on the Hyperledger Fabric project, did when it decided to compete at the 2017 Consensus Building Blocks Hackathon.

Overnight the HACERA team built a project they called Dutchess and won two (!) awards. The Enterprise Ethereum Alliance challenge to “use an Enterprise Ethereum Alliance stack to create a decentralized Dutch auction network with secret bid matching” and the Microsoft challenge to “leverage Microsoft Azure as part of your blockchain project.”

The HACERA team of Jonathan, Sergey, and Michael attributes its success at the hackathon to their broad experience in the blockchain space and their philosophy of focusing on understanding the situation to get the requirements “right” before jumping to propose a solution or a technology stack.

Jonathan Levi, creator of the first Ethereum course at Stanford University, founded HACERA in 2015 to create of the world’s first fully-decentralized system for securing and permissioning blockchains which includes managing the identity of participants (users and devices) and securely sharing sensitive data on blockchains.

There are many lessons that others in the industry can learn from HACERA team’s approach and the Dutchess project. “It is about time we change the mindset that advocates one technology stack as the complete solution for entity”, says Jonathan. “When we examine most real-world use-cases, these days, there are plenty technological solutions at bay. This is why we choose to integrate well, rather than re-invent the wheel.”

The architecture of the Dutchess project illustrates how different blockchain technology stacks can be specific requirements in different parts of an organization, such as finance and IT, while still facilitating interoperability between those stacks within an organization. In the case of the Dutchess, the team used Ethereum for payments, Quorum for encrypting transactions’ payloads, Hyperledger Indy for identity management, and Hyperledger Sawtooth for secure and audible Chess game (simulating a Trusted Execution Environment), and deployed it all on Microsoft Azure.

The actual challenge was working connecting public and permissioned blockchains reliably and securely. There are many use-cases where parties need to interoperate and collaborate, move data doing it reliably and securely, both in terms of access control management (who can see what, who can do what) and in terms of service availability – so that users are not blocked at any point in the workflow. “There is a huge value in being able to securely combine several technology stacks to meet the security requirements and challenges posed by typical use-cases that involve several parties. This is what the judges appreciated most in Dutchess, and is our philosophy in HACERA”, said Jonathan.
