The Hyperledger team (and 40 of our members!) spent a good amount of time in New York for CoinDesk’s annual Consensus conference last week. It was a great event with tons of excitement and enthusiasm around blockchain and its many applications. Attendees were from all walks of life – from developers to architects to financial services professionals to healthcare specialists to investors – all trying to better understand the best and most practical use cases of the technology.
The event kicked off the weekend before with the Building Blocks Hackathon at 30 Rockefeller where many of the world’s top blockchain developers vied to build the next killer smart contract app. Participants could build on top of any blockchain protocol: bitcoin, Ethereum, Hyperledger or otherwise. And through various sponsor challenges, they were encouraged to leverage the software and support made available by our world-class mentors in order to deliver projects.
Jonathan Levi, an active Hyperledger community member and the founder of HACERA, won 2 hackathon challenges using Hyperledger technology. They won the Enterprise Ethereum Alliance challenge and they were one of the winners of the Microsoft challenge. They called their solution Dutchess – a secure decentralized Chess on the blockchain that allows players to use ETH to pay for an unfair advantage in a sealed-bid Dutch auction. The entry highlighted Jonathan’s and HACERA’s approach of integrating multiple permissioned & public chains.
- Public Ethereum accounts used to transfer money to a sealed-bid Dutch auction
- Confidential transactions using Solidity on Quorum, deployed on Microsoft Azure
- A permissioned and public identity chain (Sovrin) for registering identity tokens
- Hyperledger Indy for implementing secure verifiable claims
- Hyperledger Sawtooth for transaction processing and validation
The result was a mini HACERA-like workflow that provided secure, auditable, privacy preserving, that prevents impersonation, relying on self-sovereign identity and offers a non-repudiation guarantee – with a playable fun game of Chess on a blockchain.
Early Monday, the Hyperledger team then set up shop on the 6th floor of the Marriott Marquis in Times Square. Crowds of attendees stopped by each day to learn more about the technology.
At the booth several member companies gave demos on different Hyperledger projects including Hyperledger Fabric and Hyperledger Iroha. Cloudsoft demonstrated Deploying Hyperledger Fabric on Kubernetes with Cloudsoft AMP. IBM showed Connect a Cloud, connecting organizations together on Hyperledger Fabric using hosted cloud providers of choice. Soramitsu ran a KYC/user identity demo of Hyperledger Iroha/Android app and video, and Byacco, a local digital currency currently in use at University of Aizu in Fukushima, Japan. IntellectEU together with their customer Telindus (Proximus Group) explained streamlined asset transactions through reconciliation, matching and resolution among multiple parties.
Hyperledger also hosted a Roundtable on Monday on its distributed ledger technologies, Hyperledger Sawtooth and Hyperledger Iroha, each technology had end users speak to their different use cases. Kelly Olsen from Intel spoke to Sawtooth and his user, Pokitdok CTO, Ted Tanner weighed in on how they are utilizing Sawtooth in their healthcare blockchain solution. Makoto Takemiya, CEO, co-founder, Soramitsu discussed Hyperledger Iroha as a blockchain framework for mobile applications and Soichiro Takagi, from the Center for Global Communications (GLOCOM), International University of Japan shared his experience with the technology.
In addition to the robust line-up of Hyperledger activities in the main Consensus program and on the show floor, Hyperledger hosted a series of talks that ran all day Monday and Tuesday in the Hyperledger Mini Summit room. Attendees interested in how to best collaborate and get involved in the Hyperledger initiatives and learn where they can provide the most value had their bases covered in Monday’s “Meet the Hyperledger community” sessions. Speakers included the new technical staff, and diverse representation from the Technical Steering and Marketing committees, Governing Board, Identity Working Group and our fearless leader, Brian Behlendorf, Hyperledger’s executive director.
In Tuesday’s Hyperledger Mini Summit sessions, members dove a bit deeper into the impact of blockchain technologies on their businesses with field reports on how they are using Hyperledger to solve their business objectives. Attendees heard technical insights from Norbloc on the KYC process, IntellectEU together with their customer Telindus (Proximus Group) on streamlined asset transactions, as well as Cloudsoft on deploying and managing global blockchain networks.
Our members reinforced that blockchain is not only impacting business on a global scale, but also across industries through blockchain talks from Huawei on telecom, Daimler on the industrial enterprise, Deloitte on regulation, Energy Blockchain Labs on reversing China carbon emissions, and a panel of speakers from Accenture, BanQu and Leading Directions on blockchain for good applications.
Hyperledger hosted three different panels on Tuesday moderated by Executive Director, Brian Behlendorf and Security Maven, Dave Huseby. Those panels were “The Role of Open Source in Blockchain,” “Blockchain in the Wild, PoCs, Pilots & Deployments” and “Security, Privacy and the Enterprise Blockchain.”
The panels were very well attended and there was great discussion on all three topics. It was most interesting that identity on the blockchain turned out to be the main topic of conversation during the security and privacy panel. And on that note, we’re excited with Hyperledger Indy just recently getting accepted into incubation under Hyperledger. Indy provides tools, libraries, and reusable components for providing digital identities rooted on blockchains.
We ended Consensus with a member party atop a NYC hotel rooftop. It was such a pleasure to see everyone and we are extremely grateful for all the support our community has provided around this event and overall. We’re looking forward to next year’s event – we hope that you can join us!
