Hello World, Meet Seth (Sawtooth Ethereum)

By Hyperledger Blog, Hyperledger Burrow, Hyperledger Sawtooth

Guest post: Adam Ludvik, Bitwise IO, Casey Kuhlman, Monax

One of the dreams of bringing multiple distributed ledger projects together under a single roof at Hyperledger is that we would find ways to collaborate, learn, and grow to the benefit of all projects involved. To this end, an initial proof-of-concept integration between the Hyperledger Sawtooth and Hyperledger Burrow projects was recently completed. As a result of this integration, “simple” EVM smart contracts can now be deployed to Hyperledger Sawtooth using the “Seth” (Sawtooth Ethereum) Transaction Family.

The Seth family consists of a new client, `seth`, that is used to construct and submit transactions to the network and a new transaction processor, `seth-tp`, that runs the Burrow Ethereum Virtual machine. Thanks to the modular design of Hyperledger Sawtooth, getting the Hyperledger Burrow EVM running under Hyperledger Sawtooth was relatively easy. Transaction processors run in a separate process and communicate with the validation process over a network interface. The Hyperledger Burrow EVM code was wrapped in an adapter but was otherwise left unmodified.

While working together on common ground, a cross-pollination of ideas took place to the benefit of both projects. Hyperledger Sawtooth gained an EVM implementation and added plans for the following new core features:

Core and family-defined Events
Transaction execution receipts
Batch injection
On-chain block validation rules

These core features will enrich the toolset available to application developers and enable Hyperledger Sawtooth to move the Hyperledger Burrow EVM integration past the initial proof-of-concept phase. The next step in this integration is enabling developers with existing web applications and smart contracts to seamlessly transition their work to the Hyperledger Sawtooth platform. A major part of making this transition possible will be the creation of a `seth-rpc` server that supports the Public Ethereum and Burrow JSON-RPC interfaces. The architecture of the integration after this step is shown below.

Hyperledger Burrow benefited from the integration in two major areas. First by working with the Sawtooth team and leveraging its capacity to offer parallel processing of transactions the effort represents the very first iteration towards non-serialized processing of EVM based transactions. Within the EVM community it has long been understood that one of the most important aspects of scaling is the need to move beyond strictly serial processing of transactions. The Hyperledger Sawtooth-Burrow integration is the first tangible code which addresses this giant need within the community of EVM users.

Secondly, Hyperledger Burrow has long been positioned to provide a core EVM that would then be utilized by other Hyperledger projects. This integration validates that positioning and establishes a strong upstream-downstream relationship between the Sawtooth and Burrow projects. Successful open source endeavours are community driven, collaborative efforts and this linkage between the Hyperledger Sawtooth and Hyperledger Burrow teams reinforces that ethos.

Hyperledger’s Monthly Technical Update

By Hyperledger Blog, Hyperledger Burrow, Hyperledger Composer, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth

As our incubated projects continue to mature, we’d like to update the community monthly on the progress we make. Below are June updates on Hyperledger projects.

Hyperledger Burrow

Implementation of dynamic memory on the Ethereum Virtual Machine
New type-safe Application Binary Interface package for translating data to Ethereum contracts into packed Ethereum bytes for transaction formulation (logical requirement for Ethereum chain; but all package implementations thus far have been GPLv3 licensed, as such in tooling code not included in Burrow; this new package will be able to go into Hyperledger Burrow under Apache license)
Alpha of batching client for new API with high transaction throughput (> 400 tx/s)
Various bug fixes
First prototype of Burrow EVM to run as transaction processor on Hyperledger Sawtooth Ledger

Hyperledger Cello

A user dashboard was added to support seeing blockchain status and chaincodes.
The k8s support features was started with intern students; Upgrade swarm support to latest version (17.04).
Refine the installation scripts to support multi-os-distributions.
Fabric 1.0-* supported scripts was added.

Hyperledger Composer

We completed all rebranding activities as part of the move to Hyperledger – we moved to the Hyperledger Docker Hub organization, and renamed the Yeoman generator module.
We added support for modelling and publishing events from a transaction processor function, allowing client applications and existing systems to respond to events from a deployed business network.
We made extensive changes to our new user and getting started documentation, including reworked installation guides and tutorials which are available in the docs: https://hyperledger.github.io/composer/introduction/introduction.html
We delivered a set of nodes for Node-RED which allow developers to easily build outbound and inbound integration between a deployed business network and external system using IoT/MQTT, WebSockets, TCP, etc.
We added experimental support for invoking external HTTP APIs from within a transaction processor function, allowing external data such as share prices to be used within business logic.
We are currently focusing on delivering Hyperledger Fabric v1.0 beta support, complex query support (by exploiting CouchDB), and a new vehicle lifecycle demo that shows off the power of Composer.

Hyperledger Explorer

No major updates to report this month.

Hyperledger Fabric

Hyperledger Fabric v1.0.0-beta was released, and the maintainers plan on weekly releases until we have a demonstrably stable release candidate. We hope to be able to release in late July if all goes well.
The project’s engineers have significantly increased test coverage (+82%) and reduced its open defect count (~130 -> 22) since the 1.0.0-alpha2 release. It has been encouraging to see the diversity of contributions. It the past month alone, we have had contributions from 73 individuals representing 12 companies (including IBM) and 12 unaffiliated individuals.
The project is seeing a steadily increasing stream of downloads of the milestone releases with global coverage (US, Brazil, China, India, UK, Germany, France, Croatia, Russia, Japan, Indonesia, Australia and even Pakistan). There is an abundance of interest in China, India and Japan, nearly rivaling the US.
The remaining focus is on improving the documentation, continuing to test and fix bugs, and complete the various license, crypto-export and security scans.

Hyperledger Indy

No major updates to report this month.

Hyperledger Iroha

No major updates to report this month.

Hyperledger Sawtooth

Consensus 2017 is a Wrap!

By Hyperledger Events, Finance, Healthcare, Hyperledger Burrow, Hyperledger Cello, Hyperledger Composer, Hyperledger Explorer, Hyperledger Fabric, Hyperledger Indy, Hyperledger Iroha, Hyperledger Sawtooth

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.

Hyperledger was a sponsor of the event. The Hashed Health development team ended up winning the Hyperledger challenge, which was to create a game using any of the Hyperledger frameworks.

(Winning team of the Hyperledger hackathon challenge and Hyperledger Executive Director, Brian Behlendorf)

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.

Dutchess incorporated:

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.

(Hyperledger roundtable participants: Makoto Takemiya, Soichiro Takagi, Kelly Olsen & Ted Tanner)

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 Role of Open Source in Blockchain panelists: Dan Middleton, Intel, Casey Kuhlman, Monax, Makoto Takemiya, Soramitsu & Amber Baldet, J.P. Morgan)

(Blockchain in the Wild, PoCs, Pilots & Deployments panelists: Jesse Chenard, MonetaGo, Ashwin Kumar, Deutsche Boerse, Ram Komarraju, CLS Group, Corey Todaro, Hashed Health & David Treat, Accenture)

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.

(Security, Privacy and the Enterprise Blockchain panelists: Justin Newton, Netki, Drummond Reed, Sovrin Foundation, Jeff Garzik, Bloq & Astyanax Kanakakis, Norbloc)

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!

Hyperledger Fabric

We agreed to a feature/code freeze at the Hackfest in DC, and selected co-release managers for the v1.0 release: Chris Ferris (IBM) and Jonathan Levi (Hacera).
At the hackfest, we also discussed and agreed on some changes to the development process proposed by Dave Huseby, which we will implement as a function of creating the release branch for v1.0.0-alpha2.
The TL;DR: of the proposal is that we will manage change through feature branches that will be merged into a development branch to undergo the full gauntlet of testing, and reverted if they still need work. Once the development branch has merged the set of features agreed for a release, the develop branch will be fast forward merged into the release branch (also the master branch), tested once more, and then published. The release/master branch which will always have the most recent stable release as the default on GitHub (as opposed to the head of development as is the case today).
Hyperledger Fabric added three new maintainers to help keep reviews up with the pace of change requests.
The rate of bug fixing has consistently outpaced reporting for the past 3 weeks, with in excess of 50 defects resolved per week.
The unit test coverage has seen steady improvement, now more than 70% (it had been 61%) with many key areas of the code at 100%. The integration test framework is taking shape and we expect to have regular testing (daily, performance/scale and long running) operational shortly.
Maintainers cut a v1.0.0-alpha2 release the week of May 8

Hey – You got your Ethereum in my Hyperledger!

By Brian Behlendorf Blog, Hyperledger Burrow

Last Thursday marks another important milestone in the Hyperledger books: the Hyperledger Technical Steering Committee (TSC) approved a proposal submitted by engineers at Monax and Intel, to incubate the community’s first Ethereum derived project – Burrow, a permissionable smart contract machine.

The Burrow project originated with Monax as eris-db, and has been open source since December 2014. The project has been relicensed to Apache Software License 2.0, in accordance with the Hyperledger governance requirements.

Burrow, becoming a project under Hyperledger, is important for a variety of reasons:

First, and foremost, having an Ethereum derived project under the Hyperledger umbrella should send a strong message that any positioning of the Hyperledger and Ethereum communities as competitive is incorrect.

The blockchain technology community still has many technical challenges to solve, and many different possible approaches to solving them. “Permissioned” and “unpermissioned” represent two ends of a range of options for configuring a distributed ledger, not a binary choice. Choices we can make at the smart contract layer are even more complex. Being able to collaborate on various approaches to these problems is fundamentally important to getting really innovative ideas into production-quality code as quickly as possible.

Secondly, with an Apache licensed Ethereum Virtual Machine (EVM), other distributed ledger projects in Hyperledger (e.g. Fabric, Sawtooth Lake and Iroha), can now experiment with integrating the EVM into their respective platforms. There is still much work to do to make this happen, of course, but the prospect of this is now much more tangible. This also marks the start of a productive relationship with the broader Ethereum community, including the Enterprise Ethereum Alliance as we monitor the specifications developed there for their application towards Burrow.

“We’re extremely excited that Burrow has been accepted into Hyperledger. This is a huge step in creating a forum in which the larger enterprise community can contribute towards building production-grade applications with the EVM smart contact interpreter. Inclusion of the code base in Hyperledger will ensure the longevity of the open source project under the mature devops and governance of The Linux Foundation and will be a primary driver toward the realization of enterprise grade ecosystem applications.” – Casey Kuhlman, Monax

I know that many in the community have been looking forward to (and working towards!) this day. I think it will mark an important point in Hyperledger’s (and blockchain) history. Stay tuned, as we’ll be moving the Burrow project to Hyperledger infrastructure over the next few weeks.
