Description

Operations Smart Contract (OpsSC) for Hyperledger Fabric v2.x - Tatsuya Sato, Hitachi, Ltd.

Operations Smart Contract (OpsSC) is a smart contract-based system operation tool for blockchain-based systems. This enables decentralized system operations over multiple organizations efficiently. OpsSC for Hyperledger Fabric v2.x was registered as a Hyperledger Labs project on Feb 2021 and is now available on https://github.com/hyperledger-labs/fabric-opssc. In OpsSC, a system operational flow is defined as a smart contract and each organization operates their own nodes according to the smart contract. The value of OpsSC is inter-organizational operations can be performed 1) without relying on decisions by a specific organization 2) with uniform procedure / parameters 3) efficiently. For applying this to Fabric, Tatsuya has developed OpsSC which is essential for managing Fabric network. It helps make end-to-end operational workflows for chaincode and channel operations more efficient.

A

Hello: everyone I'm tatia sato from hitachi.

A

In this session I introduce operations, smart contract ox sg, which is a smart contract-based system, operation tool for hybrid fabric-based systems, yes of sg get got registered as a hyperlink logos project in this february.

A

Okay, first I'd like to talk about what is ox sg as a background. A single blockchain vessel system is built across multiple organizations, and each organization has a separate administrators.

A

Our goal is establishing decentralized system operations across multiple organizations for blockchain vessel systems.

A

The primary idea is to define a system operational workflow as a smart contract like this, and each organization operates their own notes. According to the like this, as a result, j operations are unified over much organization.

A

We think that the value of our she is into organizational operations which can be performed without relying on decisions by a specific organization with unified, uniform procedure. Config parameters effect.

A

Let's move on to the hypogeal specific topics in the current fabric: individual operational tasks, like fear, commands, has been defined and single point of view to last is eliminated, for example, with the introduction of new chain good life cycle from version 2.0.

A

However, as a remaining issue, there is room for employment in end to end operational workflows, using the individual tasks to improve this issue. Grpsc for public version, 2.x aims to enhance negotiation and automation, capabilities, jobs, sg, negotiate, config parameters for relations and execute the operations to nodes and decentralized.

A

This scenario also, this right shows joba view of the current implementation.

A

The implementation consists of three components of sensitive code: api server and agent chaincode provides functions to manage operational workflows and issue change event, including the operational instructions.

A

Aka server provides rest api for each of the admin to interact with the occ change agent for each organization, execute operations based on the chemical event to all organized o to all nodes for the organization.

A

In a typical use case operator for an organization faster out of an operation.

A

And then administrators for other organizations vote for the proposal.

A

If a majority of board is collected by organizations, agents for each organization organization based on the chain called event, currently the implementation provider power, specific access g, which is essential for managing the public network for operating chain code and channels.

A

At the first phase.

A

This slide presents g of cssg for operating chango from version 2.0 new chain called lifecycle was introduced.

A

The new step for uploading chain, called definition from each organization, was added. It can eliminate centralized process in deploying changes.

A

However, as a remaining issue, it increases operations which are executed by each organization and must use the same permits.

A

Also, the admins will need and negotiate the source code and parameters with other organization in typical case, so sg streamlines end to end chain code deployment.

A

And organization create a proposal with chain called source code and application.

A

As a host, both folder proposal shared on gxsg when the majority of bots is collected and automatically deployed the chain code based on the proposal with downloading installing uploading and committing the change.

A

This right present gssg for operating channels.

A

The left part shows losses for general update across multiple organizations like adding an organization in the process. An organization must create a config tx to update the channel and then, as I will sign the config dx, so they need to share their complications so gxsgs rhyme rhymes such a generally across much organization.

A

The she counts is same as the round for operating chemicals.

A

Okay, now I give a demonstration using customized customer case network in public fiber examples.

A

This moment now, I'm during the demonstration, okay, the first scenario is adding a change.

A

This is the portal screen within the locking ops sg. In this scenario, three organization of one two three are ready.

A

Each organization argument uses a separated product for each organization. Now ob1 create and submit a new proposal to deploy a new chain code via the access sheet, and then the information is shared. Shadow of the obsession.

A

At the next step over to upload the proposal like this when the majority of our blue bar is collected, the agent for each organization will deploy the chain code to the nodes based on the obsession event.

A

Now the chain code is installed on the all keys.

A

And now the channel is deployed over nodes for all organizations.

A

In summary, gxsg enables decentralized coordination of operational information across magical organization.

A

It enables automated and unified chain code deployment.

A

The second scenario is adding a new organization of phone and, as an initial state, the three organization of one two three are ready: two out of four first.

A

Over 4 issue key and certificate for their nodes by using their shear outside of obsession.

A

Then false and msb information, including certificate to ob1.

A

That's all we want to create a proposal to add all 4 to system channel by using msp information for all4.

A

Now one is creating the proposal, and now we want submit it.

A

Next of two uploaded.

A

When, oh so now, agent uh agent update the channel state.

A

Now the organization are repeating for other application channels. Here, let me skip the steps.

A

After that overwhelm fetch the system complete row and send it to all form and all four launchers through their nodes, using the complete.

A

Block now, 4 is ready on the photo.

A

Also, you can see existing chain code are deployed on for the pier by grc sg. Let's go back to the.

A

A

Okay, here is the load map for office. She as a kind of time.

A

We have plans to improve the quality of existing features and also to develop new features for general purpose operations, which enables to execute arbitrary command via obsession.

A

Also, we aim to get the part of functionality of obsession measured in hybrid fabric in the future.

A

Now, obviously, she is available on this. uh This report.

A

And we welcome your feedback and contribution. Please feel free to contact us on the location, chat to channel or email and, as a related presentation, total from olaku will be giving a presentation with this title.

A

If you are interested, please check also his presentation.

A

And finally, let me check the question from audience.

A

Okay, there are no questions so far: okay, okay, that's all my presentation. Thank you for coming.
