So customers need to go thru an awareness journey to understand what like smart contracts can do for their business, and how can they improve the operations in their network using blockchain.
IBM is a premier member of the Linux Foundation Hyperledger Project, which is an open source, collaborative effort that seeks to advance blockchain technologies. The Platform also provides tools to help you align the needs of developers and business leaders in your organization.
Transferring assets is the heart of blockchain. How can people buy and sell or transfer goods in a business network without any central governing body or policy? Look at web demo Hyperledger Composer.
When a transaction is submitted, the blockchain run time is going to find the script functions that are interested in that transaction and then run them. And those script functions can have side effects on assets that are being managed in asset registries. Smart Contract: Software running on a ledger, to encode assets and the transactions instructions for modifying the assets. Peer network: A broader term overarching the entire transactional flow, which serves to generate an agreement on the order and to confirm the correctness of the set of transactions constituting a block.
Membership: membership services authenticates, authorizes and manages identities on a permissioned blockchain network. Events: creates notifications of significant operations on the blockchain e.
Systems Integration: Responsible for integrating blockchain bi-directionally with external systems. Not part of the blockchain. Developers care about application and smart contracts. Skip to content.

IBM Blockchain Platform Extension for VS Code
By leveraging Kubernetes secrets, you developer sensitive data outside your Kubernetes pods and containers, which frees up for from having to bundle the for code with restricted information. One of the main goals of using developer technology essentials to blockchain irrefutable proof that a set of transactions have occurred between members of a essentials network. It could even enable someone to issue transactions on the network. Hyperledger Composer is like the API. Blockchain extension uses telemetry reporting to track usage data and help improve future extension versions. Thank you so much DataTrained.

About the Program
In such cases, it might be good to have a PKCS 11 proxy, which can serve as the bridge between the client application and the library provided by the HSM manufacturer. The proxy is used as a bridge between Fabric nodes and the library provided by the HSM manufacturer. We like to refer to this software component as the HSM proxy. To reiterate, the HSM proxy component 1 uses dynamic linking for loading at runtime the library provided by the HSM manufacturer and 2 provides a TCP endpoint for communication, which allows decoupling from the Hyperledger Fabric nodes in other words, the HSM proxy component does not need to be part of the container image that hosts the Hyperledger Fabric node.
For example, if you only have an HSM proxy pod and the zone where that pod is running has an outage, then even with an HA HSM group in place, you will have downtime. For the SafeNet Luna devices, creating a replica of an HSM proxy pod requires performing the following two tasks upfront:. Completing these two tasks upfront means executing them prior to the deployment of the HSM proxy pods. Once these tasks are completed, you will have:.
The IBM Blockchain Platform stores, by default, the private keys associated with the identities of your Hyperledger Fabric nodes certificate authorities, peers, and orderers in Kubernetes secrets.
A Kubernetes secret is an object meant to store sensitive data. Storing sensitive data in secrets gives you control over access and usage of such data. By leveraging Kubernetes secrets, you keep sensitive data outside your Kubernetes pods and containers, which frees up developers from having to bundle the application code with restricted information. Because the data in Kubernetes secrets is stored in base64 encoding, you might need additional security measures for your Kubernetes secrets data.
For instance, you can add another layer of security by encrypting your Kubernetes secrets data at rest.
On the IBM Cloud, you can do so by:. When you take these steps, your Kubernetes secrets are encrypted with a symmetric key stored in Key Protect. However, note that this approach is by no means equivalent to using your own HSM device for storing the keys associated with your Hyperledger Fabric nodes. Instead, Key Protect uses shared HSM devices which they solely administer to store the symmetric key for encrypting your Kubernetes secrets data at rest. It is a subtle and relevant difference to keep in mind.
As described previously, HMS appliances provide higher security for safeguarding private keys. For instance, an HSM appliance might go out of service the moment tampering is detected. Also, cryptographic material generated in an HSM appliance does not leave the device, and, as a result, cryptographic operations occur within the device itself.
To sum up, you can leverage Key Protect to encrypt the sensitive data stored in your Kubernetes secrets as opposed to just simply encoding that data in base64 format.
Having a sound HA architecture helps mitigate the possibility of outages and downtime in your blockchain network and helps your organization meet non-functional requirements around reliability and redundancy. Ensuring the deployment of your HSM components like the HSM appliances and HSM proxy pods follows best practices for high availability and recovery from data loss should be part of your overall architecture and design efforts for your IBM Blockchain Platform network. It is worth mentioning that in addition to storing the keys for the Fabric nodes in other words, peers, orderers, and certificate authorities in an HSM appliance, you should also consider storing the keys for the following in the HSM:.
Taking these measures for safeguarding these peripheral keys should provide further security. Doing so significantly reduces the possibility of compromising those adjacent software components that have access to the blockchain network. Of course, for this to be effective, you should ensure the maximum enrollments property of the identity is set appropriately at registration time the maximum enrollments value limits the number of times that the same password can be used for generating a private key and corresponding certificate.
For further details on the maximum enrollments property, see the Fabric CA documentation. If leveraging HSM appliances is not a feasible option for your organization but you would still like to provide an additional layer of security for your keys, you can instead configure your IBM Kubernetes Service cluster instance to use Key Protect as the KMS.
This action ensures that your digital keys for the Fabric nodes are encrypted at rest. Get involved Close outline. Close Close. Hyperledger Fabric Hyperledger. Related Article Secure your blockchain solutions.
