The Azure Key Vault provides hardware security modules (HSM) that are maintained in the Azure Cloud. This allows client total control of their cryptographic materials in hardware and firmware without being exposed to any operators including Microsoft. Using an HSM based keys management provides the highest level of security.
Kaleido CloudHSM service supports using keys maintained by Azure Key Vault to sign transactions. The Kaleido service communicates with Azure Key Vault via HTTP over TLS to discover the list of signing accounts and sending it payload to sign. During the entire process the signing keys stay safe inside the customer's Azure Key Vault instance and are never shared with Kaleido.
Azure KeyVault Signer has the ability to interact with the Key Vault in Azure to sign and send transactions to an Ethereum node in the Kaleido environment.

Built for permissioned networks
Data isolation and strict governance enabled by Hyperledger Fabric certificate authority
Unique Execute-Order-Commit endorsement model where transactions are initially executed on a set of peers while ordering service handles packaging and delivery
Ordering can be switched based on the needs of the environment with pluggable consensus algorithms
Go, Java, Node.js
Since launching in 2015, Hyperledger Fabric has been a top choice for enterprises looking to build apps on permissioned blockchain networks. The modular architecture is capable of powering large-scale applications that require enterprise-grade data security.
The ability to protect certain details of peer transactions has made Hyperledger Fabric a go-to protocol for industries like financial services, supply chains, and the insurance industry. It works for complex use cases that involve personally identifiable information and proprietary business data.
Hyperledger Fabric is one of the many protocol choices available on Kaleido. With a full suite of plug and play services, flexible cloud deployment options, and powerful APIs, Kaleido is the easiest way to run a Fabric network anywhere.
Hyperledger Fabric is an open source project designed to handle enterprise-grade use cases. Key differentiators are its quick transaction throughput and its modularity, allowing for more innovation and optimization regardless of industry use cases. Other benefits include scalability and security, key pillars of any enterprise application.
Hyperledger Fabric is a modular blockchain framework that allows you to plug in different components, such as consensus algorithms and membership services, and tailor networks to your needs
Part of the Hyperledger project of the Linux Foundation, Hyperledger Fabric is an open source protocol that allows the enterprise to build custom applications and limit vendor risks
With a high level of security for enterprise users, Fabric uses a permissioned network to prevent unauthorized access
Kaleido is a Hyperledger Certified Service Provider (HCSP) with a deep expertise in helping enterprises successfully adopt Hyperledger tools. Our founding partners are also active with the Hyperledger Foundation. Sophia Lopez is a General Member representative on the Hyperledger Foundation Governing Board and Jim Zhang is a member of the Hyperledger Foundation Technical Oversight Committee.
Talk to an ExpertQuorum is a blockchain protocol specially designed for use in a private blockchain network, where there is only a single member owning all the nodes or a consortium blockchain network where multiple members each own a portion of the network.
Quorum is designed to be highly scalable, with low transaction latencies and the ability to support a higher number of transactions per second than other blockchain protocols. This makes it well-suited for use in high-volume applications.
Quorum includes a number of security features that are designed to protect sensitive or proprietary data, like private transactions that allow network participants to transact without revealing the details of their transactions to the rest of the network.
Quorum is based on the Ethereum protocol and can support a wide range of decentralized applications and smart contracts. It is also highly modular and customizable so that it can be tailored to the needs of specific use cases.
There is no cost required to submit transactions to a Quorum network, unlike Ethereum, which requires the payment of high and unpredictable gas fees to submit transactions.

Talk to an ExpertCreation of Kaleido CloudHSM service in Kaleido is a two step process. First, you specify the type and access details to Azure Key Vault as a configuration under the environment. This can be referenced by one or more cloud HSM service instances created in the same membership. Next you create the CloudHSM service using the configuration created belo.
The configuration for Azure Key Vault has the following mandatory parameters:
The following is a sample POST request to create an Azure key vault cloudhsm configuration:
Using the configuration created above, cloud HSM service can be created using the request fields:
FieldUsagenameUser-defined name for the servicemembership_idID of membership under which this service is availableserviceType of service. Must be cloudhsmdetails-- cloudhsm_idID of the configuration created in the previous step
The following is a sample POST request to create a Cloud HSM service that uses an Azure Key Vault backend provider:
Transactions can be sent to the Kaleido CloudHSM service by specifying a from address that corresponds to a SECP256K1 type key that is present in the Azure Key Vault. Any of RPC, WSS or the API Gateway interfaces can be used to send transactions. The URLs for the interfaces can be obtained by querying the service's /status route
A sample GET request to obtain the service status is as below:
When a eth_sendTransaction request is received by the Kaleido CloudHSM service, it uses the from address to determine whether the configured backend cloud HSM contains the keys for the address. The Kaleido CloudHSM service sends a /sign request with the KEY ID of the from address and the transaction payload to Azure Key Vault to sign. If the request succeeds, Key Vault returns the signature, from which the Ethereum signature parameters - R, S and V are extracted, as well as making sure the S value is compatible with Ethereum's malleability protection rule, and included in the transaction before sending it to the Ethereum blockchain node in the Kaleido environment that the service is bound to.
Hyperledger Fabric is a private blockchain that allows developers to create subnets, or channels, meaning that certain proprietary or personal information can remain confidential. This makes Fabric a protocol of choice for industries like financial services, insurance, and supply chain management.
Businesses reach production faster when they combine Avalanche Subnets with the full suite of web3 development tools offered on the Kaleido platform.
When you launch Polygon Supernets on Kaleido, you access the unique scaling solutions Polygon has to offer and an array of pluggable tools to mint tokens, create assets, and monitor activity—making it easier than ever to stand up ambitious web3 apps.
Quorum is a protocol of choice for industries like financial services, insurance, and supply chain management where enterprise-grade.
