What it is

Secure Off-Chain Messaging for Blockchain Networks

Kaleido’s platform is fully equipped with the communication functionality modern business networks need to streamline their operations, including our secure, built-in off-chain communication for high throughputs that are not suitable for on-chain messaging. Our App2App messaging uses Kafka, the industry standard, and is encrypted for the utmost protection. No extra middleware is needed.

Furthermore, it’s easy to develop your Dapp in the language of your choice using modern APIs for data transfer on top of the core Kafka protocol using the industry standard Socket.IO.

Your Choice of Key Management

Kaleido uses PKCS #7 (Public Key Cryptography) standards with strong encryption keys, which you can manage yourself or have Kaleido manage on your behalf. We pin the identity associated with the keys to both your organization ID (pinned by public key infrastructure - PKI) and your on-chain identity.

Remain Confident in Your Confidentiality

The end-to-end encryption ensures that only your recipient receives your intended message and your data remains secure.

Using the Service

Senders and recipients are addressed through customizable names called destinations. To create a destination, open the App2app service dashboard, click on "Add Destination" and follow the on-screen instructions. Once the destination has been created, the API endpoint will be shown. Connect your application to this endpoint using Socket IO.

What Is Hyperledger Fabric?

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.

Benefits of Hyperledger Fabric

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.

Modular & Pluggable

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

Open source

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

Security

With a high level of security for enterprise users, Fabric uses a permissioned network to prevent unauthorized access

Benefits of Quorum

Quorum 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.

Scalability

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.

Security

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.

Flexibility

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.

Gas-free transactions

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.

How it works

How it Works

The Kaleido messaging service offers a Kafka-backed bilateral app-to-app pipeline for the encryption, submission and decryption of messages between members of an environment. Apps can securely subscribe to pertinent topics for consumption and delivery of data, without reliance on ancillary messaging constructs and subsequent integration of offline data. 

The service leverages the On-Chain Registry to establish and verify membership identities. Messages are automatically encrypted and signed, thereby ensuring that only the intended recipient can access the content while also providing proof of the sender’s identity.

Deploying an App to App Messaging Service Instance

You can elect for one of two approaches to provision App to App Messaging Service Instances: Kaleido Console UI or Admin API. For users unfamiliar with the Kaleido REST API, the console interface is the recommended happy path. Both approaches will ultimately result in a new instance of the App to App Messaging Service instance running within the specified environment.

Enterprise Use Cases
Run Better on Kaleido

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.

Supply Chains

Hyperledger Fabric networks can increase transparency and traceability of transactions within the network. This transparency can be used to monitor real-time location data, limit fraud and counterfeit goods, and track ESG efforts.

Digital Assets

Complex multi-party business networks built on Fabric can easily tokenize assets, transact instantly, share data, and eliminate cumbersome paperwork as financial business flows are automated.

Insurance

Moving insurance transactions to blockchain can eliminate fraud, automate claim processing, and digitize legacy systems. Hyperledger Fabric also allows stakeholders to automate Know Your Customer (KYC) processes via smart contracts.
