REST API Gateway

Simplify Blockchain Development With Powerful APIs

Enterprise-grade blockchain APIs to deploy and manage Smart Contracts, send Ethereum transactions, query blockchain data, and more.

What it is

A Full Suite of APIs to Make Blockchain Development Easy for Any Developer

The REST API Gateway gives application developers everything they need to focus on their app's business logic and user experience, without getting stuck in the complexities of Ethereum transaction submission, thick Web3 client libraries, nonce management, RLP encoding, transaction signing, and smart contract management.

Just use the intuitive REST APIs generated for you, along with industry standard OpenAPI (Swagger) definitions and management APIs.

Let the REST API Gateway take care of the rest, backed by a fully-managed high throughput Apache Kafka infrastructure.  Keep track of your deployed smart contracts, with descriptive names and API documentation, rather than strings of Hex addresses.

Deploy Your First Smart Contract in Seconds

All of the complexities of submitting transactions to Ethereum are handled for you. With one click in the UI you can deploy your first smart contract, then explore that API to send transactions, and read data in a convenient web experience. No special blockchain coding expertise required.

REST APIs for Your On-Chain Logic & Data

OpenAPI (Swagger) definitions are generated for the Solidity Smart Contracts you enable on the REST API Gateway. The Blockchain becomes as simple to code against as any modern web based system. No thick client libraries needed in your app, no complex type mapping. Connect directly from your core applications, or use your existing Integration tier / Enterprise Service Bus (ESB).

Reliable Transaction Streaming, over Apache Kafka

The REST API Gateway handles smart contract compilation, nonce management, RLP encoding and more. It's all backed by the industry standard for reliable ordered streaming of transactions - Apache Kafka. So the same convenient APIs take you from first use, through to enterprise grade production use cases at scale.

Hyperledger Fabric at a glance

Permissions

Built for permissioned networks

Governance

Data isolation and strict governance enabled by Hyperledger Fabric certificate authority

Transaction Flow

Unique Execute-Order-Commit endorsement model where transactions are initially executed on a set of peers while ordering service handles packaging and delivery.

Consensus Algorithms

Consensus protocols such as Solo, Practical Byzantine Fault Tolerance (PBFT), Raft or Kafka (to be able to use several ordering nodes) can be plugged in.

Smart Contract Language

Go, Java, Node.js

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. A key differentiator is its quick transaction throughput. Developers choose to build applications with Hyperledger Fabric because of its modularity. It’s flexible, allowing for more innovation and optimization regardless of industry. Other benefits include scalability and security, key pillars of any enterprise application.

Better performance

One click is all it takes to deploy Ethereum nodes in the Unlike other private networks that require every peer to execute transactions and maintain a full ledger, Hyperledger Fabric allows for more delineation of roles among members

Open source

Part of the Hyperledger project of the Linux Foundation, the architecture of Hyperledger Fabric allows for scale and performance

Permissioned network

Developers can build subnets or channels to keep certain transactions and data private while maintaining a shared ledger

How it works

How it Works

Blockchain Development, Simplified

Kaleido provides the enterprise grade connectivity your applications and back-office systems need for high throughput reliable connectivity to your on-chain smart contracts. You can submit transactions to your nodes with ease, query the data on your chain, and listen to events. We generate modern REST APIs with full OpenAPI (Swagger) documentation from your Solidity source code, with all of the methods, events and types processed – even the developer docs loaded into the definition. 

For simple first use you can then perform transactions synchronously against the chain, waiting for them to complete. Then as you move towards production, use our throttling and nonce management over our Kafka backbone to stream transactions into the chain. Of course all of this is in addition to having direct JSON/RPC access to your nodes, for development of smart contract logic using Truffle, or DevOps activities with a Geth console.

Deploy and manage your Smart Contracts via our blockchain API and user interface. You upload your .sol or .zip file containing your Solidity package, and we generate you a REST API that can interact with any on-chain contract with the same Application Binary Interface (ABI). 

For example, if you upload an ERC20 contract you get an interface that can query common data and submit transactions to any ERC20 based contract. You can use this generated gateway REST API to deploy new contract instances, which you know are using the same Solidity package and compiler version. e.g. each contract instance is identical. The UI and REST API of the gateway lets you manage these instances.

Web3 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.
