# Platform & Toolchain

## Local development environment

* [Getting Started](/infrablockchain-antelope/for-developers/developer-guides-infrablockchain-antelope-native/development-environment-infrablockchain-antelope-native/prerequisites.md): Install the InfraBlockchain-Antelope platform in your local development environment.

## Toolchain

The InfraBlockchain-Antelope platform is made up of the following components and toolchain:

1. `infra-node`:  the core InfraBlockchain-Antelope node daemon that can be configured with plugins to run a node. Example uses are block production, dedicated API endpoints, and local development.
2. `infra-cli`: the command line interface to interact with the blockchain and to manage wallets.
3. `infra-keychain`: the component that securely stores InfraBlockchain-Antelope keys in wallets.
4. `infrablockchain.cdt`: toolchain for WebAssembly (Wasm) and a set of tools to facilitate smart contract writing for the InfraBlockchain-Antelope platform.

The basic relationship between these components is illustrated in the following diagram:

InfraBlockchain-Antelope also provides a frontend library for javascript development called Infrablockchain-js.

## Infra-node

Infra-node is the core InfraBlockchain-Antelope node daemon. Infra-node handles the blockchain data persistence layer, peer-to-peer networking, and contract code scheduling. For development environments, Infra-node enables you to set up a single node blockchain network. Infra-node offers a wide range of features through plugins which can be enabled or disabled at start time via the command line parameters or configuration files.

## Infra-cli

`infra-cli` is a command line tool that interfaces with the REST APIs exposed by `infra-node`. You can also use `infra-cli` to deploy and test InfraBlockchain-Antelope smart contracts.

## Infra-keychain

`infra-keychain` is a key manager daemon for storing private keys and signing digital messages. `infra-keychain` provides a secure key storage medium for keys to be encrypted in the associated wallet file. The `infra-keychain` daemon also defines a secure enclave for signing transaction created by `infra-cli` or a third party library.

`infra-keychain` can be accessed using the wallet API, but it is important to note that the intended usage is for local light client applications. `infra-keychain` is not for cross network access by web applications trying to access users' wallets.

## Infrablockchain.cdt

Infrablockchain.cdt is a toolchain for WebAssembly (Wasm) and a set of tools to facilitate contract writing for the InfraBlockchain-Antelope platform. In addition to being a general-purpose WebAssembly toolchain, Antelope-specific optimizations are available to support building InfraBlockchain-Antelope smart contracts. This new toolchain is built around Clang 7, which means that InfraBlockchain.cdt has most of the current optimizations and analyses from LLVM.

## Infrablockchain-js

A Javascript API SDK for integration with InfraBlockchain-Antelope-based blockchains using the InfraBlockchain-Antelope RPC API.
