WARNING: the libraries are still undergoing breaking changes as we get better ideas and start building out the Apps.
**Note: Requires Go 1.9+**
The Cosmos SDK is a platform for building multi-asset Proof-of-Stake
cryptocurrencies, like the [Cosmos Hub](https://cosmos.network). It is both a
library for building applications and a set of tools for securely interacting
with them.
The goals of the SDK are to abstract away the complexities of building a
Tendermint ABCI application in Golang and to provide a framework for building
interoperable blockchain applications in the Cosmos Network.
It is inspired by capabilities-based security, and informed by years of
wrestling with blockchain state machines.
The SDK is fast, safe, and easy-to-use. It is generic enough to be used to
implement the state machines of other existing blockchains, like Bitcoin and
Ethereum, allowing seamless integration with them and their data structures.
It comes with batteries included, is easily extensible, and does not require
developers to fork it to access any of its current or extended functionality.
It provides both REST and command line interfaces for secure user interactions.
Applications in the Cosmos-SDK are defined in terms of handlers that process
messages and read and write to a store. Handlers are given restricted
capabilities that determine which parts of the store they can access. The SDK
provides common data structures for Accounts, multi-asset Coins, checking
signatures, preventing replay, and so on.
For more details on the design goals, see the [SDK Guide](docs/guide.md)
## Prerequisites

**WARNING**: the libraries are still undergoing breaking changes as we get better ideas and start building out the Apps.
**Note**: Requires [Go 1.9+](https://golang.org/dl/)
## Overview
The Cosmos-SDK is a platform for building multi-asset Proof-of-Stake (PoS) blockchains, like the [Cosmos Hub](https://cosmos.network). It is both a library for building and securely interacting with blockchain applications.
The goal of the Cosmos-SDK is to allow developers to easily create custom interoperable blockchain applications within the Cosmos Network without having to recreate common blockchain functionality, thus abstracting away the complexities of building a Tendermint ABCI application. We envision the SDK as the `npm`-like framework to build secure blockchain applications on top of Tendermint.
In terms of its design, the SDK optimizes flexibility and security. The framework is designed around a modular execution stack which allows applications to mix and match elements as desired. In addition, all modules are sandboxed for greater application security.
It is based on two major principles:
- **Composability**: Anyone can create a module for the Cosmos-SDK and integrating the already-built modules is as simple as importing them into your blockchain application.
- **Capabilities**: The SDK is inspired by capabilities-based security, and informed by years of wrestling with blockchain state machines. Most developers will need to access other 3rd party modules when building their own modules. Given that the Cosmos-SDK is an open framework and that we assume that some those modules may be malicious, we designed the SDK using object-capabilities (_ocaps_) based principles. In practice, this means that instead of having each module keep an access control list for other modules, each module implements `keepers` that can be passed to other modules to grant a pre-defined set of capabilities. For example, if an instance of module A's `keepers` is passed to module B, the latter will be able to call a restricted set of module A's functions.
The capabilities of each `keeper` are defined by the module's developer, and it's their job to understand and audit the safety of foreign code from 3rd party modules based on the capabilities they are passing into each 3rd party module. For a deeper look at capabilities, you can read this [article](http://habitatchronicles.com/2017/05/what-are-capabilities/).
_Note: For now the Cosmos-SDK only exists in [Golang](https://golang.org/), which means that developers can only develop SDK modules in Golang. In the future, we expect that the SDK will be implemented in other programming languages. Funding opportunities supported by the Tendermint team may be available eventually._
## Application architecture
#### Modules
The Cosmos-SDK has all the necessary pre-built modules to add functionality on top of a `BaseApp`, which is the template to build a blockchain dApp in Cosmos. In this context, a `module` is a fundamental unit in the Cosmos-SDK. Each module is an extension of the `BaseApp` functionalities that defines transactions, handles application state and the state transition logic. Each module also contains handlers for messages and transactions, as well as REST and CLI for secure user interactions.
Some of the most important modules already integrated in the SDK are:
- `Auth`: Defines a standard account structure (`BaseAccount`) and how transaction signers are authenticated.
- `Bank`: Defines how coins (i.e cryptocurrencies) are transferred.
- `Governance`: Governance related implementation including proposals and voting.
- `Staking`: Proof of Stake related implementation including bonding and delegation transactions, inflation, fees, unbonding, etc.
- `IBC`: Defines the intereoperability of blockchain zones according to the specifications of the [IBC Protocol](https://cosmos.network/whitepaper#inter-blockchain-communication-ibc).
#### Directories
The key directories of the SDK are:
- `baseapp`: Defines the template for a basic [ABCI ](https://cosmos.network/whitepaper#abci) application so that your Cosmos-SDK application can communicate with the underlying Tendermint node.
- `client`: CLI and REST server tooling.
- `server`: RPC server to communicate with the node.
- `examples`: Contains examples on how to build working standalone applications.
- `store`: Contains code for the multistore (_i.e._ state). Each module can create any number of `KVStores` (key-value stores) from the multistore.
- `types`: Common types required in any SDK-based application.
- `x`(for e**X**tensions): Folder for storing the `BaseApp` module and all the already-built modules described in the previous section.
