Cosmos SDK is a toolkit for developing blockchain-based applications. This framework, developed by the Tendermint team, offers developers a variety of tools and components for creating unique distributed applications.
Description of Cosmos SDK
Cosmos SDK is a platform that simplifies the task of building custom blockchains for developers.
Previously, developers faced a choice: develop a blockchain from scratch or use Ethereum and its variants. Creating a blockchain based on Ethereum is relatively simple, as developers can connect to existing Ethereum network layers and consensus, developing applications on EVM (Ethereum Virtual Machine). However, this limits customization capabilities.
To build your own blockchain, you need a group of validators, which may not be available to hobbyist developers of decentralized applications. In these circumstances, deploying a contract on Ethereum is a simpler and faster solution. Understanding this, the Cosmos team created Ethermint, an Ethereum analogue within the Cosmos SDK, where developers can use their Ethereum code without worrying about customization, as the set of validators is already provided.
Key Features of Cosmos SDK
Cosmos SDK is suitable for creating both private and public blockchains. It is ideal for developing decentralized financial applications, decentralized exchanges, blockchain games and other high-performance applications that require scalability. This tool significantly simplifies, accelerates, and makes the process of creating high-quality third-generation blockchains more accessible. Its main features include:
| Feature | Description |
|---|---|
| Modular Structure | Cosmos SDK offers a modular approach, allowing developers to combine different components, like Lego, to create specialized blockchain networks. These components include account management, token functions, and support for inter-blockchain connections. |
| High Performance | Using Tendermint Core to achieve consensus, blockchains built on Cosmos SDK are capable of processing thousands of transactions per second, which is significantly higher than most traditional blockchains. |
| Inter-blockchain Compatibility | Cosmos SDK simplifies inter-blockchain communications with the IBC (Inter-Blockchain Communication) protocol, allowing different blockchains developed on various platforms to interact securely with each other. |
| Flexibility in Development | The platform supports the creation of applications in various programming languages thanks to gRPC, ensuring flexible interaction between modules. |
| High Level of Security | Cosmos SDK provides an advanced system of rights and access management, ensuring a high level of security. In addition, the Tendermint Core consensus mechanism provides reliable system-level protection. |
Cosmos SDK includes all necessary components "out of the box": staking mechanisms, voting and governance systems, and the ability to issue your own cryptocurrency. Cosmos SDK is an effective solution for developing blockchain applications, providing:
- flexibility;
- scalability;
- security.
As the application does not compete with others for block space or is not limited by the computational capabilities of the virtual machine, performance is improved and is only limited by the state machine itself. It opens new horizons for innovation in the field of distributed technologies, allowing the creation of complex and interconnected blockchain ecosystems.
Limitations of Blockchain Technology
The virtual machine interprets smart contracts to change the state of the blockchain machine. This is convenient for developers and easy to use for deploying applications, but has certain limitations:
- Use of a specific programming language accepted by the virtual machine;
- Limited set of virtual machine functions and lack of flexibility;
- All smart contracts are executed by the same virtual machine, limiting performance as all applications compete for block resources;
- Limited sovereignty, meaning the application depends on the governance decisions of the underlying blockchain.
From a security standpoint, developers are not limited to the cryptographic functions of the virtual machine or any other mechanisms that may be used, and can rely on their own cryptography or proven libraries.
In conclusion, Cosmos SDK offers a simple and fast way to create a specialized blockchain for applications, relying on efficient and proven technologies without compromises in the areas of security and sovereignty, with access to an extensive set of modules.
