A framework is a foundational structure, or a set of tools, libraries, and best practices, that facilitates the development of software applications in a structured and efficient manner.

Blockchain being one of the hottest areas when it comes to tech, really needs more user facing applications with great user experiences to succeed and for any application to have great user experience the development needs to be user centric which is tough to achieve with the default development tool of Blockchain Nodes.

Hence in this blog we will explore the world of Blockchain App Development Frameworks and all they have to offer, we will see what blockchain frameworks are, what are some of the best blockchain frameworks and what makes them stand out in a crowded blockchain framework list

Why do we need Blockchain Frameworks?

The road from understanding the theoretical potential of blockchain to creating functional applications is fraught with technical challenges ranging from the complex design of Node systems to the technical challenges of maintaining a huge ledger. This is where blockchain frameworks step in as essential enablers, smoothing the path for developers and enterprises alike.

What Are the Types of Blockchain Frameworks? 

Types of Blockchain Framework varies based on the use cases and can range from Frameworks to build private or public blockchains, to Frameworks for Smartcontracts and FrameworksHere’s few thing that Blockhains Frameworks can help a developer with : 

1. Blockchain Development Frameworks : Blockchain Development Frameworks are akin to a treasure chest for developers venturing into the decentralized world of blockchain. They provide a structured environment equipped with tools and libraries tailored to streamline the process of developing, testing, and deploying blockchain applications.
   These can be further divided into :
   

1. On-Chain Data Management: Managing data on a blockchain, often referred to as on-chain data, requires a nuanced approach to ensure immutability and integrity. Blockchain frameworks offer tools and standards for effective on-chain data management, making it easier to store, retrieve, and interact with data without running big data operations.

2. Smart Contract Testing and Deployment Tools : Smart contracts are self-executing contracts where the terms are directly written into code. They are a cornerstone of many blockchain applications. Blockchain testing frameworks provide environments for developing, testing, and deploying smart contracts, ensuring they operate as intended in a secure and efficient manner.

2. Security Assurance: Blockchain security frameworks within the broader frameworks provide guidelines and tools for ensuring the security of blockchain networks, protecting against common threats and vulnerabilities.

3. Scalability and Performance Optimization: As blockchain networks grow, so does the demand for scalability and performance. Blockchain frameworks often come with solutions for scaling and optimizing the performance of blockchain applications, ensuring they remain robust as user numbers increase.
   
   
4. Blockchain Automation Framework : Blockchain Automation Frameworks are sets of tools and practices aimed at automating the deployment, maintenance, and operation of blockchain networks. They encapsulate best practices, standards, and automation scripts to ensure smooth deployment and management of blockchain networks.
   
   
5. A Blockchain Based PKI Management Framework :  A blockchain-based Public Key Infrastructure (PKI) management framework is an innovative approach to managing digital identities and ensuring secure communications. Traditional PKI systems are centralized, but a blockchain-based PKI can provide a decentralized alternative, which can potentially offer improved security, transparency, and trust among participants.
   
   
6. Community and Ecosystem Support: Popular blockchain frameworks often have vibrant communities and ecosystems, providing a wealth of resources, extensions, and support for developers.
   
   
7. Cross-Platform Development: Many frameworks offer support for multiple programming languages and platforms, such as blockchain JavaScript frameworks, blockchain Python frameworks, and Node.js blockchain frameworks, facilitating a broader scope of blockchain application development.

Blockchain Development Frameworks in Depth 

Blockchain development frameworks are tools and libraries specifically designed to simplify the process of creating blockchain applications. They provide pre-built functionalities, templates, and best practices that can accelerate the development cycle, maintain consistency, and reduce the potential for bugs. Here are some notable blockchain development frameworks and their features:

Ethereum Smart Contract Development Frameworks:

1. Truffle: A popular Ethereum development framework that provides built-in smart contract compilation, linking, deployment, and binary management. It also offers automated testing and scriptable deployment.

2. Embark: Another Ethereum framework that facilitates dApp development, and supports decentralized communication and on-chain and off-chain storage.
   
   
3. Hardhat: While not exclusive to Binance Smart Chain (BSC), Hardhat supports BSC and facilitates smart contract development, testing, and debugging.

Blockchain App Development Frameworks: 

1. Tatum SDK: Tatum is a blockchain development platform that provides an SDK to ease the development process. It supports a variety of blockchain networks besides Ethereum, such as Bitcoin, Binance Smart Chain, and others.
   Tatum SDK simplifies the process of creating, deploying, and managing blockchain applications by abstracting some of the complexities involved in interacting with blockchain networks. It provides a unified API to work with multiple blockchains, enabling developers to focus more on the application logic rather than the underlying blockchain protocols.

2. Ethers.js: Ethers.js is a lightweight JavaScript library designed to interact with the Ethereum blockchain. It allows developers to work with Ethereum-based smart contracts and tokens, manage wallets, and make transactions easily. The library is designed to be compact, with a complete set of features to aid in the development of Ethereum-based applications.‍

2. Web3.js: Web3.js is another robust JavaScript library for interacting with the Ethereum blockchain. It provides a set of functions to communicate with a local or remote Ethereum node using HTTP, IPC, or WebSocket. With Web3.js, developers can send transactions, interact with smart contracts, and query blockchain data.
   

The choice of a blockchain development framework largely depends on the specific blockchain platform you're working with, the requirements of your project, and the developer experience of the Framework (Docs, Guides, Community etc).

These frameworks are some of the leading choices and options for people looking for javascript blockchain framework or node js blockchain framework or even open source blockchain framework, specifically Tatum with constant commitment to push open source development with the Extensions, Check more about Extensions here.

Centralized Risks of Blockchain Indexing Frameworks: A Necessity for DApp Development?

The centralized nature of Blockchain Frameworks risks like single points of failure and potential data manipulation, which could be detrimental in a decentralized ecosystem like DApps (Decentralized Applications).

However, they are often seen as a necessary risk for building DApps due to their role in simplifying blockchain interactions and accelerating development cycles. While decentralization is a core principle of DApps, the centralized risks associated with Blockchain Frameworks may be a trade-off developers are willing to make to bridge the technical gaps and propel the DApp ecosystem forward.

Why not use something like The Graph?

Where The Graph is another great solution to build web3 apps without risking too much in centralisation its still has the following tradeoffs like

1. Centralization Concerns: Despite The Graph's aim for decentralization, there exists a centralization risk where a few dominant indexers could potentially affect the protocol's overall robustness.
   
2. Dependency on Governance: The governance mechanism of the protocol holds a significant role in making decisions regarding protocol amendments and upgrades. It's crucial for developers and users to remain updated and actively participate in governance to shape the protocol's direction.
   
3. Network Fee Implications: The cost of querying data on The Graph network is a factor developers need to account for while designing and launching dApps.
   
4. Data Accessibility: The readiness of specific subgraphs may hinge on the activities of curators and the community's engagement. Lack of active curation for certain subgraphs could result in data being less accessible.

Which again makes most of the developers steering towards the solution which does compromise on decentralization but are otherwise great to build with. One way to mitigate the risks of centralisation is to have better Service Level Agreements and work with the leaders in space.

Now whether frameworks will be the same scenario in the following years? This couldn’t be said or predicted though the inherent reason for most of the frameworks to have centralized server is the huge data ledger that even with the lightest nodes that could run in a mobile phone or your smart watches, we may always have and hence we will have a need for a data provider who will query and processes the whole blockchain data and stores it for quick retrieval making complex queries possible like get all transactions of a wallet. Otherwise all the application builders would first need to build a big data solution to handle the terabytes of data for building any good consumer facing application.
