Chapter 1: When are Blockchain Libraries Useful?

Blockchain libraries provide a collection of functions and protocols that aid in the development and structuring of blockchain-based applications. Here are some situations where they are beneficial:

  1. Developing and deploying smart contracts: Blockchain libraries often come with detailed APIs that are useful for working with smart contracts, the computerized transaction protocols that execute the terms of a contract.

  2. Managing transactions: They aid in creating, signing, and managing transactions on the blockchain. This includes tasks like reading and interpreting raw transaction data.

  3. Interacting with the blockchain network: Libraries provide a structured and simple way to connect and interact with blockchain networks, facilitating tasks like querying the network status and monitoring events.

  4. Address and key management: They bring tools for managing private keys and addresses on the blockchain network, including functions for creating, storing, and recovering keys.

Chapter 2: What Functionalities do Blockchain Libraries Usually Have?

Here are some common functionalities typically found in blockchain libraries:

  1. Interface for blockchain nodes: Most blockchain libraries provide an interface to interact with blockchain nodes. This includes sending and tracking transactions, querying network status, and subscribing to network events.

  2. Cryptographic functions: Libraries usually include cryptographic functionalities to generate addresses, sign transactions, and handle private and public keys.

  3. Unit conversion: Libraries often bring built-in functions for converting tokens' unit measures, essential for correctly handling transactions.

  4. Contract interaction: They provide tools to create, deploy, interact with, and test smart contracts. This often includes contract abstraction for easier development and management.

  5. Encoding/Decoding tools: Libraries typically include utilities to encode and decode data to/from formats used in the blockchain ecosystem.

Chapter 3: Gotchas/Pitfalls to Look Out For

Working with blockchain libraries has its share of pitfalls, due to the intricacies of the blockchain. Here are some common gotchas to look out for:

  1. Transaction fee estimation: Accurately predicting transaction fees can be a challenge due to market fluctuation and other variable conditions on the network.

  2. Key management: Private keys need to be handled with extreme care, as losing them can result in losing access to the blockchain assets.

  3. Synchronization: Developing blockchain applications necessitates understanding blockchain synchronization - which can cause delays if not handled correctly.

  4. Best practices not always implemented: Not all libraries adhere to best security practices. Therefore, it’s crucial to vet the library’s security features before using it for production builds.

  5. Dependency issues: npm's dynamic dependency resolution can lead to unexpected version changes or the inclusion of outdated or insecure packages. So, dependencies should be carefully managed.

  6. Solidity version compatibility: Depending on the Ethereum Virtual Machine (EVM), there may be compatibility issues and subsequent errors when deploying Smart Contracts.
