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:
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.
Managing transactions: They aid in creating, signing, and managing transactions on the blockchain. This includes tasks like reading and interpreting raw transaction data.
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.
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.
Here are some common functionalities typically found in blockchain libraries:
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.
Cryptographic functions: Libraries usually include cryptographic functionalities to generate addresses, sign transactions, and handle private and public keys.
Unit conversion: Libraries often bring built-in functions for converting tokens' unit measures, essential for correctly handling transactions.
Contract interaction: They provide tools to create, deploy, interact with, and test smart contracts. This often includes contract abstraction for easier development and management.
Encoding/Decoding tools: Libraries typically include utilities to encode and decode data to/from formats used in the blockchain ecosystem.
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:
Transaction fee estimation: Accurately predicting transaction fees can be a challenge due to market fluctuation and other variable conditions on the network.
Key management: Private keys need to be handled with extreme care, as losing them can result in losing access to the blockchain assets.
Synchronization: Developing blockchain applications necessitates understanding blockchain synchronization - which can cause delays if not handled correctly.
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.
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.
Solidity version compatibility: Depending on the Ethereum Virtual Machine (EVM), there may be compatibility issues and subsequent errors when deploying Smart Contracts.
