Code bloat occurs when software developers include extraneous code that does not contribute to the core functionality of an application. This might happen due to poor design decisions, lack of planning, or simply because features are added over time without proper evaluation of their necessity. Code bloat can lead to increased load times, reduced performance, and a more complex codebase that is challenging to maintain, modify, or debug. In the context of web3 and decentralized applications, code bloat can also affect the efficiency and transaction speeds of smart contracts on the blockchain.
