Blockchain Developer Certification Practice

What main challenge do Ethereum developers face due to its design philosophy?

1. Ensuring complete immutability of the blockchain.

2. Building applications without any bugs.

3. Rebuilding infrastructure as the platform evolves.

4. Providing guarantees for transaction finality.

The correct answer is: Rebuilding infrastructure as the platform evolves.

The main challenge that Ethereum developers face due to its design philosophy relates to rebuilding infrastructure as the platform evolves. Ethereum was designed to be a flexible and adaptable environment for decentralized applications (dApps) and smart contracts. This adaptability is beneficial as it allows developers to create innovative solutions and improve upon the existing technology. However, this flexibility also means that the underlying infrastructure is subject to changes and upgrades, such as the transition from Ethereum 1.0 to Ethereum 2.0, which introduces proof-of-stake and sharding. As the platform evolves, developers must continuously update their applications and potentially redesign their systems to align with new standards and functionalities, which can be a significant challenge. This need for constant adaptation can lead to increased development time, potential disruptions in service, and a steep learning curve for developers who must keep pace with these changes. Other aspects, such as ensuring complete immutability, building bug-free applications, and providing guarantees for transaction finality, while important, are not as directly tied to the design philosophy of Ethereum in the context of ongoing platform development. These challenges exist in various forms across all blockchain technologies but are not uniquely related to the evolution of Ethereum’s underlying framework.
