Cases when Ethereum blockchain (ETH) does not work

1. Network Congestion: Ethereum blockchain may experience congestion during periods of high demand, leading to slower transaction confirmations and higher fees. This congestion can occur due to popular applications or events that result in a surge of activity on the network.
2. Smart Contract Bugs: Smart contracts deployed on the Ethereum blockchain can contain bugs or vulnerabilities that can lead to unintended consequences. These bugs may allow hackers to exploit the contract and potentially steal funds or disrupt the functionality of the contract.
3. 51% Attacks: Like other blockchain networks, Ethereum is susceptible to 51% attacks where a single entity or group gains control of the majority of the network’s mining power. This can potentially allow them to manipulate transactions, reverse transactions, or double-spend coins.
4. Hard Forks: Ethereum has undergone several hard forks in its history to implement major upgrades or resolve issues. During a hard fork, the blockchain splits into two separate chains, creating a temporary disruption. Users need to ensure they are on the correct chain after a hard fork to avoid any issues.
5. Gas Price Volatility: Fees for transactions and smart contract execution on the Ethereum blockchain are determined by gas prices. Gas prices can be volatile, especially during periods of high demand. This volatility can lead to unpredictable transaction costs and delays.
6. Scalability Challenges: Ethereum’s current design faces scalability challenges, especially during periods of high demand. As more users and applications join the network, the limited capacity of the blockchain can result in slower transaction processing times and increased fees.
7. Dependency on External Oracles: Smart contracts on Ethereum can rely on external oracles to fetch real-world data. If these oracles are compromised or provide incorrect information, it can affect the accuracy and integrity of the smart contract’s execution.
8. Regulatory and Legal Challenges: Ethereum, like other blockchain networks, operates within a legal and regulatory framework that can vary across different jurisdictions. Changes in regulations or legal challenges can impact the usability and acceptance of Ethereum in certain regions.
