11. Limitations of Blockchain

Although blockchain is a revolutionary technology, it's critical that it be understood and employed carefully. The following are some of the limitations of blockchain.

1. It is a very technically involved and potentially confusing concept. Even developing a good grip on the basics of blockchain can be difficult. Therefore, a high level of expertise is required to correctly understand what's occuring during a transaction.

2. Even the slightest error while structuring the smart contract may lead to catastrophic outcomes.

3. It requires a huge network of users to work effectively. Furthermore, the strength of the blockchain network depends on the strengths of its nodes, incentivized by the network itself. The networks that don’t provide high incentives are not as strong as the bitcoin network.

4. Sometimes, immutability of transactions can be a problem.

5. The scalability of the network is yet another issue in the blockchain. A single transaction involving bitcoin takes around at least 10 minutes.
