Performance
We concluded in the previous section that DLTs are more robust than traditional databases. But this fault-tolerant system comes with the cost of reduced performance. We have already come across the scalability issues faced by blockchain technology. This is due to the verification and other consensus mechanisms that are required to achieve decentralization. Bitcoin uses a Proof of Work (PoW) algorithm to achieve the consensus, which restricts the block creation time to 10 minutes. This will limit the rate at which transactions are added to the blockchain. Databases don't have any such restrictions with record insertions. Creating records in database tables is much faster than inserting transactions into blockchain.
