What are the barriers for blockchain adoption?

These roadblocks could be viewed as limits that need to be addressed and investigated to improve the company’s innovation to accelerate blockchain adoption.
The cost barrier - When compared to a centralized system, the necessity to replicate data across numerous nodes will almost certainly increase the costs of preserving this data. The data must be appropriately saved with numerous backups so that even a little replication fault will not occur. To do so, the system will require a certain level of redundancy, which will be achieved by duplicating databases.
Latency and scalability - duplicating data across many nodes pose scalability issues because all transactions must be broadcasted and recorded in all nodes, creating a bottleneck in transaction volume. Even Bitcoin can only do seven transactions per second.
Regulations and compliance - Financial organizations and banks may be hesitant to adopt blockchain because it is difficult to explain to authorities how data is transferred across blockchain participants. Regulators in these businesses are also more risk conservative, and regulatory frameworks in many nations are many years behind.
