Double-check that a blockchain solution is actually capable of solving these issues. Then, decide whether you’ll need to migrate your current solution to a blockchain application or build an application from the ground up. Some businesses require an intermediary for data control and authentication. But for businesses that operate without a third-party solution, blockchain can provide total transparency and consensus validation. It also reduces the costs and delays that result from using an intermediary for transactions. Thus, the overall history of each transaction within the distributed ledger is visible by all members of the network.
