Scalability problems occur because of restrictions in block dimensions, block processing times and resource-intensive consensus mechanisms. This is often why novel approaches — for example layer two scaling methods, sharding and option consensus algorithms — are now being produced.
Voting As described over, blockchain could facilitate a contemporary voting system. Voting with blockchain carries the probable to remove election fraud and boost voter turnout, as was tested from the November 2018 midterm elections in West Virginia.
