What is Blockchain?
A blockchain is a data structure that allows for creating a digital ledger of transactions and sharing them across a distributed network of computers. You can store different information in a blockchain, but thus far, the most common use has been as a record of transactions.
Why should you learn Blockchain?
Blockchain is a universal infrastructure that can store or transfer information anywhere worldwide. Furthermore, the technology integrates seamlessly with existing systems and processes, making it viable for global implementation and expanding your international career prospects.
