What is Blockchain?


In simple terms Blockchain is a network of shared databases that support multiple writers and is synchronized in real time. This network is designed with a series of rules that clearly define the roles of each existing or new participant, the types of transactions between them and the kind of values that may be created or exchanged. Finally each change or transaction within this network will be chronologically written in an immutable record, meaning that while transactions may be changed, the record of that transaction and its correction can never be deleted.
