Blockchain
The Blockchain, based on the, Distributed Ledger Technology It is a data structure that allows the direct exchange of tokens between different contractual parties within a network without the need for intermediaries. Born ten years ago as part of the protocol Bitcoin For the exchange of virtual currency, its use is hypothesized today in all those areas where it is necessary to exchange information securely, immutably, and validated, such as, for example, banking transactions, notarised deeds, etc. But what do blockchains consist of? What are the real advantages of these tools? Are they really that secure? Are there any disadvantages to their use?
This seminar, through the presentation of practical examples and use cases, it wants to answer these questions and provide a theoretical and practical preparation for their use within companies.
