Blockchain is a technology whose propose is establishing trust in a distributed system. Problems of authentication, integrity, and nonrepudiation are solved by digital signatures. Digital signatures don't guarantee the time when the document was signed. For that reason, using blockchain in a financial transaction and other forms of the legal contract provides necessary security in the time. It is a perfect alternative to avoid cyber attacks and to guarantee the trust of any transaction, for example, bitcoin.

Good morning Alex Two weeks ago you were urgently requested to send us some updated files. On time delivery of a report to an important client depended on the reception of these files. The files arrived eight days later than requested and they were three months outdated. This situation was communicated to you upon the files reception. I was assured by the person in charge that the mistake would have been solved the following day. That happened six days ago and I have been waiting for those files ever since (desde entonces). In case they don´t arrive today, delivery won´t be done before the deadline and a penalty clause will be activated. Please respond asap.
