Blockchain technology is becoming increasingly important in the world of technological innovations. In fact, the number of scholars, technology experts and enthusiasts who get involved full-time in the development of this technology continues to grow.
One of these is Riccardo Casatta, the protagonist of the seventh video interview in the Insideblockchain playlist. He, having foreseen the revolutionary facets that blockchain could have on society, has decided to leave his job to fully devote himself into deepening his knowledge of this technology and its potential developments.
In 2015, Casatta launched Eternity Wall a project that fully exploits Blockchain feature of immutability. This project aims to create a simple interface that users can exploit to save text messages. The peculiarity of this “eternal wall” is that messages are not saved on a company-owned server but on a blockchain. This means that the messages can not be deleted or lost.
The “eternal” message creation was only the first application of the technology by Casatta and his collaborators. Their project was then extended to the use of blockchain properties of durability and incensurability to achieve the timestamp and thus guarantee the integrity and immutability of any type of data, not just message text.
Timestamping is the application of a timestamp to a given event or data. In the Blockchain the “Trusted Timestamping” is about securely creating and / or modifying a document. It is a tool that allows interested parties to know, undoubtedly, that a document exists at a given date and time.
Asked about the future of this technology, Casatta replies that he does not know what will happen, but he is sure it will be a future full of positive developments. He continues to say that he is well aware that in order to accept the revolutionary culture Blockchain technology introduced, a transformation of mentality into society must take place. This stresses the need for training and information on this subject.
