**4. The core value of blockchain in the industry**

After analyzing the results of different proofs of concept and the benefits provided, we could say that blockchain can bring a number of differential features to Industry 4.0.

Perhaps the most popular is the decentralization of processes and business models. Blockchain provides by definition the intermediation between two parties in a reliable way [24] that is why many processes and organizations whose main value is the intermediation between parties can be optimized thanks to blockchain technology. We will therefore see intermediaries that adopt technology to be more efficient and robust, thus being able to offer a better service at more competitive prices or consortiums of companies that invest in creating themselves platforms to manage their relationships without depending on current intermediaries.

At the same time, blockchain offers an unalterable record of the history of any asset or industrial good, so traceability on that record is natural for blockchain technology. In addition, this record can be shared with third parties in an exercise of transparency of their processes.

Blockchain offers a really efficient synchronization of processes; it provides us with a single consensuated vision of the information related to industrial assets and processes, something really important in cases where different players and information systems must be coordinated to achieve a common industrial objective.

It is a perfect synchronization technology, resilient to network microcuts or failures of the systems involved in the industrial process. These usual deficiencies of the traditional technologies generate incoherencies in the data and consequently incorrect decision-making due to a bad synchronization of the information shared between the collaborating systems.

Finally, we should emphasize the blockchain capacity for process automation thanks to being a reliable source of information by offering a synchronized, consensual, and unalterable record on which we can also have a non-repudiation of the information, as each participant signs each of their transactions as if it were a digital contract in pdf.

As we have already commented, automating our industrial processes based on information from third parties is really risky if the source is not reliable. Unlike the technologies that we usually handle, blockchain offers us that certainty, even an evidence that can be used to claim a third party if the recorded information is not real or accurate.
