Brief history

It is a recent technology that is popularized with Bitcoin. By representing an immutable record of transactions (without the mathematical possibility of altering its content), it was popularized as a book of accounts of a decentralized “cryptocurrency”.

Monetary units (or value deposits), they are only one of the multiple cases of use of this technology of increasing acceptance and use.

When to use blockchain?

When we want maximum security of information integrity (without being directly responsible for this), that is, proof of non-modification.

In scenarios that have to be demonstrated in a cryptographic way (with legal validity), that the data has not been altered in any way by its owner. This makes sense as a guarantee:

1. Before external clients or authorities (audit, administrations), to provide transparency to the process.
2. In consortia of multiple participants outside the company , where everyone has access and power over the data.

Have a perfect traceability of who has done what with the data, and maintain the original values ​​in an easily identifiable way, gives a reliability to the business process.
