I remember when I studied systems in the 90's. I had a class about PGP (Pretty Good Privacy), an asymmetric key encryption system to ensure privacy in emails. Its creator, Philip Zimmermann, was imprisoned for the development of this prototype, since for the USA: *Cryptography programs are classified as ammunition according to federal law and cannot be exported*. I assume that this technology is the basis of the asymmetric encryptions involved in the world of cryptocurrencies.

As the reason of this presentation, Zimmerman sought privacy and confidentiality.

For this motive I think that the creator of what we know as the strongest cryptocurrency, the Bitcoin, he never made himself known except through a pseudonym called Satoshi Nakamoto. Of course, others say that he is a time traveler from the future, but this is irrelevant.

The most important thing of all is that he was the founder of what we now know as blockchain. A large database distributed in thousands of interconnected nodes that allows you to create transactions with an electronic currency based on cryptography, to ensure security and validate the authenticity of them. However, in this great system, its biggest advantage (being transparent) is the worst of the failures.

Since all transactions are exposed to the public, which eliminates the privacy of users and their balance sheets. Governments, ad companies, and criminals can investigate the movements that a user has made in their electronic wallet through the blockchain.

Two years ago, a protocol called MimbleWimble was published, by an author who also maintained his anonymous identity (I suppose for the same reason as Nakamoto), which solves in an elegant way the problem of the confidentiality of transactions in the blockchain without sacrificing space or increasing the level of cpu or gpu required for mining.

This is where the Beam team comes in, who adopted the MimbleWimble protocol and developed a cryptocurrency and a blockchain capable of maintaining the privacy of users and their transactions.

# Features
<p>

* Beam does not store any type of confidential information of the user in its transactions.

* Beam does not have ICO.

* Beam uses Equitihash as a Proof-of-Work algorithm

* Beam implements MimbleWimble in C ++.

* Beam achieves scalability through its compact mining block size.

* Beam supports all types of transactions

# MimbleWimble

It is a protocol named based on a spell from the magical world of J. K. Rolling, which prevents the bewitched person to reveal the secrets. This protocol kills two birds with one stone.

1.	Hide amounts. This makes registered transactions confidential by not disclosing the amounts sent nor received. This is done by encrypting the quantities.

2.	Combining transactions. It allows you to add several transactions into a large transaction. Entering all the inputs (the 'from' part of the transaction) and all the outputs (the 'to' part). In this way the MimbleWimble block consists of 3 lists: the inputs, the outputs and the signatures created between the parties involved.

One of the peculiarities of the MimbleWimble protocol is that it prevents the nodes from seeking information from previous transactions; all they need is to verify that the outputs used are valid, so that the entire blockchain can be discarded. This greatly improves scalability.
