Beam is a future cryptocurrency that proposes an innovative change within the blockchain, granting the user a high level of privacy and confidentiality based on a "MimbleWimble" protocol.
The bitcoin like the rest of the cryptocurrencies were designed to perform transactions from anonymity, generating a random key both public and private, being the public key the address of our wallet through which we would carry out our transactions, making many users believe that it would be impossible to link them with their personal identity.
However, this is an erroneous idea, since among the large number of exchanges or transactions, there is always data that is uncovered, and since all transactions are stored, a simple data or key that remains in public domain would link the private identity of the user with his transactions.
It is a protocol published in 2016 by an anonymous author, suggesting a quite innovative and elegant design based on confidentiality within the blockchain. Its name derives from a reference to a spell of the famous saga of Harry Potter books.
It builds upon two concepts originally proposed by Greg Maxwell, namely Confidential Transactions and Transaction Cut.
A simple way to explain it would be to imagine that you give a message encrypted to X person of whom you possess a key to decrypt it and read the content when the right time comes.
in theory, mimblewimble would give more privacy to blockchain users by handing over a blinding and hiding factor within the transactions made.
Thi is a graphic example of how it works:
