Abstract: Systems and methods of sending secured messages on decentralized networks are provided. A software application distributed and installed on a computer terminal that willing is able to participate in the system, where the computer terminal is interactively and dynamically connected to one or two decentralized peer-to-peer communication networks, using the Internet. One of the networks is used to advise about the presence of a message and the other is used to securely store the content of the messages. An alternative embodiment is to use only the decentralized storage system, if it can also acts as a Public Ledger network, with its native crypto-currency. The cryptographic keys of the first network are used to protect the content of the file and to derive where the messages will be stored on the decentralized storage network. In such networks, the transactions are handled by cryptographic mathematical algorithms, which are known to be identical across all users or participants of the same network.
