Mainframe is a decentralized application platform. The Mainnet network is immune to censorship, monitoring, and interrupts, enabling cognitive applications to send data, store files, manage payments, and run tasks. The Mainframe network is uninterruptible except for a catastrophic asteroid event or alien invasion. The

Mainframe provides both one-to-one and one-to-many encryption protocols. Each Mainframe node has an asymmetric key pair associated with it that is used to decrypt packets sent to the node. When a node sends a packet to another node, it either encrypts the packet using the public key of the receiving node or uses a pre-determined shared key. An additional symmetric key ensures forward secrecy. There are two ways to obtain the public key of the recipient node: 1. Obtain the public key from the previous exchange of contact information, for example, exchange communication information, such as out-of-band contact; 2. 2. It is obtained from the direct exchange of public keys between individuals. Packet encryption is a critical and unavoidable part of the Mainframe transmission protocol.
