# Direct Connections
We propose a method of using Onionr's block sync system to enable direct connections between peers by having one peer request to connect to another using the peer's public key. Since the request is within a standard block, proof of work must be used to request connection, and in addition neither party knows the other's .onion or .i2p hostname, let alone IP address. If the requested peer is available and wishes to accept the connection,Onionr will generate a temporary .onion address for the other peer to connect to. Alternatively, a reverse connection may be formed, which is faster to establish but requires message brokering instead of a standard socket.

The benefits of such a system are increased privacy, and the ability to anonymously communicate from multiple devices at once. In a traditional onion service, one's online status can be monitored and more easily correlated.
