#### Mainnet
[Noise Framework](http://www.noiseprotocol.org/) handshakes will be used for mainnet. libp2p Noise support [is in the process of being standardized](https://github.com/libp2p/specs/issues/195) in the libp2p project.
The [Libp2p-noise](https://github.com/libp2p/specs/tree/master/noise) secure
channel handshake with `secp256k1` identities will be used for mainnet.
Noise support will presumably include IX, IK, and XX handshake patterns, and may rely on Curve25519 keys, ChaCha20 and Poly1305 ciphers, and SHA-256 as a hash function. These aspects are being actively debated in the referenced issue (Eth2 implementers are welcome to comment and contribute to the discussion).
As specified in the libp2p specification, clients MUST support the `XX` handshake pattern and
can optionally implement the `IK` and `XXfallback` patterns for optimistic 0-RTT.
