Relay Telecom

DEMO: https://relay.netlify.com

(Note: the demo uses http://relay-relay.herokuapp.com/ as its relay found here https://github.com/RelayTelecom/relay and may go into standby. Any http request, such as visiting the page, should force heroku to keep it deployed)

This project aims to provide a platform for decentralized voice communications using ethereum.

Whisper is used to locate an address and thereafter negotiate a symmetric encryption key. The clients locate a nearby relay and, using that encryption key, send and receive each other's audio data through a high throughput relay.

Relays advertise themselves over whisper.

This technology will pair nicely with payment channels like Raiden as usage can be billed at the per-second level. This is out of scope of our hackathon submission but further work would include it.

Building

yarn install

yarn start

Running

Call an ethereum address. If they are also on the web page it will ring and present an accept/decline dialog.

Hackathon Checklist

• Basic interface
• Relay read-from-client buffer
• Client play-from-relay
• Fork Status to allow microphone
• Fork Token to allow microphone
• Whisper negotiation (Whisper is iffy right now, we proxied the functionality using websockets here: https://github.com/RelayTelecom/whispersocket)

Future Work

• Client side encryption. The framework is in place but the implementation is not.
• Whisper rework when the protocol is finalized
• Token/Status natively listen for these whisper messages and ring the phone, even when users are not on the page.
• web3.eth.sign! Status and Token don't support this key operation to off-chain identification.

Judges

You can use the Status web client for making calls; however, the audio quality is lacking. For the best audio quality, we recommend using chrome on a non-mobile device with metamask.

For the changes to status, see https://github.com/RelayTelecom/status-react and its dependency, https://github.com/RelayTelecom/react-native-webview-bridge

For our Token Android apk see: https://github.com/RelayTelecom/token-android-client

We know that the encrypting, encoding, transfering, decoding, and decrypting of audio data can be improved, but it is working!
