teleport

Lux Teleport Protocol is comprised of Multi-Party Compute (MPC) nodes which perform oracle operations and MPC signature on the bridge.

Features

Lux Teleport has the following features:

  1. Decentralized oracle operations using MPC
  2. Decentralized permissioning using MPC
  3. Zero knowledge transactions, signers don't know details about assets being teleported to and from supported chains.

Installation

Clone the repository on all signers.

git clone https://github.com/luxfi/teleport

Install rust and mongoDB on all nodes.

Run the installer file.

chmod 777 install.sh
./install.sh

Set up mongoDB and the Teleport data store.

pico /etc/mongod.conf

comment out the following:

security: authorization: enabled

mongod --config /etc/mongod.conf
mongo
use bridge
db.createUser(
  {
    user: "lux",
    pwd: "your-secure-password",
    roles: [ { role: "readWrite", db: "bridge" },
             { role: "read", db: "reporting" } ]
  }
)

Stop mongod, uncomment:

security: authorization: enabled

Then restart mongodb.

mongod --config /etc/mongod.conf

You could also run mongod using pm2 as

pm2 mongod --config /etc/mongod.conf

Run Keygen

Manually do the following on all signers:

cd ./target/release/examples/

Start an SM server

./gg20_sm_manager

That will start an HTTP server on http://127.0.0.1:8000. Other parties will use that server in order to communicate with each other. Note that communication channels are neither encrypted nor authenticated. In production, you must encrypt and authenticate parties messages. Set up your own endpoint to do this. Add your signing manager to: "SigningManagers".

If you have a 3 party MPC node network, open 3 terminal tabs for each MPC TeleportNode. Run:

  1. ./gg18_keygen_client http://yourIP1:portNumber keys1.store
  2. ./gg18_keygen_client http://yourIP1:portNumber keys2.store
  3. ./gg18_keygen_client http://yourIP1:portNumber keys3.store

Each command corresponds to one party. Once keygen is completed, you'll have 3 new files: keys1.json, keys2.json, lkeys3.json corresponding to local secret share of each party.

Add these your your SettingsMPC.json under "KeyStore"

Setup an endpoint with NGINX to run your node. Adding additional teleport networks are created by updating SettingsMPC.json. This repo will update Settings.json with new chains.

Run the Lux Teleport node with:

npm run node

The Teleport App can be used to interact with this MPC network.
