MANTA NODE

This repo is a fresh FRAME-based Substrate node, forked from substrate-developer-hub/substrate-node-templte 🚀 It links to pallet-manta-dap for all Manta-APIs. See pallet-manta-dap/readme for more details.

Howto Run Manta Node

make init
make run

You will need to use manta front end to interact with this node.

Demo

Setup

1. run a Manta node locally
2. run a manta-front-end locally (require node.js with version > 12.0):

   git clone https://github.com/Manta-Network/manta-front-end.git
   cd manta-front-end
   yarn install
   yarn start 

   you will see an minimal front-end interface like the following:

Step 1: Create basecoin

Now we create a basecoin with 2000000 supply.

Step 2: Mint a 10 unit worth private coin 1

Here, we use pre-computed values of commitment, s, and k.

• s: xsPXqMXA1SKMOehtsgVWV8xw9Mj0rh3O8Yt1ZHJzaQ4=
• k: +tMTpSikpdACxuDGZTl5pxwT7tpYcX/DFKJRZ1oLfqc=
• commitment (cm): XzoWOzhp6rXjQ/HDEN6jSLsLs64hKXWUNuFVtCUq0AA=

you can see the newly minted private coin in the ledger:

Step 3: privately transfer coin 1 to coin 2

Now, we make a private transfer. This will generate a new UTXO, coin 2. We are also using pre-computed values:

• merkle_roots: q5VhDl/WxjeemZ/2ivGmiuOTFMEazcqEFk5ESISngso=
• old sn: jqhzAPanABquT0CpMC2aFt2ze8+UqMUcUG6PZBmqFqE=
• old k: +tMTpSikpdACxuDGZTl5pxwT7tpYcX/DFKJRZ1oLfqc=
• new k: 2HbWGQCLOfxuA4jOiDftBRSbjjAs/a0vjrq/H4p6QBI=
• new commitment: 1zuOv92V7e1qX1bP7+QNsV+gW5E3xUsghte/lZ7h5pg=
• encrypted transfer amount: UkNssYxe5HUjSzlz5JE1pQ==
• proof: Dhs0fgdEpE1SfBGIn5HpD22YvzPZKsLKMBPwT9QRe/BcuqnQuyr0oUHb7lNS/WoIPD/H348KI+e6eMcNa2nYLN5AqH/ZmXz7p2nrwUsHJVOYnFDuH2zEAcZi0hTPTN0HEiiXtYEBmUSt52xDehRSw/yCXY6AFvlQzXvMWdXq2SF2zRh93Rs9pQyO/3e7QLyMffIMeeAbx580PsJJELPrSB9x+a99l/4z8NW0YlBUwzt90uFL1bnEcp+B1gxXjpAD

Step 4: reclaim (forfeit) coin 2 (10 unit) to public coin

Using pre-computed values.

• merkle root: HMaIZu0QCE4s5fYiOpU3ouQE0m7PT4rBNsmMskIi50c=
• old sn: bwgOTJ8nNJ8phco73Zm6A8jV0ua6qsw9MtXtwyxV7cQ=,
• old k: 2HbWGQCLOfxuA4jOiDftBRSbjjAs/a0vjrq/H4p6QBI=,
• proof: 7+PY3Z5vL33hTY7w3HHLsvCCiICwtvQ6h6J2vt/y5ZteyJSj0LWbkwHaKlA+6/SUkKUxEyVox6bwXsakFRPrfuTfRmw2FAoVZCUzSKMqkKoFcj9WwskAnyYvnu1De7ARucNI8FFvGOhcejaPyWUu7VAH+y2iJz4irKU+vnwXqc5QKoPmA8m67Kyor4i+3PSL/tmTuVblLt8bmHjFbXhvicxdAbnKX33W36Ucg7nYOns4yC1h+ILO4llwUp4tOR6Y

Now, you succesfully reclaim coin 2 to public!
