Rep

Rep is a blockchain built using Cosmos SDK and Tendermint and created with Ignite CLI. Functioning as a rollup chain, it operates seamlessly on Celestia.

Overview

Rep allows users to create their own identities, update them and '+rep' or 'like' other users, thereby enhancing their reputation. The reputation of a user is determined by the number of 'likes' they receive. A comprehensive list of all identities within the chain can also be viewed.

Features

• Users have the capability to create their own identity on the Rep chain.
• The identity can be customized with a name and description. Moreover, the creator retains the power to update the identity information at any point.
• Once an identity has been established, users can enhance other user's reputation or '+rep' by 'like' other users.
• The reputation of a user can be gauged by the count of 'likes' they have garnered.
• A comprehensive list of all identities within the chain is also accessible for viewing.

Pre-requisites

• You have installed Go version 1.19 or higher
• You have installed Ignite CLI v0.25.1.

You can install it by running the following commands:

git clone https://github.com/ignite/cli.git
cd cli && git checkout v0.25.1
make install

• You have installed jq.

You can install it by running the following commands:

apt update
apt install jq -y

Start on local devnet

Run local devnet using docker

docker run --platform linux/amd64 -p 26650:26657 -p 26659:26659 ghcr.io/rollkit/local-celestia-devnet:v0.9.1

This will start a local devnet, the rpc port is 26650, gateway api port is 26659. Wait few seconds till it get 3 blocks+

Start rep chain

bash init-local.sh

Start on blockspacerace testnet

If you are running testnet on local machine

bash init.sh

If you are running testnet on remote machine

bash init.sh <your light node gateway url>

e.g. http://x.x.x.x:26659 Note: Ensure that the account of your light node has enough balance to pay PFB transactions.

Examples

Create an identity

repd tx rep create-user  rep-key hello  --from rep-key --keyring-backend test --chain-id rep-1 -y

This creates an identity with uid as 0. To query this identity, run:

repd query rep show-user 0

user:
  description: hello
  name: rep-key
  point: "0"
  uid: "0"
  wallet: rep1t0zgm4weu59uxmp22f0qedfft5l0djgt73lak9

Note: One address can only create one identity, Attempting to create another identity using the same address will fail.

Update an identity

 repd tx rep  update-user  rep-key "updated my user" 0  --from rep-key --keyring-backend test --chain-id rep-1 -y

To query the updated identity, run:

repd query rep show-user 0

user:
  description: updated my user
  name: rep-key
  point: "0"
  uid: "0"
  wallet: rep1t0zgm4weu59uxmp22f0qedfft5l0djgt73lak9

Note: Only the owner of the identity can update it. Attempting to update an identity using a different address will fail.

Try to update the identity using a different address:

repd tx rep  update-user  rep-key "updated my user" 0  --from rep-key-2 --keyring-backend test --chain-id rep-1 -y

Like other user

To like another user, first create a new identity:

repd tx rep create-user  user2 hi  --from rep-key-2 --keyring-backend test --chain-id rep-1 -y

rep-key-2 has created an identity, uid is 1.

We can use rep-key's identity to like rep-key-2's identity

repd tx rep like  1 --from rep-key --keyring-backend test --chain-id rep-1 -y

To query the identity of rep-key-2

repd query rep show-user 1

user:
  description: hi
  name: user2
  point: "1"
  uid: "1"
  wallet: rep1fkq8jyke9axxc2u045k2p35rercgnuj82elrny

We can see the point of user2 is 1, it means user2 has got 1 like.

Note: One address can only like one identity once, if you try to like the same identity again, it will fail.

Try to use rep-key to like rep-key-2's identity again

repd tx rep like  1 --from rep-key --keyring-backend test --chain-id rep-1 -y

Show all identities

repd query rep list-user

pagination:
  next_key: null
  total: "2"
user:
- description: updated my user
  name: rep-key
  point: "0"
  uid: "0"
  wallet: rep1t0zgm4weu59uxmp22f0qedfft5l0djgt73lak9
- description: hi
  name: user2
  point: "1"
  uid: "1"
  wallet: rep1fkq8jyke9axxc2u045k2p35rercgnuj82elrny

We can see there are two identities in the system. The first one is rep-key, the second one is user2(created by rep-key-2). user2 has got 1 like.
