random

random is a blockchain built using Cosmos SDK and Tendermint and created with Starport.

Get started

Clone the repository and run:

starport chain serve

serve command installs dependencies, builds, initializes, and starts your blockchain in development.

Commands

Chain Commands

• randomd tx random create-random <multiplier> --from alice This transaction command will use multiplier as the max number from 0 to create a random value then sign and broadcast it on the network.

• randomd q random list-randomval This query command will list all the map index with values created through create-random command (Lists all the random values + required data).

• randomd q random show-randomval <index/key> This query command will show random value on the specific index/key which currently is created using message creator address,user request counter

• randomd q random list-userval This query command will list all the users and the count that show how many times they sent the create-random command which ran the vr (verifiable random) functions and broadcasts on the network. (lists all the message creators + the count that shows how many times they performed this)

• randomd q random show-userval <user_address> This _query_ will show the times user performed (create message) creat-random` (The time user created random value on this chain)

• randomd q random verify-values [pubkey] [message] [vrv] [proof] This query command will verify the values created using create-random command.

For example here: randomd q random verify-values c00b85aaff213896e1bce84bad8200e1ea5d90f7d341ca2774e95a9837651 c9f cosmos1064p2u6xaw4d5exwpesf2jv3vd7cr7m7lgxzc8,3 71e759d11bc846f01c54fa1ecf1f4dc2f3c11f4fd899d0cd2d965dc5a3eea835 9206 c9f cosmos1064p2u6xaw4d5exwpesf2jv3vd7cr7m7lgxzc8,3 71e759d11bc846f01c54fa1ecf1f4dc2f3c11f4fd899d0cd2d965dc5a3eea835 9206 d61cae688f7cfcc23964b8391392bed94778df2f3bf493022d3e244331019b1f4fef646148c1819c4f38e9dbc51fb07aa8060200e9a13b2dab7df1174 e09d7946722a4dbc85d5b19c02cb63883c12a496e9d1c3dd815b964bc8c175a271b

IBC Commands (Chain Commands+)

Configure the relayer when running for 2 local chains earth and mars (if you are following the tutorial from video [linked below])

starport relayer configure -a \
--source-rpc "http://0.0.0.0:26657" \
--source-faucet "http://0.0.0.0:4500" \
--source-port "random" \
--source-version "random-1" \
--source-gasprice "0.0000025stake" \
--source-prefix "cosmos" \
--source-gaslimit 300000 \
--target-rpc "http://0.0.0.0:26659" \
--target-faucet "http://0.0.0.0:4501" \
--target-port "random" \
--target-version "random-1" \
--target-gasprice "0.0000025stake" \
--target-prefix "cosmos" \
--target-gaslimit 300000

then starport relayer connect

• randomd tx random send-req-randomval random channel-0 5000 --from alice --chain-id earth --home ~/.earth

This transaction command will prepare and send packet with mulitplier field from (if you are using default settings and following video) chain Earth to chain Mars

• randomd q random list-sent-randomval

This query command will list all the values received by chain Earth (the chain that you sent packet with in this case).

• randomd q random list-timedout-randomval

This query command will list all the timedout packet information.

Configure

Your blockchain in development can be configured with config.yml. To learn more, see the Starport docs.

Launch

To launch your blockchain live on multiple nodes, use starport network commands. Learn more about Starport Network.

Web Frontend

Starport has scaffolded a Vue.js-based web app in the vue directory. Run the following commands to install dependencies and start the app:

cd vue
npm install
npm run serve

The frontend app is built using the @starport/vue and @starport/vuex packages. For details, see the monorepo for Starport front-end development.

Release

To release a new version of your blockchain, create and push a new tag with v prefix. A new draft release with the configured targets will be created.

git tag v0.1
git push origin v0.1

After a draft release is created, make your final changes from the release page and publish it.

Install

To install the latest version of your blockchain node's binary, execute the following command on your machine:

curl https://get.starport.network/genievot/random@latest! | sudo bash

genievot/random should match the username and repo_name of the Github repository to which the source code was pushed. Learn more about the install process.
