fairyring is a Cosmos SDK blockchain that leverages identity-based encryption (IBE) to enable pre-execution privacy on Cosmos SDK app-chains. fairyring consists of two main components, a blockchain purpose-built for management of decryption keys in a decentralized manner, as well as a Cosmos SDK module that other app-chains can use to integrate with fairyring.

1. Building fairyring

make build

2. Installing the fairyringd

make install

3. Running fairyringd

fairyringd

1. After building the fairyring executable and before running the script, make sure you have previous node data removed, to remove the data, run the following command

rm -rf ~/.fairyring

2. Then, run the following script to setup the node

./setup.sh <moniker>

• moniker can be any string you want, is the nickname of your node

3. Collect all the gentxs and create the new genesis

fairyringd collect-gentxs

4. Run the chain by

fairyringd start

1. Build docker image

docker build -t fairyring .

2. Setup validator

docker run -it -p 1317:1317 -p 9090:9090 -p 26657:26657 -p 26656:26656 -v ~/.fairyring:/root/.fairyring fairyring setup.sh <moniker>

3. Create new genesis.json

docker run -it -p 1317:1317 -p 9090:9090 -p 26657:26657 -p 26656:26656 -v ~/.fairyring:/root/.fairyring fairyring fairyringd collect-gentxs

4. Start the validator

docker run -it -p 1317:1317 -p 9090:9090 -p 26657:26657 -p 26656:26656 -v ~/.fairyring:/root/.fairyring fairyring fairyringd start

1. Repeat step 1 - 2 on all the machines,

2. Run the following command for all the address created in other machine in the master validator:

docker run -it -p 1317:1317 -p 9090:9090 -p 26657:26657 -p 26656:26656 -v ~/.fairyring:/root/.fairyring fairyring fairyringd add-genesis-account <address> 100000000stake

3. Add all the gentx.json at ~/.fairyring/config/gentx/gentx-{node_id}.json from all the machines to master validator, then run the command on step 4

4. replace the old genesis.json with the new one created in master validator

5. Open config.toml at ~/.fairyring/config/config.toml on master validator and replace the IP Address & Port of the peers

6. Update the config.toml for all the other machine to include all the validator peers:

presistent_peers = "node_id@ip:port,node_id2@ip:port"

You can get the node id by the following command:

docker run -it -p 1317:1317 -p 9090:9090 -p 26657:26657 -p 26656:26656 -v ~/.fairyring:/root/.fairyring fairyring fairyringd tendermint show-node-id

7. Start the validator on all the machines

1. Follow step 1 - 2 on Run validator locally

2. Make sure you have enough coins in your account

3. Replace the genesis.json and config.toml

4. Send the fairyringd tx staking create-validator command with the address created to become validator, for example:

docker exec -it $(docker ps --latest --format '{{.ID}}') fairyringd tx staking create-validator \
  --amount=100000000stake \
  --pubkey=$(fairyringd tendermint show-validator) \
  --moniker="choose a moniker" \
  --chain-id="fairyring" \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1000000" \
  --from validator_account

5. Start the validator

Create pub key

fairyringd tx keyshare create-latest-pub-key <pub-key-in-hex>

Register as a validator

fairyringd tx keyshare register-validator

Submit a KeyShare

fairyringd tx send-key-share <keyshare-in-hex> <commitment-in-hex> <keyshare-index> <keyshare-block-height>

Submit aggregated key share

fairyringd tx pep create-aggregated-key-share <aggregated-key-share-height> <aggregated-key-share-in-hex> <public-key-in-hex>

Submit encrypted transaction

fairyringd tx pep submit-encrypted-tx <encrypted-tx-cipher-in-hex> <target-block-height>

Get all validators

fairyringd query keyshare list-validator-set

Get all broadcasted keyshares

fairyringd query keyshare list-key-share

Get specific validator

fairyringd query keyshare show-validator-set <Index>

Get specific keyshare

fairyringd query keyshare show-key-share <Validator> <BlockHeight>

Get all encrypted tx in state

fairyringd query pep list-encrypted-tx

Get all encrypted tx in state from a specific block height

fairyringd query pep list-encrypted-tx-from-block <blockHeight>

Get a single encrypted tx in state with a specific block height & tx index

fairyringd query pep show-encrypted-tx <blockHeight> <index>

It is recommended to run fairyringclient so that validator registration and key share submissions are automated.

It is recommended to run fairyport to listen to broadcast keyshare events and aggregate the keys in each block.

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

Ignite CLI 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 Ignite front-end development.
