Getting started

Setup

Connect to Sifchain

New Validators

1. Ensure you've installed the dependencies listed above.

2. Clone the repository:

git clone ssh://[email protected]/Sifchain/sifnode && cd sifnode

3. Checkout the latest testnet release:

git checkout tags/merry-go-round-3

4. Build:

make clean install

5. Generate a mnemonic:

rake "keys:generate:mnemonic"

6. Scaffold your node:

rake "genesis:sifnode:scaffold[merry-go-round, <moniker>, '<mnemonic>', [email protected]:26656, http://44.226.150.203:26657/genesis]"

• Replace <moniker> with the moniker (name) of your node.
• Replace <mnemonic> with the mnemonic phrase generated in the previous step.

This step will also output the keyring password, so please record this and the moniker somewhere secure.

7. Connect:

sifnoded start

and your node will start synchronizing with the network. Please note that this may take several hours or more.

Existing Validators

1. Checkout the latest testnet release:

git fetch && git checkout tags/merry-go-round-3

2. Build:

make install

3. Reset your local state (please take a backup of your keyring first):

sifnoded unsafe-reset-all

4. Download the new genesis file:

curl http://44.226.150.203:26657/genesis | jq '.result.genesis' > ~/.sifnoded/config/genesis.json

5. Update your persistent peers in the file ~/.sifnoded/config/config.toml so that it reads:

persistent_peers = "[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656"

6. Start your node:

sifnoded start

and your node will start synchronizing with the network. Please note that this may take several hours or more.

Become a Validator

You won't be able to participate in consensus until you become a validator.

1. Reach out to us on Discord to request some tokens.

2. Obtain your node moniker (if you don't already know it):

cat ~/.sifnoded/config/config.toml | grep moniker

3. Run the following command to become a validator:

sifnodecli tx staking create-validator \
    --commission-max-change-rate="0.1" \
    --commission-max-rate="0.1" \
    --commission-rate="0.1" \
    --amount="10000000000000000000rowan" \
    --pubkey=$(sifnoded tendermint show-validator) \
    --moniker=<moniker> \
    --chain-id=merry-go-round \
    --min-self-delegation="1" \
    --gas-prices="0.5rowan" \
    --from=<moniker> \
    --keyring-backend=file

• Replace <moniker> with the moniker (name) of your node.
