Prerequisite

• Go 1.12+
• At least 150 GB storage space (estimated usage: ~15GB/month)

Instruction

Building the software

Run build.sh, or alternatively:

1. git clone https://github.com/cosmos/cosmos-sdk
2. cd cosmos-sdk
3. git checkout v0.34.6
4. make install tools
5. verify installation with gaiad version and gaiacli version, check that the version shown is 0.34.6

Running a node

1. gaiad init --chain-id "likechain-cosmos-testnet-1" YOUR_NODES_NAME
2. copy genesis.json as ~/.gaiad/config/genesis.json
3. modify ~/.gaiad/config/config.toml, replace persistent_peers="" with persistent_peers="[email protected]:26656"
4. run gaiad start

Generating Cosmos account and staking to become a validator

1. gaiacli keys add validator
2. follow the instruction to generate a Cosmos account, remember the passphrase and store the mnemonic phrase in a safe place
3. send us the address generated by the command above, or obtain it by gaiacli keys show validator -a
4. wait for us to send some coins into this account on the chain
5. run the following command to stake coins and become a validator:

gaiacli tx staking create-validator \
--amount AMOUNT_IN_nanolike \
--moniker YOUR_NAME \
--pubkey $(gaiad tendermint show-validator) \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--details "DESCRIPTION HERE" \
--min-self-delegation 1 \
--from validator \
--chain-id "likechain-cosmos-testnet-1"

Example:

gaiacli tx staking create-validator \
--amount 300000000000000nanolike \
--moniker chung \
--pubkey $(gaiad tendermint show-validator) \
--commission-rate 0.03 \
--commission-max-rate 0.1 \
--commission-max-change-rate 0.01 \
--details "Chung Wu, not Satoshi" \
--min-self-delegation 1 \
--from validator \
--chain-id "likechain-cosmos-testnet-1"
