Validator Information

ā€‹
Prerequisites

  • Git
  • Go 1.23+ and jq (native run)
  • Docker 24+ and Docker Compose (docker run)
  • macOS or Linux

ā€‹
Setting up Local Testnet

ā€‹
Clone the Repo

Clone the repository and navigate to the base directory: 
git clone https://github.com/mocachain/moca.git

# checkout stable version a382e3cĀ 
git checkout tags/v1.2.0-rc2

ā€‹
Deploy Single Node network.

ā€‹
1. Build the binaries

make build

# run ./build

# Otherwise...
# If gcc/ledger is not installed disable ledger support for build
# LEDGER_ENABLED=false make build

ā€‹
2. Deploy single validator / storage provider.

Start a single validator network with one Storage Provider: 
bash deployment/localup/localup.sh all 1 1
This initializes, generates genesis, and starts the node(s). Keys and data live under:
  • deployment/localup/.local/validator0
  • deployment/localup/.local/sp0
Ports and services:
  • Tendermint RPC: http://127.0.0.1:26657/status
  • EVM RPC: http://127.0.0.1:8545
  • REST API (LCD): http://127.0.0.1:1317
  • gRPC: 127.0.0.1:9090
šŸŽ‰ Your local testnet is now setup for your testing!

3. Interact with the chain

Here are some examples of how you can interact with the running services above. 
# Check node is producing blocks
curl -s localhost:26657/status | jq '.result.sync_info.latest_block_height'

# Show dev account (preloaded by the script)
./build/mocad keys show devaccount -a --keyring-backend test --home deployment/localup/.local/validator0

# Query bank balance of that address (replace ADDR with an address)
./build/mocad query bank balances ADDR --node tcp://127.0.0.1:26657

# Send EVM RPC requests
curl -s -X POST localhost:8545 -H 'content-type: application/json' --data '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

ā€‹
4. Stop/reset

If you need to stop/reset the chain here are the commands below: 
# Stop all localup-started nodes
bash deployment/localup/localup.sh stop

# Recreate from scratch (init + genesis + start)
bash deployment/localup/localup.sh all 1 1
