Option A: Pre-built binary (recommended)
Download the latest release
curl -L -o autheod \
https://github.com/autheo-blockchain/autheo-chain-core/releases/latest/download/autheod
Make executable and move to PATH
chmod +x autheod
sudo mv autheod /usr/local/bin/
Option B: Build from source
Requirements: Go 1.23.12, GCC/Clang, Git, Make.
Install Go 1.23.12
wget https://go.dev/dl/go1.23.12.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.23.12.linux-amd64.tar.gz
echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
source ~/.bashrc
Clone the repository
git clone https://github.com/autheo-blockchain/autheo-chain-core.git
cd autheo-chain-core
Build
Standard build
With RocksDB
COSMOS_BUILD_OPTIONS=rocksdb make build
Verify and install
./build/autheod version # Expected: 1.0.8
make install
Initialize the node
autheod init <moniker> \
--chain-id autheo_2127-1 \
--home /path/to/node-home
Download the genesis file
curl -L -o /path/to/node-home/config/genesis.json \
https://raw.githubusercontent.com/autheo-blockchain/networks/main/mainnet/genesis.json
Bootstrap from a snapshot (optional)
wget https://snapshot.autheo.com/data_backup_latest.tar.gz
sudo systemctl stop autheod
rm -rf /path/to/node-home/data/
tar xzvf data_backup_latest.tar.gz
mv data/ /path/to/node-home/data/
After restoring from a snapshot, always restore your own priv_validator_state.json from a secure backup. Never use the state file from a public snapshot.
Troubleshooting
| Problem | Cause | Fix |
|---|
| Command not found | /usr/local/bin not in $PATH | export PATH=$PATH:/usr/local/bin |
| Permission denied | Binary not executable | sudo chmod +x /usr/local/bin/autheod |
| Exec format error | Wrong architecture binary | Check uname -m; use linux-amd64 for x86_64 |
| Version conflict | Old binary in PATH | Remove old binary before installing new one |
