Sets up the Prysm consensus client for syncing with the Goerli testnet. This includes downloading the installation script, genesis file, generating a JWT secret, and starting the beacon chain. Consider checkpoint sync for faster synchronization.

```bash
mkdir prysm && cd prysm

# Download installation script
curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh

# Download the Goerli network genesis file
wget https://github.com/eth-clients/eth2-networks/raw/master/shared/prater/genesis.ssz

# Generate a 32 byte hex secret key for authentication, for e.g.
./prysm.sh beacon-chain generate-auth-secret
# Alternatively, `openssl rand -hex 32 | tr -d "\n" > "jwt.hex"

# Start Prysm beacon chain.
# NOTE: For Goerli testnet, add `--prater` flag
./prysm.sh beacon-chain --http-web3provider=http://localhost:8551 --jwt-secret=/path/to/jwt.hex --genesis-state=./genesis.ssz
