Create a minimal ~/.glcoin/glcoin.conf to set RPC credentials.
mkdir -p ~/.glcoin
cat > ~/.glcoin/glcoin.conf << EOF
rpcuser=glcoinrpc
rpcpassword=$(openssl rand -hex 32)
server=1
txindex=1
EOF
Launch glcoind and verify it's running.
glcoind -daemon
glcoin-cli getblockchaininfo
Hash any file and embed the proof on-chain with a single transaction.
# Hash a document
sha256sum document.pdf
# Anchor it on-chain (OP_RETURN)
glcoin-cli sendopreturn "$(sha256sum document.pdf | awk '{print $1}')"
