Goal

Connect a new node to the Hegemon testnet, verify it is on the canonical chain, and mine only after sync completes.

Defaults

• Approved public seed list: hegemon.pauli.group:31333
• Chain spec: config/dev-chainspec.json
• Chainspec SHA-256: 7aca48651ea2aeb4cf59793a9ec1f1c3f0a7147d6b6cd279cdaf2d93bea84f55
• Genesis hash: 0x85cd1fb8f6a79054a672e6247da1c21e75c2fd2ef9e78d195de85f5846b935cf
• RPC port: 9944
• P2P listen: /ip4/0.0.0.0/tcp/30333

Steps

1. Ensure binaries exist (fresh clones must run make setup and make node):
   • make setup
   • make node
   • cargo build --release -p walletd
2. Verify the shared chainspec matches the boot node. Do not use --chain dev.
   • shasum -a 256 config/dev-chainspec.json
   • Expected: 7aca48651ea2aeb4cf59793a9ec1f1c3f0a7147d6b6cd279cdaf2d93bea84f55
3. Create or open a wallet and export the shielded mining address:
   • export HEGEMON_MINER_ADDRESS=$(printf '%s\n{"id":1,"method":"status.get","params":{}}\n' "YOUR_PASSPHRASE"
     | ./target/release/walletd --store ~/.hegemon-wallet --mode open
     | jq -r '.result.primaryAddress')
4. Start the node with the shared chainspec and seed:
   • HEGEMON_MINE=1
     HEGEMON_SEEDS="hegemon.pauli.group:31333"
     HEGEMON_MINER_ADDRESS="$HEGEMON_MINER_ADDRESS"
     HEGEMON_PROVER_REWARD_ADDRESS="$HEGEMON_MINER_ADDRESS"
     HEGEMON_PQ_STRICT_COMPATIBILITY=1
     ./target/release/hegemon-node
     --dev
     --base-path ~/.hegemon-node
     --chain config/dev-chainspec.json
     --listen-addr /ip4/0.0.0.0/tcp/30333
     --rpc-port 9944
     --rpc-external
     --rpc-methods safe
     --name "TestnetNode"
5. Monitor sync status and height. Mining pauses while syncing and resumes once caught up.
   • curl -s -H "Content-Type: application/json"
     -d '{"id":1,"jsonrpc":"2.0","method":"system_health"}'
     http://127.0.0.1:9944 | jq
   • curl -s -H "Content-Type: application/json"
     -d '{"id":1,"jsonrpc":"2.0","method":"hegemon_consensusStatus"}'
     http://127.0.0.1:9944 | jq
   • curl -s -H "Content-Type: application/json"
     -d '{"id":1,"jsonrpc":"2.0","method":"chain_getHeader"}'
     http://127.0.0.1:9944 | jq
6. If height stalls, check peers and genesis hash:
   • curl -s -H "Content-Type: application/json"
     -d '{"id":1,"jsonrpc":"2.0","method":"chain_getBlockHash","params":[0]}'
     http://127.0.0.1:9944 | jq
7. Sync wallet notes against the node RPC:
   • printf '%s\n{"id":1,"method":"sync.once","params":{"ws_url":"ws://127.0.0.1:9944","force_rescan":false}}\n' "YOUR_PASSPHRASE"
     | ./target/release/walletd --store ~/.hegemon-wallet --mode open

Notes

• All miners should use the exact same HEGEMON_SEEDS list to avoid accidental forks/partitions. Keep private peer IPs out of public docs.
• Keep host clock sync enabled (NTP/chrony). PoW import rejects future-skewed timestamps.
• If the genesis hash or chainspec differ, stop the node and wipe the base path before restarting.
• Keep RPC access locked down if you expose it beyond localhost.
