Hegemon Testnet Join

Goal

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

Defaults

• Boot node: hegemon.pauli.group:30333
• Chain spec: config/dev-chainspec.json
• Genesis hash: 0xcaa718106d1530705c53a99628d929cd78d47a0bf06b177aa4853962b47c637d
• 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
3. Create or open a wallet and export the shielded mining address:
   • export HEGEMON_MINER_ADDRESS=$(printf '%s\n{"id":1,"method":"status.get","params":{}}\n' "YOUR_PASSPHRASE"
     | ./target/release/walletd --store ~/.hegemon-wallet --mode open
     | jq -r '.result.primaryAddress')
4. Start the node with the shared chainspec and seed:
   • HEGEMON_MINE=1
     HEGEMON_SEEDS="hegemon.pauli.group:30333"
     HEGEMON_MINER_ADDRESS="$HEGEMON_MINER_ADDRESS"
     ./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

Notes

• 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.
