I want to connect 2 nodes via custom chain specification via Internet IP public

I. STEP 1: Create Aura and grandpa

--- NODE 01----

  1. Create Aura-01:
    Secret phrase:       glory icon taste syrup such guard correct occur coyote frequent thing water
      Network ID:        substrate
      Secret seed:       0x070c94ef16c1a629ddf6b9d1416fa2665e7d5f01bd2113e61a78c53f6e5cda87

      SS58 Address:      5CJxbavev61VDuLbyMErtE7PvjA8osHhDkv3gKttHsSZFMdJ
  1. Create Grandpa-01
    Secret phrase:       glory icon taste syrup such guard correct occur coyote frequent thing water
      Network ID:        substrate
      Secret seed:       0x070c94ef16c1a629ddf6b9d1416fa2665e7d5f01bd2113e61a78c53f6e5cda87

      Account ID:        0x8e34ea1bd11bd532427f82daae6aa3a855fdc948136753905a74796a5b7146c8
      Public key (SS58): 5FHANk2EkM6sTeGnkZ2HaRCj356NVWg4DSJag4gsz6Jupazt
      SS58 Address:      5FHANk2EkM6sTeGnkZ2HaRCj356NVWg4DSJag4gsz6Jupazt

---NODE 02-------------------

  1. Create Aura-02:
    Secret phrase:       praise scout author learn bounce funny pulp caution young collect whip limb
      Network ID:        substrate
      Secret seed:       0x16df58dcb530ece94270a6154c7d8ad1b3d4aebe69ce55ed2cfe620f6e357a1d
      Public key (hex):  0x16134c09a7818a590ebc5f9b336c22fe3d23e88e6449edbb996116449430be01

      Public key (SS58): 5CZeeFRsRSUweVkqZR3hDTN9khk3U3oa4rjaFg2S96WPpRhd
      SS58 Address:      5CZeeFRsRSUweVkqZR3hDTN9khk3U3oa4rjaFg2S96WPpRhd
  1. Create Grandpa-02:
    Secret phrase:       praise scout author learn bounce funny pulp caution young collect whip limb
      Network ID:        substrate
      Secret seed:       0x16df58dcb530ece94270a6154c7d8ad1b3d4aebe69ce55ed2cfe620f6e357a1d
      Public key (hex):  0x3612c18b4ae0e6b7e5b5bd79b5353cc20af70ba1302fe638884114ee0b9a7452
      Account ID:        0x3612c18b4ae0e6b7e5b5bd79b5353cc20af70ba1302fe638884114ee0b9a7452

      SS58 Address:      5DHc1oW2bBAfu46v5mxNu97iWohvEvsdT2TyaBirXuQzC18F

II. STEP 2: Node 01 Export the local chain specification to a file named customSpec.json

    ./target/release/node-template build-spec --disable-default-bootnode --chain local > customSpec.json

III. STEP 3: Node-01 Add Aura and Grandpa both of node into customSpec.json

IV. Convert customSpec to RAW

    ./target/release/node-template build-spec --chain=customSpec.json --raw --disable-default-bootnode > customSpecRaw.json

V.Share customSpecRAW file to node-02

Link RAW file

VI.NODE-01 Run:

    ./target/release/node-template \
    --base-path /tmp/node01 \
    --chain ./customSpecRaw.json \
    --port 30333 \
    --ws-port 9945 \
    --rpc-port 9933 \
    --telemetry-url "wss://telemetry.polkadot.io/submit/ 0" \
    --validator \
    --rpc-methods Unsafe \
    --name MyNode01

VII.NODE-01 Add key to Keystore with password 123456

./target/release/node-template key insert --base-path /tmp/node01 \
--chain customSpecRaw.json \
--scheme Sr25519 \
--suri '0x070c94ef16c1a629ddf6b9d1416fa2665e7d5f01bd2113e61a78c53f6e5cda87' \
--password-interactive \
--key-type aura


./target/release/node-template key insert --base-path /tmp/node01 \
--chain customSpecRaw.json \
--scheme Ed25519 \
--suri '0x070c94ef16c1a629ddf6b9d1416fa2665e7d5f01bd2113e61a78c53f6e5cda87' \
--password-interactive \
--key-type gran

VIII. NODE-01 verify key

ls /tmp/node01/chains/local_testnet/keystore

IX.NODE-02 run:

./target/release/node-template \
--base-path /tmp/node02 \
--chain ./customSpecRaw.json \
--port 30334 \
--ws-port 9946 \
--rpc-port 9934 \
--telemetry-url "wss://telemetry.polkadot.io/submit/ 0" \
--validator \
--rpc-methods Unsafe \
--name MyNode02 \
--bootnodes /ip4/171.245.164.166/tcp/30333/p2p/12D3KooWBNTdqMcbcE3gqNWtvKWZWsFnHaehtMtbiq3kVeUk3JSE \
--password-interactive

X.NODE-02 Add key to keystore with password 123456

./target/release/node-template key insert --base-path /tmp/node02 \
--chain customSpecRaw.json \
--scheme Sr25519 \
--suri '0x16df58dcb530ece94270a6154c7d8ad1b3d4aebe69ce55ed2cfe620f6e357a1d' \
--password-interactive \
--key-type aura


./target/release/node-template key insert --base-path /tmp/node02 \
--chain customSpecRaw.json \
--scheme Ed25519 \
--suri '0x16df58dcb530ece94270a6154c7d8ad1b3d4aebe69ce55ed2cfe620f6e357a1d' \
--password-interactive \
--key-type gran

XI. NODE-02 verify key store

ls /tmp/node02/chains/local_testnet/keystore

Result is both nodes can peer without producing and finalizing blocks. enter image description here

Also same problem with 3 nodes. Can anyone help me this issue? Thank you.

Grandpa works with atleast 3 nodes because its using voting system to finalize blocks

  • It would help to add reference to the docs for this for people to learn :)

Do not use "key insert". It does not work! Go to polkadot.js and use RPC Calls/Authors/Insert Keys.

Make sure to connect to the appropriate node while inserting their keys.

Make sure to purge also, you might have inserted invalid keys in there.

  • I try to purge then use RPC Calls/Authors/Insert Keys. -Keytype:Text = aura -suri: Text = glory icon taste syrup such guard correct occur coyote frequent thing water -publicKey = 0x0adf0e0405dbc259257c2eb6700d00849a94edf496872dbea5547d236a9aff00 (publicKey is publicKey hex, right?) -Keytype:Text = gran -suri: Text = glory icon taste syrup such guard correct occur coyote frequent thing water -publicKey = 0x8e34ea1bd11bd532427f82daae6aa3a855fdc948136753905a74796a5b7146c8 still same issue.

  • When I restart node-1 then have new error. GRANDPA voter error: could not sign outgoing message: Failed to sign GRANDPA vote for round 1 targetting 0x9b4ee454930c1cf0f52d592136a35c8c20ee15caa177b06f8e8502423fe5d004 2022-06-29 14:47:02 Essential task grandpa-voter failed. Shutting down service. Error: Service(Other("Essential task failed."))

  • A. 1. You must have two nodes to be able to run aura-gran consensus, 2. generate aura: subkey generate --scheme sr25519, generate gran: subkey inspect --scheme ed25519 <use-same-mnemonics-in-aura>, 3. Make sure that when you encode the keys you use the correct public hex for aura and gran

  • B. 1. For the second node, make sure to connect to the second node before your provide the aura and gran keys, 2. Follow the process of letter A.

  • You can check /tmp/node01/local_testnet/keystore for node01, after you put the keys.

  1. Authorized the aura and gran addresses for both nodes in the CustomSpec.json file.
#...
      "aura": {
        "authorities": [
          "5DG73DMGcRCdJD55tnMuzAfb9MkwKsgpW5ft7DBpnUxpW3Wg",
          "5GsYff9q6wdjt2hXcWyt6W9K7mctwDWpT8QJguMj2svuvnU9"
        ]
      },
      "grandpa": {
        "authorities": [
          [
            "5DfD6wftdWs3VqsajyEZMZjsBLk9jTZV5PfihZ3GFCe8YCu7",
            1
          ],
          [
            "5FqMQ2bbE3uFmrbiAz4J3Cr3QdEq8NL48BgkVQZYbxFhnf5k",
            1
          ]

        "key": "5DG73DMGcRCdJD55tnMuzAfb9MkwKsgpW5ft7DBpnUxpW3Wg"
      }
#...
  1. Create a bootnode (node01) shell script command:
# run-bootnode.sh
./target/release/node-template \
--base-path /tmp/node01 \
--chain ./customSpecRaw.json \
--port 30333 \
--ws-port 9944 \
--rpc-port 9933 \
--telemetry-url "wss://telemetry.polkadot.io/submit/ 0" \
--validator \
--rpc-cors all \
--ws-external \
--rpc-external \
--rpc-methods Unsafe \
--name MyNode01
  1. Create a node2 (node02) shell script command (the node id of the bootnode may change from time to time, please take note of that carefully):
# run-node2.sh
./target/release/node-template \
--base-path /tmp/node02 \
--chain ./customSpecRaw.json \
--port 30334 \
--ws-port 9945 \
--rpc-port 9934 \
--telemetry-url "wss://telemetry.polkadot.io/submit/ 0" \
--validator \
--rpc-cors all \
--ws-external \
--rpc-external \
--rpc-methods Unsafe \
--name MyNode02 \
--bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWAk2PkrAqmEaqGtGc8ieUARYWmTyJkimpndd1F1f3ZJWZ \
  1. Purge all db and keystore. Take note that if you restart your computer, your keystore also will be deleted.
$ ./target/release/node-template purge-chain --base-path /tmp/node01 
$ rm -rf /tmp/node01/chains/local_testnet/keystore
$ ./target/release/node-template purge-chain --base-path /tmp/node02
$ rm -rf /tmp/node02/chains/local_testnet/keystore
  1. Now run the two nodes i different terminal.
$ ./run-bootnode.sh
$ ./run-node2.sh
  1. Register the keys of the bootnode. bootnode/aura bootnode/gran

  2. Register the keys of node2. Make sure your polkadotJS is really connected to node2, if not this will not work. node2/aura node2/grand

  3. Check the keystore for each node

$ ls /tmp/node01/chains/local_testnet/keystore
617572611c98e60ea5fb1dfd0f72996afd2e35294ac4f33dfd4937489c43c65222e06347
6772616ea77e7345133bd15486b7745bade1eed84d8bde1abfc5ea7199411a1fc865786e

$ ls //tmp/node02/chains/local_testnet/keystore
61757261540f2298562a57b3348968793b2e6a5d623232a7d353356d621456f49ebe8902
6772616ea8b2e3955493c2d2608ce6013da726b15982710f1b045fff97e07fe0e3f753b4
  1. Re-run the node. Thats it.
