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

      Network ID:        substrate
      Secret seed:       0x070c94ef16c1a629ddf6b9d1416fa2665e7d5f01bd2113e61a78c53f6e5cda87

      SS58 Address:      5FHANk2EkM6sTeGnkZ2HaRCj356NVWg4DSJag4gsz6Jupazt

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

3. Create Aura-02:

    Secret phrase:       praise scout author learn bounce funny pulp caution young collect whip limb
      Network ID:        substrate
      Secret seed:       0x16df58dcb530ece94270a6154c7d8ad1b3d4aebe69ce55ed2cfe620f6e357a1d

      SS58 Address:      5CZeeFRsRSUweVkqZR3hDTN9khk3U3oa4rjaFg2S96WPpRhd

4. 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

      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.

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

Steps in configuring local_testnet (private network)

1. Create bootnode keys:

# botnode aura
$ subkey generate --scheme sr25519
Secret phrase:       tackle memory pepper lake seed afford since state power label brick copy
  Network ID:        substrate
  Secret seed:       0x81d794359885bb885c357dbf1bf75aff0f6744d532340d9418557ee43c8642ee

  Public key (hex):  0x468d07453610d714e22a33c03b3004dc3b8efb146ec1f2200ae8d68102f0ffe7

  SS58 Address:      5DfD6wftdWs3VqsajyEZMZjsBLk9jTZV5PfihZ3GFCe8YCu7

2. Create node2 keys:

# node2 aura
$ subkey generate --scheme sr25519
Secret phrase:       clump distance vast head photo mass run mosquito chicken wash tattoo escape
  Network ID:        substrate
  Secret seed:       0xca425677c85da882ecec057b47af3ab282253b9d27ed35f9835bc2b794c3d348

  Public key (SS58): 5GsYff9q6wdjt2hXcWyt6W9K7mctwDWpT8QJguMj2svuvnU9
  SS58 Address:      5GsYff9q6wdjt2hXcWyt6W9K7mctwDWpT8QJguMj2svuvnU9

# node2 gran
$ subkey inspect --scheme ed25519 "clump distance vast head photo mass run mosquito chicken wash tattoo escape"
Secret phrase:       clump distance vast head photo mass run mosquito chicken wash tattoo escape
  Network ID:        substrate
  Secret seed:       0xca425677c85da882ecec057b47af3ab282253b9d27ed35f9835bc2b794c3d348

  Public key (SS58): 5FqMQ2bbE3uFmrbiAz4J3Cr3QdEq8NL48BgkVQZYbxFhnf5k
  SS58 Address:      5FqMQ2bbE3uFmrbiAz4J3Cr3QdEq8NL48BgkVQZYbxFhnf5k

3. Authorized the aura and gran addresses for both nodes in the CustomSpec.json file.

#...
      "aura": {
        "authorities": [
          "5DG73DMGcRCdJD55tnMuzAfb9MkwKsgpW5ft7DBpnUxpW3Wg",
          "5GsYff9q6wdjt2hXcWyt6W9K7mctwDWpT8QJguMj2svuvnU9"
        ]
      },
      "grandpa": {
        "authorities": [
          [
            "5DfD6wftdWs3VqsajyEZMZjsBLk9jTZV5PfihZ3GFCe8YCu7",
            1
          ],
          [
            "5FqMQ2bbE3uFmrbiAz4J3Cr3QdEq8NL48BgkVQZYbxFhnf5k",
            1
          ]
        ]
      },
      "balances": {
        "balances": [
          [
            "5DG73DMGcRCdJD55tnMuzAfb9MkwKsgpW5ft7DBpnUxpW3Wg",
            100000000000000000000000
          ]
        ]
      },
      "transactionPayment": null,
      "sudo": {
        "key": "5DG73DMGcRCdJD55tnMuzAfb9MkwKsgpW5ft7DBpnUxpW3Wg"
      }
#...

4. 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

4. 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 \

5. 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

6. Now run the two nodes i different terminal.

$ ./run-bootnode.sh

$ ./run-node2.sh

7. Register the keys of the bootnode.

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

9. Check the keystore for each node

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

$ ls //tmp/node02/chains/local_testnet/keystore
61757261540f2298562a57b3348968793b2e6a5d623232a7d353356d621456f49ebe8902
6772616ea8b2e3955493c2d2608ce6013da726b15982710f1b045fff97e07fe0e3f753b4

9. Re-run the node. Thats it.

Answer 2

I found the problem is substrate. Substrate version v9.20 has problem, so can not peer-id or product block or finalize block.

After I upgrade to v9.24, this issuse was gone.

Answer 3

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

Answer 4

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.
