Tutorials about start a private substrate network, Where the suri come from?

Question

The tutorials about start a private substrate network. It says:

This example uses the secret seed generated from the key subcommand into the keystore. In this tutorial, the secret seed generated was 0x563d22ef5f00e589e07445a3ad88bb92efaa897d7f73a4543d9ac87476434e65, so the --suri command-line option specifies that string to insert the key into the keystore:

My wondering is where the suri come from? the article doesn't demo very clearly.

I log what I did:

After import key to keystore

$ ls /tmp/node01/chains/local_testnet/keystore

I restart node1,node2, but The result is :

Idle (1 peers), best: #94 (0x8634…b5c9), finalized #0 (0x4f9a…68f0), ⬇ 40 B/s ⬆ 0.1kiB/s   

finalized block number is always 0

I tried the old version of the topic start a private network, it use the subkey to generate the keys. It worked. but I failed when reference the new tutorial.

Where am I wrong？

Answer 1

Let me to post a correct answer:

$./target/release/node-template key insert --base-path /tmp/node01 \
--chain customSpecRaw.json \
--scheme ed25519 \
--suri 0xa80c9a2c2c96ac61a548a358c81aa07a519af00e7b3fc25f06761e2a5af42044 \
--password-interactive \
--key-type gran

when import grandpa key, add this: --scheme ed25519 .

after do this, It works.

Idle (1 peers), best: #95 (0xf51f…65a8), finalized #93 (0x072b…192a), ⬇ 0.5kiB/s ⬆ 0.6kiB/s
