I am trying to start my own development cluster and would like to stake additional nodes during genesis. I need to use the flag --primordial-accounts-file <FILENAME> but need to know the proper syntax to separate the identity account and balance of the accounts I need to add.

Is there a more in-depth help file description besides solana-genesis --primordial-accounts-file <FILENAME> --help? The location of pubkey for primordial accounts and balance

I can get my bootstrap validator to start voting and slots are confirming but I can't get the bootstrap validator to process transactions (like transfer or airdrop) the signature is shown but never finalized.

I am hoping that is I can get my second remote node staked in genesis it will allow the cluster to process transactions.

  • Thanks @Jon C, do you know what the executable and data fields are for?

  • I had gotten this far from trial and error: val_accounts: owner: "<stake acct pubkey>" balance: 500000000 withdrawer: "<withdraw auth pubkey>" But it was throwing an error wanting data Can you help me decipher that a bit more? Withdrawer must be wrong...and what would executable mean in this context?

  • @jon-c would you know why a local cluster would process slots but not finalize transactions? I can see the slots moving and have a remote node syncing the chain as well. I can initiate airdrop or transfer but it shows me the signature and never finalizes the tx...

    Please comment on my answer next time, since I don't get notifications here! "Executable" is whether the account is a program, and "data" is the data in the account, in base-64. If it's a stake account, you'll need to encode the stake account information as base-64. You can get some example account data by running solana account --output json <ACCOUNT_ADDRESS>

It's unfortunately undocumented, but looking at the code, you need to create a Hashmap<Pubkey, Base64Account>, where account data is a base-64 encoded string, and then dump it to yaml, ie:

        let mut genesis_accounts = HashMap::new();
        genesis_accounts.insert(
            solana_sdk::pubkey::new_rand().to_string(),
            Base64Account {
                owner: solana_sdk::pubkey::new_rand().to_string(),
                balance: 2,
                executable: false,
                data: String::from("aGVsbG8="),
            },
        );
        genesis_accounts.insert(
            solana_sdk::pubkey::new_rand().to_string(),
            Base64Account {
                owner: solana_sdk::pubkey::new_rand().to_string(),
                balance: 1,
                executable: true,
                data: String::from("aGVsbG8gd29ybGQ="),
            },
        );
        genesis_accounts.insert(
            solana_sdk::pubkey::new_rand().to_string(),
            Base64Account {
                owner: solana_sdk::pubkey::new_rand().to_string(),
                balance: 3,
                executable: true,
                data: String::from("bWUgaGVsbG8gdG8gd29ybGQ="),
            },
        );

        let serialized = serde_yaml::to_string(&genesis_accounts).unwrap();
        let path = Path::new("test_append_primordial_accounts_to_genesis.yml");
        let mut file = File::create(path).unwrap();
        file.write_all(b"---\n").unwrap();
        file.write_all(&serialized.into_bytes()).unwrap();

This was lovingly copied from one of the solana-genesis tests https://github.com/solana-labs/solana/blob/cc6c4540766d595a3720e39346b4500f2e2d982c/genesis/src/main.rs#L713
