  // 1) Generate a keypair
  // 2) Airdrop lamports to the account
  // 3) Modify the `solana-validator-info` tool
  //   a) Remove the keybase id verification step
  //   b) Print base64 account data in the `get --all` codepath
  //   c) Add `println!("Account data: {:?}", base64::encode(&account.data));`
  // 4) Use modified `solana-validator-info` tool to publish validator info
  // 5) And then use it again to fetch the data! (feel free to trim some A's)
