The genesis transactions are opaque with poor readability

[yangby-cryptape]

What happened

At present, the genesis transactions are generated from previous genesis transactions.

axon/devtools/genesis-generator/src/main.rs

Lines 42 to 53 in 283195b

	for (idx, tx) in genesis.txs.iter_mut().enumerate() {
	let mut utx = tx.transaction.unsigned.clone();
	if idx == 1 {
	utx.set_data(data_0.clone().into());
	} else if idx == 2 {
	utx.set_data(data_1.clone().into())
	}
	let new_tx = build_axon_txs(&priv_key, utx, chain_id);
	*tx = new_tx;
	}

• So, what are the first genesis transactions?

  How to generate the first genesis transactions?

• Since the previous genesis transactions are binary data, how to prove they are safety and trusted, and there are no malicious behaviors in them.

Should the genesis transactions be generated from configurations?

  How to generate the first genesis transactions?

I think we should try to use genesis-generator to generate the first genesis transaction too.
@KaoImin said it is a bit complicated and needs to be carefully designed.

TODO

• Add a document to explain how to use genesis-generator

  	tmp.epoch = metadata_0.epoch + 1;
  	tmp.version.start = metadata_0.version.end + 1;
  	tmp.version.end = tmp.version.start + metadata_0.version.end - 1;

  	let nonce = index as u64;
  	let action = TransactionAction::Call(METADATA_CONTRACT_ADDRESS);
  	let utx = build_unverified_transaction(nonce, action, data);
  	build_transaction(&genesis_key, utx, chain_id)
  	})
  	.collect();
  	let header = self.genesis.build_header();
  	let tx_hashes = txs.iter().map(|tx| tx.transaction.hash).collect::<Vec<_>>();
  	let block = Block { header, tx_hashes };
  	RichBlock { block, txs }
  	}
  	}

• In the test workflows, generate the genesis transactions from readable configurations and double check them against the genesis_xxx.json file

  In this way, the genesis-generator will be well tested too.
