Tech: [blockchain-object] : TransactionType - CreateBlockchainObject

[andy-shi88]

Description

Create a transaction type to create blockchain object. This transaction type should have the following body fields:

- BlockchainObjectBalance - int64
- BlockchainObjectImmutableProperty: [
      key: string,
      value: string,
  ]

There will be 2 additional table to manage blockchain object:

• blockchain_object

no	field	db_type
1	id	[]byte
2	owner	[]byte
3	height	uint32

• blockchain_object_property [immutable-property of blockchain object]

no	field	db_type
1	blockchain_object_id	[]byte
2	key	string
3	value	string
4	height	uint32

Behaviour

• ApplyUnconfirmed

  • Deduct tx.fee + blockchain_object_balance from sender spendable balance (even if the sender is blockchain object too)

• UndoApplyUnconfirmed

  • refund the cut balance

• ApplyConfirmed

  • Deduct tx.fee + blockchain_object_balance from sender balance (even if the sender is blockchain object too)
  • generate new blockchain_object_id which is [4byte_blockchain_object_accountType][32bytes_tx_hash]
  • insert blockchainObject { owner: tx.Sender, id: blockchain_object_id } to blockchain_object table.
  • insert new row in account_balance table, where the address is blockchain_object_id
  • insert every blockchain object's property to blockchain_object_property table.

Breakdown

• update migration
• create bo transaction type.
