Transfer - smart contract¶

“The transfer of asset from one account to another is one operation and a smart contract.”

In this section, we examine how worker proposal smart contract was constructed. There are items and helpful steps to construct a smart contract. We want to list those items by examining BitShares blockchain components.

Smart contract items
- Object
- Object Index and Call
- Operations
- Validations
- Initialize Evaluators and Index
- Evaluators
- API call

Items¶

Object¶

account_object
account_balance_object
asset_object
asset_dynamic_data_object

Object Index and Search Call¶

generic_index
get_asset()
get_account()

Operations¶

transfer_operation
override_transfer_operation
blind_transfer_operation
transfer_from_blind_operation
transfer_to_blind_operation

Validations¶

Initialize Evaluators and Index¶

void database::initialize_evaluators()
{
   _operation_evaluators.resize(255);
   register_evaluator<account_create_evaluator>()
   .......
}

void database::initialize_indexes()
{
   reset_indexes();
   _undo_db.set_max_size( GRAPHENE_MIN_UNDO_HISTORY );

   .....
}


void database::init_genesis(const genesis_state_type& genesis_state)
{ try {
.....

}}
