  數字經濟是以資料資源為關鍵要素,以數字科技為支撐的經濟形態。數字產業化和產業數字化是數字經濟中的重點內容,數字產業化主要是推動數字科技形成規模化產業,產業數字化主要是利用數字科技支撐和推動傳統產業轉型升級。在這個過程中可以基於區塊鏈等數字科技推動資訊科技服務加速數字產業化,依託元宇宙的新場景拉動資訊消費促進產業數字化。


  In the era of Web 3.0,sensors are involved in the detection and identification of planting,transportation,processing and sales.Based on the recognized premise that sensor detection data is true and reliable,artificial intelligence judgment is made through the data collected by sensors in each link(i.e.evidence data),and the performance is performed by smart contracts.


  struct block_header{


  uint32_t timestamp;


  name producer;


  uint16_t confirmed=0;


  capi_checksum256 previous;


  capi_checksum256 transaction_mroot;


  capi_checksum256 action_mroot;


  uint32_t schedule_version=0;


  std::optional<eosio::producer_schedule>new_producers;


  EOSLIB_SERIALIZE(block_header,(timestamp)(producer)(confirmed)(previous)(transaction_mroot)(action_mroot)


  (schedule_version)(new_producers))


  };


  struct wait_weight{


  uint32_t wait_sec;


  uint16_t weight;


  EOSLIB_SERIALIZE(wait_weight,(wait_sec)(weight))


  };需求及模式詳細:StPv888


  該結構體沒有什麼特別的,陌生的部分仍舊只有第一個引數wait_sec,但透過字面含義即可理解,就是等待的秒數。


  struct authority{


  uint32_t threshold=0;


  std::vector<key_weight>keys;


  std::vector<permission_level_weight>accounts;


  std::vector<wait_weight>waits;


  EOSLIB_SERIALIZE(authority,(threshold)(keys)(accounts)(waits))


  };


  #web3環境變數


  export WEB3_INFURA_PROJECT_ID=獲取到的專案ID


  使用該web3.auto.infura模組連線到Infura節點。


  (base)appledeMac-mini-3:Quantification apple$python


  Python 3.7.3(default,Mar 27 2019,16:54:48)


  [Clang 4.0.1(tags/RELEASE_401/final)]::Anaconda,Inc.on darwin


  Type"help","copyright","credits"or"license"for more information.


  >>>from web3.auto.infura import w3


  >>>w3.eth.blockNumber


  將要執行的許多典型操作都在w3.ethAPI中,web3物件通常透過連線到JSON-RPC伺服器來提供與以太坊區塊鏈進行互動的API。
