此處，首先對後文將要使用的若干概念進行解釋。執行方
：是指司法實踐中，負責對被執行人（法人或個人）進行財產執行的機構或機構的工作人員。例如，執行方可以是法院、法院執行局、法院執行局的執行法官等。被執行使用者
：即依法負有債務的個人或法人。申請執行使用者
：即依法對被執行使用者擁有債權的個人或法人，其可以向執行方申請，對被執行使用者進行財產執行。執行金額
：被執行使用者對申請執行使用者所負債務的金額，也就是執行方針對被執行使用者所要收繳的金額。鎖定金額
：使用者的財產帳戶中，使用者無權處分的部分或全部金額，就是使用者的財產帳戶的鎖定金額。當使用者的財產帳戶有不止一個時，使用者的各財產帳戶分別對應的帳戶類型也是不同的。例如，使用者張三有3個財產帳戶，分別為儲蓄帳戶、養老金帳戶與公積金帳戶。
此外，當使用者的財產帳戶有不止一個時，每個財產帳戶都可以有相應的鎖定子金額，每個財產帳戶的鎖定子金額可以不同，各財產帳戶的鎖定子金額之和是所述使用者無權處分的鎖定金額。也就是說，所述鎖定金額由使用者的每個財產帳戶的鎖定子金額進行分擔。例如，使用者張三無權處分的鎖定金額為10萬元，那麼，使用者張三的儲蓄帳戶的鎖定子金額可以是5萬，養老金帳戶的鎖定子金額可以是3萬，公積金帳戶的鎖定子金額可以是2萬。分攤金額
：若被執行使用者的財產帳戶有不止一個，當執行方針對被執行使用者進行財產執行時，針對被執行使用者的任一財產帳戶，從該財產帳戶中扣除的金額就是該財產帳戶對應的分攤數額。也就是說，執行金額由使用者的全部或部分財產帳戶進行分攤。
為了使本領域技術人員更好地理解本說明書實施例中的技術方案，下面將結合本說明書實施例中的圖式，對本說明書實施例中的技術方案進行詳細地描述，顯然，所描述的實施例僅僅是本說明書的一部分實施例，而不是全部的實施例。基於本說明書中的實施例，本領域普通技術人員所獲得的所有其他實施例，都應當屬於保護的範圍。
以下結合圖式，詳細說明本說明書各實施例提供的技術方案。
圖1是本說明書實施例提供的一種基於區塊鏈的財產執行方法的流程示意圖，包括以下步驟：
S100：執行方設備獲取執行金額與被執行使用者標識。
在本說明書實施例中，針對每個使用者，該使用者的財產帳戶的部分或全部金額被設置為所述被執行使用者無權處分的鎖定金額。其中，使用者無權處分鎖定金額，意味著使用者無法對鎖定金額執行提現、轉帳或其他任何處分操作。
例如，對於個人使用者張三，張三的財產帳戶的餘額為10萬，可以將張三的財產帳戶中的3萬設置為張三無權處分的鎖定金額。又如，對於法人使用者A公司，A公司的財產帳戶的餘額為100萬，可以將A公司的財產帳戶中的20萬設置為A公司無權處分的鎖定金額。
這樣一來，針對任一使用者，當該使用者依法對他人負有債務卻拒絕償還時，執行方可以基於該使用者財產帳戶的鎖定金額，對該使用者進行財產執行。
在本說明書實施例中，針對每個使用者，該使用者的財產帳戶的鎖定金額通過如下方式判定：
獲取該使用者對應的信用評分；該使用者對應的信用評分與對該使用者的信用評價正相關；根據該使用者的財產帳戶的餘額與該使用者對應的信用評分，判定該使用者的財產帳戶的鎖定金額；該使用者的財產帳戶的鎖定金額與該使用者的財產帳戶的餘額正相關，該使用者的財產帳戶的鎖定金額與該使用者對應的信用評分負相關。
其中，在實際應用中，使用者對應的信用評分，可以是某個負責執行信用評價業務的區塊鏈網路給出的。
在本說明書實施例中，執行方設備具體可以是執行方的伺服器、電腦、手機等設備。需要說明的是，在實際應用中，在司法領域可以建構用於執行司法相關業務的區塊鏈網路（可稱為司法區塊鏈網路），所述司法區塊鏈網路中的節點可以是各級法院、警察機關以及檢察院的設備。這種情況下，所述執行方設備可以是司法區塊鏈網路中的一個節點。
在步驟S100中，執行方設備可以接收執行方輸入的執行金額與被執行使用者標識。
S102：所述執行方設備將所述執行金額與所述被執行使用者標識發送給區塊鏈網路。
S104：所述區塊鏈網路中的各節點基於共識機制，將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈。
步驟S102中的區塊鏈網路，可以是負責管理使用者的財產帳戶的區塊鏈網路。例如，所述區塊鏈網路可以是由各大銀行組成的聯盟鏈網路，該聯盟鏈網路中的一個節點是一個銀行的設備。
在步驟S102~S104中，執行方設備可以將所述執行金額與所述被執行使用者標識發送給所述區塊鏈網路，然後，所述區塊鏈網路中的各節點會基於共識機制，將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈進行存證。
需要說明的是，在本說明書中所描述的交易（transaction），是指使用者通過區塊鏈的使用者端創建，並需要最終發佈至區塊鏈的分散式資料庫中的一筆資料。
也就是說，區塊鏈中的交易，存在狹義的交易以及廣義的交易之分。狹義的交易是指使用者向區塊鏈發佈的一筆價值轉移；例如，在傳統的比特幣區塊鏈網路中，交易可以是使用者在區塊鏈中發起的一筆轉帳。而廣義的交易是指使用者向區塊鏈發佈的一筆具有業務意圖的業務資料；例如，運營方可以基於實際的業務需求搭建一個聯盟鏈，依託於聯盟鏈部署一些與價值轉移無關的其它類型的線上業務（比如，租房業務、車輛調度業務、保險理賠業務、信用服務、醫療服務等），而在這類聯盟鏈中，交易可以是使用者在聯盟鏈中發佈的一筆具有業務意圖的業務消息或者業務請求。
基於此，存在兩種情況：
1、在步驟S102中，所述執行方設備可以將包含所述執行金額與所述被執行使用者標識的執行指令發送給所述區塊鏈網路中的任一節點（本文將之稱為目標節點），所述目標節點可以基於所述執行指令，構建上述的執行交易，並將執行交易廣播至所述區塊鏈網路中的其他節點。
對於情況1，進一步地，在步驟S102中，所述執行方設備使用自身的私鑰對包含所述執行金額與所述被執行使用者標識的執行指令進行簽名，以及，將簽名後的所述執行指令發送給目標節點。相應地，所述目標節點可以使用所述執行方設備的公鑰對所述執行指令進行簽名驗證通過後，基於所述執行指令構建執行交易。
由於在實踐中，財產執行是特定執法機關才有權進行的司法行為，因此，目標節點需要確保向其發送執行指令的設備是執行方的設備。
2、在步驟S102中，所述執行方設備也可以構建包含所述執行金額與所述被執行使用者標識的執行交易，然後將所述執行交易廣播給所述區塊鏈網路中的各節點。
對於情況2，進一步地，在實踐中，如果只有區塊鏈網路中的節點有許可權構建交易，那麼，所述執行方設備一般並沒有許可權構建上述的執行交易。因此，所述執行方設備可以獲取所述區塊鏈網路提供的帳戶管理私鑰，從而擁有在所述區塊鏈網路之外發起交易的許可權。
具體地，在步驟S102中，所述執行方設備使用所述區塊鏈網路提供的帳戶管理私鑰，對包含所述執行金額與所述被執行使用者標識的執行交易進行簽名，並將簽名後的所述執行交易廣播給所述區塊鏈網路中的各節點。相應地，在步驟S104中，所述區塊鏈網路中的各節點在使用所述帳戶管理私鑰對應的帳戶管理公鑰對所述執行交易進行簽名驗證通過後，基於共識機制，將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈。
S106：所述區塊鏈網路中的各節點基於所述執行金額，從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款。
在本說明書實施例中，所述區塊鏈網路中的每個節點上可以預先部署有用於實現財產執行邏輯的智慧合約。如此，在步驟S106中，所述區塊鏈網路中的每個節點可以調用所述智慧合約，對管理的被執行使用者標識對應的財產帳戶進行操作，基於所述執行金額，從被執行使用者標識對應的財產帳戶的鎖定金額中扣款。
具體地，對於所述區塊鏈網路中的每個節點而言，若判定所述執行金額小於所述被執行使用者標識對應的財產帳戶的鎖定金額，則該節點可以從所述被執行使用者標識對應的財產帳戶的鎖定金額中，扣除所述執行金額；若判定所述執行金額不小於所述被執行使用者標識對應的財產帳戶的鎖定金額，則該節點可以從所述被執行使用者標識對應的財產帳戶中，扣除所述被執行使用者標識對應的財產帳戶的鎖定金額。
在本說明書實施例中，所述區塊鏈網路中的各節點在從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款之後，可以將扣款的金額轉交給執行方或申請執行使用者。
進一步地，如果執行方在所述區塊鏈網路中也開通了財產帳戶，那麼，所述區塊鏈網路中的各節點在從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款之後，可以向執行方使用者的財產帳戶中增加扣款的金額。
如果申請執行使用者在所述區塊鏈網路中也開通了財產帳戶，那麼，所述執行交易中還可以包括所述執行方設備獲取的申請執行使用者標識。於是，所述區塊鏈網路中的各節點在從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款之後，向所述申請執行使用者標識對應的財產帳戶中增加扣款的金額。
通過圖1所示的方法，針對每個使用者，將該使用者的財產帳戶的部分或全部金額設置為所述被執行使用者無權處分的鎖定金額。使用者的財產帳戶是由區塊鏈網路負責管理的。當執行方需要針對被執行使用者進行財產執行時，可以直接將需要執行的執行金額以及被執行使用者的使用者標識發送給區塊鏈網路，區塊鏈網路中的各節點在將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈進行存證之後，會基於所述執行金額，從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款。如此，執行方就可以順利實現對被執行使用者的財產執行，解決了財產執行難的問題。並且，執行方的財產執行記錄也會被公示於區塊鏈上，不可消除，不可篡改。
此外，在實際應用中，使用者可以擁有不同帳戶類型的財產帳戶，如儲蓄帳戶、養老金帳戶、公積金帳戶、醫保帳戶等等。
因此，在本說明書實施例中，可以對每個使用者的不同帳戶類型的財產帳戶都設置相應的鎖定金額。需要說明的是，擁有至少兩個不同帳戶類型的財產帳戶的使用者一般是指個人使用者。因為在實踐中，法人使用者的財產帳戶對應的帳戶類型一般是儲蓄類型，而個人使用者可以擁有不同帳戶類型的財產帳戶，如儲蓄帳戶、公積金帳戶、養老金帳戶等。
在本說明書實施例中，以任一使用者為例，針對該使用者的每個財產帳戶，該財產帳戶的部分或全部金額被設置為該使用者無權處分的鎖定子金額，該使用者的各財產帳戶的鎖定子金額之和是該使用者無權處分的鎖定金額。
如此，在步驟S102中，所述執行方設備從被執行使用者的各財產帳戶中選擇至少一個財產帳戶，作為目標財產帳戶，並根據所述執行金額，判定每個目標財產帳戶對應的分攤金額。然後，所述執行方設備針對每個目標財產帳戶，將所述被執行使用者標識與該目標財產帳戶對應的分攤金額發送給區塊鏈網路。
其中，各目標財產帳戶分別對應的分攤金額之和是所述執行金額。還需要說明的是，在本說明書實施例中，負責管理各帳戶類型的財產帳戶的區塊鏈網路可以是同一個區塊鏈網路，也可以不是同一個區塊鏈網路。
基於此，在步驟S104~S106中，所述區塊鏈網路中的各節點可以針對每個目標財產帳戶，基於共識機制，將包含所述被執行使用者標識與該目標財產帳戶對應的分攤金額的執行子交易發佈至區塊鏈；進而從該目標財產帳戶的鎖定子金額中扣除該目標財產帳戶對應的分攤金額。
進一步地，該使用者的各財產帳戶的鎖定子金額可以通過如下方式判定：
首先，對該使用者的各財產帳戶進行排序。
其次，根據該使用者無權處分的鎖定金額，選擇前N個財產帳戶。其中，N不大於M，前N個財產帳戶的餘額之和不小於該使用者無權處分的鎖定金額，前N-1個財產帳戶的餘額之和小於該使用者無權處分的鎖定金額；M為該使用者的財產帳戶的數量。
然後，針對前N-1個財產帳戶中的每個財產帳戶，將該財產帳戶的餘額判定為該財產帳戶的鎖定子金額；並且，將該使用者無權處分的鎖定金額減去前N-1個財產帳戶的餘額之和的差，判定為第N個財產帳戶的鎖定子金額；並且，若N小於M，則還將未選擇的M-N個財產帳戶的鎖定子金額判定為0。
需要說明的是，上述的對使用者的各財產帳戶進行排序的規則可以根據實際需要指定。
舉例來說，假設使用者張三有儲蓄帳戶（餘額為100萬）、養老金帳戶（餘額為20萬）和公積金帳戶（餘額為50萬）。根據生活常識，使用者可以隨意提取儲蓄帳戶中的金額，而使用者通常需要滿足一定的條件（如退休後或要買房）後，才能提取養老金帳戶與公積金帳戶中的金額。基於此，如果張三的信用較好，可以考慮在對張三的財產進行鎖定時，優先鎖定張三的養老金帳戶與公積金帳戶中的金額。於是，可以將張三的3個財產帳戶由前到後排序為養老金帳戶-公積金帳戶-儲蓄帳戶。假設張三無權處分的鎖定金額為80萬，那麼，可以將張三的養老金帳戶與公積金帳戶的餘額全部作為鎖定子金額，將張三的儲蓄帳戶中的10萬作為鎖定子金額。
當然，如果張三的信用較差，也可以考慮在對張三的財產進行鎖定時，優先鎖定張三的儲蓄帳戶中的金額，直至張三的儲蓄帳戶的餘額全部被設置為鎖定子金額。
當針對被執行使用者進行財產執行時，首先需要從被執行使用者的各財產帳戶中選擇要徵用的財產帳戶，作為目標財產帳戶。此外，還要根據執行金額，判定每個目標財產帳戶所要分攤的金額。本領域技術人員很容易想到多種判定目標財產帳戶的方式（例如隨機選擇），和判定每個目標財產帳戶對應的分攤金額的方式。總之，針對每個目標財產帳戶，該目標財產帳戶對應的分攤金額不大於該目標財產帳戶的鎖定金額，並且，各目標財產帳戶分別對應的分攤金額之和為所述執行金額。
進一步地，可以根據上述各財產帳戶的排列順序判定目標財產帳戶。具體地，所述執行方設備選擇前S個財產帳戶，作為目標財產帳戶。其中，S不大於M；前S個財產帳戶的鎖定子金額之和不小於所述執行金額，前S-1個財產帳戶的鎖定子金額之和小於所述執行金額。
如此，沿用上例，張三的財產帳戶的排列順序是養老金帳戶-公積金帳戶-儲蓄帳戶，那麼，對張三的財產的執行順序也是養老金帳戶-公積金帳戶-儲蓄帳戶。當前的財產帳戶的鎖定子金額用盡後，才會針對下一個財產帳戶的鎖定子金額進行執行。假設執行方需要針對張三收繳50萬（執行金額為50萬），那麼，由於張三的養老金帳戶和公積金帳戶的鎖定子金額之和已經足夠支付所述執行金額了，因此，可以將張三的養老金帳戶和公積金帳戶判定為目標財產帳戶，不需要將張三的儲蓄帳戶判定為目標財產帳戶。
此外，判定每個目標財產帳戶對應的分攤金額的方式可以是：
針對前S-1個目標財產帳戶中的每個目標財產帳戶，將該目標財產帳戶的鎖定子金額判定為該目標財產帳戶對應的分攤金額；並且，將所述執行金額減去前S-1個目標財產帳戶的鎖定子金額之和的差，判定為第S個財產帳戶對應的分攤金額。
還是沿用上例，由於張三的養老金帳戶與公積金帳戶為目標財產帳戶，首先，針對張三的養老金帳戶，將相應的鎖定子金額20萬判定為養老金帳戶對應的分攤金額，然後，針對張三的公積金帳戶，將相應的鎖定子金額50萬中的30萬判定為公積金帳戶對應的分攤金額。
圖2是本說明書實施例提供的基於區塊鏈的財產執行系統的結構示意圖，圖2所示的系統包括：執行方設備與區塊鏈網路，所述區塊鏈網路負責管理使用者的財產帳戶；
所述執行方設備，獲取執行金額與被執行使用者標識；將所述執行金額與所述被執行使用者標識發送給區塊鏈網路；
所述區塊鏈網路中的各節點，基於共識機制，將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈；進而基於所述執行金額，從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款。
在圖2中，存在兩個區塊鏈網路，分別為司法區塊鏈網路、負責管理使用者的財產帳戶的區塊鏈網路（可以由各銀行組成）。每個使用者通常只擁有一個帳戶類型的財產帳戶。
其中，司法區塊鏈網路中的任一節點作為所述執行方設備，發起對被執行使用者的財產執行。所述執行方設備首先獲取執行金額和被執行使用者標識，然後將執行金額和被執行使用者標識發送給區塊鏈網路進行財產執行即可。
圖3是本說明書實施例提供的另一種基於區塊鏈的財產執行系統的結構示意圖。在圖3中，存在4個區塊鏈網路，分別為司法區塊鏈網路、負責管理儲蓄帳戶的區塊鏈網路（可以由各銀行組成）、負責管理養老金帳戶的區塊鏈網路（可以由各地養老金管理機構組成）、負責管理公積金帳戶（可以由各地公積金管理機構組成）的區塊鏈網路。其中，司法區塊鏈網路中的任一節點作為所述執行方設備，發起對被執行使用者的財產執行。所述執行方設備首先獲取執行金額和被執行使用者標識，然後根據執行金額與被執行使用者的每個財產帳戶的鎖定子金額，選擇被執行使用者的至少一個財產帳戶作為目標財產帳戶（依次選擇養老金帳戶、公積金帳戶作為目標財產帳戶），並判定每個目標財產帳戶對應的分攤金額。接著，執行方設備就可以分別針對每個目標財產帳戶對應區塊鏈網路進行財產執行。
基於圖1所示的基於區塊鏈的財產執行裝置，本說明書實施例還對應提供了一種基於區塊鏈的財產執行裝置，如圖4所示，針對每個使用者，該使用者的財產帳戶的部分或全部金額被設置為所述被執行使用者無權處分的鎖定金額，所述裝置包括：
獲取模組401，獲取執行金額與被執行使用者標識；
發送模組402，將所述執行金額與所述被執行使用者標識發送給區塊鏈網路；所述區塊鏈網路負責管理使用者的財產帳戶，以使所述區塊鏈網路中的各節點基於共識機制，將包含所述執行金額與所述被執行使用者標識的執行交易發佈至區塊鏈，並基於所述執行金額，從所述被執行使用者標識對應的財產帳戶的鎖定金額中扣款。

處理器1010可以採用通用的CPU（Central Processing Unit，中央處理器）、微處理器、特殊應用積體電路（Application Specific Integrated Circuit，ASIC）、或者一個或多個積體電路等方式實現，用於執行相關程式，以實現本說明書實施例所提供的技術方案。
記憶體1020可以採用ROM（Read Only Memory，唯讀記憶體）、RAM（Random Access Memory，隨機存取記憶體）、靜態存放裝置，動態儲存裝置設備等形式實現。記憶體1020可以儲存作業系統和其他應用程式，在通過軟體或者韌體來實現本說明書實施例所提供的技術方案時，相關的程式碼保存在記憶體1020中，並由處理器1010來調用執行。
輸入/輸出介面1030用於連接輸入/輸出模組，以實現資訊輸入及輸出。輸入輸出/模組可以作為元件配置在設備中（圖中未示出），也可以外接於設備以提供相應功能。其中輸入裝置可以包括鍵盤、滑鼠、觸控式螢幕、麥克風、各類感測器等，輸出設備可以包括顯示器、揚聲器、振動器、指示燈等。
通信介面1040用於連接通信模組（圖中未示出），以實現本設備與其他設備的通信交互。其中通信模組可以通過有線方式（例如USB、網線等）實現通信，也可以通過無線方式（例如行動網路、WIFI、藍牙等）實現通信。
匯流排1050包括一通路，在設備的各個元件（例如處理器1010、記憶體1020、輸入/輸出介面1030和通信介面1040）之間傳輸資訊。
需要說明的是，儘管上述設備僅示出了處理器1010、記憶體1020、輸入/輸出介面1030、通信介面1040以及匯流排1050，但是在具體實施過程中，該設備還可以包括實現正常運行所必需的其他元件。此外，本領域的技術人員可以理解的是，上述設備中也可以僅包含實現本說明書實施例方案所必需的組件，而不必包含圖中所示的全部元件。

以上所述僅是本說明書實施例的具體實施方式，應當指出，對於本技術領域的普通技術人員來說，在不脫離本說明書實施例原理的前提下，還可以做出若干改進和潤飾，這些改進和潤飾也應視為本說明書實施例的保護範圍。Here, first explain some concepts that will be used later. Executor : Refers to the agency or staff of the agency responsible for the execution of the property of the person subject to execution (legal person or individual) in judicial practice. For example, the enforcement party can be an enforcement judge of a court, a court enforcement bureau, or a court enforcement bureau. Enforced user : an individual or legal person who has debts in accordance with the law. Application for enforcement user : that is, an individual or legal person who has a creditor's right to the enforced user in accordance with the law, and it can apply to the enforcement party to perform property enforcement on the enforced user. Execution amount : The amount of debt the executed user owes to the user applying for execution, that is, the amount that the execution party needs to collect for the executed user. Locked amount : In the user's property account, part or all of the amount that the user has no right to dispose of is the locked amount of the user's property account. When the user has more than one property account, the account types corresponding to each property account of the user are also different. For example, the user Zhang San has 3 property accounts, namely a savings account, a pension account and a provident fund account. In addition, when the user has more than one property account, each property account can have a corresponding locked sub-amount, and the locked sub-amount of each property account can be different. The sum of the locked sub-amount of each property account is the stated use The locked-up amount that the person has no right to dispose. That is, the locked amount is shared by the locked sub-amount of each property account of the user. For example, if user Zhang San has no right to dispose of the locked amount of 100,000 yuan, then the locked sub-amount of user Zhang San’s savings account can be 50,000, the locked-up sub-amount of pension account can be 30,000, and that of provident fund account The locked sub-amount can be 20,000. Apportionment amount : If there is more than one property account of the executed user, when the executing party performs property execution against the executed user, for any property account of the executed user, the amount deducted from the property account is the property The allocation amount corresponding to the account. In other words, the execution amount is apportioned by all or part of the user's property account. In order to enable those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation The examples are only a part of the embodiments of this specification, not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by a person of ordinary skill in the art should fall within the scope of protection. The following describes in detail the technical solutions provided by the embodiments of this specification in conjunction with the drawings. Fig. 1 is a schematic flowchart of a blockchain-based property execution method provided by an embodiment of the specification, including the following steps: S100: the executing party device obtains the executed amount and the executed user identifier. In the embodiment of this specification, for each user, part or all of the amount of the user's property account is set as the locked amount that the executed user has no right to dispose. Among them, the user has no right to dispose of the locked amount, which means that the user cannot perform withdrawal, transfer or any other disciplinary operations on the locked amount. For example, for individual user Zhang San, the balance of Zhang San’s property account is 100,000, and 30,000 in Zhang San’s property account can be set as the locked amount that Zhang San has no right to dispose of. In another example, for the legal person company A, the balance of the property account of the company A is 1 million, and the 200,000 in the property account of the company A can be set as the lock-up amount that the company A has no right to dispose of. In this way, for any user, when the user owes debts to others in accordance with the law but refuses to repay, the enforcement party can perform property enforcement for the user based on the locked amount of the user's property account. In the embodiment of this specification, for each user, the locked amount of the user’s property account is determined as follows: obtain the user’s credit score; the user’s corresponding credit score and the user’s credit Evaluation is positively correlated; according to the user’s property account balance and the user’s corresponding credit score, determine the locked amount of the user’s property account; the locked amount of the user’s property account and the user’s property account The balance is positively correlated, and the locked amount of the user’s property account is negatively correlated with the user’s corresponding credit score. Among them, in practical applications, the user's corresponding credit score may be given by a blockchain network responsible for performing credit evaluation services. In the embodiments of this specification, the executor's device may specifically be a server, computer, mobile phone and other devices of the executor. It should be noted that in practical applications, a blockchain network (which can be called a judicial blockchain network) for the execution of judicial-related businesses can be constructed in the judicial field, and the nodes in the judicial blockchain network It can be equipment of courts, police agencies and procuratorates at all levels. In this case, the executor's device may be a node in the judicial blockchain network. In step S100, the executor device may receive the execution amount input by the executor and the executed user identification. S102: The executor device sends the executed amount and the executed user identifier to the blockchain network. S104: Based on the consensus mechanism, each node in the blockchain network publishes the execution transaction including the execution amount and the executed user identifier to the blockchain. The blockchain network in step S102 may be a blockchain network responsible for managing the user's property account. For example, the blockchain network may be a consortium chain network composed of major banks, and a node in the consortium chain network is a bank's equipment. In steps S102 to S104, the executor device may send the executed amount and the executed user identifier to the blockchain network, and then, each node in the blockchain network will be based on consensus Mechanism to publish the execution transaction including the execution amount and the executed user identifier to the blockchain for deposit. It should be noted that the transaction described in this manual refers to a piece of data created by the user through the user end of the blockchain and needs to be finally released to the distributed database of the blockchain. In other words, transactions in the blockchain are divided into narrow transactions and broad transactions. A transaction in a narrow sense refers to a transfer of value issued by a user to the blockchain; for example, in a traditional Bitcoin blockchain network, a transaction can be a transfer initiated by the user in the blockchain. In a broad sense, a transaction refers to a piece of business data with business intentions released by users to the blockchain; for example, the operator can build a consortium chain based on actual business needs, and rely on the consortium chain to deploy other types that are not related to value transfer Online business (for example, renting business, vehicle dispatching business, insurance claims business, credit service, medical service, etc.), and in this kind of alliance chain, the transaction can be a business with business intent issued by the user in the alliance chain Message or business request. Based on this, there are two situations: 1. In step S102, the executor device may send an execution instruction including the execution amount and the executed user identifier to any person in the blockchain network. A node (herein referred to as a target node), the target node can construct the above-mentioned execution transaction based on the execution instruction, and broadcast the execution transaction to other nodes in the blockchain network. For case 1, further, in step S102, the executor device uses its own private key to sign the execution instruction containing the execution amount and the executed user identifier, and the signed The execution instruction is sent to the target node. Correspondingly, the target node may use the public key of the executor device to perform signature verification on the execution instruction, and then construct an execution transaction based on the execution instruction. In practice, property execution is a judicial act that a specific law enforcement agency has the right to carry out. Therefore, the target node needs to ensure that the device sending the execution instruction to it is the device of the executor. 2. In step S102, the executor device may also construct an execution transaction including the execution amount and the executed user identification, and then broadcast the execution transaction to each of the blockchain network node. For case 2, further, in practice, if only nodes in the blockchain network have permission to construct transactions, then the executor device generally does not have permission to construct the above-mentioned execution transactions. Therefore, the executor device can obtain the account management private key provided by the blockchain network, thereby having the permission to initiate transactions outside the blockchain network. Specifically, in step S102, the executor device uses the account management private key provided by the blockchain network to sign the execution transaction including the execution amount and the executed user identifier, and The executed transaction after the signature is broadcast to each node in the blockchain network. Correspondingly, in step S104, after each node in the blockchain network uses the account management public key corresponding to the account management private key to sign and verify the execution transaction, based on the consensus mechanism, it will include The execution transaction of the execution amount and the executed user identifier is published to the blockchain. S106: Based on the execution amount, each node in the blockchain network deducts money from the locked amount of the property account corresponding to the executed user ID. In the embodiments of this specification, each node in the blockchain network may be pre-deployed with a smart contract for realizing property execution logic. In this way, in step S106, each node in the blockchain network can call the smart contract to operate on the managed property account corresponding to the executed user ID, and based on the executed amount, from the executed The user ID is deducted from the locked amount of the property account. Specifically, for each node in the blockchain network, if it is determined that the execution amount is less than the locked amount of the property account corresponding to the executed user ID, the node can start from the executed The execution amount is deducted from the lock amount of the property account corresponding to the user ID; if it is determined that the execution amount is not less than the lock amount of the property account corresponding to the executed user ID, the node can obtain the amount from the executed From the property account corresponding to the user identification, the locked amount of the property account corresponding to the executed user identification is deducted. In the embodiment of this specification, each node in the blockchain network can transfer the deducted amount to the executor or after deducting from the locked amount of the property account corresponding to the executed user ID Apply for execution user. Further, if the executor also opens a property account in the blockchain network, then each node in the blockchain network will obtain the locked amount of the property account corresponding to the executed user ID After the deduction, the amount of deduction can be added to the property account of the executing party user. If the application execution user has also opened a property account in the blockchain network, the execution transaction may also include the application execution user identification obtained by the execution party device. Therefore, after each node in the blockchain network deducts money from the locked amount of the property account corresponding to the executed user ID, it adds a deduction to the property account corresponding to the user ID applying for execution Amount. Through the method shown in FIG. 1, for each user, part or all of the amount of the user's property account is set as the locked amount that the executed user has no right to dispose. The user's property account is managed by the blockchain network. When the executor needs to execute property execution against the executed user, it can directly send the execution amount to be executed and the user ID of the executed user to the blockchain network, and each node in the blockchain network After the execution transaction including the execution amount and the executed user ID is posted to the blockchain for deposit, based on the execution amount, the locked amount of the property account corresponding to the executed user ID will be deducted paragraph. In this way, the executing party can smoothly implement the execution of the property of the executed user, and solve the problem of difficult property execution. In addition, the property execution records of the executor will also be published on the blockchain, which cannot be eliminated and cannot be tampered with. In addition, in practical applications, users can have property accounts of different account types, such as savings accounts, pension accounts, provident fund accounts, medical insurance accounts, and so on. Therefore, in the embodiment of this specification, a corresponding lock amount can be set for each user's property account of different account types. It should be noted that users who have at least two property accounts of different account types generally refer to individual users. Because in practice, the account type corresponding to the property account of legal person users is generally a savings type, while individual users can have property accounts of different account types, such as savings accounts, provident fund accounts, and pension accounts. In the embodiment of this specification, taking any user as an example, for each property account of the user, part or all of the amount of the property account is set as a locked sub-amount that the user has no right to dispose of. The sum of the locked sub-amount of each property account is the locked amount that the user has no right to dispose. In this way, in step S102, the executor device selects at least one property account from the property accounts of the executed user as the target property account, and determines the apportionment amount corresponding to each target property account based on the execution amount . Then, for each target property account, the executor device sends the executed user identifier and the apportioned amount corresponding to the target property account to the blockchain network. Among them, the sum of the apportioned amounts corresponding to each target property account is the execution amount. It should also be noted that, in the embodiments of this specification, the blockchain network responsible for managing property accounts of various account types may be the same blockchain network, or may not be the same blockchain network. Based on this, in steps S104 to S106, each node in the blockchain network can, for each target property account, based on the consensus mechanism, include the apportionment corresponding to the executed user ID and the target property account The executed sub-transaction of the amount is posted to the blockchain; then the apportioned amount corresponding to the target property account is deducted from the locked sub-amount of the target property account. Further, the locked sub-amount of each property account of the user can be determined in the following manner: First, the property accounts of the user are sorted. Second, select the top N property accounts based on the locked amount that the user has no right to dispose of. Among them, N is not greater than M, the sum of the balances of the first N property accounts is not less than the locked amount that the user has no right to dispose, and the sum of the balances of the first N-1 property accounts is less than the locked amount that the user has no right to dispose of; M is the number of property accounts of the user. Then, for each of the first N-1 property accounts, determine the balance of the property account as the locked sub-amount of the property account; and subtract the previous N- amount from the locked amount that the user has no right to dispose of The difference between the sum of the balances of one property account is determined as the locked sub-amount of the Nth property account; and, if N is less than M, the locked sub-amount of the unselected MN property accounts is also determined as 0. It should be noted that the aforementioned rules for sorting the user's property accounts can be specified according to actual needs. For example, suppose that the user Zhang San has a savings account (with a balance of 1 million), a pension account (with a balance of 200,000), and a provident fund account (with a balance of 500,000). According to common sense of life, users can withdraw the amount in the savings account at will, and users usually need to meet certain conditions (such as after retirement or buying a house) before they can withdraw the amount in the pension account and provident fund account. Based on this, if Zhang San’s credit is good, he can consider locking Zhang San’s pension account and provident fund account with priority when locking Zhang San’s property. Therefore, Zhang San’s three property accounts can be sorted from front to back into pension account-provident fund account-savings account. Assuming that the locked amount that Zhang San has no right to dispose is 800,000, then all the balances of Zhang San's pension account and provident fund account can be used as the locked sub-amount, and 100,000 in Zhang San's savings account can be used as the locked sub-amount. Of course, if Zhang San’s credit is poor, you can also consider locking the amount in Zhang San’s savings account first when locking Zhang San’s property, until the balance of Zhang San’s savings account is all set as a locked sub-amount. When carrying out property execution against the executed user, firstly select the property account to be requisitioned from the property accounts of the executed user as the target property account. In addition, it is necessary to determine the amount to be apportioned for each target property account based on the execution amount. Those skilled in the art can easily think of multiple ways to determine the target property account (for example, random selection) and ways to determine the apportioned amount corresponding to each target property account. In short, for each target property account, the apportioned amount corresponding to the target property account is not greater than the locked amount of the target property account, and the sum of the apportioned amounts corresponding to each target property account is the execution amount. Further, the target property account can be determined according to the sequence of the foregoing property accounts. Specifically, the executor device selects the first S property accounts as the target property accounts. Among them, S is not greater than M; the sum of locked sub-amounts of the first S property accounts is not less than the execution amount, and the sum of the locked sub-amounts of the first S-1 property accounts is less than the execution amount. In this way, following the above example, the order of Zhang San’s property accounts is pension account-provident fund account-savings account, so the execution order of Zhang San's property is also pension account-provident fund account-savings account. After the locked sub-amount of the current property account is exhausted, execution will be executed against the locked sub-amount of the next property account. Assuming that the executor needs to collect 500,000 for Zhang San (the execution amount is 500,000), then, since the sum of the locked sub-amount of Zhang San’s pension account and provident fund account is sufficient to cover the execution amount, Zhang can be transferred Three pension accounts and provident fund accounts are determined as target property accounts, and Zhang San’s savings account does not need to be determined as target property accounts. In addition, the method for determining the apportioned amount corresponding to each target property account may be: For each of the first S-1 target property accounts, determine the locked sub-amount of the target property account as the corresponding target property account And, the difference between the execution amount minus the sum of the locked sub-amounts of the previous S-1 target property accounts is determined as the apportioned amount corresponding to the Sth property account. Still using the above example, since Zhang San’s pension account and provident fund account are the target property accounts, first of all, for Zhang San’s pension account, the corresponding locked sub-amount of 200,000 is determined as the apportionment amount corresponding to the pension account, and then, For Zhang San’s provident fund account, 300,000 of the corresponding locked sub-amount of 500,000 was determined as the apportioned amount corresponding to the provident fund account. Figure 2 is a schematic structural diagram of a blockchain-based asset execution system provided by an embodiment of this specification. The system shown in Figure 2 includes: an executor device and a blockchain network, and the blockchain network is responsible for managing users The property account of the executor; the executor device obtains the execution amount and the executed user identification; sends the execution amount and the executed user identification to the blockchain network; the blockchain network Based on the consensus mechanism, each node publishes the execution transaction including the execution amount and the executed user identification to the blockchain; and then based on the execution amount, from the property account corresponding to the executed user identification Deduction from the locked amount. In Figure 2, there are two blockchain networks, namely the judicial blockchain network and the blockchain network responsible for managing users' property accounts (which can be composed of banks). Each user usually has only one account type of property account. Among them, any node in the judicial blockchain network serves as the executor device to initiate execution of the property of the executed user. The executor device first obtains the execution amount and the executed user identification, and then sends the execution amount and executed user identification to the blockchain network for property execution. Fig. 3 is a schematic structural diagram of another blockchain-based property execution system provided by an embodiment of this specification. In Figure 3, there are 4 blockchain networks, namely the judicial blockchain network, the blockchain network responsible for managing savings accounts (which can be composed of banks), and the blockchain responsible for managing pension accounts. The network (which can be composed of various pension management institutions), a blockchain network responsible for managing provident fund accounts (which can be composed of various local provident fund management institutions). Among them, any node in the judicial blockchain network serves as the executor device to initiate execution of the property of the executed user. The executor device first obtains the execution amount and the executed user identification, and then selects at least one property account of the executed user as the target property account according to the execution amount and the locked sub-amount of each property account of the executed user ( Select the pension account and provident fund account as the target property account in turn, and determine the apportionment amount corresponding to each target property account. Then, the executor's device can execute property execution for each target property account corresponding to the blockchain network. Based on the blockchain-based property execution device shown in Figure 1, the embodiment of this specification also provides a blockchain-based property execution device. As shown in Figure 4, for each user, the user’s property Part or all of the amount of the account is set to the locked amount that the executed user has no right to dispose of. The device includes: an obtaining module 401, which obtains the executed amount and the executed user’s identifier; and a sending module 402, The execution amount and the executed user ID are sent to the blockchain network; the blockchain network is responsible for managing the user’s property account, so that each node in the blockchain network is based on a consensus mechanism, Publish the execution transaction including the execution amount and the executed user identification to the blockchain, and based on the execution amount, deduct from the locked amount of the property account corresponding to the executed user identification.
