Concepts of Smart Contracts in blockchain

Blockchain use case — Trade Execution and Capture

  1. Client place order (buy/sell a security) to broker (trade execution)
  2. Broker records detail of client’s orders within order management system (manually or electronics)
  3. Order details are forwarded to Trader
  4. Trader enters the trade into the front office system. (trade capture), update trading position Trader decides whether to execute the trade on such terms (Order price is within market’s publish price etc.) Executed trade is handed over to the back office, then recorded to trading book without delay
  1. Broker records the detail of execution
  2. Broker contacts the client to advise whether the order is executed or not. Trade confirmation will be required to issued

Business’s problem

  • In some front office trade capture system, trade details are recorded manually by traders 🡪 trader will need maintain their trading position manually, keeping it updated with any trade 🡪Potential incorrectly recorded trade
  • Trade details required being sent to the back office immediately, without delay
  • The systems involved in capturing these trade details and client account information could easily be enhanced using blockchain technology

  5. Executed Trade is handed over to the BackOffice, conducted validation and recorded to the trading book.
