1. In the e-commerce industry, the 2/3 mode is more common. In the past, the payment industry handled disputes by joining third-party intermediaries such as Alipay and PayPal. The negotiation and communication between all parties inevitably makes the whole processing flow lengthy and inefficient.

When trading with digital currency, funds can be directly transferred between buyers and sellers, which can greatly reduce the number of stakeholders involved in the trading process, reduce costs and improve efficiency.

2. Division of property. For example, if both husband and wife have property, they can use the mode of 1/2, and anyone can use an account. The advantage is that the system truthfully records everyone's expenditure details, and the disputes between husband and wife are easy to solve.

Similarly, the model of 1/N can be used to extend to the partnership operation of the company. There are n partners, and each partner can directly control * * *, and the specific liquidation can be clear at a glance.

3. Fund supervision: This is the most direct function of multiple signatures. A sum of money needs multiple signatures to be used, and no one can directly use the funds. As long as the scale mode of multiple signatures is flexibly set, many problems in life can be solved.

For example, if a couple wants to reserve an education fund, and no one can move before their children go to college, then the mode of multiple signatures can be changed to 2/2, which not only limits both husband and wife, but also increases the difficulty of hacking.

Multi-signature technology is a reliable and effective security technical guarantee. Whether it is digital currency trading platform, online wallet or the third-party digital currency hosting operation organization, in order to increase the trust of customers, multi-signature technology will be applied to them. After all, the safety of funds is an important guarantee of reputation, and it is also the first consideration for users.
