And will the emergence of these direct sales platforms de-intermediate second-hand housing transactions in the future?

Regarding this issue, we need to note that in the context of possible de-intermediation of second-hand housing transactions in the future, in addition to direct sales platforms, more reasons come from the development of blockchain technology. As blockchain technology becomes more mature, a new real estate platform called "Blockchain Real Estate Transaction Registration Platform" has begun to emerge, and its biggest feature is that it completely records housing transaction information on the blockchain. Let buyers and sellers have more security for each other.

From this perspective, the scenario in which second-hand housing transactions may be completely de-intermediated in the future is rather confusing. Because "complete deintermediation" does not mean "cancel the existence of brokers" or "cancel intermediary services", but means that house buyers and house sellers complete the house buying and selling process more directly through transactions on the blockchain platform. , and have more effective protection in terms of information.

But in any case, from the perspective of consumers, the impact of such deintermediation on consumers in the future will be extremely profound. On the one hand, based on blockchain registration, consumers can obtain a more convenient, secure and transparent housing transaction experience. For example, in house purchase and sale transactions, such a system will realize mutual supervision and use blockchain to eliminate unnecessary intervention by intermediaries. On the other hand, it will make consumers' housing transactions safer, and records of fraud that cannot be related to disintermediation will be completely recorded on the Bingzhi blockchain to protect consumers' legitimate rights and interests from infringement.

GeneralTaken together, the emergence of second-hand house direct sales platforms and the gradual maturity of blockchain technology will have a profound impact on second-hand house transactions in the future. Second-hand housing transactions may be de-intermediated in the future. In this context, consumers can obtain a more transparent, convenient and secure housing transaction experience, which will expand the development space of China's real estate market and help China's real estate industry become healthier and more stable.
