blockchain: blockchains are novel application modes of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like. In short, the blockchain is a distributed shared ledger and database, and has the characteristics of non-falsification, whole trace, traceability, openness and transparency.
Bond underwriting: the investment bank accepts client commission, sells bonds to the hands of institution investors and public investors according to the client requirement, and realizes the puzzle bottom and behavior or process of the client funding. It is the bond issue for the issuer, i.e. the issuer invites the investor to issue legal actions representing bonds of certain crediting and redemption conditions in accordance with the procedures prescribed by law for the purpose of lending funds.
The underwriting group and the protocol: for securities with a particularly large issue volume, such as national debt or bulk stock issue, a contractor is often reluctant to solely take on the issue risk, and a contractor group is organized, and a plurality of organizations together act as contractors, wherein one or more main contractors are often distinguished, the publisher and the main contractors sign a main contractor agreement, the main contractor performs the liability in the agreement with the publisher, and the main contractor signs a contractor agreement with other contractors (distributors) in the group, and the other contractors in the group perform the liability in the agreement with the main contractor.
As described above, in the existing contractual agreement mode, the distributor, the master contractor and the distributor need to communicate offline, and complete the contractual and contractual group construction after the modification and agreement of the related agreement document discussion. The process involves multiple participants, the roles are different, the authorities of different roles to different protocols are different, the manual management is complex and the efficiency is low, and the timely sharing of protocol files and the transparent information disclosure are difficult to realize. And if the protocol is stored in a single system, the protocol is easy to steal users, steal and tamper with file information after being broken by hackers.
