No presence of intermediaries
As already mentioned, the absence of intermediaries makes the process much easier and faster. Now there is no need to seek help from a lawyer. Everything follows the pre-written code.
Safety and confidentiality
All the contracts are stored in the blockchain, in an encrypted form. The goal of the system is that no one can change the smart-contract or replace the data. In addition, private keys are used for signing, which increase the level of security.
Paperwork takes a long time. The use of blockchain smart-contracts significantly speeds up the process of concluding transactions.
Smart contracts exclude intermediaries from the business process. Once written, the program can be used for different transactions for different users.
