The peculiarity of bank guarantees is that they cannot be depreciated under any circumstances. The smart contract program provides for an increase in the value of tokens depending on the amount (authorized capital) of the bank's deposit. The higher the deposit, the higher the cost of the token.

This is entirely unworkable as a bank. A bank with no central management will fail. Banks make money by lending depositor assets and collecting more money when the loans are paid back. This necessitates a central administration to vet investment plans by people seeking loans and assessing the viability of those plans so the borrower has the ability to pay back the loan. What is described above, where people just invest money and magically make more money because “smart contracts” is not a bank, it’s a Ponzi scheme.
If you want to be a part owner of a bank, join a credit union. They’re owned by the members and they actually function as a bank WITH a central administration, which again is necessary.
An excerpt from the project. http://prosh.ru/smartcontract.html
ETH-WORLD tokens are very attractive for the bank as they are secured and have constant growth and cannot be devalued. The bank can issue an interest-free perpetual loan secured by the client's ETH-WORLD (Islamic version of lending), although there may be other conditions. The bank does not have access to the client's ETH deposit, and in case of non-repayment of the loan, it can only sell smart contract tokens, and ETH will remain in the deposit blocked at the address (account) assigned to the client. Such an insurance scheme against losses in case of ETH volatility is very interesting and can attract a large number of ETH holders, which in turn will increase the total ETH deposit and, accordingly, the cost of ETH-WORLD tokens.
