Banks and cryptocurrenciesToday, some processing services are trying to use a limited number of cryptocurrencies
as a payment tool.
But the banking sector is not in a hurry to join the use of cryptocurrency.
Why it happens?
The fact is that for a bank to use cryptocurrency, in contrast to the processing service,
you need to take it to your balance. That is, the cryptocurrency should be on the balance
sheet of the bank as a deposit.
As we know, any banking transaction is signed and identified.
Since cryptocurrencies have the property of anonymity, therefore the bank cannot accept
cryptocurrency on its balance sheet.
And we see something like this:
How can this problem be solved?
Suppose that there is a way to sign transactions in a cryptocurrency:
1. The user sends the cryptocurrency to the address of the bank, signs the transaction
with his identification key, which the bank has given him.
2. The bank goes to certify this transaction and credits the cryptocurrency to the deposit
account of the client.
In this example, we see a variant of legal transfer of cryptocurrency to a bank deposit.
To implement such a solution, it is necessary to implement a single strategy for all
cryptocurrencies.
At the moment, in the network “Ethereum” in the form of “ERC” coins there are stable
coins that are already successfully used by processing services, as well as wrapped
tokens there are cryptocurrencies such as “BTC”, “BCH”.
Most likely in the near future we will see other cryptocurrencies in the form of ERC
wrapped tokens.
To solve this problem, we use the “ZENITH Protocol”, with the help of which it is possible
to sign transactions of any “ERC” coins.
And we get the following result:
