The expression "central" in the wording central banks is already suspicious when it comes to the question of issuing a cryptocurrency by a government. But a government could become more credible if it manages all its expenses on a blockchain so that each citizen could always check if the taxpayers' money is consequently used. Instead of issuing a cryptocurrency, the Congress could be suppressed by replacing it with a virtual congress which work would be performed on a blockchain network.

Yes, it is public for other countries. Sukuk is used for huge projects: infrastructure, power plants, Airport, etc... Only big banks like Morgan Stanley, Deutsche Bank, Citibank, Standard Chartered and States could afford to use it because of the huge adjacent costs. People think Sukuk is only for Islamic countries. It originates from there but today it is much popular in the west. Most international Sukuk are listed in London, Luxembourg, and Dublin. But because most of us cannot afford to invest in Sukuk (a single certificate would start from 100 000 USD), most people don't know it. Sakkex will help in decreasing the issuance and management costs by 50% and in initiating the issuance of mini and micro Sukuk so that you, me and others normal people will be able to participate in a Sukuk project.
