Indonesian Islamic microfinance cooperative BMT Bina Ummah has raised 710 million rupiah ($50,000) through the world's first primary sukuk issuance on a public blockchain and also the world's first micro sukuk.
A sukuk is an Islamic financial certificate, similar to a bond in Western finance, that complies with Islamic religious law commonly known as Sharia. Since the traditional Western interest-paying bond structure is not permissible, the issuer of a sukuk sells an investor group a certificate, and then uses the proceeds to purchase an asset, of which the investor group has partial ownership. The issuer must also make a contractual promise to buy back the bond at a future date at par value.(Investopedia)
