What is a security token offering or STO?

Similar to an initial coin offering (ICO), an investor is issued with a crypto coin or token representing their investment. But unlike an ICO, a security token represents an investment contract into an underlying investment asset, such as stocks, bonds, funds and real estate investment trusts (REIT).

The ownership information of the investment product is recorded on a blockchain. When you invest in traditional stocks, for example, ownership information is written on a document and issued as a digital certificate (e.g. a PDF). For STOs, it’s the same process, but recorded on a blockchain and issued as a token.
