A security token offering (STO) is a digital representation of a real-world asset designed as a digital token on a blockchain network. STOs are highly regulated and can be a tokenized form of stake in conventional financial assets, including commodities, bonds, stocks, etc.
Unlike initial coin offerings (ICOs), which were an earlier form of STOs, which were highly unregulated and resulted in scams, the regulations around issuing STOs make them more reliable as a form of investment. Security token offerings are digitized and tokenized versions of stake, functioning just like securities, except that they are powered by blockchain technology.
Like conventional securities, STOs are an asset class to invest in potentially. However, they differ from traditional securities as they offer the immutability and transparency of being developed, delivered, and managed on a blockchain network.
STOs could signify a stake of ownership in any asset they represent, similar to stocks and bonds. They also have stricter regulations and laws that they need to comply with, unlike ICOs. Many crypto enthusiasts consider STOs to fall somewhere between ICOs and IPOs, being issued on the blockchain as a stake in any company or entity.
