I recently learned about the fundraising mechanisms on the blockchain, and it turns out there are significant differences between STO and ICO that many people might not understand. So, STO stands for Security Token Offering, but this is not just a fancy version of an ICO.

The difference is quite fundamental. An ICO issues digital tokens that are often just speculative assets without real ownership guarantees, whereas STO is different. STO issues tokens that truly represent securities—such as shares, bonds, or other financial instruments. That’s why STOs must comply with strict securities regulations, like SEC rules in the United States or securities authorities in other countries.

Because of its stronger legal basis, investors participating in STOs actually have real rights. For example, the right to receive dividends, ownership in the project, or other benefits that are legally protected. This is a far cry from ICO tokens, which are often purely speculative.

Blockchain technology is still used to record and trade these tokens, so transparency and efficiency remain. But what sets them apart is the regulatory layer and investor protections on top.

The use of STOs is quite broad. Startups can use them for more structured fundraising. Traditional companies can also issue digital securities through STO. And for individual investors, this opens up investment opportunities that are more transparent and well-documented compared to traditional methods. So, in essence, STO is an evolution of blockchain fundraising that is more serious and regulated.
