I recently talked with a friend about the various ways companies raise funds in the blockchain era, and it turns out many are still confused about what exactly an STO is. So today, I want to share a brief explanation.

STO stands for Security Token Offering, which is basically a new way to issue digital securities using blockchain technology. Compared to the more popular ICOs earlier, STOs have a significant difference—tokens issued in an STO represent real ownership or specific rights, like shares or bonds, not just meaningless digital tokens.

What makes STOs more "serious" than ICOs is their strict regulation. STOs must comply with securities laws in the country where they are conducted, such as the SEC in the United States. This means investors have clearer legal protections, and companies conducting STOs must be transparent and well-documented. This is different from ICOs in the past, which were often chaotic due to lack of regulation.

From an investor's perspective, STOs provide tangible rights—such as dividends, project ownership, or other clear benefits. All of this is recorded on the blockchain, making it transparent and difficult to manipulate.

The practical use of STOs today is quite diverse. Startups can use STOs to raise funds in a more legal and structured way. Traditional companies are also starting to be interested in issuing digital securities via blockchain because of its efficiency and transparency. In essence, STOs are a bridge between the traditional financial world and blockchain technology—offering a safer, well-documented investment opportunity for everyone.
