Securities are shares of stock in a publicly traded firm. Many of the instruments we see today — stocks, bonds, options — might be called securities under this criteria. If an instrument meets the criteria for security in a specific jurisdiction, it is subject to rigorous regulatory inspection. What’s a security token ? A security token is a blockchain-based token that represents a stake in an external organization or asset. These can be issued by enterprises or governments and perform the same function as their counterparts (i.e., stocks, bonds, etc.).
