tZero

tZero is a blockchain-based platform that allows for the issuance and trading of digital securities. It was created by Overstock.com, a major online retailer, in 2018.

tZero is designed to be a more efficient and secure way to trade digital securities than traditional methods. It uses blockchain technology to create a tamper-proof record of all transactions, and it also offers a number of features that are not available on traditional trading platforms, such as the ability to trade securities 24 hours a day, 7 days a week.

tZero has been praised by some for its potential to revolutionize the way that digital securities are traded. However, it has also been criticized by others for its lack of regulation.

In 2019, the Securities and Exchange Commission (SEC) issued a warning to investors about tZero, stating that it was not registered as a securities exchange and that investors should be aware of the risks involved in trading digital securities.

Despite the SEC's warning, tZero has continued to grow in popularity. In 2020, it processed over $1 billion in trading volume.

It remains to be seen whether tZero will be able to overcome the challenges it faces and become a major player in the digital securities market. However, it is clear that it is a platform with the potential to revolutionize the way that digital securities are traded.
