The US Securities and Exchange Commission approved Blockchain, a blockchain startup, on Wednesday to sell $28 million in digital tokens under Reg A+ regulations. Although the product is similar to an IPO in some respects, there are significant differences. For example, a token buyer will not acquire ownership of the company. Instead, they will get a "featured token" that can be used as currency on Blockstack's network. Blockstack will begin selling SEC-approved tokens on Thursday. This seems to be one of the first token products approved by the SEC in the market. According to reports, the SEC declined to comment.
