The developer, who formalized the code that underlies most of the primary token allocations (ICO), the Ethereum standard ERC-20, proposed a new approach in an attempt to make financing schemes safer for investors.
Speaking in Prague on Devcon4, the annual Ethereum Developer Conference, Fabian Vogelsteller proposed the concept of a "reversible ICO" or RICO that would allow token investors to return their funds at any stage of the project's life. In particular, the concept involves the creation of a special smart contract that allows investors to "cancel their financing obligations".
