Asset tokenization is one approach to solving this fundraising problem. Token offerings have played a big part in the growth of the cryptocurrency market. This works by creating digital ownership tokens that can be used to fractionize (or divide) ownership of an asset. Brickken has developed a tokenization protocol and interface to help companies create equity-equity models. These tokens can be tokenized into digital tokens, with each token representing a percentage stake in the building. The platform is currently working on bringing this technology to the mainstream.
