Bankex is blockchain protocol and exchange that aims to solve some of the issues related to lack of trust in traditional financial systems. Bankex had one of the largest ICOs in history, where it raised $70.6 million. Bankex facilitates the digitization, tokenization and exchange of physical assets. The company also wants to encourage banks to integrate blockchain. They provide financial institutions with an API that can be used to develop bank-as-a-service (“BaaS”) applications. Bankex's platform would enable decentralized financing that is publicly auditable. This would introduce new sources of capital from real assets, and increase their liquidity. The platform is powered by the Bankex token (BKX).
