*Problem statement* Individuals suffering from kidney failure today face significant challenges to obtain a transplant. They are placed on a waiting list in hope that a kidney from a deceased donor is a transplant match. However, they do have another option: a living donor; someone they know, family or friend, willing to give them a kidney. Unfortunately, these people may not be a transplant match, however there is a solution called “Kidney Exchange” or “Kidney Paired Donation”. In these programs, if two mismatched pairs (living donor and kidney recipient) can be grouped together to become transplant match, both kidney failure patients can receive a kidney. While a great solution, these programs have a significant pitfall. They are limited in terms of geographical scope.
*Solution* Kidner is a platform that helps healthcare facilities finding match for kidney paired-donation. It’s a global database, Blockchain-based, secured with cryptographic tools. Kidner increases the chance to find rapidly a proper match while being fully protected. Privacy and confidentiality are preserved thanks to encryption tools and certificates are issued by authorized healthcare entities. The algorithm operates in real time and is decentralized.
