KILT's original White Paper from May 2019 details the concept and technical implementation of KILT Protocol. In January 2020 the White Paper was updated with new text addressing areas such as the token economy, system architecture and nested claim types (CTypes).
The KILT Coin Metrics paper, published in August 2021, focuses specifically on the token economy, covering areas such as distribution and KILT Coin utility. KILT tokenomics were intentionally designed with low inflation in order to be sustainable in the long term.
