COTI is an enterprise-grade fintech platform that empowers organizations to build their own payment solutions and digitize any currency, saving time and money. The core of COTI's infrastructure is the Trustchain, a proprietary consensus algorithm based on machine learning. The Trustchain is based on a multi-DAG (directed acyclic graph) data structure, which works together to increase scalability and process over 100,000 transactions per second (TPS).
