Once you have defined your goals, you need to choose your metrics to measure and demonstrate your impact. Metrics are quantitative or qualitative indicators that show the progress and performance of your blockchain solutions. Depending on your goals, you may choose different types of metrics such as technical metrics, which measure the technical aspects of your blockchain solutions like transactions, throughput, latency, security, scalability, and reliability; business metrics, which measure the business aspects of your blockchain solutions such as revenue, cost, profit, market share, customer satisfaction, and retention; and social metrics which measure the social aspects of your blockchain solutions such as social impact, environmental impact, governance, transparency, accountability, and inclusion. Technical metrics can help you assess the efficiency and effectiveness of your blockchain solutions and identify areas for improvement. Business metrics can help you evaluate the economic and competitive value of your blockchain solutions and demonstrate the return on investment (ROI) and value proposition to your stakeholders. Social metrics can help you measure the ethical and societal value of your blockchain solutions and demonstrate the social good and positive change that you are creating with blockchain.
