Solvency, in finance or business, is the degree to which the current assets of an individual or entity exceed the current liabilities of that individual or entity.^[1] Solvency can also be described as the ability of a corporation to meet its long-term fixed expenses and to accomplish long-term expansion and growth.^[2] This is best measured using the net liquid balance (NLB) formula. In this formula, solvency is calculated by adding cash and cash equivalents to short-term investments, then subtracting notes payable.^[3] There exist cryptographic schemes for both proofs of liabilities and assets, especially in the blockchain space.^[4][5][6]
