sented in this paper. We aim to inspire further exploration in the field of privacy and trust in digital asset platforms.

5.1 Contract

One potential area for future work involves the creation of a smart contract for storing the historical data of a business’s Proof of Solvency. This contract would allow businesses to announce new rounds of Proof of Solvency, set the root of the Proof of Liabilities tree and its associated proof, and also submit proofs related to the Proof of Reserves. It would also perform a final check of solvency, ensuring that the total reserves are at least equal to the total liabilities. This could provide a transparent and verifiable record of a business’s solvency over time, enhancing trust in the platform.

5.2 Custodian Scoring Platform

Based on the protocol introduced in this paper, we could also develop a platform for scoring custodian service providers. This platform would evaluate custodians based on their Proof of Reserves, the frequency of their solvency periods, their historical record of solvency, and other relevant factors. Such a platform could provide users with a transparent and objective way to evaluate the trustworthiness of different custodians, aiding in their decision-making process.

5.3 User Credit

Currently, the Proof of Solvency protocol is focused on businesses, but it could be extended to users as well. With some modifications to the protocol and collaboration from businesses, users could create private proofs that they hold at least a minimum balance in the custody of a specific business during their last submitted Proof of Solvency round. Users could also create proofs for historical balances, such as proving that they had at least a minimum balance for the last five submitted Proof of Solvency rounds by a specific business. This could provide users with a privacy-preserving way to demonstrate their financial stability and creditworthiness.
