 # zk-SNARK & MerkleTree Proof of Solvency
 
-This project aims to explore encrypted technology based on zk-SNARK and MerkleTree to achieve the goal of bringing digital currency exchanges closer to decentralization. This idea comes from an article "[Secure CEX: Proof of Solvency](https://vitalik.ca/general/2022/11/19/proof_of_solvency.html)" by Vitalik Buterin, the co-founder of Ethereum.
