On the opposite hand, if the PoRs present that the exchange’s holdings are well-diversified and over-collateralized, users can believe within the trade. To remedy this problem, proof of reserves audits use a knowledge structure known as a Merkle tree to determine a firm’s debt without publishing anything customers may not wish to share.

In the context of proof of reserves, a Merkle tree can be utilized to show the existence of a person’s deposit inside the trade’s general holdings without revealing the complete list of deposits.
A Merkle tree is a data construction created by repeatedly hashing (transforming plaintext to an almost irreversible value) a large information set.

Investors can rely on PoR verification to watch activities in their individual accounts and acquire readability on how the custodian is managing their funds.

For example, on Binance, you’ll have the ability to select the “Audit” menu and examine if your account participated within the development of the Merkle tree.
BGD Labs integrated Chainlink PoR into Aave on Avalanche to assist ensure wrapped tokens in Aave markets on Avalanche are sufficiently collateralized.
