Several crypto exchanges, https://www.xcritical.com/ DeFi platforms, and others have implemented proof-of-reserves to reassure users. However, exchanges can still hide their insolvency while appearing transparent using PoR. This is because PoR provides attestations of assets and leaves out custodians’ off-chain activities and liabilities to customers.
Integrate transparent verifications of reserve assets
CoinGecko provides the easiest way to verify an exchange’s proof of reserves (as proof of reserve discussed earlier). However, if you want to dive deeper, you may need to follow exchange-specific procedures or rely on an auditor’s snapshot prepared on a periodic rather than ongoing basis. Unfortunately, many existing PoR techniques fail to factor liabilities into the equation.
Autonomous, reliable, and secure asset monitoring
Yet, the report drew more controversy, with experts stressing that the Mazars report means little without any information about the quality of Binance’s internal controls, such as its systems for keeping accurate books and records. This may potentially lead to a scenario where an exchange uses its proof of reserves to appear transparent without disclosing its true solvency risk. Proof of reserves has been the talk of the town in the wake of the FTX collapse, with the investor community demanding exchanges provide attestations of their crypto holdings. Wrapped token bridges help create more capital efficiency in the DeFi ecosystem but introduce risks through the potential of undercollateralized wrapped assets. Chainlink PoR can be utilized to monitor the collateralization of wrapped assets in wrapped token bridges. Furthermore, Chainlink PoR is also increasingly being used to help secure the minting, redeeming, and burning of wrapped assets.
Why Is Proof of Reserves (PoR) in Demand After FTX Collapse?
If a platform owns $1 billion but owes $5 billion, it has the potential to become insolvent. It relies on voluntary engagement and does not guarantee full transparency of a custodian’s financial situation. However, given the industry’s poor record of transparency concerning customer funds, it is, by many, considered a start to establishing a minimum standard of self-regulation. Moreover, exchanges and lenders are encouraged and free to seek additional regulation to increase their reputation in the market, and in doing so, gain their customers’ trust.
What is Coinbase’s proof of reserves?
Of course, the involvement of third-party auditors moves the platform further away from centralization. A more crypto-native approach would leverage cryptography and algorithms to prove the reserves exist without opening the books to third parties. The 2019 failure of QuadrigaCX also highlighted the issue of crypto exchange insolvency due to the exchange mismanaging client funds. An auditor who undertook a review of the company noted that it had no accounting system nor bank accounts. The failure of the FTX cryptocurrency exchange in November 2022 jumpstarted a wider effort by the industry to assure their users that their funds are safe via PoR initiatives. To be clear, Merkle tree-based proof-of-reserve would not prevent the misappropriation of customer funds completely.
Moreover, as highlighted in a recent WSJ report, the Mazars report was, in fact, a five-page letter rather than a proper audit report. It did not address the effectiveness of Binance’s internal financial-reporting controls, stressing that Mazars did “not express an opinion or an assurance conclusion,” meaning it wasn’t vouching for the numbers. One way to execute an attestation is via a PoR protocol that uses a Merkle Tree proof to integrate large amounts of data into a single hash and verify the integrity of the data set.
A Proof of Reserve (PoR) is an independent audit conducted by a third party to ensure that a custodian (such as a centralized crypto exchange) actually has, in its ownership, the assets it says it has. The collapse of TerraUSD and FTX underscores the crypto industry’s struggles with transparency. Fortunately, proof-of-reserve (PoR) techniques could help increase transparency and reassure users without exposing data or trusting third parties. While many of these systems remain at an early stage, some are starting to address key shortcomings.
It only tracks holdings and would not prevent an exchange from, say, lending money to dodgy borrowers who have no hope of repaying. Issuers minting onchain tokens representing offchain or cross-chain assets can integrate Chainlink Proof of Reserve to help provide additional guarantees that they cannot mint more tokens than assets stored in reserves. Beyond USD-backed stablecoins—which are the most popular pegged assets within the DeFi ecosystem—Chainlink Proof of Reserve feeds can also be constructed to provide collateralization data regarding any type of pegged asset.
By using Merkle tree-based PoR, the auditor can aggregate all the users’ account balance data into a Merkle root (the single hash at the top of the tree). PoR is a form of self-regulation, where an independent auditor generates a snapshot of the custodian’s balance sheet and organizes it using the Merkle tree. A Merkle tree is a data structure created by repeatedly hashing (transforming plaintext to a nearly irreversible value) a large data set. Proof of Reserves (PoR) verification prevents custodians from using users’ deposited assets to acquire loans or make investments.
Centralized exchanges are really convenient for both newcomers and existing traders. They are usually compliant with government regulations and are easy to use, even for beginner traders. They come with customer support teams that can help you out if you run into trouble. Custodial cryptocurrency businesses are the ones that are in possession of their customers’ funds for the d… Centralized exchanges (CEXs) are a type of cryptocurrency exchange that is operated by a company that owns … Proof-of-reserve ensures that a crypto lender does not loan out more money than the collateral it holds, so that its lenders can be compensated in full if anything happens.

Since independent auditors verify their financial statements, users can trust the exchange holds sufficient reserves to cover deposits. In late 2022, the FTX collapse raised serious questions about the trustworthiness of centralized exchanges for cryptocurrency. Events leading to its collapse pointed out misuse of users’ assets, which were in the custody of the exchange. The digital assets deposited by the users did not match the assets in FTX’s custody, with a deficit of nearly $10 billion. During the collapse, FTX experienced a massive surge of users withdrawing their funds. But because of its lack of a proper reserve, the firm couldn’t fulfill users’ withdrawal requests when the users went to withdraw their assets, and it eventually filed for bankruptcy.
First, a snapshot is taken of all eligible users’ Trading, Funding, and Grow accounts, and each user is given a unique anonymous user hash ID. Combining the total sum of all our users’ assets produces a “Merkle root,” a cryptographic signature representing all user holdings. The Merkle Tree Proof-of-Reserve provides an assurance by enabling quick, easy verification of a large volume of data, for the purpose of transparency and customer assurance.
Any tampering with a customer’s account balance would result in a change that cascades up the tree, resulting in a different Merkle root. Throughout this process, customers cannot see the account balances of others, thus preserving privacy. Chainlink Proof of Reserve helps DeFi users get transparency into their risk exposure, increasing confidence in the backing of onchain tokens collateralized by offchain reserves. Publish timely and immutable onchain auditor-verified reports to bring enhanced transparency to traditional verification processes. Released last week, it said that at the time of assessment, Binance controlled in-scope assets in excess of 100% of their total platform liabilities.
Thanks to their security and privacy-friendly features, Merkle trees have been adopted in many Distributed Ledger Technology (DLT) projects, including Bitcoin.

Bidding opened at the guided price of $1.3 million, with subsequent bids ranging from $25,000 to $5000. “It’s two-bed, one bath on about 70 square metres in original condition, but it’s a really good, wide, tree-lined street, and I think that was the appeal for most people,” Ray White’s Ercan Ersan said. By Saturday evening, Domain Group had recorded a preliminary auction clearance rate of 59 per cent from 890 reported results, while 206 auctions were withdrawn.
