What is Proof of Reserves and How Does It Secure Your Funds?

Evan Jones was introduced to cryptocurrency by fellow CryptoVantage contributor Keegan Francis in 2017 and was immediately intrigued by the use cases of many Ethereum-based cryptos. For more information about different exchanges’ proof-of-reserves, please see below. And lastly, because PoR is only one piece of the puzzle, it should be paired with other requirements that give https://www.xcritical.com/ end users strong guarantees around custody.

Which tokens are included in the verification?

In the case of a publicly traded company with quarterly audited proof of reserves crypto exchanges financials and strong controls, depositors may not seek the additional assurances of a PoR. There’s already a strong institutional architecture which makes it hard for the exchange to lie about its financials. However, the set of exchanges that this caveat applies to is very few — in the U.S., only one, as far as I can tell. Generally, the status quo is for crypto exchanges and platforms to not be publicly traded. They also have trouble securing financial statement audits from Big Four firms. Additionally, a PCAOB financial statement audit doesn’t really focus on reserves.

Tailored solutions for every platform

Proof of reserves (PoR) is the process of verifying that the customer assets held by a cryptocurrency exchange or financial institution correspond to the number of assets the company holds in reserve on behalf of the customers. PoR has been highly publicised as the primary solution for crypto investors to make sure that their funds are being secured appropriately. It’s also a useful tool for crypto platforms as it provides a way to prove they are solvent i.e. possessing enough assets to cover trades and withdrawals. These auditors specialize in digital assets and thoroughly examine the financial records and reserve balances of cryptocurrency exchanges taking into consideration all the risks related to crypto assets[2].

Proof of Reserve in Traditional Markets And Tokenized Real-World Assets

Therefore, while proof of reserves is desirable, not all organizations may be able to implement it with the same level of sophistication. By verifying and validating these reserves, users can have peace of mind, knowing that their assets are protected and won’t disappear overnight due to mismanagement or bankruptcy. Now that the question of what is proof of reserves has been answered, it’s time to understand why this concept is so important. As a result of the various collapses to occur in 2022 (Celsius, Voyager, FTX, etc.), many centralized exchanges have expressed an intent to be more transparent moving forward. The easiest and most obvious way of doing this right now is to issue reports which are being called ‘Proof-of-Reserves’ – the purpose of which is to assuage investors by showing that their funds are not being mishandled. Validate asset holdings across interconnected systems, ensuring composability and managing risks like flash loans while maintaining transparency for users.

Every node in the Merkle tree has a unique hash, representing a portion of the information as a whole. However, in this data structure, no single node stores the information for any single wallet. Instead, the data is split across the whole tree, with each node inheriting a piece of information from its parent.

Different jurisdictions have varying requirements and regulations concerning financial transparency and reporting. Also, you know that there are many significant benefits and implications it brings to the financial world, which I’ve already talked about. Then, you would provide a series of hashes, known as “proof hashes”, that form a path from your account balance leaf to the root of the tree. Cryptographic proofs provide a way to mathematically prove the integrity of data.

Noncustodial exchanges, which don’t hold user funds, operate differently. They don’t require Proof of Reserves because users control their assets directly. Chain assets refer to cryptocurrencies that are actively traded on public blockchains. To ensure the accuracy of these assets in the reserve count, Merkle Tree Analysis is applied.

Deribit, a cryptocurrency options exchange, became one of the first crypto derivatives trading platforms to provide Proof of Reserves. The above graphic representing Bybit’s reserves illustrates the problem neatly, in that there’s a big “N/A” in the Total Debts box. As such, what these reserves show is that the exchange has some cryptocurrency, and pretty much nothing else. PoR is still evolving technologically, so don’t fixate on one specific implementation over another.

Regular and thorough audits are necessary to ensure that the claimed reserves match the actual funds held by the institution. However, conducting these audits frequently can be expensive and time-consuming. Adhering to these regulations while implementing proof of reserves can be a demanding task for financial institutions. Striking a balance between fulfilling legal obligations and maintaining operational efficiency can be a delicate process. The blockchain, as you may know, is a decentralized and transparent ledger that records all cryptocurrency transactions.

It’s commonly said that Proof of Reserves only pertains to assets, not liabilities. In the wake of FTX, some exchanges did informal asset attestations as a short term stopgap measure in which they shared coldwallets without corresponding liabilities. PoR has always meant proving ownership of client assets and demonstrating outstanding liabilities owed to clients.

Debates often surface regarding the true efficacy of Proof of Reserves, particularly concerning off-chain assets. Critics argue that these processes can be manipulated or misrepresented, leading to a false sense of security for investors. While Proof of Reserves offers numerous benefits, it does have its risks. Some cryptocurrencies do not have clear transaction histories or may be locked in smart contracts, complicating the proof process.

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. So, proof of reserves brings a range of benefits to the financial industry. It establishes transparency and trust, protects against insolvency, prevents fractional reserve practices, improves market stability, and strengthens regulatory compliance.

By analyzing the blockchain data, interested parties can confirm whether the exchange’s claimed reserves align with the transactions on the public ledger. In the cryptocurrency realm, a wallet address serves as a unique identifier for a digital wallet. It consists of a string of characters, similar to an email address, but instead of receiving messages, it receives and holds digital assets like Bitcoin or Ethereum. In traditional banking, financial institutions are required to hold a certain percentage of their customers’ deposits as reserves. This ensures that they have enough liquidity to fulfill withdrawal requests and other obligations. Whether you’re entrusting your hard-earned money to a traditional bank or a digital asset platform, you want to ensure that your funds are always protected.

This transparency helps mitigate fears surrounding issues like insolvency or mismanagement. Investors are often more likely to engage with platforms that openly share their financial status, leading to a healthier marketplace. We are devoted to regularly renewing our comprehensive Proof of Reserves audit to ensure continuous safety and transparency for our clients. The digital signatures provided by users are cross-referenced with the Merkle tree records to ensure consistency. These balances are then structured into a Merkle tree, a cryptographic structure comprising authenticated branches connected through hash codes. The third-party accountant or accounting firm initiates the process by capturing an anonymized snapshot of the custodian institution’s balances.

Put simply, an institution showing Proof of Solvency, via the audit of its assets against its liabilities, can guarantee users access to their assets. This way, if just one transaction is modified, the hash will change – not just for that specific node – but also its parent and grandparent nodes, all the way up to the Merkle root. This makes the system unhackable, secure, and a reliable, real-time account of a platform’s holdings. The auditors then use the data from this verified wallet to form a part of their report. While that may not seem immediately concerning, it means if the exchange fails, you lose your funds.

Additionally, the transparency afforded by proof of reserves helps to prevent or detect instances of fractional reserve practices, where an exchange claims to hold more funds than it actually possesses. By allowing external scrutiny, exchanges deter fraudulent activities and promote a healthier cryptocurrency ecosystem. It ensures that the financial institution or platform has enough assets to cover the liabilities owed to its customers.

It is fairly mature from a technical perspective, with lots of academic and practitioner debate, and has undergone significant refinement in its decade of life. Newer innovations such as ZK liability proofs have considerably enhanced the privacy of PoR (which was historically the biggest reason exchanges didn’t undertake it). Policymakers owe it to the industry to engage with the reality of this proactive, self-regulatory phenomenon.

Requiring financial institutions and cryptocurrency exchanges to prove they hold enough assets to cover their customers’ deposits offers a layer of trust and transparency. This reassures individuals that their hard-earned money is not being mismanaged or lost due to insolvency. When it comes to ensuring the safety of your funds, third-party audits play a crucial role in the proof of reserves process.
