The primary benefit of proof of reserves is enhanced transparency and trust, which in light of recent events, may be critical to restore badly shaken consumer confidence in custodial wallets and exchanges. If users don’t have faith that their funds are secure and readily available, it’s difficult to imagine a future for these services. Proof of reserves is becoming more and more popular, especially with the November 2022 downfall of the FTX crypto exchange and recent comments from crypto exchange Binance about the importance of transparency. It also will become important as regulators look to set industry standards to protect proof of work cryptocurrency consumers, as proof of reserves is a secure and transparent way to ensure that customer funds are safe. However, with proof of reserves, users can be assured of the solvency of the institutions they engage with, minimizing the likelihood of market-wide disruptions. This stability is crucial for the continued growth and adoption of digital assets and the broader financial ecosystem.
Challenges Faced by Crypto Exchanges in Proving Their Reserves
Despite rumors that the exchange was https://www.xcritical.com/ insolvent, Huobi became one of the first exchanges to provide a full Merkle Tree Proof of Reserves audit. The exchange’s main wallets now hold more than 204,000 BTC and 1.22 million ETH — making it among the largest holders for both. On November 11, 2022, Binance became the first cryptocurrency exchange to post its provisional Proof of Reserves. In the aftermath of its collapse, it is still unknown just how many major industry players had significant exposure to FTX and may be forced to shut down operations. Concentrated withdrawals can lead to a bank run, which may result in a loss of user assets.
- When it comes to ensuring the safety and security of funds in the world of crypto, proof of reserves is presented with a twist.
- OKX has not yet provided a full proof of reserves, but it did provide a list of 23 Bitcoin addresses and 13 Ethereum addresses containing 69,000 BTC and $2 billion in ETH/ERC20 tokens respectively.
- Undeniably, an audit firm supervising a PoR helps provide assurances that the liabilities were extracted faithfully – but it isn’t the be all end all.
- For exchanges and wallet providers, engaging in proof of reserves is a signal of trustworthiness and demonstrates a commitment to transparency.
- In a nutshell, a third-party audit involves hiring an external, reputable auditing firm to conduct a thorough examination of a company’s financial records and assets.
- As a result, customers are demanding centralized exchanges go through the appropriate methods of auditing.

PoR helps to increase transparency and accountability in the industry, as well as reduce the risk of fraud and insolvency. By performing a PoR audit, the entity can demonstrate that it is operating in a transparent and trustworthy manner. Another important result of Proof of Reserves is that it creates a safe and healthy ecosystem. At its core, Proof of Reserves is a self-regulatory practice that promotes openness by requiring exchanges to regularly disclose their reserve assets to the public.
Integrate transparent verifications of reserve assets
Similarly, in the realm of digital assets and cryptocurrencies, proof of reserves plays a crucial role in maintaining the integrity of the platform. By implementing proof of reserves, crypto platforms can provide evidence that they possess the assets they claim to hold on behalf of their customers. At dYdX, we take extreme care to provide eligible traders a safe derivatives trading experience in DeFi. Since our launch in 2018, dYdX has never lost or put users’ funds at risk, and we consistently publish open-source third-party code audits with the firms PeckShield and Zeppelin Solutions. Furthermore, there’s no need to solely rely on proof of reserves because you can audit the dYdX smart contract in real time by visiting Etherscan.
How Does a Proof of Reserves Crypto Audit Work?
It’s just that consumers of the PoR are placing their trust more in cryptography rather than the reputation of an audit firm. Undeniably, an audit firm supervising a PoR helps provide assurances that the liabilities were extracted faithfully – but it isn’t the be all end all. By using a Merkle tree to encrypt blockchain transaction data, users can easily verify that the exchange holds their funds both securely and privately.
Some, like Gate.io, opted for auditor-assisted proof-of-reserve validation, while others, such as BitMEX, said they will attest to the reserves themselves. Canada-based bitcoin lending platform Ledn implements a proof-of-reserves scheme through Armanino. The program, launched in January 2021, makes Ledn the first lending platform to provide transparency.
A far more potent trust signal would entail allowing depositors to individually verify that their deposits genuinely exist under the control of the exchange. If we let a commitment to perfection stall the adoption of processes like PoR, we will likely end up with a much worse situation where onerous, top-down regulation is imposed on exchanges. I always prefer proactive industry-driven self-regulation to state regulation, and I think you should, too.
As these audits are commonly done by a centralized third party, they can be lengthy, time-consuming, and require manual processes. In this case, you can recognize the individual account responsible for depositing the assets with the help of unique digital signatures. Verifying individual contributors involves matching the digital signatures with Merkle tree records. The next step of signature verification involves checking whether the balances of the individual are equal to the balances visible in the Merkle tree. The Merkle tree can detect changes in individual balances through drastic modifications in the data structure.
We are working with Mazars Group to include additional tokens, protocols and networks, including Cronos (CRO) and VeChain (VET), in the subsequent verifications. The world’s continued transition to cryptocurrency requires a foundation built on trust. That’s why compliance, security, and privacy have been our core focus since day one.

For example, Binance is based in Tokyo, Japan, while Bittrex is located in Liechtenstein. While there are many reasons for why an exchange would prefer to be based in one location over another, most of them boil down to business intricacies, and usually have no effect on the user of the platform. To sum up, while proof of reserves is an important concept for ensuring the safety and transparency of funds, it does face certain challenges and limitations. Suppose you want to prove that your account balance of 10 units is included in the Merkle Tree. First, you would need to provide the root hash of the tree, which is publicly available. To put it differently, demonstrating proof of reserves plays a crucial role in preventing fraudulent activities.
If financial agents (custodians) hold client reserves in cryptocurrencies, they must also prove ownership of the keys to their accounts holding the digital assets. These procedures are mandatory and help to determine with 100% probability the level of trust of the crypto company in terms of holding reserves. Within the blockchain space, proof of reserves is commonly known as an independent verification that enables centralized exchanges to publicly report the value of their reserves and prove their solvency.
Conversely, low market liquidity means lower trade volumes, fewer investors, and consequent instability in the market. In these conditions, there is more risk of market manipulation because a large purchase or dump of a low-liquidity crypto asset can lead to a snowball effect and massively influence trade patterns going forward. Developing and maintaining such systems can be resource-intensive, especially for smaller institutions or startups with limited financial and technical capabilities. Therefore, while proof of reserves is desirable, not all organizations may be able to implement it with the same level of sophistication. At the very bottom of the tree, we have the leaves (leaf nodes), which represent individual pieces of data, such as individual account balances or transaction details.
Crypto exchanges have traditionally been secretive about the blockchain addresses, holdings, and wallet management practices that control customer funds. However, in the aftermath of the FTX collapse in November 2022, this appears to have started changing. FTX’s collapse elicited growing calls for centralized exchanges (CEXs) and custodial crypto services to prove that they actually hold the customer funds and aren’t deploying them elsewhere. Industry leaders use Chainlink Proof of Reserve for its unmatched security, reliability, and compatibility. Integrate the most reliable proof of reserves solution today for automated verifications that provide unparalleled transparency to your users.
The auditor then aggregates them into a cryptographic Merkle tree that produces a Merkle root — a cryptographic hash that uniquely represents a combination of all user balances. Using the Merkle tree technique, auditors are able to quickly and accurately pore over immense amounts of account holder data without compromising privacy or security. It also lets users hash their own user ID and account balances so they can find them in the tree, allowing individuals to verify for themselves that their funds are right where they’re supposed to be. Financial statement (FS) audits are slow, expensive, infrequent, and very broad in scope, covering far more than just reserve management.
As companies engage in third-party audits, they can demonstrate their commitment to transparency and accountability. These audits provide reassurance to customers that their funds are held by a trustworthy entity and that the reported reserves are accurate and verifiable. Furthermore, the blockchain allows anyone to track the exchange’s wallet transactions — flagging any suspicious activity, such as transfers of large volumes of data, without waiting for another audit. Some exchanges also offer “self-assessment” audits within their platform, instead of using block explorers. Through these self-assessment audits, users can validate if the exchange still holds their funds at any given time. A centralized exchange lets you use an account with the premise that, unlike the bank, they will not lend or use customer assets.
Transparency in transactions with customer assets is one of the most important points when it comes to ensuring their safety. On the other hand, the PoR mechanism can be applied to conduct financial audits of any crypto industry participants, be it cryptocurrency product companies, crypto wallets or stable coins. The versatility of this method has no limits and can become an important aspect of using blockchain technology to enable independent audits of any structure. Proof of Reserves is the idea that custodial businesses holding cryptocurrency should create public facing attestations as to their assets, matched up with a proof of user balances (liabilities). Ordinarily it means on-chain assets, and client liabilities held in a database.
The process typically starts with the institution providing detailed documentation of its assets. The auditor then conducts a thorough examination to ensure that the reported holdings match the actual funds or assets held by the institution. Once the audit is complete, the auditor issues a report confirming the institution’s solvency and compliance with reserve requirements. This verification process adds an extra layer of credibility and reassurance to the proof of reserves mechanism.
PoR helps users ensure the security and trustworthiness of CEXs and other custodial crypto services. 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. For modern PoR like the ones done by Derebit of BitMEX, the entire liability set is released, so there’s no real uncertainty around the completeness of liabilities.
