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

The final outcome of the POR is a binary determination of solvency – whether the exchange’s assets surpass its liabilities. FTX’s collapse in November 2022 and Binance, another crypto exchange, stressing the need for transparency are among the factors behind this shift. By providing a verifiable record of reserves, it becomes easier for regulators to monitor and enforce financial regulations. This helps in preventing fraudulent activities, money laundering, and other illicit practices. In traditional and digital financial systems, a lack of transparency and certainty about reserve levels can lead to panic. Proof of reserves contributes to the overall stability of the market by reducing the risk of a https://www.xcritical.com/ liquidity crisis.

Proof of Reserve for Off-Chain Assets

Exchange Balances are often more dynamic as they represent a more comprehensive set of addresses, while proof-of-reserve addresses are often only a small subset of (cold) wallets. Below is an example for OKEx, showing Exchange Balances in blue, and Proof-of-Reserves in orange for BTC. It is important to note that proof-of-reserve addresses are included within our Exchange balance metrics. Understanding, and keeping up with these dynamics however is essential, in mobile pow system order to provide the most accurate exchange metrics possible.

Ledn Completes Latest Proof-of-Reserve Attestation

The exchange platform (i.e. Binance) acts as a middleman – it connects you (your offer or request) with that other person (the seller or the buyer). With a brokerage, however, there is no “other person” – you come and exchange your crypto coins or fiat money with the platform in question, without the interference of any third party. When considering cryptocurrency exchange rankings, though, both of these types of businesses (exchanges and brokerages) are usually just thrown under the umbrella term – exchange.

What is Proof of Reserves & Why Is It Important for the Crypto Industry?

Crucially, this proof does not come from a bank or crypto lender, but an impartial independent third party. That means that when a platform offers Proof of Reserves, you will be able to review the report to see whether the platform has sufficient assets to cover its liabilities. With proof of reserves, you can have peace of mind knowing that your funds are always protected and readily available when you need them. So, whether you’re dealing with traditional banks or emerging digital platforms, remember the importance of proof of reserves in safeguarding your financial interests. In order to provide verifiable proof of their reserves, financial institutions or cryptocurrency exchanges may need to disclose certain information about their holdings.

While the process does have some downsides (such as not tracking company liabilities), it can provide customer assurance and bolster their confidence. A crypto auditing company tallies the on-chain holdings of the company with the client assets on its balance sheet. So, to put briefly what proof of reserves is – it’s not just a technical concept; it’s a crucial element for ensuring the safety and security of funds in both traditional and digital financial systems. It provides customers with confidence that their assets are being handled responsibly and protects them from potential fraud or insolvency.

Merkle Trees and Cryptographic Proofs

Ordinarily it means on-chain assets, and client liabilities held in a database. A Merkle Tree is an anonymized proof of client balances, allowing anyone to cryptographically verify that the exchange holds their funds and that their account balances are included in the PoR. To read more about how Merkle Trees could be applied in proof-of-reserves, please check out this Crypto.com University article. Proof of reserve (PoR) is like a receipt that shows a crypto exchange has the digital assets it claims to hold for its users. PoR proves the solvency and liquidity of a centralized custodian and assures investors that the custodian can fulfill their withdrawal requests when the need arises. In late 2022, the FTX collapse raised serious questions about the trustworthiness of centralized exchanges for cryptocurrency.

The Importance of Proof of Reserves for Crypto Lending Platforms

If an entity temporarily borrows funds for the snapshot, then they can make it appear that they are solvent without actually having the necessary means to fully cover potential withdrawals. But the SEC’s guidance is at present voluntary and hardly any exchanges even try to comply with it, no doubt because it is really, really difficult and the company’s profits are at risk. Instead, exchanges and platforms are rushing to implement crypto-tech „proof of reserves” gimmicks that are proof of nothing at all. Whatever the snake oil sellers told you, your deposits are fully at risk and you can lose all your money. Additionally, PoR measures are being actively undertaken by numerous exchanges throughout the industry, so PoR legislation simply codifies an existing process that exchanges have embraced.

Proof of Reserve in Traditional Finance

In March 2022, the SEC published new accounting guidance that aimed to ensure crypto exchanges and platforms maintained full reserves across the entire asset mix. SAB 121 advises crypto exchanges and platforms to record „safeguarding” liabilities and corresponding assets. And it requires any losses due to mismatches between the safeguarding liabilities and assets to be borne by the exchange or platform, not its customers. Proof of reserves as done by exchanges like Binance does not prove that customer deposits are safe. It is smoke and mirrors to fool prospective punters into relinquishing their money, just like claims that exchanges and platforms are „audited” or have „insurance”.

How to Trade Cryptocurrency: A Beginner-Friendly Guide

Pending the release of a frontend feature for users to verify their balance inclusion in ongoing audits, BitMEX currently provides a comprehensive guide for technically-savvy users to audit the exchange’s balances independently. BitMEX also publishes periodic social media updates about the state of its reserves. When combined with a public and legally binding disclosure of liabilities, users can view proof-of-reserve attestations to verify on-chain that the custodian has enough assets to back a third-party audit of deposits. Customers can also easily discover whether assets are being rehypothecated, not backed by a solid basket of assets, or utilized for other high-risk activities that could jeopardize their availability.

Thus, users can easily verify from their accounts that Kraken included their wallet balances in the most recent PoR audit. Users can also obtain their audit record ID to validate it against a database maintained by Kraken’s auditor — the exchange also uses Armanino. Lastly, users can access technical details from Kraken’s proof-of-reserves page needed to reconstruct a Merkle tree to verify their balances.

In this article, we’ll break down what Chainlink Proof of Reserve (PoR) is and how it helps provide stronger security guarantees and more transparency in the cryptocurrency ecosystem. In addition, we’ll also explore the PoR reference feeds already implemented by top DeFi teams and provide context for future use cases and implementations. After the Proof of Reserves procedure, users can independently verify their transactions. The cryptographic nature of this process ensures that any alteration to the data would be instantly detectable.

• Furthermore, Chainlink PoR is also increasingly being used to help secure the minting, redeeming, and burning of wrapped assets.
• While they have their limitations, they provide a valuable mechanism for verifying the solvency of cryptocurrency exchanges and custodians.
• And it requires any losses due to mismatches between the safeguarding liabilities and assets to be borne by the exchange or platform, not its customers.
• 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.

For instance, window dressing wouldn’t help with a daily or biweekly PoR attest, as is done by certain exchanges. However, cryptocurrency users have a revealed preference for custodial ownership, at least for a portion of their coins. By encouraging custodial exchanges to adopt PoR, I am hoping that user assurances at custodial exchanges can be bettered. I am aware that the term is used generally to refer to related procedures.

Binance moved to quell concerns over its state of finances by drafting the South African arm of the international audit, tax, and advisory firm Mazars to prepare an additional proof of reserve report. Exchanges can also use Chainlink’s system to provide security around the guarantees that they cannot issue more tokens than assets stored in reserves. For a full comparison of all proof-of-reserves and exchange balances for each individual exchange, kindly use our Workbench in Studio. Comparing proof-of-reserves and exchange balances, there are a few notable observations, with a few examples shown below. Chainlink Proof of Reserve utilizes the largest decentralized collection of security-reviewed and Sybil-resistant node operators in the industry to acquire and verify reserve data. Prove onchain and offchain collateral reserves to help mitigate risk and protect users from unexpected fractional reserve activity.

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. PoR seems like a foolproof solution to verifying the trustworthiness of crypto exchanges and stablecoin issuers, but there are weaknesses to this strategy. Although PoRs often reveal valuable info to traders, these reports don’t always tell the whole story. And it’s not just centralized crypto platforms traders expressed concerns over. They also worried whether there were tests to prove protocols in decentralized finance (DeFi) take proper precautions with their users’ assets.

Instead, the centralized exchange keeps control of the private keys on their platform, meaning they can revoke access to your account at any time. To solve this problem, proof of reserves audits use a data structure called a Merkle tree to establish a firm’s debt without publishing anything customers might not want to share. The blockchain is transparent, meaning everyone can track every transaction in that account’s history. Accordingly, the only thing an exchange must do to prove ownership of its assets is to prove ownership of its wallets. Since all centralized exchanges can keep their financial sheets private, the customer has no idea what’s happening to their funds.

In light of the FTX demise, many players in the centralized exchange space and others have quickly established proof-of-reserve initiatives. The specifics of each proof-of-reserves program tend to vary, with many different approaches being adopted. In Crypto.com’s decision to disclose its wallet addresses, it revealed that 320,000 ETH was sent to Gate.io on Oct. 21, 2022. Crypto.com and Gate.io announced that the transaction was a mistake, and the funds were later returned. Many speculated that these funds were used to top up Gate.io’s books, however, the exchange debunked the notion by asserting their latest snapshot was completed on Oct. 19, 2022, two days prior to the mistaken transfer. 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.

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. After determining an exchange’s liabilities, auditors focus on the assets a crypto exchange holds in reserve. Typically, CEXs provide the public key addresses for their crypto wallets, and auditors scan the virtual currencies in these CEX accounts.

The practicality of using PoR lies in the use of distributed ledger technology as the basis, which a priori enables audits of any class, any crypto entities in the market within any specific conditions with 100% probability. Proof of Reserves (PoR) is a way to ensure that a platform holds enough assets to cover all of its client account balances. To read more about what PoR is and how it works, please check out this Crypto.com University article. Proof of Reserves (PoR) is an audit that aims to prove that a custodian holds all its clients’ funds securely. In the field of cryptocurrencies, PoR is vital for ensuring that all funds on an exchange are fully backed by actual assets.

These leaves are then paired together to form hashes, which are then further hashed until a single node remains, known as the “root”, which sits at the top of the Merkle tree structure. The root lets auditors quickly confirm that the rest of the information contained in each leaf and hash is accurate and has not been tampered with. If any account balances have been manipulated, the Merkle root would be different.
