That said, the “liabilities” section of GeckoTerminal is often missing, and exchanges have a way to go before providing absolute transparency without third-party auditors. More than $450 billion vanished from the crypto market following the collapse of TerraUSD in May 2022. While many investments carry the risk of loss (including stocks and bonds), these spectacular collapses arose largely from a failure to maintain proper reserves. Another limitation of https://www.xcritical.com/ PoR is scope since PoR only assures a company’s holdings and liabilities (if done right) at a moment in time, and not other risks. Companies can still be vulnerable to other factors such as bad economic environment, poor internal management, or even hacks. The value of crypto assets can increase or decrease, and you could lose all or a substantial amount of your purchase price.
Bring end-to-end transparency to your onchain and offchain reserves
Chainlink Proof of Reserve provides both the growing DeFi ecosystem and the traditional financial system with a way proof of reserve to boost the transparency of their operations through definitive on-chain proof of any asset’s true collateralization. As the smart contract ecosystem grows, it is critical to ensure market failures caused by opaque operational processes and toxic collateral are consigned to history. With Chainlink Proof of Reserve, the DeFi ecosystem is well-positioned to scale and help secure the next generation of trust-minimized financial products.
What is Proof-of-Reserve: Transparency for Crypto Exchange
This revealed a strong indication that their accounts were so closely intermingled with those of FTX that if Alameda Research faltered, FTX would likely falter too. People feared that FTX did not have the assets on hand to cover all customer withdrawals. This event triggered an ensuing wave of customer withdrawals that led to a bank run-like effect, ending with the bankruptcy of FTX, likely permanent loss of billions of dollars in user funds, and crash of the crypto market. For crypto asset PoR, this means an auditor verifies that the on-chain assets held by the company are no less than 100% matching customer assets as shown in their balance at the time of the audit. This can help reassure customers that the company is sufficiently liquid and solvent, and that the funds are accessible to the customers should they choose to withdraw.

Following this model, Proof of Reserve reference feeds can be deployed to track the collateralization and secure the minting of any stablecoin backed by off-chain fiat reserves. Through this data, the economic activity of stablecoins can accelerate within DeFi not only from retail users but also from traditional institutions that are seeking to securely generate yield in the decentralized finance ecosystem. Well, public transparency blocks a crypto exchange from making any secretive financial transactions, such as for example, loaning out more money than the collateral it holds and risking insolvency. Although we use the term “Proof of Reserves” for convenience, the reserve ratios we mentioned above offer a Proof of Solvency.
Leaves and Roots — The Make-Up of a Merkle Tree
The platform may also provide cryptographic proof that the balance of all deposit addresses in the Merkle Tree equals the total cryptocurrency they claim to hold. That way, anyone can verify the platform is holding all customer deposits in reserve. For instance, Binance recently released its Merkle Tree-based proof of reserves system for Bitcoin and Ethereum. During the process of PoR, an exchange provides information to demonstrate its ability to cover user withdrawals with assets held in its reserves. The auditor then publishes its findings for the public, and users can confirm their deposits were included in the audit. PoR is typically performed in specific ways to ensure standardization and trust in the system.
As these audits are commonly done by a centralized third party, they can be lengthy, time-consuming, and require manual processes. Additionally, we delve into the cleanliness and status of a platform’s reserves and how the PoR process works to provide transparency. Finally, we examine measures that cryptocurrency platforms can take to increase transparency and improve customer safety. As cryptocurrency continues to gain popularity, protecting the safety and security of customer funds is crucial. One way to achieve this is through Proof of Reserves (PoR) audits, which provide transparency and verification of a platform’s solvency. Proof of Reserves allows centralized exchanges to provide users and fellow institutions visibility into the state of digital assets on hand, helping assure stability within digital asset markets.
Chainlink PoR can also be used to support the tokenization of other types of RWAs, such as commodities like gold and silver. Paxos and CACHE Gold are using Chainlink PoR to enable anyone to quickly verify on-chain that their tokenized gold products are fully backed by gold reserves held in off-chain custody. The global financial system commonly operates in an undercollateralized and highly opaque manner, creating systemic risks that can result in boom and bust cycles and market-wide failures.
Ideally, users can be assured that exchanges safely hold their assets through verification of PoR. A crypto exchange could lie outright, and a third-party attestor could still uphold the lie. If the attester is corrupt or incompetent, perhaps by overlooking missing wallets or failing to understand how an exchange had structured customer holdings, the whole purpose of proof of reserve would be undermined. There are no formally accepted rules or procedures that define a Proof of Reserves audit. You should not construe any such information or other material as legal, tax, investment, financial, or other advice.

Furthermore, Proof of Reserve feeds can be used beyond the world of DeFi and smart contract applications. For example, they can provide traditional financial institutions with a way to increase trust with customers and counterparties by using Chainlink oracles to publish their audit reports on-chain as an immutable and tamper-proof record. Proof of Reserve traditionally refers to businesses that hold cryptocurrency creating public reports regarding their reserves to prove their solvency to their depositors via an independent audit.
The idea is that, following the publication of a proof-of-reserves certificate, anyone could follow the money and work out how much crypto an exchange holds. In effect, it is a bona fide verification tool to prevent exchanges from surreptitiously running off with customer deposits. The most common way to verify that customer balances are fully backed in the crypto industry is by constructing a data structure called a Merkle tree (using a snapshot of individual customer balances). Events in November 2022, however, saw more trading platforms work towards having their own proof of reserves, which, depending on the exchange, varied in detail. These included Binance, the world’s largest crypto exchange by trading volume, which released a Merkle Tree-based system for Bitcoin and Ethereum, with OKX, Crypto.com, and ByBit taking a similar approach.
Investors can rely on PoR verification to monitor activities in their individual accounts and gain clarity on how the custodian is managing their funds. Therefore, a cryptographic data structure called the Merkle tree (or hash tree) is employed to protect user information. In a Merkle tree, data about each individual depositor (name + balance of deposits) is recorded as “leaves.” Usernames are cryptographically converted into data called hashes to provide a layer of protection.
Asset tokenization projects such as TUSD, PoundToken, and Cache Gold have integrated PoR Secure Mint to employ this standard for tokenized asset transparency, security, and verifiability. Proof-of-Reserves, or short PoR is a publicly shared and verified background check or an independent audit conducted on crypto exchanges by a third-party auditor. For the PoR to work as a true PoS, it’s also crucial for users to be able to check the liabilities themselves against the reserves. While useful, more is needed to re-establish trust in a world where trusted third parties can, all too often, be security holes. Proof of Reserves (PoR) is a method of using cryptographic verification to demonstrate possession of digital assets.
All of these checks and balances ensure that a crypto company has the reserve assets that it needs to serve all customers, and that liquidity is maintained no matter the market conditions. Using the summation Merkle tree approach instead of a simple Merkle tree makes sure the user balance for each user account is part of the hash generation input. It also guarantees the user balance is added from the bottom up to the Merkle tree root to record total assets for all users. Instead, we use the full 32 bytes and make sure of one unique ID for every customer (which we compute based on each unique user ID on OKX).
This allows them to verify that the leaf matches the same Merkle root that was disclosed. Prove onchain and offchain collateral reserves to help mitigate risk and protect users from unexpected fractional reserve activity. Exchanges can also use Chainlink’s system to provide security around the guarantees that they cannot issue more tokens than assets stored in reserves. Paste and save the data as a JSON file, then run the Merkle Validator open-source OKX verification tool.
While these efforts are a leap forward in transparency, many don’t provide any window into liabilities, limiting their usefulness. BitMEX is a notable exception with a Bitcoin proof-of-reserves and proof-of-liabilities system. However, the system remains a work in progress, and the process of computing these proofs is too complex for most users. These companies appear to have a habit of hiding their reserves or outright lying about them. An exchange may have used your money to prop up its failing trading firm, as happened with FTX. They may have accidentally wired hundreds of millions of dollars worth of customer funds to another exchange, as befell Crypto.com, or lost it all in a hack, as happened with Mt. Gox.
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. Because centralized third parties typically conduct this reporting, they can be lengthy, opaque, and time-consuming manual processes.Chainlink Proof of Reserve (PoR) builds upon this concept to provide a customized solution for Web3. It enables seamless, decentralized, and autonomous proof of reserves reporting by verifying collateral amounts and posting that data onchain. With Chainlink PoR, users have more transparency, updates in real-time, and stronger guarantees around the proof of reserves’ accuracy. Chainlink Proof of Reserve provides smart contracts with the data needed to calculate the true collateralization of any on-chain asset backed by off-chain or cross-chain reserves. Chainlink PoR feeds can be used for a wide range of tokenized real-world assets (RWAs), such as real estate properties that generate verifiable cash flows.
In effect, proof-of-reserves brings crypto exchanges closer to the treasuries of decentralized finance protocols, where all funds are matched to cryptocurrency wallets that anyone can trace on-chain at any time. Additionally, DeFi products can be constructed around this data, allowing users to hedge against the fractional reserve activities of traditional off-chain institutions. A Merkle tree is a cryptographic tree in which every “leaf” (node) is labeled with the hash of a block of data.
Withdrawn auctions are counted as unsold properties when calculating the clearance rate. The family home at 13 Robinson Street was guided at $6 million, and eight parties registered to bid, though only three took part in the auction. So far the exchanges that have announced they will publish their PoRs are Binance, Bitfinex, Bitget, Bybit, Crypto.com, Deribit, Huobi, KuCoin, OKX, and Poloniex. In this article, we’ll look at how proof-of-reserves techniques aim to help, how they work, and some examples in action. An algorithm is a set of well-defined instructions used to perform calculations, accomplish a task, or solve a problem(s). The instructions must be executed in a specific order to produce the desired outcome.
Chainlink PoR feeds can be used to provide increased transparency for liquid staking derivative tokens, enabling anyone to verify whether liquid staking tokens are fully backed by staked native tokens. Swingby is using Chainlink PoR to help secure its cross-chain bridge and protect users by preventing wrapped tokens from being minted or swapped if the reserves backing them become undercollateralized. Secure Mint is being integrated by stablecoins, such as Poundtoken, and tokenized assets, such as Cache Gold, in their minting smart contract to help ensure reserves are sufficient before minting new tokens. Chainlink PoR Secure Mint enhances stablecoin and tokenized asset security by providing cryptographic guarantees that new tokens minted are backed by reserves, helping to prevent infinite mint attacks.
