Proof of Reserves – The Current State ofCryptocurrency Security

Proofs of Reserves are a way for cryptocurrency exchanges to prove that their funds are safe and secure. The main objective of PoR are as follows, 

• Transparency on the availability and support of funds for customers. 
• Enable customers to independently and cryptographically confirm that their account balances are included in the PoR to increase trust.

What Is Proof of Reserves (PoR)?

• Proof of Reserves (PoR) is a scheme that aims to provide transparency and accountability in the cryptocurrency world. PoR is a protocol that relies on the use of cryptographic proofs to show that a certain amount of cryptocurrency is held by an address. 
• More precisely, Proof of Reserves (PoR) is a means to confirm that a company (like a cryptocurrency exchange) has enough reserves to back all of its customers’ balances. Digital assets that can be validated via on-chain techniques, such as tracking wallets, are referred to as PoR. Off-chain assets like cash reserves and other fiat assets are excluded.
• The idea behind PoR is to provide an independent and trusted third party with the capability to verify whether or not a user has enough funds for transactions. This system will create more trust between the users and exchanges, as it will be possible for users to know if their funds are being stored securely by exchanges.
• Digital assets that can be validated via on-chain techniques, such as tracking wallets, are referred to as PoR. Off-chain assets like cash reserves and other fiat assets are excluded.

Why a Proof is Needed for a Blockchain Network?

• A proof is needed for a blockchain network in order to prove that the data is not altered. The data must be verified by a group of people known as miners.
• Proofs are mainly used to validate transactions and blocks in a blockchain network. It is an algorithm that takes input and calculates output. Proofs are used to verify transactions and blocks on the blockchain network. 
• Proofs can also be calculated for verifying data on the blockchain network, as it is easy to alter information on the internet without leaving any trace of evidence, which makes it hard to verify whether or not the information has been changed or not.

What is Proof of Reserve and How Does it Work?

• Proof of reserve is a process that ensures that the cryptocurrency, or any other digital asset, is in the possession of the company and can be used for withdrawal.
• The term “proof of reserves” refers to an independent audit that centralised exchanges can use to publicly attest to the value of their reserves and demonstrate their solvency. This audit is known as “proof of reserves” in the blockchain community.
• Proof of reserve is a process that ensures that the cryptocurrency or any other digital asset is in the possession of the company and can be used for withdrawal. The process includes a company submitting a cryptographic hash to nodes on their network. The nodes then verify that they have access to all of the coins specified by this cryptographic hash.

Proof of Reserves (PoR) and the Importance of Transparency in Crypto Security

• Following FTX’s demise, which became insolvent by utilising customer funds to close balance sheet gaps for its trading arm, Alameda Research, reserves became more widely used. In response to the demand for public attestations of their reserves, other centralized exchanges have published or pledged to disclose proof of reserves.
• Proof of reserves should, in theory, reassure clients of a custodian’s stability and boost trust in their operation. However, in reality, proof of reserves may be falsified, altered, or simply not provide the whole story.
• Additionally, the PoR makes no mention of off-chain assets or liabilities. Additional assets may be held by a custodian off-chain or in secret wallets. Therefore, to ensure accurate information in a PoR testament, a thorough audit would be required. It can be viewed as an effort at user confidence and self-regulation in the face of user mistrust over custodial crypto firms’ business activities.
  In summary, Proofs of Reserves can be used to show your customers that you have enough money in your bank account to cover all withdrawals. 

Why Do We Need Reserve Proof?

PoR is beneficial for a number of reasons:

• A PoR attestation conveys caution on the financial stability of an exchange. It boosts user trust in a custodian and attests to the level of transparency the custodian promises.
• PoR is a technique for self-control. Although certain exchanges are not subject to US regulation, PoR may lead to more favourable treatment by US regulators and increased user confidence.
• PoR makes it harder to cover up unethical and unlawful company actions, such as rehypothecating user deposits.

Nevertheless PoR is not completely unreliable. It depends on voluntary participation and cannot ensure complete disclosure of a custodian’s financial condition. However, given the industry’s dismal track record of consumer fund transparency, many view it as a first step toward establishing a minimal level of self-regulation. Additionally, exchangers and lenders are free and encouraged to look for additional regulation to improve their standing in the industry and win the trust of their clients.

How is a PoR carried out?

PoR entails the following steps:

1. Confirming that the audited company is the legal owner of the assets they represent their clients as having control over.
2. Comparing the assets held by the audited company to the precise amount of the total assets of the customers as determined by their combined account balances for each of the audited assets
3. Putting together a verification tool that will let each client to independently confirm that their account balances were in fact included in the PoR. 

Conclusion

Proof of reserves is a cryptocurrency auditing process that is meant to demonstrate that a cryptocurrency exchange has sufficient funds in reserve to honor all existing customer balances. If a cryptocurrency exchange does not have sufficient material funds in their cold storage, then it can be said publicly and transparently by anyone.
