Understanding Ethereum’s “Proof of Reserves” and “Proof of Liabilities” – A Beginner’s Guide
As the second-largest cryptocurrency by market cap, Ethereum is a complex and fascinating space. Two key concepts that are often discussed in the context of Ethereum are “proof of reserves” (PoR) and “proof of liabilities” (PoL). While these terms may seem unfamiliar to newcomers, understanding what they mean can help you understand the inner workings of the Ethereum network.
What is a short way to describe what proof of reserves and proof of liabilities mean?
In simple terms, proof of reserves refers to a mechanism that ensures that a certain amount of Ether (ETH), the native cryptocurrency of the Ethereum network, exists on the blockchain. This is done by verifying that a specific amount of ETH has been “stored” or “reserved” in a specific wallet or account. In essence, it’s like having an insurance policy for your Ethereum holdings.
On the other hand, proof of responsibility refers to a mechanism that ensures that a certain amount of Ether exists on the blockchain if it hasn’t already. This is typically done by verifying that a specific amount of ETH has been “lent” or “owed” to another entity or wallet. In this case, it’s like having a backup plan for your Ethereum holdings.
What are their differences?
The main difference between proof of reserves and proof of responsibility lies in the purpose they serve:
- Proof of Reserves (PoR)
: This mechanism is used to ensure that a certain amount of ETH exists on the blockchain. It’s like having an insurance policy for your Ethereum holdings.
- Proof of Responsibility (PoL): This mechanism is used to ensure that a certain amount of ETH is available if it hasn’t already been. It’s like having a backup plan for your Ethereum holdings.
Is it performed by an auditor?
The auditing process is crucial to ensure the integrity of the Ethereum network and verify whether the PoR or PoL mechanisms are working properly. Auditors, often independent third-party companies, verify that the Ethereum blockchain meets certain standards and requirements before granting permission for a new smart contract to be deployed.
Is it performed manually or automatically?
PoR is usually implemented manually by validators who verify the existence of ETH on the blockchain using complex mathematical algorithms. In contrast, PoL is often implemented automatically through a system called “liquidations,” which ensures that a certain amount of ETH exists in case of an emergency (for example, if there is a high demand).
In short, proof-of-reserves and proof-of-liabilities are two distinct mechanisms used to ensure the integrity of the Ethereum network. While PoR is used to verify the existence of ETH on the blockchain, PoL is used to ensure its availability in case of an emergency. Understanding these concepts can help you better understand the inner workings of the Ethereum network and make informed decisions about your investments.
