In depth
So what is PoR?
At its most basic, PoR is a concept in which custodians (a person or entity who has responsibility for or looks after something) need to be able to prove that they hold the assets that clients have entrusted to their care.
PoR enables the creation of a financial system where the fractional reserve practices and inefficient manual auditing processes that have contributed to financial crises in the past are replaced with highly effective on-chain audits with strong decentralization and transparency, secured by math and cryptography. [2]
Secure the minting, burning, and redeeming of wrapped tokens and prevent the creation of unbacked tokens
Replace traditional audits with automated, transparent audits backed by cryptographic truth
Allow users to independently verify wrapped token collateralization on-chain
Chainlink Proof of Reserve (PoR) enables DeFi projects to verify off-chain and cross-chain asset reserves through automated audits based on cryptographic truth.

https://chain.link/case-studies/celsius - Good quotes in this article. "As users and developers adopt more blockchains and layer-2 networks, liquidity becomes siloed across the ecosystem. Unlocking this fragmented liquidity through wrapped tokens and creating more interoperability is a critical challenge for the ecosystem to solve. Without a solution to this issue, the benefits of permissionless composability are reduced and developers need to start from scratch every time a new ecosystem is bootstrapped.
But how can projects make sure that wrapped tokens remain sufficiently collateralized when connectivity between different blockchains is inherently limited? While ensuring that wrapped tokens are collateralized at all times is critical for a robust cross-chain ecosystem, using centralized intermediaries and manual audits introduces efficiency bottlenecks and centralization risks.
An automated process is required that helps secure the minting and redemption of wrapped tokens and enables Celsius to securely, transparently, and reliably audit reserves so that users can move assets between blockchains and provide cross-chain liquidity."
