Proof of Reserves
A verification method showing that a custodian or exchange controls enough assets to back customer balances.
Why it matters
PoR matters because reserve transparency affects trust in exchanges, stablecoins, custodians, and tokenized assets, but incomplete PoR can create false confidence.
How it works
In practice, the institution identifies wallets or accounts, proves control over assets, publishes or shares a verification method, and ideally reconciles those assets against customer liabilities at a specific point in time.
Risks and pitfalls
The major pitfall is to read proof of reserves as proof of solvency. PoR may miss undisclosed liabilities, borrowed assets, timing manipulation, legal encumbrances, or weak custody governance.
Regional notes
In BIST/MOEX/global analysis, PoR should be framed as crypto-market transparency vocabulary and separated from statutory audit, bank capital adequacy, and regulated securities custody.
