What is Proof of SQL? Proof of SQL is a cryptographic protocol that extends blockchain security to SQL databases. It enables smart contracts to query and verify large datasets in a trustless manner, significantly enhancing their capabilities. By outsourcing data processing to verified SQL databases, Proof of SQL effectively acts as a coprocessor for smart contracts, freeing them from the limitations of on-chain computations. How Does Proof of SQL Work? The Proof of SQL protocol leverages zero...
