Validity Proofs
Validity proofs are the mathematical evidence used in ZK Rollups to verify the correctness of a state transition without re-executing the underlying transactions. These proofs, often implemented as SNARKs or STARKs, compress large amounts of data into a small, easily verifiable string.
They ensure that the rules of the protocol have been followed, such as checking signatures and account balances. In the context of derivatives, validity proofs ensure that every trade, liquidation, and settlement is mathematically sound.
This removes the need for users to trust a central exchange operator. Instead, they trust the underlying mathematics and the code of the smart contract.
This trustless verification is the backbone of secure scaling solutions. It enables high-frequency trading platforms to operate with the same security guarantees as the main blockchain.
