What Are the Security Risks Associated with Private Computation on a Blockchain?
Key risks include potential bugs in the complex cryptographic proofs (ZKPs), which could allow a malicious actor to generate invalid proofs and commit fraud. Additionally, if the trusted setup for a zk-SNARK is compromised, it could undermine the entire system.
There is also the risk of front-running if the inputs are revealed just before the transaction is executed, even with privacy layers.
Glossar
Private Computation
Execution ⎊ Private Computation refers to the execution of algorithms or smart contract logic in an environment where the inputs and the resulting output are shielded from the network validators or the public ledger itself.
Private Computation Layer
Definition ⎊ A private computation layer refers to a blockchain or off-chain network specifically designed to execute smart contracts and process transactions while maintaining the confidentiality of the data involved.
