Deposit locked due to P2P T+N risk control being triggered When you're buying crypto through P2P trading, our risk control system will comprehensively assess your transaction risks and impose N-day restrictions on the withdrawal and P2P sales of the equivalent amount of assets in your transaction. It's recommended that you wait patiently for N days and the system will automatically lift the restriction.2.

Low-degree polynomial extension: using the above polynomial constraints, we can obtain a computation trace polynomial of length uts * N. For security reasons, we perform commitment to the polynomial on a larger evaluation domain, with the domain amplification factor as extension_factor. In the above case, we could calculate a polynomial p(x) from I(x). When we use an extension_factor of 8, we will calculate another 32(8-1)* points on p(x).
