What is T+N (Security protection for buying crypto)? T+N refers to a security protection mechanism for cryptocurrency purchases. When you buy crypto through P2P on the platform, the system performs a comprehensive risk assessment of the transaction. Based on this assessment, it may temporarily restrict the withdrawal and P2P resale of the equivalent assets for N days.

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.

Some tokens may have T+N security protection, meaning they cannot be withdrawn or sold within N days after purchase to ensure account security. The exact number of days is shown on the platform. For more details, please refer to: What should I do if the T+N security protection is triggered and I can't trade? 11. Is it allowed to buy tokens through P2P trading using another person's bank account/payment method?

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).
