    Known for its decentralisation, transparency and security, blockchain technology is transforming a range of sectors, starting with finance and now extending to IoT, eCash and healthcare. However, the open nature of blockchain raises potential security concerns around sensitive transaction data, and the increasing number of transactions requires low latency solutions. Most blockchain applications still rely on the lightweight elliptic curve digital signature algorithm (ECDSA), which can introduce significant overhead due to complex operations such as scalar multiplication and modular inversion.To address these issues, a new scheme called KTP-ECDSA, based on an improved two-parameter elliptic curve digital signature (TP-ECDSA) and the KGLP algorithm, has been proposed. This scheme eliminates modular inversion in both the signing and verification processes, and uses batch verification to reduce scalar multiplications during verification. Experimental results show that KTP-ECDSA achieves more than a 50% speedup over traditional ECDSA for both independent and batch verification, significantly improving the efficiency of signature verification.
