Blockchain is a data structure made up of chronologically ordered data blocks. Research revealed that traditional blockchains have constrained throughput. It is ideal for blockchain technology to achieve higher throughput by increasing the block size and lessening the block interval. The methodology used in this paper is of two parts. The first approach uses the cryptographic protocol to ensure the authenticity and integrity of the information using an Ethereum blockchain type. This means that transactions are recorded in write-only mode and contributes to transaction trust and transparency. Our methodology automates smart and secure evaluations and provides credentials using an Improved Elliptic Curve Cryptography Algorithm (IECCA). It is implemented using encryption and decryption algorithms and is demonstrated using analytical and content neutrality. We also demonstrate operation from back-end to end-users application including student and faculty members. The Level of security performance of the proposed scheme is compared with another scheme for a 20MB file size. The proposed schemes achieve 83% IECCA, 78 percent DES, 76% RSA, and 70% AES respectively. The second approach identifies the boundary for conventional block sizes and block intervals. Security of blockchain using stale block rate is identified in the network by conducting a realistic experiment. This enables the realization of optimal block parameters like size and interval. Results presents achieve a rate of transmission for a blockchain platform to be deployed in other activities beyond cryptocurrency, like electronic voting.
