MTTBA- A Key Contributor for Sustainable Energy Consumption Time and Space Utility for Highly Secured Crypto Transactions in Blockchain Technology

A Merkle tree is an information construction that is used in Blockchain to verify data or transactions in a large content pool in a safe manner. The role of the Merkle tree is crucial in Bitcoin and other cryptocurrencies in a Blockchain network. In this paper, we propose a bright and enhanced verification method, Merkle Trim Tree-based Blockchain Authentication (MTTBA) for the hash node traversal to reach the Merkle Root in a minimum time. MTTBA is a unique mechanism for verifying the Merkle Tree's accumulated transactions specifically for an odd number of transactions. The future impact of cryptocurrency is going to be massive and MTTBA proves its efficacy in transaction speed and eliminating node duplication. Our method enables any block to validate transactions' full availability without duplicating hash nodes. Performance has been evaluated in different parameters and the results show marked improvement in throughput(1680ms), processing time(29700kbps), memory usage(140MB), and security(99.30%). The energy consumption factor is crucial in the scenario, and MTTBA has achieved the lowest of 240 joules.
