Performance-Based Analysis of Blockchain Scalability Metric

Cryptocurrencies like Bitcoin and Ethereum, are widely known applications of blockchain technology, have drawn much attention largely recognized in recent years. Initially Ethereum processed 7 15 Transactions Per Second (TPS) respectively, whereas VISA Paypal process 1700 193 TPS respectively. The biggest challenge to adoption is scalability, defined as the capacity change block size handle growing amount load. This paper attempts present existing scalability solutions which broadly classified into three layers: Layer 0 focus on optimization propagation protocol for transactions blocks, 1 based consensus algorithms data structure, 2 aims decrease load primary chain by implementing outside chain. We a classification comparison performance along with their pros cons
