Till now, proposals to enhance blockchain scalability have addressed the issue in one in every of two methods. One seeks to extend effectivity by optimizing the blockchain or enhancing the consensus algorithm. The opposite comes within the types of layer-2 options equivalent to cost channels or facet chains.
Nonetheless, none have addressed the core bottleneck to scalability: TCP/IP community limitations. Enhancing the pace at which blocks propagate via the community is the layer-Zero downside few individuals think about when serious about scaling.
Essentially, community bottlenecks are what forestall blockchains from growing their transaction throughput.
