Scaleswap Layer 2 Implementation

As of Spring 2021, the most logical way of building a layer 2 Ethereum solution for us was Polygon. We liked their solution-agnostic approach. Currently, we use Polygon’s Plasma PoS Bridge (ok ok, that’s still from the “Matic times,” to be exact). It’s a sidechain, which is basically “an independent EVM-compatible blockchain which runs in parallel to mainnet” [Joshua].

However, where are the guarantees that say, in 10 years, Plasma PoS won’t reach the “motherland’s” Ethereum scale with gas fees adjusting as well? There is none. Nevertheless, the economics of Polygon’s Plasma PoS [Mittal] limits the number of validator nodes, offering instead the increasing amount of transactions (and this is true as of May 2021). Therefore, instead of raising the transaction fees, validators are incentivized to keep the transaction growth trend.
