Seeing many people discussing Plasma, this new public chain, I will summarize my understanding.

In simple terms, Ethereum and Plasma are on two completely different paths.

Ethereum's ambition is very large — to become an all-encompassing "world computer." It aims to support DeFi, NFTs, DAOs, gaming, social applications, and more. This versatility is a strength, but it also means everything must be compatible and considered.

Plasma, on the other hand, is very restrained. Its goal is singular: to create the strongest solution for stablecoin payments and financial settlements. Focused specialization becomes an advantage — ultimate efficiency, lower costs, and better user experience. You can think of it as a high-speed highway dedicated to financial applications, while Ethereum is a broad avenue where all kinds of vehicles can run.

But this doesn't mean Plasma has any flaws; quite the opposite.

Plasma cleverly inherits Ethereum's mature ecosystem entirely. First, it is fully compatible with EVM — supporting Solidity and Vyper, so smart contracts on Ethereum can be migrated directly and run without re-learning languages or rewriting code. Second, the wallet ecosystem remains consistent; tools like MetaMask and WalletConnect can be used directly, reducing migration costs.

This design approach is quite smart. It leverages over a decade of Ethereum's technical accumulation while excelling in the niche of stablecoins. For developers and users, the onboarding process is almost zero difficulty, yet the improvements in performance and cost are tangible.
