For many years of watching the development of blockchain, I have always viewed @Plasma as an idea that appeared very early and is foundational.
Plasma is designed to address Ethereum's scalability issue by moving a large number of transactions off the main chain, only keeping the necessary proofs on the mainnet.
Looking back, I see that Plasma is not just a technical solution, but also a way for the industry to start thinking seriously about separating transaction load and optimizing costs.
In the context of DeFi, Plasma was once expected to support high-frequency but low-value transactions.
Activities such as continuous token transfers, blockchain game transactions, or simple financial applications can operate on the Plasma chain at a much lower cost compared to Ethereum.
Despite the major limitation of not supporting complex smart contracts, Plasma still inspired later DeFi models on how to leverage the security of the original chain without having to handle everything directly on the mainnet.
