Speaking of public chain technology, there's an unavoidable challenge—the so-called "trilemma" of scalability. Want a chain that simultaneously ensures security, decentralization, and high throughput? It's basically a false proposition; you can at most choose two out of three.

Ethereum, as an established mainnet, prioritizes security and decentralization. The cost? Whenever the market is bullish and transaction volume skyrockets, Gas fees shoot up like rockets, and confirmation speeds become ridiculously slow, sometimes taking half a day to complete a transaction. User experience suffers directly.

However, the emergence of Layer 2 network technology has changed this game. Among them, Plasma solutions were proposed early on, but recently many have re-evaluated them. Let's discuss the logic behind it.

The idea of Plasma is very simple—use side chains to divert pressure from the mainnet. Most transactions are processed on the side chains, so the mainnet doesn't bear such a heavy load. In the end, the side chains only need to bundle and submit transaction results back to the mainnet for final settlement.

The benefits of this design are obvious: transaction speeds increase, and the mainnet's security and decentralization are preserved. It's like giving the mainnet some enforcers—offloading heavy work onto them, while the mainnet only needs to ensure the final quality.

The specific workflow is as follows—Plasma will build a set of distributed side chain networks, each capable of independently processing transactions without relying on real-time synchronization with the mainnet. Periodically, the side chains will summarize transaction hashes (proofs) and submit them to the mainnet for accounting and final confirmation.
