#plasma $XPL Plasma is the pioneer in Ethereum scaling, creating a "blockchain within a blockchain" with a sidechain structure. The main chain anchors security, while the subchain handles high-frequency transactions, alleviating congestion pressure. User assets can quickly enter and exit, balancing efficiency and security. Although it faced challenges such as exit delays in its early days, it remains a classic Layer 2 solution, paving the way for high-concurrency scenarios (such as DeFi, NFT). @Plasma
