Odaily News In his reply to netizens on the X platform, Vitalik said that the focus of Plasma is not to prevent invalid/unusable state transitions, but to allow users with valuable assets to use the previous (valid and usable) state to exit when this happens, in a way that has self-consistent rules to prevent double exits of any assets. Last November, Vitalik published his latest article, in which he proposed to transform Plasma with new technologies. In the article, V God said that Plasma has undergone many iterations since it was first proposed in 2017, and is now facing new developments. This technology allows all data and calculations (except deposits, withdrawals, and Merkle roots) to remain off-chain, greatly improving scalability. However, due to the high cost of client data storage and the inability to be generally applicable to applications other than payment, Plasma has gradually been replaced by rollups technology. Now, the emergence of validity proofs (such as ZK-SNARKs) has allowed Plasma technology to be reconsidered, especially in the field of payment. This new Plasma chain will run EVM, and although the security guarantee will not cover all users, it can still ensure the security of most assets in practice. In addition, there are challenges in extending Plasma technology to the field of fungible tokens, such as dealing with complex EVM applications.
