Vitalik published his latest article, in which he proposed using new technologies to transform Plasma.
Buterin stated in the article that Plasma has gone through many iterations since it was first proposed in 2017, and is now facing new developments. This technology allows all data and computation (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 was gradually replaced by rollups technology.
Now, the emergence of validity proofs (such as ZK-SNARKs) has caused Plasma technology to be reconsidered, especially in the payment field. This new Plasma chain will run EVM, and although security guarantees will not cover all users, in practice most assets will be safe. In addition, there are challenges in promoting Plasma technology into the fungible token space, such as handling complex EVM applications.
