Plasma, a once-prominent Ethereum layer-2 scaling solution, should be revisited by teams currently working on zero-knowledge (ZK) Ethereum Virtual Machines (EVMs), said Ethereum co-founder Vitalik Buterin.
Invented in 2017, Plasma diverts data and computation — except deposits, withdrawals and Merkle roots — to an off-chain environment.
It was superseded by optimistic and ZK-rollups as the two solutions offered cheaper client-side data storage costs and security properties that “cannot be matched,” Buterin explained in a Nov. 14 X (Twitter) post.

Buterin said rollups remain the “gold standard,” but Plasma is an “underrated design space” that shouldn’t be forgotten.
“Plasma can be a significant security upgrade for chains that would otherwise be validiums,” Buterin added.
Like Plasma, validiums move data and computation off-chain but implement ZK-proofs to validate transactions. Plasma, on the other hand, uses fraud proofs, which are much slower.
Buterin argued improvements in ZK-proofs, such as validity proofs, address the past limitations of Plasma, making it more viable as a scaling solution.
Adapting Plasma for applications beyond payments has also proven to be an Achilles heel for Plasma before ZK-proofs entered the mainstream, Buterin acknowledged.
Buterin expects the Ethereum layer-2 ecosystem to evolve with diverse technological approaches.
