Plasma, a once-prominent Ethereum layer 2 scaling solution, should be revisited by teams currently working on zero-knowledge Ethereum Virtual Machines (EVMs), says 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It was superseded by optimistic and zero-knowledge (ZK)-rollups as the two solutions offered cheaper client-side data storage costs and security properties that “cannot be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.
“The fact that ZK-EVMs are finally coming to fruition this year makes it an excellent opportunity to re-explore this design space, and come up with even more effective constructions to simplify the developer experience and protect users’ funds.”
Like Plasma, validums 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.
Babe wake up Vitalik just revived Plasma

Minimal Viable Plasma, Plasma Cash and Plasma Cashflow are among the iterations that have stemmed from Plasma.
Ethereum layer 2 scaling-focused firm Polygon Labs implemented Plasma in 2019 but has implemented several other solutions since.
The movement away from Plasma was partially attributed to Plasma Group, a nonprofit research firm announcing that they would cease working on Ethereum-based scalability in January 2020.
OMG, the token of OMG Network — which uses Plasma — spiked 28.6% to $0.78 in a three-hour window following Buterin’s post, according to CoinGecko. However, it has since fallen 14.3% to $0.67.
