The return of Plasma is not nostalgia, but a re-examination of Rollup.
If you calm down and examine the current Layer 2 landscape, you will find a somewhat ironic phenomenon. On the surface, everything looks glamorous: top VCs on stage, valuations in the billions, and exquisite brand narratives. But has the actual user experience truly undergone a qualitative change?
For ordinary users, reality is not so ideal. Gas fees are advertised as 'low', but once the network is congested, costs immediately surge. Meanwhile, project teams continue to introduce various 'point tasks', 'interaction activities', and 'incentive programs', which seem to be full of benefits but actually repeatedly harvest attention and liquidity. Over time, this feels more like a carefully packaged performance rather than a genuine technological advancement.
So when Vitalik mentions Plasma again, it is not simply about resurrecting an old technology, but more like reopening a door that was closed too early. Plasma is not just a scaling solution; it is actually challenging the current L2 interest structure and economic logic.
The reason Plasma went silent back then was largely due to its high demands on users. The exit mechanism is complex, requiring continuous monitoring of on-chain status, and any negligence could lead to risks. This uncertainty caused the market to gradually lose confidence, and the narrative shifted to Rollup.
But today's technological environment is different.
The maturity of zero-knowledge proofs (ZK) has changed many premises. The 'security exit anxiety' that plagued Plasma in the past can now be alleviated through cryptographic guarantees. Users no longer need to constantly monitor the market; each transaction can be verified for its legitimacy to the main chain through ZK proofs. Even if there are issues with the side chain, assets can safely exit within the rules framework.
This is precisely where rethinking is needed.
The core security of Rollup is built on submitting compressed data to Ethereum. While this provides strong security guarantees, it also means that costs always have a 'floor price'. No matter how much optimization is done, as long as there is reliance on the main chain's data availability, fees will never truly reach zero.
