Vitalik Buterin, the co-founder of Ethereum (ETH), has ignited a debate concerning the classification of varied layer 2 scaling options.
The crypto veteran has claimed that Ethereum’s validiums shouldn’t be thought of real rollup options.
The assertion got here in response to a post by Daniel Wang, the founding father of Taiko, an Ethereum rollup resolution, who stated if an Ethereum rollup depends on an exterior knowledge chain, comparable to Celestia’s modular blockchain, then it ought to be categorised as a validium.
Buterin concurred with Wang’s remark, stating:
“That is right. The core of being a rollup is the unconditional safety assure: you will get your belongings out even when everybody else colludes towards you.”
He emphasised that if knowledge availability will depend on an exterior system, that safety assure can’t be upheld.
That is right.
The core of being a rollup is the unconditional safety assure: you will get your belongings out even when everybody else colludes towards you. Cannot get that if DA depends on an exterior system.
However being a validium is an accurate alternative for a lot of apps, and…

What’s Validium?
Validium is a scaling resolution for Ethereum that makes use of zero-knowledge proofs to allow off-chain transactions, whereas nonetheless counting on the Ethereum mainnet for safety and verification.
Not like ZK-rollups, which batch transactions on a layer 2 community and confirm them on a layer 1 like Ethereum, validium networks don’t submit transaction knowledge to layer 1.
As an alternative, they submit cryptographic proofs of transaction validity, aiming to attain greater scalability by avoiding the necessity to retailer full transaction knowledge on-chain.
Nonetheless, in comparison with rollups, validiums face challenges by way of knowledge availability, as they depend on operators to truthfully submit proofs.
Networks like Celestia make use of modular blockchains consisting of knowledge availability layers and validation layers, with validiums facilitating quick and personal transactions.
Buterin took to the decentralized social media platform Warpcast to share a diagram proposing changes to terminologies associated to those scaling options.
He instructed changing phrases like “security-favoring” and “scale-favoring” with “sturdy” and “gentle” to attain higher brevity.
Some Argue Validiums Ought to Be Thought-about L2 Networks
Whereas Buterin’s proposals garnered help, not everybody agreed.
Ryan Berckmans, a member of the Ethereum group, argued that validiums ought to be thought of layer 2 networks.
“A layer-2 is a series that settles on Ethereum. I’ll die on this hill, and I’ll debate anybody who insists the [data availability] must be on Ethereum for it to be an L2,” he stated.
Berckmans believed that the definition of layer 2 ought to embody each rollups and validiums.
Nonetheless, a layer 2 trade analytics platform known as L2Beat contradicted Berckmans’ perspective, asserting that validiums usually are not layer 2 options.
In line with L2Beat, validiums and optimiums introduce extra belief assumptions by not publishing knowledge on layer 1.
As reported, Ethereum-based layer 2 community Arbitrum now has a market share of 49.17% amongst layer 2 networks, far surpassing quantity two on the checklist, Optimism Mainnet, with its 28.85% market share.
The community has additionally seen a consistent increase in its TVL at the least since October final 12 months, rising about 50% from $1.66 billion in October to the present worth of $2.51 billion, knowledge from DeFi monitoring web site DefiLlama confirmed.
The upcoming Ethereum Dencun upgrade, incorporating modifications proposed by EIP-4844, is anticipated to cut back rollup transaction prices, benefiting layer 2 options like Arbitrum by decreasing gasoline charges and enhancing community capability.
