Prom Explaining: zk-rollups vs Validiums
While explaining scaling solutions, zk-rollups and Validiums are often said to have similarities.
Explaining the differences and identical points.
đ What Are Validiums?
As a scaling solution, Validiums also utilize validity proofs to verify transactions off-chain, similar to zk-rollups, reducing the load on the main chain and leading to enhanced throughput.
đ Core Difference:
The main difference between the two solutions lies in data availability. Validiums store data off-chain, unlike zk-rollups, which store it on-chain.
đ Advantages & Risks:
Although off-chain DA reduces gas costs, zk-rollups provide better security, as Validiums rely on external DA providers holding a risk of compromising data integrity and a certain degree of centralization.
However, Validiums offer immense throughput, making the solution suitable for high-capacity applications.
