What Are Validiums? š | Explained Simply
Validiums are a Layer 2 scaling solution designed to make blockchains faster and cheaper without sacrificing security. They work similarly to ZK-Rollups by using zero-knowledge proofs to validate transactions, but with one key difference š
š¹ Off-chain data storage
In validiums, transaction data is stored off-chain instead of on Ethereum. This massively reduces gas fees and boosts scalability.
š¹ High throughput & low cost
Because data isnāt posted on-chain, validiums can process a large number of transactions at very low costāperfect for gaming, NFTs, and high-volume apps.
š¹ Security via cryptography
Even though data is off-chain, transaction correctness is still guaranteed through ZK proofs, keeping the system trust-minimized.
š¹ Trade-off to note
The main compromise is data availability. Users rely on a data committee or operators to keep transaction data accessible.
š In short, validiums prioritize scalability and cost efficiency, making them ideal for applications that need speed and volume without fully relying on on-chain data storage.
Perfect example of how crypto keeps pushing the limits of scaling š”
