What Are Validiums? 🚀 | 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 👇
🔹 Off-chain data storage
In validiums, transaction data is stored off-chain instead of on Ethereum. This massively reduces gas fees and boosts scalability.
🔹 High throughput & low cost
Because data isn’t posted on-chain, validiums can process a large number of transactions at very low cost—perfect for gaming, NFTs, and high-volume apps.
🔹 Security via cryptography
Even though data is off-chain, transaction correctness is still guaranteed through ZK proofs, keeping the system trust-minimized.
🔹 Trade-off to note
The main compromise is data availability. Users rely on a data committee or operators to keep transaction data accessible.
👉 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 💡
