What Are Rollups?
Rollups bundle hundreds of transactions off-chain and submit a compressed proof to the main chain. Think of it as packing a thousand letters into one envelope. The result: dramatically lower costs and higher throughput without sacrificing security.
TYPE: Layer 2 ScalingZK-Rollups
Zero-knowledge rollups use cryptographic validity proofs. Every batch submitted includes a mathematical proof that all transactions are valid. No trust required — only math. The gold standard of rollup security.
PROOF: Validity (ZK-SNARK / ZK-STARK)Optimistic Rollups
Optimistic rollups assume transactions are valid by default and only compute proofs when challenged. A dispute period allows anyone to submit a fraud proof. Faster to implement, with the trade-off of a withdrawal delay.
PROOF: Fraud (Challenge Period)The Scalability Quest
The quest continues. Rollups are not the final answer but the current frontier. Each breakthrough in proof compression, data availability, and interoperability brings us closer to a blockchain that can serve everyone.
