…The Development of ZK Rollups Zero-Knowledge rollups (ZK rollups) are still at a nascent stage. However, as the technology evolves, various methods have emerged to achieve compatibility with the Ethereum Virtual Machine (EVM).

Learn More…ZK rollups bundle multiple transactions off-chain, compute their results, and then submit a single compressed proof (ZK-SNARK) to the mainchain, which verifies the correctness of the off-chain computations without needing to process each transaction individually or reveal the actual data being computed.Key TakeawayA Zero-Knowledge (ZK) rollup is a Layer-2 scaling solution for blockchains, particularly designed to improve scalability and reduce transaction costs.Related WordsSolana Program Librar…
Learn More…This contributes to more scalable Layer-2 solutions (like ZK rollups), where thousands of transactions can be verified with a single proof. Real-World Use Cases: Confidential DeFi protocolsPrivacy-preserving voting systemsIdentity proof without data exposure (great for Web3 logins and KYC) A Note on Current Limitations: Resource intensive: Generating and verifying ZK proofs can be computationally demanding. Developer complexity: Integrating ZK proofs requires advanced cryptographic knowledge. St…

Key Takeaways: The most popular types of Layer-2s on Ethereum are optimistic rollups and Zero-Knowledge rollups (ZK rollups). However, there are also other Layer-2 technologies like sidechains, plasma chains, and validiums.In general, optimistic rol…

Learn More…Unlike Optimistic and ZK rollups in the Ethereum network, sovereign rollups do not utilise a settlement layer or require smart contracts. They manage their own execution and settlement, and only use the underlying Layer-1 blockchain for consensus and data availability (unlike other rollup types that rely on the blockchain to determine a rollup’s validity). In general, rollups on Bitcoin are experimental and still in their infancy; much remains to be seen in terms of applying rollups to Bitco…
