About zkRollup Many people consider zkRollup most important Ethereum Layer 2 scaling solution in the long term including Vitalik, the founder of Ethereum. Hear him; In general, my own view is that in the short term, optimistic rollups are likely to win out for general-purpose EVM computation and ZK rollups are likely…

Introduction Rolling up — ZKRollups and Optimistic Rollups — is the secret to fast, efficient crypto transactions. DeFi is developing at a breakneck pace. At the time of writing, DeFi’s TVL (Total Value Locked) was over $83 billion and continues to grow. Nonetheless, a significant impediment to DeFi is that most…

Blockchain Data Availability The latest Ethereum sharding roadmap [1] prioritizes data sharding over execution sharding, resulting in a significant increase in Ethereum data space throughput. Additionally, modular blockchains have delved into Rollup, volitions and validiums, and Data Availability Solutions. All these are just recent discussions and trends towards blockchain data availability. Anyone involved…

Layers of Blockchain Scalability is a critical requirement of the modern-day. If you’ve been involved in any way with cryptocurrency or blockchain technology, you’ve probably heard of “layer-1” and “layer-2” solutions. The Blockchain Trilemma, a balancing act between decentralization, security, and scalability in blockchain infrastructure, is a unique problem that…

Introduction One factor contributing to the complexity of cryptocurrency trading is the sheer number of blockchains and exchanges involved. For instance, if a user wishes to transfer 2 ETH that exists on the Ethereum blockchain (ERC-20) to the Avalanche network, the user may be required to pass through many processes and…

Introduction Blockchain technology is prevalent in both traditional and crypto industries, including NFTs, DeFi, GameFi, supply chain consortiums, and the metaverse. Due to the diversity of use cases and application scenarios, various types of blockchain have evolved (permissionless, permissioned, and private). The contentious issue is, in essence, self-evident: “blockchain interoperability.” Interoperability…
