The increasing popularity of crypto and blockchain has led to developers seeking a way to scale by improving a system’s ability to accommodate the growing demand. Sharding, sidechains, state channels, and rollups are some approaches to scaling. Blockchain rollups offload certain transaction processes to a secondary chain while storing transaction data on the main Layer 1 blockchain. In this article, we explore the two types of rollups in the crypto space &nd ... 阅读全文

The use of such solutions allows developers greater flexibility in designing ecosystems, governance structures, and consensus algorithms for the decentralized applications they create. How do appchains work? Appchains operate in a similar manner to a basic blockchain, but on top of it. The primary distinction is that they are app-specific. Appchains rely on Layer 1 (L1) blockchains in terms of security. Because they do not compete for processing power and storage ... 阅读全文

The approach taken by regulators fails to acknowledge the unique qualities of cryptocurrencies and the benefits they can provide, and instead seeks to impose traditional financial rules on a technology that cannot simply be forced into the same category. New waves of cryptocurrency regulation are usually brought about following some form of incident within the cryptocurrency market. Regulators are therefore reactive to the various irregular events that happen in c ... 阅读全文

Wrapped tokens that feature assets to be used behind the native blockchain or original design are gaining widespread application across DeFi platforms. A wrapped token is an asset representing the value of a blockchain’s native asset on another blockchain. A wrapped token’s value is pegged 1:1 to an underlying asset meaning that, for instance, the price of one wETH (wrapped ETH) should be one ETH. How do wrapped tokens work? Wrapping involves locking ... 阅读全文

Web3 is a collection of libraries that allow developers to interact with decentralized applications (dApps) and the Ethereum blockchain. Web3 use cases allow businesses to take advantage of a robust and decentralized system of technologies, such as blockchain, cryptography, NFTs, and DeFi. What are the Security Challenges in the Web3 Era? The lack of security in Web 3 can have a significant impact on users. Without proper security measures, users are vulnerable to ... 阅读全文

Open Zeppelin’s ERC-20 reference implementation is widely used in Web3. A bug in it would be devastating for the many contracts that derive from it. But how do we know that it is correct? And how do we know contracts that derive from it do so correctly and do not introduce bugs? In Part One of this series on formal verification, we explained how CertiK uses formal verification to mathematically prove the correctness of ERC-20 contracts that we audit. Let’s dive ... 阅读全文

Permissionless blockchains are open to anyone to use. You can even participate in their consensus mechanisms, given that you meet specific requirements. Bitcoin, Ethereum, and BNB Chain are all examples of permissionless blockchains, which are typically transparent and decentralized. Permissioned blockchains, on the other hand, require invitations to join. They’re typically used in private business settings and tailored for certain use cases. Power is restricted ... 阅读全文

A decentralized exchange (DEX) is a type of cryptocurrency exchange that operates in a decentralized manner, meaning it does not rely on a central authority or server to function.
