  • One article to understand why Web3 projects need to be automated in a decentralized manner

    The blockchain ecology has developed from a simple on-chain token to a series of advanced decentralized applications, and the underlying technology of these applications is hybrid smart contracts. However, there is a key problem with smart contracts, that is: the blockchain adopts a closed-loop architecture to ensure security. Because of this, smart contracts on the chain cannot be automatically executed. That is, contracts cannot run automatically based on predefined conditions, such as executing contract functions when the token reaches a certain price, the loan collateralization ratio falls below a certain threshold, or…

  • One article to understand NFT (non-fungible token)

    definition The full name of NFT is non-fungible token, which is a digital token on the blockchain. Each token has a unique subject matter, such as digital artwork, special game items, rare card collections or any other unique digital/physical assets. NFT is the latest emerging blockchain asset, which goes beyond the scope of cryptocurrency, stablecoin, governance token and utility token, provides users with brand-new digital assets, and innovates the ownership and issuance model. ‍ This article will explore the definition of NFTs, the rapid development of the NFT collectible economy,…

  • Summary of the use of price oracles (2): UniswapV2

    foreword The previous article in this series introduced the use of the Chainlink price oracle, which is currently used by most DeFi applications, but still has limitations. First of all, the coverage of the supported tokens is not complete, especially long-tail assets, most of which are not yet supported, such as SHIB . Currently, only the BSC mainnet has the SHIB / USD Price Feed , while other networks have not, even Ethereum. are not supported yet. Secondly, the deviation threshold of some assets is relatively large, and the price update is relatively slow, and it may take up to ten or…

  • Messari: Detailed explanation of Mina’s technical features, operation mechanism and economic model

    Traditional blockchains are inefficient at storing ever-growing amounts of data. This state bloat problem can negatively impact the decentralization of the network, as fewer users are able to participate in chain verification. The Mina protocol is a new generation of layer1 blockchain that solves the problem of state inflation. With the power of zk-SNARKs, Mina maintains a fixed small size of about 11 kB. In addition to decentralization, zk-SNARKs also make Mina more private and efficient than other chains. Other new-generation blockchains have been optimized for scalability in the blockchain trilemma, affecting decentralization…

    Will quantum computing disrupt blockchain or make it more secure? When it comes to the future of computing, blockchain and quantum computing are two of the most fascinating and controversial industries. While blockchain is far more advanced in its practical applications — including the creation of cryptocurrencies and cryptography that both individuals and businesses can use — the quantum computing industry is also growing at an alarming rate. In fact, the industry growth rate of quantum computing may be second only to blockchain, with the industry expected to grow at an annual…

  • Composability of Web3 Data Networks

    A few months ago, at the 2021 Multicoin Summit, I gave a keynote that highlighted composability as the most important development in the cryptocurrency space for mid-2022. While that presentation focused on the composability of financial assets on the Solana chain, financial composability is not the only form of composability. There’s an even bigger opportunity for composability: data composability. Layer 1 networks are the underlying architecture of the cryptocurrency ecosystem. These networks are loosely referred to as Layer 1 (L1) because they all have a set of independent nodes reaching consensus with some…

  • Why Cairo may replace Solidity

    In this post, I will argue that Cairo can influence the coming wave of provable computing in the same way that Solidity supports composable computing. Cairo is the native programming language for StarkNet, an L2 network for scaling Ethereum. It is unfortunate when we think of smart contracts as merely an extension of finance (DeFi) or a generalization of the web (web3). Smart contract networks are actually platforms for composable computing. Ethereum embeds some standards that allow its computer programs to interoperate: Transparent bytecode (no hidden web API) Standardized API structure (called…
