“…This is an intuitive application of Web3 as all the assets held by users are stored in their wallets. Performing financial-related activities, such as swap-ping different tokens at DEXes, loaning coins from exchanges, buying/selling crypto-assets from fiat to stablecoins, and designing derivatives (e.g., NFT [12], contracts, securities [60], share, etc. ), becomes common and easier for single users since they do not need to register to any financial intermediaries.…”

Web3 is the most hyped concept from 2020 to date, greatly motivating the prosperity of the Internet of Value and Metaverse. However, no solid evidence stipulates the exact definition, criterion, or standard in the sense of such a buzzword. To fill the gap, we aim to clarify the term in this work. We narrow down the connotation of Web3 by separating it from high-level controversy argues and, instead, focusing on its protocol, architecture, and evaluation from the perspective of blockchain fields. Specifically, we have identified all potential architectural design types and evaluated each of them by employing the scenario-based architecture evaluation method. The evaluation shows that existing applications are neither secure nor adoptable as claimed. Meanwhile, we also discuss opportunities and challenges surrounding the Web3 space and answer several prevailing questions from communities. A primary result is that Web3 still relies on traditional internet infrastructure, not as independent as advocated. This report, as of June 2022, provides the first strict research on Web3 in the view of blockchain. We hope that this work would provide a guide for the development of future Web3 services.

It is shown in recent studies that in a Stackelberg game the follower can manipulate the leader by deviating from their true best-response behavior. Such manipulations are computationally tractable and can be highly bene cial for the follower. Meanwhile, they may result in signicant payo losses for the leader, sometimes completely defeating their rst-mover advantage. A warning to commitment optimizers, the risk these ndings indicate appears to be alleviated to some extent by a strict information advantage the manipulations rely on.at is, the follower knows the full information about both players' payo s whereas the leader only knows their own payo s. In this paper, we study the manipulation problem with this information advantage relaxed. We consider the scenario where the follower is not given any information about the leader's payo s to begin with but has to learn to manipulate by interacting with the leader. e follower can gather necessary information by querying the leader's optimal commitments against contrived best-response behaviors. Our results indicate that the information advantage is not entirely indispensable to the follower's manipulations: the follower can learn the optimal way to manipulate in polynomial time with polynomially many queries of the leader's optimal commitment.

“…File storage is a fundamental issue in distributed systems. Recently, the developments of Web 3.0 [1], Non-Fungible Tokens (NFTs) [9,22], and Metaverse [20] have raised high requirements on reliability and accessibility of file storage. For example, the metadata of NFTs should be verifiable and accessible in NFT markets, as the values of NFTs disappear if the metadata is lost.…”

With the development of blockchain applications, the requirements for file storage in blockchain are increasing rapidly. Many protocols, including Filecoin, Arweave, and Sia, have been proposed to provide scalable decentralized file storage for blockchain applications. However, the reliability is not well promised by existing protocols. Inspired by the idea of insurance, we innovatively propose a decentralized file storage protocol in blockchain, named as FileInsurer, to achieve both scalability and reliability. While ensuring scalability by distributed storage, FileInsurer guarantees reliability by enhancing robustness and fully compensating for the file loss. Specifically, under mild conditions, we prove that no more than 0.1% value of all files should be compensated even if half of the storage collapses. Therefore, only a relatively small deposit needs to be pledged by storage providers to cover the potential file loss. Because of lower burdens of deposit, storage providers have more incentives to participate in the storage network. FileInsurer can run in the top layer of the InterPlanetary File System (IPFS), and thus it can be directly applied in Web 3.0, Non-Fungible Tokens, and Metaverse.
