“…Internet TheOoL.net (Nenashev & Khryashchev, 2019;Nenashev et al, 2021;TheOoL White Paper, 2022) is a decentralized application (DApp) (Marchesi et al, 2020;Wu, 2019) that implements DAO algorithms. It combines the functions of private web hosting, a secure audio-video-text communication system and a payment system, as well as an environment for developing and executing custom DApps.…”

The paper discusses the current state and development prospects of Web3 and decentralized autonomous organizations in comparison with Web 2.0. The problems of interaction between participants of decentralized autonomous organizations within the virtual space and integration of a decentralized autonomous organization with the outside world through network inducement algorithms are raised. The possible implementation of such interactions is considered on the example of TheOoL DAO. The functionality of TheOoL DAO is briefly disclosed, aimed at ensuring the security of participants in a decentralized autonomous organization, the complete suppression of the "digital footprint" they leave. The classes and forms of financial relationships of participants in a decentralized autonomous organization are determined. A mathematical model of billing in the serverless secure Internet TheOoL DAO on smart contracts is presented as an integral part of the TheOoL cloud computing and data storage subsystem. This system provides guaranteed automatic payment for services for the provision of computing power for storing and processing data or performing computing tasks and, at the same time, performs the functions of fully automatic control over the execution of the terms of a smart contract by the owners of these capacities.

“…Wessling et al [55,56] discussed the design choices of the architecture of a software that involves blockchain, showing the benefits and drawbacks of DApps. Wu et al [57,58] conducted empirical studies on Ethereumbased DApps to show the popularity, growth, development practice, cost, and the open-source status quo. They pointed out the research direction in the synchronization between the on-chain and off-chain layers of a DApp, but no further study has been conducted.…”

Since the emergence of Ethereum, blockchain-based decentralized applications (DApps) have become increasingly popular and important. To balance the security, performance, and costs, a DApp typically consists of two layers: an on-chain layer to execute transactions and store crucial data on the blockchain and an off-chain layer to interact with users. A DApp needs to synchronize its offchain layer with the on-chain layer proactively. Otherwise, the inconsistent data in the off-chain layer could mislead users and cause undesirable consequences, e.g., loss of transaction fees. However, transactions sent to the blockchain are not guaranteed to be executed and could even be reversed after execution due to chain reorganization. Such non-determinism in the transaction execution is unique to blockchain. DApp developers may fail to perform the on-chain-off-chain synchronization accurately due to their lack of familiarity with the complex transaction lifecycle.In this work, we investigate the challenges of synchronizing on-chain and off-chain data in Ethereum-based DApps. We present two types of bugs that could result in inconsistencies between the on-chain and off-chain layers. To help detect such on-chainoff-chain synchronization bugs, we introduce a state transition model to guide the testing of DApps and propose two effective oracles to facilitate the automatic identification of bugs. We build the first testing framework, ÐArcher, to detect on-chain-off-chain synchronization bugs in DApps. We have evaluated ÐArcher on
