Artificial intelligence and blockchain: A review

Abstract

It is irrefutable that blockchain and artificial intelligence (AI) paradigms are spreading at an incredible rate. The two paradigms have distinctive level of innovative nature and multidimensional business propositions. Blockchain innovation can robotize instalments to grant a way for exchanging personal records, information, and logs in a secure, and decentralized manner and can be revealed digitally in the digital currency era. As of late, blockchain and AI are two of the most trending technologies. Blockchain can administer connections among members with no mediator via smart contracts. AI, then, offers insight and dynamic capacities for machines just like people. In this survey, we provide a comprehensive overview about the applications of AI in blockchain. We audit, and sum up the rise of blockchain applications, and stages explicitly focusing on the AI research area. We likewise recognize and summarize open challenges in using blockchain and AI techniques. We also classify the effect of the cloud with these two innovations with respect to the computerized economy, which includes Blockchain as a Cloud and Blockchain as a Service. We moreover survey difficulties and issues identified while provisioning these technologies. It has been found that the integration of AI and blockchain is trusted to make various prospects. Such techniques provide scientists and authorities with an accuracy of up to 90% when taken properly into consideration.

Blockchain for the Metaverse: A Review

“…As a common feature, blockchain ledgers provide an audit trail, which can be used to check the accountability of all transactions occurring in the metaverse. A zero-knowledge evidence system enables individuals to identify critical facts in the metaverse while also protecting their privacy and retaining ownership of their resources from deepfakes [97]. This will prevent AI from exploiting resources in the metaverse.…”

A survey of application research based on blockchain smart contract

“…Blockchain smart contract technology can trigger execution when conditions are met, which reduces human intervention, making applications for IIoT more powerful and secure. Its data security will also bring additional advantages to 5G technology, big data and artificial intelligence [211][212][213]. However, how to integrate and innovate blockchain technology with other information technologies and give full play to its potential value of application is the biggest challenge at present.…”

A traceable privacy‐aware data publishing platform on permissioned blockchain

“…According to the privacy restrictions, the blockchain is divided into the public blockchain and the permissioned blockchain. Permissioned blockchain is composed of a set of known, identified nodes that might not completely trust each other 6 . The permissioned blockchain servers are administrators, which are trusted by other nodes 7 .…”

“…Permissioned blockchain is composed of a set of known, identified nodes that might not completely trust each other. 6 The permissioned blockchain servers are administrators, which are trusted by other nodes. 7 Permissioned blockchain allows nodes to join the network after their identities are authenticated by the administrator, specifies nodes to perform only specific activities on the blockchain, 8 supervises the identities of nodes, and improves the security of the permissioned blockchain network.…”
