This study aims to develop a blockchain-based smart contract (BBSC) system for smart payment in the construction industry by focusing on the fundamental cycle of payment freezing (sometimes also synonymously called payment guarantees) and disbursement application. Firstly, a BBSC framework, containing...
A blockchain-based smart contract or a "smart contract" for short, is a computer program intended to digitally facilitate the negotiation or contractual terms directly between users when certain conditions are met. With the advance in blockchain technology, smart contracts are being used to serve ...
Data uploading needs security and privacy in the cloud. But there are some problems like centralized provenance data (PD) collection, storage, lack of secu
Blockchain-based Smart Contracts: A Systematic Mapping Study An appealing feature of blockchain technology is smart contracts. A smart contract is executable code that runs on top of the blockchain to facilitate, execute and enforce an agreement between untrusted parties without the involvement of.....
Through the notion of smart contract automated interaction between and existing transaction system is discussed. A solution for the issues like security, abuse of investor and illegal transactions in crowdfunding process is prompted in this project.The idea behind model is to use ethereum based smart...
Smart contractInteroperability AdaptabilityBlockchain, the technology Bitcoin lives on, is an emerging research field due to its nature of decentralisation, and properties of data immutability and transparency. Smart contracts are the programs executed on programmable infrastructure provided by blockchain, ...
Furthermore, we design a new system for storing and trading vehicle information based on the Ethereum blockchain and smart contract technology. Specifically, our system allows users to upload vehicle information and auction vehicles to transfer ownership. Our application provides great convenience to ...
Timed transaction execution is critical for various decentralized privacy-preserving applications powered by blockchain-based smart contract platforms. Such privacy-preserving smart contract applications need to be able to securely maintain users' sensitive inputs off the blockchain until a prescribed executi...
**《ABlockchain-basedApproach for Data AccountabilityandProvenance Tracking》**(基于区块链的数据问责和溯源追踪)是提出了三种基于publicly auditable contracts(此处可以理解为smart contract智能合约)的模型,具有不同的的粒度(granularity)和可扩展性(scalability)。
