Blockchain-based smart contracts have different challenges, opportunities, and applications in various fields like cryptocurrency systems, real estate, agriculture, logistics, and fire industry. The codes that can be executed and which operate on top of a blockchain to facilitate, implement, and ...
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 ...
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, ...
Smart contracts enable developers to write distributed programs based on blockchain systems, ensuring that all code is immutable and secure. In this paper, we analyze the security of blockchain technology to illustrate its advantages and justify its use. Furthermore, we design a new system for ...
Systemic protection via blockchain-based smart contracts This study proposes a different method to protect the swarm from harmful misinformation, an information market. The market’s economic rules can be enforced on a decentralised robot swarm through blockchain-based smart contracts, designed to rewar...
