PictoBlox is an educational programming software with block-based coding and Python Programming that makes coding fun and easy. With a user-friendly interface and drag-and-drop functionality, it is the ideal companion for setting the first step into the world of programming. One can learn to cod...
It is found that the Fabric project is developed by Google's programming language GoLang, so we also use the Go language to develop smart contracts in this exercise. Download the binary package of Go language version 1.11 from the Google website to the local, and extract it to the /usr/...
contracts are automatically loaded and then executed according to their predefined logic (as specified bycodeHash). In Fig.1, we show a simple contract namedEtherBankin Solidity. Solidity is the statically typed object-oriented high-level programming language dedicated...
Web 3.0 technologies allow immutable and trustless interoperability, enabling powerful new applications to eliminate the need for companies to act as trusted third parties, which has been a major barrier to achieving data security and privacy in the modern era. The Open Science DAO (OPSI) is an ...
Casbin is a powerful and efficient open-source access control framework. Its permission management mechanism supports multiple access control models. Casbin configures the permission model through a configuration file and divides a permission model into request policy, policy effect, and matches. Compared...
Mini.ai is a high quality, powerful plugin. However, "it enhances some builtin textobjects". There are benefits to this approach, but also some disadvantages, as stated by the author. I was considering a pull request for LazyVim, preventing mini.ai from taking over the tag textobject: {...
We implement Pub-SubMCS on the Ethereum blockchain using Solidity as the programming language. We use the brownie framework [44] to develop, test, and deploy smart contracts on Ganache. As the brownie framework is based on Python, we have written Python scripts to deploy the smart contracts...
Finally, Section 4 introduces a novel Trust Consensus System, making it powerful to be used not only in blockchain processes but also for other tasks such as service provisioning between peers. Section 5 concludes with a theoretical and experimental evaluation of the new proposed consensus protocol...
For instance, blockchain technology was conceived for an Internet scenario with powerful computers, and this is far from the IoMusT reality, which mostly relies on embedded systems. The sweet spot, as always, is in the middle. Permissioned blockchains may bring an improved level of trust, ...
wherein distinct computing components, which are functionally and architectural different from each other, are arranged to interact so as to provide a novel technical result. The interaction of the different computing systems (computing resource and blockchain) results in a highly powerful control ...
