dApps (Decentralized Applications) are applications that do not rely on traditional servers. Instead, dApps make use of Blockchain to host the data traditionally stored on the servers. The data is stored across the network of nodes connected to the Blockchain. Various tools and frameworks are used to write full-stack, decentralized applications. One such popular framework for writing dApps using the Solidity programming language is Truffle. Truffle provides a basic scaffolding to design dApp projects. Using Truffle, we can create the smart contracts required to create the blockchain functionality, write unit tests for the functions, and design the front-end design of the dApp. The basic steps for designing a full-stack dApp are as follows:...
In this article, we will be deploying smart contracts on blockchain from back-end, so that we do not have to require hardhat or truffle frameworks and their commands to deploy a smart contract or if somebody doesn’t want to use these frameworks. Since we have to run manual commands of these frameworks in the terminal to deploy Smart Contracts. We can directly deploy smart contracts by simply running the function in the node i.e. if somebody wants to deploy a smart contract on click from the front-end, we can easily connect the contract deploying function to the front-end through node REST API....
With the growth of the crypto market, the demand for blockchain has increased and people are seeking various possibilities of growth and taking interest in blockchain as a service platform. There are so many applications of blockchain which are the best things of blockchain as a tool platform for business. Its applications are making the scope of Blockchain as a tool platform broader day by day over time and blockchain as a service platform can be used independently from a cryptocurrency....
The BlockChain, to begin with is undeniably one of the most ingenious inventions of mankind. Considering it to be the brainchild the pseudonym, Satoshi Nakamoto, the technology has evolved into something unimaginably great. However, the most commonly asked always arises every single time – What is this Blockchain?...
Let’s see some basic terminologies first as follows:...
REST, or Representational State Transfer, is an architectural style for building web services. It is based on a set of principles that define how web resources should be defined, accessed, and manipulated. One of the key principles of REST is the use of the HTTP protocol for communication between clients and servers. This means that REST APIs are based on the same principles as the web itself, which makes them easily accessible and widely supported. The article focuses on discussing REST API in Hyperledger....
The goal of Zero-knowledge proofs (ZKP) is for ‘verifier’ to prove itself as possessor of some information called as ‘witness’ to ‘verifier’ by satisfying some relations and not revealing witness to anyone else. Interactive zero-knowledge proof requires live interaction of verifier and prover. The idea underlying zero-knowledge proofs first came to force back in 1985, when developers Shafi Goldwasser, Charles Rackoff, and Silvio Micali presented to world notion of “knowledge complexity”, concept that served as precursor to ZKPs....
We have passed the time when blockchain was used only in the form of cryptocurrency. Today, it is being used in a broader domain and it’s going to dominate in the coming future. As per the latest reports, it is expected that corporations will spend around $20 Billion on blockchain technical services by 2024. Industries like Healthcare, Insurance, IT, Finance, etc. have started implementing blockchain technology in their respective field to centralize the whole system. Blockchain has emerged as one of the most powerful technology ever which holds the accountability to make every data secure & decentralized into encrypted form without the need for any 3rd party involvement. In other words, it is used to send data in small segments “BLOCKS” which holds the complete set of information....
To get the deployed smart contract address in the truffle follow the below steps:...
The architecture of dApp or Decentralized applications is quite different from traditional applications. Decentralized applications require a unique system design to achieve high security, reliability, and privacy....
Hyperledger is an open-source collaborative effort created to advance cross-industry blockchain technologies. It is a project of the Linux Foundation and is designed to support the development of blockchain-based distributed ledger technologies (DLT) for a wide range of applications....
The rise of blockchain technology has opened a new era of financial innovation. However, the decentralized nature of blockchain also introduces unique security challenges. Lockchain.ai appears as a frontiersperson in this landscape, offering a first-of-its-kind AI-powered risk management platform specifically designed for blockchain assets....
