As we discussed in our previous article Generating a random number on the Blockchain, Chainlink-VRF is a preferred way to get a provably random number into your smart contract. So, let’s dive in to see how it actually works. Request and Receive cycle? Using chainlink data feeds, to asset pricing data like the ETH…

In our previous article The Oracle Problem & Decentralized Oracles, we discussed the oracle problem and its solution. Chainlink is one of them. Chainlink: Chainlink (LINK) is a both cryptocurrency and technology platform that enables non-blockchain enterprises to securely connect with blockchain platforms. Chainlink is middleware that connects blockchain-based smart contracts…

As we know, smart contracts are similar to the contracts that people make between each other in the real world but instead of writing these contracts on pen and paper, the terms are written in form of code and automatically executed by the decentralized blockchain network instead of being executed…

As we know blockchain is a deterministic system and this is super ambitious because it allows us to do all these smart contracts and have a system that can actually reach consensus very easily. Random numbers are much harder in deterministic systems. Assume a blockchain with a whole bunch of…

Creating a New Project The first step to using Brownie is to initialize a new project. To do this, create an empty folder and then type: brownie init Structure of a Project: Every Brownie project includes the following folders: contracts/: Contract sources interfaces/: Interface sources scripts/: Scripts for deployment and interaction tests/: Scripts for testing the project brownie-config.yaml…

No transaction cost. Accounts can be re-cycled, reset and instantiated with a fixed amount of Ether (no need for…

“Bitcoin” -the evergreen red-hot topic, but how is eth different from bitcoin. Bitcoin is primarily designed to be an alternative to traditional currencies and hence a medium of exchange and store of value. Ethereum is believed to be better off than bitcoin because of its real-world applications that can store…
