call the functions defined in your deployed smart contract using the Ethereum Wallet interfacecode a simple, smart contract and deploy it to the Rinkeby network using the Ethereum Wallet UIcode, deploy and interact with a smart contract that includes a constructor which takes in an argumentconnect a new node to the private Ethereum network and add it as a peer of the existing nodeconnect to an already deployed contract using the Ethereum JavaScript API and invoke its methodscreate a private blockchain network using the Geth CLI and connect to it as a nodedefine Ethereum-specific terms such as mining, ether, and smart contractsdescribes at a high level what the process of mining involves and the role of Ethereum's cryptocurrency - Etherdescribe the functions of smart contract bytecode, opcodes, and ABI in interacting with a contractdescribe the need for smart contracts to eliminate the need for a trusted third party in many transactionsdescribe the purpose of the MetaMask client for Ethereum and the techniques it uses to connect to an Ethereum networkdescribe the role of miners in picking up initiated transactions and then ordering and verifying themdescribe the role of the transaction nonce in preventing replay attacksdescribe the trie data structure that is used to represent associative arrays and distinguish it from its space-optimized version, the Patricia trieidentify the characteristics of full, light, and archive nodes in Ethereumidentify the details required when invoking transactions in the Ethereum networkidentify the different networks available to test out smart contracts and describe their unique featuresidentify the flaws in the proof of work algorithm and how the proof of stake algorithm can address themidentify the role of digital signatures in authentication and non-repudiation of transactions while also ensuring their integrityidentify the roles of solc-js and the Remix IDE for developing smart contracts written in the Solidity languageidentify the two types of Ethereum accounts - externally owned and contract - and the data that is needed for each of theminstall the MetaMask extension for the Chrome browserinstall the official Ethereum Wallet application and describe the UI options availableinteract with a contract deployed on the Rinkeby test network and track the mining of your transactionsinvoke a transaction on your deployed contract using the Remix interface and set transaction parameters in Metamaskinvoke a transaction with a smart contract by calling a function that changes the state of the contractlist the features of the Solidity programming languageoutline the concept of gas in Ethereum and the role of the gas price and gas limit fields in a transactionoutline the proof of work algorithm and the work which miners need to do to claim mining rewardsoutline the steps involved verifying transactions initiated in the Ethereum network
