About the Test

This test can help you identify candidates that have prior experience in Blockchain and Smart Contract development.

Ethereum is a decentralized, open-source blockchain platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk.

This Ethereum test looks at the candidate’s understanding and abilities in Ethereum Basics, Ethereum Accounts, Transactions, Nodes, Clients, and Networks.

1

Accounts

In Ethereum, there are two types of accounts: external accounts that are controlled by private keys and contract accounts that are controlled by code. External accounts are owned by individuals or organizations, and they can send transactions to contract accounts or other external accounts. Contract accounts, on the other hand, are controlled by code that is executed when a transaction is sent to the contract account.

2

Transactions

A transaction is a message that is sent from an external account to either another external account or a contract account. A transaction contains a payload of data and is signed with the private key of the sender. When a transaction is sent to a contract account, it triggers the execution of the contract’s code.

3

Nodes and Clients

In Ethereum, nodes are computers that run the Ethereum software and participate in the Ethereum network. Nodes can be either full nodes or light nodes. Full nodes store the entire Ethereum blockchain and validate transactions and blocks, while light nodes only store a portion of the blockchain and rely on full nodes for validation. Clients are software programs that allow users to interact with the Ethereum network.

4

Networks

Ethereum has several networks, including the main Ethereum network, test networks, and private networks. The main Ethereum network is the production version of Ethereum and is used for live, decentralized applications. Test networks, such as the Rinkeby test network, are used for testing and development purposes. Private networks are custom Ethereum networks that can be created for private, internal use within an organization.

5

Ethereum Basics

Ethereum is a decentralized, open-source blockchain platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud, or third-party interference. The Ethereum platform is powered by Ether, a cryptocurrency that is used to pay for transaction fees and services on the Ethereum network.

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.

Frequently Asked Questions for Ethereum

The Ethereum assessment is a process used to evaluate an individual’s knowledge and skills related to the Ethereum blockchain and the Ethereum platform. Ethereum is a decentralized, open-source platform that enables the creation of smart contracts and decentralized applications (dApps).

The Ethereum assessment can be used by recruiters and hiring managers to evaluate candidates’ ability to design and build smart contracts and decentralized applications using the Ethereum platform and related tools such as Solidity, web3.js, and Truffle.
