Testnet
A testnet, in the realm of cryptocurrencies, refers to a separate blockchain network specifically designed for testing purposes. It allows people involved in the crypto industry, such as companies, protocols, and blockchain networks, to experiment and evaluate their developments without risking real assets or interfering with the mainnet, the live blockchain network. Testnets simulate the functionalities of a blockchain network, enabling developers to identify and rectify any potential issues or vulnerabilities before deploying their projects on the mainnet. This testing environment serves as a crucial tool for ensuring the security, efficiency, and reliability of various crypto-related applications, including decentralized finance (DeFi) protocols, smart contracts, and crypto exchanges. By utilizing testnets, developers can refine their innovations, enhance user experience, and mitigate potential risks, ultimately fostering the growth and advancement of the broader crypto ecosystem.
Hello, Hoodi: Ethereum Welcomes a New Testnet
Ethereum's 'Pectra' upgrade will be tested on Hoodi following buggy attempts on other testnets, Holesky and Sepolia.
Ethereum Developers Postpone Pectra Upgrade Following Buggy Tests
After two buggy tests, Ethereum's developers have decided to spend a bit more time collecting data on the highly-anticipated Pectra upgrade.

Ethereum’s Holesky Testnet Fails to Launch, in Rare Tech Misstep for the Blockchain
Developers of the Ethereum blockchain say there was a misconfiguration in the genesis files of the test network, and now they plan to try again in about two weeks.
Ethereum Blockchain Launches 'Holesky' Test Network, on First Anniversary of Historic 'Merge'
The debut of the testing system – designed to be twice as big as the main network so developers can simulate massive scaling, comes a year after Ethereum completed its historic "Merge" shift to a "proof-of-stake" model from the original "proof-of-work" setup that Bitcoin uses.
