With the emergence of the crypto bull market for more than a year, a large number of new participants are added to the block, and there are many opportunities for the trend chain at the same time, but it also makes the circle appear a large number of new low-level plans, which is Strangely, someone was selling the ethereum test currency online recently, and there were really a lot of white bait, and I bought a lot of it. After getting to know it, many novices mainly don’t know about blockchain, and there is very little relevant science popularization, so some information has caused misunderstandings. Therefore, we carried out novice science popularization, mainly introducing the Ethereum test network.
As the name suggests, the test network is a functional and performance testing process before the official product or program is launched. Different public chains have their own test networks, such as Bitcoin, Litecoin, Ethereum, etc. Test networks are generally divided into dedicated test networks and public test networks. A private test network is a test environment built from our LAN or local machines. A public test network refers to a test network environment accessible to everyone. Generally speaking, in the Ethereum Metamask wallet we can see that the Ethereum public test network is mainly divided into the following types:
Ropsten: a POW blockchain, very similar to the current Ethereum Mainnet
Kovan: a POA blockchain
Rinkeby: a POA blockchain
Goerli: a POS blockchain, right Marked ETH2.0
In addition to differences in block models and identification mechanisms, different test networks also have different types of software client support and garbage processing transaction mechanisms. Everything else is different. It is a virtual machine entrance that supports the use of EVM, that is, if it is not the Ethernet channel and underlying functional testing or some DApp performance parameters, for ecological projects, everything else is the same.
Before the bull market, most Ethereum DApp developers actually used the Ropsten test network. Because the Ropsten test network uses POW mining, which is the same mining we see on the main network, specific graphics cards and other equipment are required. The biggest feature of this part of the test network is that the network computing power is low, so the collection cost is very low. In addition, with the funding from the Ethereum Foundation, it is actually easy for the public to obtain the corresponding test coins for free through public channels. Mining methods and other testing, so the cost of testing, is cheaper, anyway the cost of acquisition, of course, in the industry test network does not have much commercial value, while testing the coin has no value, is available for free, people can tap the test network for free website.
After entering the Ethereum 2.0 era, the main process of the main network is that the beacon chain is officially launched, the node verifies the ETH pledge, the node software runs, and then the POW chain is converted into a POS chain. The smart contracts deployed on the original POW network still work, but the mining methods have changed, a process that has made it necessary to run multiple test networks with different mechanisms before functionality goes live, in order to ensure that the official launch can go as smoothly as possible.
On the main network, the current progress is that the Ethereum beacon chain is online, the POW chain continues to run, and other shard chains are not yet running. The current mainstream 2.0 client test network is the Goerli test network initiated by Prysmatic Labs, which has been running since 2019. Tapoz, the test network for Ethereum 2.0, has been running since 2021. Other open beta shard chains are still not publicly operational. After the Ethereum 2.0 merge, the Goerli testnet is now known as the Ethereum 2.0 testnet.
Since it is the Ethereum 2.0 test network, as the focus of the development of blockchain technology in the next few years, the Goerli test network is actually quite popular. First of all, you need to participate in the block generation and operation of the test network verification node, so you must need 32 Golli test network test coins. Prysmatic Labs previously provided 32 Goerli test coins on its official website for operators who intend to participate in verifying test nodes to receive them, which fully meets the requirements of test nodes.
After the validator obtains 32 test coins, he needs to pledge the Gaolli test coin calling contract on the Gaolli test network just like the current main network, in order to obtain the qualification to run the test node. Then run the test network client software on the server to complete the subsequent test network participation process. After the test network validator completes the establishment of the test network verification node, it can try to deploy various smart contracts or conduct other tests on the test network validator.
The corresponding process on the main network is the transition from the POW main network to the POS process, which we will see later. In other words, if a project wants to deploy on Ethereum in the next few years, the closest test network is the Goerli test network. Of course, since EVM virtual machines are used for contract deployment, many projects will still choose the Rinkeby test network for testing. The Rinkeby test network adopts a POA authentication mechanism (authoritative authentication) and uses a validator to unify the ledger status. This effectively prevents double spending.
Because of this, the Rinkeby testnet actually provides developers with a good testnet experience and attracts many developers.
The Gaoerli test network currently operates in POS mode, and a large number of test coins are generated every day. However, due to the current shortage, some testcoin faucets are offering relatively few testcoins to the public. As can be seen from the above, the main purpose of the Gaolli test coin is to deploy corresponding 2.0 validator test nodes for the 32 test coins. Of course, test nodes will not generate actual revenue.
In addition, the main users of Gaolli test currency are DApp ecological project parties. As Ethereum plans to enter the 2.0 phase, some projects will deploy their test dapps on Goerli's network, so there are not many smart contracts deployed on Goerli's test network. Since the bull market, the Gaoerli test network has also ushered in a more active period, which is partly due to the test network activities of DApp projects attracting a large number of wool parties.
In short, after the project officially launches the main network, the DApp development team usually deploys the test network contract in the public and then makes it public so that users and some DApp bounty hunters can test it. Some bugs were found that were not found in internal testing to ensure the safety of the project.
Ecological project testing activities generally have corresponding bonuses. Some projects at the same time conduct stress testing DApps to access streaming applications, and publicly announce some testing activities, such as following official social accounts, and then Experience the test network, and when the project is established and officially provided, you will get the project deletion token.
There is almost zero cost because of this test activity and valuable tokens are obtained, which attracts many ordinary users. At the same time, a large number of accounts are used to "pluck", and there will be a test network that will be used The premise of testing eth gas is that because of this, many trial coins are mostly used when the bull market accepts the leader (the trial coins are brought out, and the trial coins cannot be obtained), so there is a situation of trading trial coins.
For most investors in the currency circle for a long time, they naturally know that test coins are worthless, so buying test coins is mainly done by some black-hearted businessmen and novices in Ethereum and I don’t understand the details of Ethereum Square 2.0 - 2.0 test, and some articles clearly express the test network, causing some misunderstandings for novices. The purpose of testing a currency is always to test the network. After the main network is launched, the test network still exists and plays a testing role in subsequent key functions, instead of falsely stating that "the test network and the main network merge, and the test currency becomes the main network currency" said these black businessmen.
