Hard disk can also mine: Chia mining tutorial

What is the ChiaChia project was initiated in August 2017 and is the next-generation blockchain-based smart contract platform. Bram Cohen is the founder of Chia, you may not have heard of him, but you must have used BT download, yes, he is the inventor of BT download.

After more than three years of development, the Chia mainnet was launched on March 17, 2021, and mining started at the same time. The development team hopes to realize a global financial and payment system through Chia. Moreover, Chia is also the first blockchain digital currency for enterprise level.

Chia designed a new language Chialisp for its smart contracts, which is a more powerful, easier to audit and more secure smart contract programming language. The biggest feature of Chia is its consensus algorithm. It does not use common Proof of Work (PoW), but uses Proof of Time (PoST). Therefore, Chia mining does not need to consume a lot of electricity for calculations, but uses more easily available storage space. The hard disk capacity is the computing power, which is in line with today's environmental protection concept.

Let's look at the parameters of Chia:
Block time: 16 blocks every 5 minutes
Pass: XCH Block reward: 2 XCH per block, halved every 3 years, after halving 4 times, the reward is fixed and no longer halved
Consensus algorithm type: Proof of Space and Time
Consensus algorithm: NakamotoChia

In the consultation on the difference with Filecoin, I found that many friends confuse Chia and Filecoin, both of which use hard disk mining, but there are essential differences. Filecoin is actually the incentive layer on IPFS. It focuses on storage and bandwidth sharing. The hard disk is used to encapsulate and store user data. You can think of it as a decentralized cloud disk. Chia does not provide storage services. The data stored in the hard disk is completely meaningless. It is stored for storage, which proves that you really have such a large hard disk space.

Filecoin has a high mining threshold. If you want to mine, you need to purchase FIL as a mortgage. If your mining machine's online rate does not meet the standard, the mortgaged FIL will be partially or completely confiscated, which can really achieve negative returns. This design mainly takes into account the service availability. If you are a user and purchase a storage service with FIL, you don't want to wait for the data storage machine to be offline when you want to use the data. Therefore, Filecoin needs to use this mortgage mechanism to force miners to optimize technical solutions to ensure long-term online.

At the same time, if Filecoin wants to store user data, it must first download the user data through the network, and then upload it to the user when the user needs it. This requires a lot of bandwidth resources. Obviously, this is not what ordinary household broadband can meet. Compared with Filecoin, Chia has a lower threshold. On the equipment, hard drives have far more advantages than graphics cards in terms of power consumption, cost, and supply. This is why it has been sought after by everyone recently. Linyuan Xianyu, it is better to retreat and network, let us experience Chia mining. First of all, wallet software
Go to Chia's official website to download the wallet software.

According to your operating system, choose a version. After downloading, you will get a similar file. The number behind is the version number, which may be different with the software upgrade.

Generating a wallet address for mining will generate revenue. We need to prepare a wallet address to receive these revenues. Open the wallet software, you will be prompted to generate a wallet address the first time you start it.
Record the 24 mnemonic words generated. These mnemonic words can be used to generate the private key. If it is leaked, it will cause the private key to be leaked and the coin will be stolen, so be sure to keep it properly. After recording, click NEXT.

Similar to most wallet software, Chia's official wallet is also a full node, and it takes a while to synchronize block data. We can start mining preparations while synchronizing the block data with the wallet. Mining is different from other currencies that use graphics cards or ASIC mining machines. Chia's mining algorithm is very special. It needs to fill the hard disk with data in advance. This data is called Plot. This process is called Plotting and is used to generate Plot. The software and machine are called Ploter.

The more Plots you store, the more space it takes up, and the higher the probability of digging a block, you will naturally get more benefits. In Chia's world, hard drive capacity is computing power. In order to prevent cheating by sharing Plots between miners, Plots are associated with private keys. Plots between different miners cannot be interchanged or shared. You can only buy hard drives yourself and generate Plots yourself. Let's take a look at how to generate Plot, which is commonly known as P disk.

Each Plot will take up 101.4G of space. The following is the number of generated Plots, which can be selected according to the available space of your hard disk.

Continue to slide down to set the location of temporary files and Plot storage. When a plot is generated, a large number of temporary files will be generated and frequent read and write operations are performed. Therefore, it is recommended that temporary files be placed on the SSD. Then click CREATE PLOT.

Plot generation takes a long time. After the generation is completed, it will automatically enter the mining mode, and you will see the corresponding Plot display as Farming.

Click Farm on the left to view the detailed mining information. If you can see the word Farming, everything is normal, and your income will be displayed under XCH Total Chia Farmed.
