Abstract: Chia was created by Bram Cohen, the inventor of BitTorrent and the best network protocol engineer. Chialisp is Chia's new smart transaction programming language, which is powerful, easy to audit and safe. Currently available smart transactions include: atomic swap, authorized payee, recoverable wallet, multi-signature wallet and price limit wallet. This article introduces Chia's P disk tutorial in detail.

What is Chia?

Chia was registered in August 2017 to develop an improved blockchain and smart trading platform. We are building the Chia network to improve the global financial and payment system. Chia will be the first enterprise-level digital currency. Chia uses the first new Nakamoto consensus algorithm since Bitcoin. It is called "Proof of Space and Time" and was created by Bram Cohen, the inventor of BitTorrent, the best network protocol engineer currently. Chialisp is Chia's new smart transaction programming language, which is powerful, easy to audit and secure. The smart transactions currently available for reference are: atomic swaps, authorized payees, recoverable wallets, multi-signature wallets and price-limit wallets.

Differences from traditional mining

Unlike BTC and ETH which use Proof of Work (POW), Chia uses "Proof of Space and Time" to mine using the remaining storage space in storage devices (computers, servers, NAS, Raspberry Pi).

Before starting mining, you need to sow (plots) in the idle hard disk space, and then the farmer (farmer) looks for the best answer to the block explosion on the already sown P disk files (plots files). The essence of Chia hard disk mining is to write encrypted data to the hard disk first (plots process), and then the mining program looks for the best answer in the P disk file (farmer process), so the higher the total capacity of your P disk file relative to the total network capacity, the easier it is to explode blocks, and the corresponding mining income is also higher.

The seeding process requires CPU, memory (each P disk thread requires 4G memory space by default) and hard disk temporary space (generating a seeding file with K = 32 specifications requires about 332G temporary space). Therefore, it is recommended to use a CPU with better performance, more than 16G memory and a solid state drive (M2.NVME protocol SSD with a total of more than 2T is recommended) for the seeding (Plots) process. Refer to the Plots platform hardware configuration table

P disk file specification list

The plots host configuration used by the author is as follows

CPU: i9-10900k

Memory: 64G

SSD: 2X2T M2.NVME protocol SSD

The mining process does not require too many system resources. In theory, any storage device that can run a farmer can be used for mining.

Of course, the seeding (P disk) device and the mining device can also be the same machine. The following tutorial is to seed and mine on the same machine.

See mining hardware.

Mining Tutorial

1. Download the latest version of Chia-Blockchain wallet.

Download address: https://github.com/Chia-Network/chia-blockchain/releases

Figure 1

2. Run the installer as an administrator

Figure 2

3. After the installation is complete, the Chia wallet will run automatically. You need to create a new key for the first run.

4. Back up the mnemonic phrase. It is recommended to save it properly by taking a screenshot. The mnemonic phrase is one of the important ways to restore the wallet, so it is very important. Do not lose it or disclose it to others.

Figure 5

5. After backing up the mnemonics, click Next and the wallet will run smoothly.

6. Click the Plots menu on the left to enter the P disk management interface. In the P disk management interface, click the "ADD A PLOT" button to create a P disk task.

Figure 7

7. Select K=32 for the P disk file format. For the first time seeding, it is recommended that you select 1 for the number of P disk files. Select SSD solid state drive for temporary storage space (1 P disk thread needs to occupy 332G of temporary space. Too little space will cause seeding failure). The final storage path for P disk files can be the partition of the mechanical hard disk. P disk files with K=32 specifications will eventually occupy 101.4G of hard disk space.

8. After the P disk is completed and the wallet block is updated to the latest, the mining journey begins.
