A brief review of the second phase of testing: "1475's highlights"

1. 1475 The first unofficial node produced a block

At 6:00 on May 15, the second phase of Filecoin testing was officially launched. The miner node of the 1475 team in the second phase test network was t01102. At 15:20 on May 15, 2020, 1475 was the first to produce two blocks, becoming the first unofficial miner node in the entire network to produce blocks in this test.

2. 1475 block generation rate 90% time first

In the winning-post space-time proof, the official adopted the expected consensus mechanism EC, completing all work in just 25 seconds, and broadcasting the block package to the entire network for all nodes to verify the block, otherwise it is very likely to miss this round of block production. 1475 nodes have made some optimizations in the block explosion rate and stability, so the highest reached 100 rounds of full block production (screenshot of block height 19331).

3. 1475 blocks, the largest number in the network

From the second test to now, according to statistics, the total number of blocks produced by the entire network has reached 204,558 blocks. 1475 nodes ranked first in the entire network with 56,377 blocks produced, accounting for 30.41%.

4. 1475 Mining Coins Ranked First in the Whole Network

At that time, each block contained 18.16 test coin rewards, which means that 18.16 FIL were added for each block mined. This indicator is directly related to the miner's income. The mining income of the 1475 node has reached 1077133.75fil, accounting for 30.87% of the entire network. It is also the only miner node in the entire network with a mining income of more than 1 million FIL.

5. 1475 takes the lead in ranking first in computing power list

Node 1475 is the first unofficial mining node to surpass the computing power of all official nodes and top the computing power list.

Additional explanation: The reason why we were able to surpass the official version first is that the 1475 team optimized and revised the official version code as soon as possible, and implemented a dynamic balanced network mechanism with decentralized strong collaboration, making the computing power growth more stable and flexible.

6. 1475 effective computing power increased by 10T/hour

Within 30 minutes, the effective computing power increased from 800GB to 5.09TB, and within 90 minutes it increased to 10TB. At that time, the computing power growth ranked first in the 24H list.

97 1475 nodes (these machines are the 1475Pro mining machines sold externally) participated in this test.

7. 1475 effective computing power reaches the top again

Starting at 12:00 on June 6, the 1475 node conducted a computing power growth test. As of 18:00 in the evening, the 1475 node ranked first in the network computing power ranking with 1.40PB, accounting for as high as 22.03%. The 1475 node once again became the node with the highest effective computing power in the entire network.

Additional note: 1475's technical staff optimized the underlying code and coordinated and assisted each other between nodes, which greatly improved the seal speed. In addition, the 1475 team adopted the OSP (zero-knowledge proof outsourcing service) acceleration system, which has a dedicated computing pool to independently perform zero-knowledge proof, which has improved the acceleration to a certain extent.

A brief review of the second phase of testing: "Healthy competition, common growth"

1. The first node on the list of computing power: t01038

After the test network was launched on May 15, the t01038 node was the first to be listed and officially verified. t01038 was the first listed node in this round of testing (unofficial). 1475 learned that this node belongs to Force Zone (a technology-based company that has been promoting IPFS for a long time and deserves respect).

2. The node with the fastest computing power growth: t01075

During the peak period, the growth rate of t01075 node reached 13.46T per hour. According to 1475, this node belongs to the alliance node (the alliance node of several companies such as Xi'an Lingdong and China Community);

3. The node with the most stable computing power growth: t013854

From the 1475 browser, we can see that the t013854 node has steadily grown to the top 4 in terms of computing power in the early stage, and has done a good job in stabilizing the growth of computing power; and has also achieved relatively ideal results in terms of block production rate; 1475 learned that this node belongs to Star Continent (one of the earliest companies in Shenzhen to preach IPFS)

4. The most stable node for block generation: t01100

Throughout the second test, the t01100 node maintained very good results in both block generation and revenue, achieving a very high rate of return for the single T effective computing power;

There are also many nodes with remarkable performance, such as 15362, 3929, 2600, 17382, 1118, 1020, 1108, 1267, 1218, 1043, etc. There are many other nodes with excellent performance that are not listed here one by one. The filecoin ecosystem will be more beautiful and prosperous with everyone;

t01475 The original intention of the second test: "Test goal"

1475 participated in this test with the following three goals:

1. Test the latest code, obtain real test data, verify the technical architecture and solutions, and lay a solid foundation for the main network launch.

2. Test the effectiveness of operation and maintenance processing under various abnormal situations to provide guarantee and Plan B for the stable operation and maintenance of the main network.

3. Cooperate with the official to carry out order issuance and retrieval tests, and conduct chain-related security and stability tests at the official invitation.

1475 has always believed that in Filecoin mining, algorithm technology is the primary productive force, and the return on investment (ROI) is an important indicator for measuring mining. He also reminds himself not to fall into the trap of the ranking arms race.

1475 will always be committed to contributing to building a more stable and secure network, and is willing to work with more partners to make the Filecoin network a more stable, secure and valuable distributed storage network. I hope that the main network will be launched as scheduled, so that every Filecoin ecosystem participant will be the biggest beneficiary.

1475 wishes you all a smooth test of the 5PB big miner in advance, and we will see you in the next round of testing!

1475Important Tips

Filecoin investment mainly depends on the input-output ratio----ROI:

FIL mining itself is more of a venture capital behavior. The core is the input-output ratio, that is, how much effective computing power growth rate (GB/hour) an investor can obtain per hour when the unit capital (for example, 10,000 yuan) is invested in the main network. In theory, the higher this indicator is, the higher the mining income of miners will be.
