Unexpectedly, the target of the miners' fight that day may not be their peers, but "Song Jiang".
On the same day, a large number of mining nodes encountered DDoS attacks, which made it worse for miners who were already busy solving node operation problems and adjusting configurations and parameters.

t01475 Changes in computing power
A team said that the webpage traffic of the browser it developed surged, and the server pressure was too high, causing problems with page access. In order to deal with node operation problems and respond to DDoS attacks, technicians have been busy all night recently.

Nodes are frequently attacked
On the first day of the launch of the "Big Miner Test Reward Program", apart from the frequent good news of block generation from various nodes attracting attention, another loud voice was related to DDoS attacks.
Many miner nodes have become targets of attack. Diancun Technology Lio told Beep News that its cluster node t01155 encountered multiple attacks after qualifying, and the attack bandwidth reached 21Gbps;
Binhe Yunzhi Wu Yibo told Beep News that Binhe Yunzhi also experienced a low-intensity attack last night. This may be a tentative attack. "The top miners of the entire network should have been scanned once." The pomegranate mining pool also stated in the community that its own nodes were radiated in this wave of attacks.
The so-called DDoS attack, that is, Decentralized Denial of Service Attack (distributed denial of service attack), during the attack process, the server will receive a large number of request reply information within a certain period of time, and the network bandwidth or system resources of the miners will be consumed in large quantities, which is more serious In some cases, the server network or system of miners will be paralyzed, and normal services cannot be provided.
Why these nodes are attacked, and the reasons behind it, both the node team and community users have mentioned the word "big tree attracts wind".

The Filecoin network has very high requirements for the stability of node operation. If the miner submits the space-time certificate late, he needs to pay a fine. If it is confiscated, the effective computing power will be cleared to zero.
In the face of such a strict punishment mechanism and large-scale attacks, even though miners have a strong need to "show off their performance" and "show off their muscles", many miners still choose to act in a low-key manner.
Many miners do not disclose their node accounts, or delay the disclosure process. Li Bai, the core technician of Pomegranate Mine Pool, said in the community, "The nodes (of Pomegranate Mine Pool) will be made public one after another. Once they are all announced, they will become the target of DDoS."
However, not disclosing nodes does not mean security. Binhe Yunzhi Wu Yibo told Beep News that "node IP is public information, (nodes) will be "beaten", (miners do not disclose nodes) may only be able to resist some people and organizations that they know or have premeditated attack."

Who is "Song Jiang"?
So, who is the initiator(s) of the DDoS attack in this Filecoin big miner test game?
Whether it is the WeChat community, the slack community or the media, "Song Jiang" has been mentioned. This is a Chinese miner, a "trouble maker" in the Filecoin community.
On August 19th, Filecoin officially announced the launch time of the big miner test in the slack community. When the community members celebrated the official announcement of the launch date, "Song Jiang" published an article titled "Filecoin, a "centralized "Storage Network" article.
From the perspectives of miners’ mining success rate data not necessarily credible, big miners monopolizing Filecoin mining, the game’s official players also playing football, and the game’s lack of fairness, it points out that “the Filecoin project is heading for a road of no return. The rules are becoming more and more unfair, and the network is becoming more and more centralized.”
In addition, "Song Jiang" also bluntly stated in the article that "we will try to carry out DDoS and other forms of attacks on the top miners of this Space Race until their order success rate is lower than the official threshold."
"Song Jiang" plays the opposite role of the Filecoin official and the big miners in the Filecoin ecology. Therefore, whether it is a miner or the media, when guessing who is this round of attackers, the first thing that comes to mind is "Song Jiang".
When the media reports about the attack on the node, they will quote "Song Jiang"'s previous remarks about attacking the mining node; community users will jokingly say "Congratulations on being targeted by Song Jiang" when discussing that the node is attacked and the current situation is not good. "Song Jiang doesn't look easy to deal with."
However, the party "Song Jiang" published a Medium article last night, stating that he had nothing to do with this round of attacks, on the grounds that it was of no benefit to attack on the first day.
In fact, attacking nodes is expensive. Why, a member of the Filecoin team, once said that "attackers cannot really carry out DDoS attacks on every miner. Although they can, they will cost more money than competitors", and the attack cost is higher than the mining cost.
Network information shows that the cost of Filecoin mining includes mining machine costs, operation and maintenance costs, etc. The price of any Filecoin mining machine on the market ranges from tens of thousands to hundreds of thousands, and the attackers have to fight against hundreds of thousands of dollars. One mining node, the cost threshold can be imagined.
As for who the attacker is, there are basically two views in the community at present. One view is that it is a spontaneous geek testing behavior such as "Song Jiang", and more people believe that this involves a conflict of interests among miners. There are "Li Gui" who take advantage of the momentum to attack, which is a manifestation of malicious competition in the market.

Interesting tests, "sandbox experiments"
While miners are fighting through the night to deal with attacks like DDoS, some community members are also optimistic about the attack. They believe that the attack will be beneficial to the entire network, and cyber attackers can act as a catalyst to urge miners to build proper defenses. mechanism, which is beneficial to the robustness of the entire network.
When describing the Filecoin market, we usually use the description of "barbaric development". "In such a non-open sandbox experiment, ecological participants are also marching savagely.
The Filecoin world, which is based on mechanisms, algorithms, codes, and data, has produced so many interesting phenomena under the influence of human participation and human nature:
The official launch of the bug bounty program, miners are fighting each other for computing power, stability, fighting for success, and even malicious competition. There are also shouters like "Song Jiang" in the community who want to awaken the real "decentralization concept". Make a bifurcated voice... Some of these phenomena are good, and some reflect the "evil" side.
This is a wealth contest, and it is an impromptu experiment. No one knows what direction Filecoin will develop. Even the official Filecoin team is in a hurry. After the leak, the official team forced out four or five versions within 12 hours."
This big miner test reward program is quite interesting.
