The blockchain community is flocking to Filecoin. In 2017, Filecoin easily raised 257 million US dollars, becoming the largest ICO project at that time; before the Filecoin mainnet was launched, the FIL mining machine and futures market had been developing wildly for several years.

The test network was exposed to have infinite issuance loopholes
On the evening of May 28, some currency circle media published an article claiming that the Filecoin test network has an infinite issuance loophole.
Pomegranate mining pool (6Block) technicians found a serious loophole in the Filecoin code, through which the unlimited issuance of Filecoin can be realized. In addition, in order to verify the validity of the loophole, the three accounts t01043, t027999, and t0234783 under the Pomegranate Mining Pool have achieved 4.8 billion additional FILs (1.6 billion per account, 16 is a homonym for "Pomegranate") through this loophole. Ranked in the top three of the FIL Rich List.
According to the information provided by 6Block Li Bai to Beep News, after the announcement of the additional issuance method, users in the community have issued 9.3 billion FIL on the testnet, but these additional FIL will not be converted into mainnet tokens at that time.

The video provided by Li Bai to Beep News shows that the additional issuance method of FIL is actually very simple. A bls address type account also has an account address starting with "t", and FIL can be realized by sending tokens to the account address through the bls address. Unlimited additional issuance (see the end of the article for the specific video). In addition, Li Bai said that this loophole should be fixed next week.
Fundamentally speaking, the FIL unlimited issuance vulnerability is not a big problem, but the status of the miners behind the Filecoin testnet vulnerability is embarrassing.
Chain Catcher recently wrote in a report on Filecoin, "The original intention of the Filecoin test network is very good. It can not only provide more than 1 million token rewards for technical miners participating in the test, but also the test results can become the best for these mining machine manufacturers. Good advertising”, but the very real point is that the mechanism will always be broken by human nature.
The second-stage public beta of Filecoin has become a place for many mining machine manufacturers to show off their muscles on the list.
When talking about the vulnerabilities of the Filecoin testnet, Li Bai said, "At this stage, there will definitely be vulnerabilities. After all, the purpose of the testnet is to let everyone find bugs, but there are many mining machine manufacturers in China who do everything they can to get on the list. The loopholes are exploited instead of reported to the authorities, which is not conducive to the entire ecology in the long run.”
The purpose of mining machine manufacturers to dominate the list is to sell mining machines and cut leeks.
The information in the Chain Catcher article shows that many intermediary full-time sales companies without machines or technology will choose to rent IDC computer rooms or even supercomputing centers for testing. Machine and participated in the public beta to obtain the ranked miner number, so as to publicize in the future, saying that its own machine has high performance, so as to achieve the purpose of acquiring customers.

The extreme perfectionism complex of the Filecoin project party
In addition to additional vulnerabilities, when the second phase of the Filecoin testnet was first launched, it was also exposed that there was a "pre-mining vulnerability".
On May 15th, after the second phase of the Filecoin testnet was launched, the ecological team t01475 said that it had found a loophole in the official Slack and reminded the official, but this loophole still exists after the second phase of the testnet was officially launched.
Li Bai told Beep News that the impact of this vulnerability is that miners pre-dig some blocks before the main network goes live, and these blocks have a certain chance to be applied to the subsequent main network, which will lead to unfair pre-mining behaviors.
At present, whether this problem can be properly and quickly resolved, Beep News has not yet obtained clear information, but behind the exposure of the vulnerability, what we see is the extreme perfectionism complex of the Filecoin team and the possibility of another postponement of the mainnet.
In order to find an optimal solution, it is very likely that a perfectionist will take action without hesitating to invest huge time and capital costs, or even overthrow all reconstructions.
At the end of last year, in order to increase the randomness of block producing nodes and increase the cost of attack, the Filecoin team stated that it would increase election proof (Selection Post) and GPU mining in the mining mode; in May this year, in order to encourage early miners to store valuable Data, Filecoin has launched an official mining hard drive; Filecoin team members also confirmed to Beep News in an AMA that the proof mechanism will be modified later, and it is even possible to make changes after the mainnet goes live.
Therefore, whether it is the launch of the mainnet or other progress, there are always changes and uncertainties in Filecoin, and every time when answering the community's question about "whether the mainnet will be postponed", the answer given by Juan or the members of the Filecoin team is always The "safety and stability" of the main network is the fundamental goal. This cannot be guaranteed, and the main network may always be in a "stuck" state.
In stark contrast to the project side's pursuit of perfection and prudent development, the Filecoin community is very anxious.
A number of exchanges, including Gate.io, WBF, Wan Hakka, Lbank, Bifu, Hotbit, etc., have successively launched FIL futures for internal trading; in the past three years, the number of mining machine sales teams or companies in the Chinese market is not fully counted The number of Filecoin miners has reached 500, and the value of Filecoin mining machines sold has reached 50 billion yuan; founder Juan listed more than 60 Filecoin miner ecological logos in a recent AMA...
The world is waiting for the gorgeous debut of the Filecoin mainnet, but this process has already gone through and will inevitably undergo revisions and repetitions. Perhaps we need to give more time and patience to wait for the mainnet to go live and for Filecoin to truly bring the token economy to the world The storage and retrieval market has brought a storm of popularity to the blockchain and cryptocurrency markets.
