March 19
Filecoin’s official developers announced in the Slack group that they would restart the “interoperable network” that started the testing phase, while the official technical director, Why, also sent a message inviting community miners to participate in the test, again mentioning 1475, and humoring everyone to note 1475 while the iron is hot.
Shortly after the interoperable network was restarted, it was seen that the official technicians were discussing the amazing speed of the top two counters, both of which were confirmed to be from the 1475 team.
On March 20
We are honored to invite Flora, marketing director of 1475 team, to be a guest of “Filecoin technology frontier” column of star horizon, and talk about the hot spots, key points and technical points of Filecoin mining.
01
IPFSNEWS: we all know Filecoin is a mining project. Could Flora first explain the whole process of mining Filecoin?
The 1475 team Flora: Filecoin usually consists of two parts: power (growth of effective power) and mining (explosive block).
The growth of effective computing power consists of four steps:
(1) order issuance. At present, the major miners all adopt the brush mode, so this step does not exist at the present stage;
(2) processing orders on the trading chain, which was not required in the previous network version, also requires chain verification from testnet2, so mining optimization starts from this step;
(3), series of complex encryption process, which contains an attachment \ precommit1 \ precommit2 \ commit1 \ commit2 five-step, 1475 miners scheduling team will these algorithms to optimize technology and to seal the whole time significantly shortened, the final step is to verify that this takes a cut in all subnets to verify your store is effective, validation completed can obtain effective work force.
(4) mining, the process of mining also involves several steps, which is simply to calculate and obtain the right to package blocks based on the EC consensus. The more departments you have, or the more effective calculation power you have, the probability of your winning the lottery will be estimated and the income will increase.
Here’s to the experts, Filecoin innovatively USES “take the prize” instead of the block reward, is a more equitable consensus innovation;That’s why we say that mining revenue is closely related to efficient computing power, and I won’t get into the technical details, but those interested can talk to each other privately.
02
IPFSNEWS: Filecoin itself is a storage application, but now everyone is “brushing”, many people are worried that the project will not eventually become a mining game?
1475 team Flora: this is a chicken or the egg problem, stand in the Angle of the project, at the beginning of the project, real and effective storage needs very little, can brush by allowing a single behavior and dig Filecoin rewards to encourage more miners more access to the hardware devices, so as to ensure the stability and robustness of the entire network.
Only when the feasible network architecture is sufficiently complete and robust can more developers be attracted to the actual application development based on the ipfs/filecoin network.
In addition, Filecoin not only provides mining rewards, but also storage rewards and retrieval rewards. In the later stage, in order to obtain more profits, miners are bound to receive more real demand for storage orders, which will form a virtuous circle of effective resources to expel garbage resources. Therefore, we hope that we can view this problem from the perspective of development.
03
Interplanetary horizon IPFSNEWS: mining is becoming more and more demanding on hardware. What do you think about it?
Flora, 1475 team: from the current situation, it is true that mining hardware requirements are very high, from the PC architecture to mining to the later must be professional server architecture;From CPU mining to GPU mining, from 8gb, 16gb to now 192g, 256gb and even higher, it seems that Filecoin is against the original intention of “enabling more devices to participate in mining”, but from an official perspective, the highest priority requirement is to ensure the safety and stability of the chain.
When security and stability are not guaranteed, it is unrealistic to talk about application and wide application.
We believe that, after the main online, the network will be further optimized, gradually reduce the mining cloud, brake can make more equipment involved, in a real ground level is applied to implement the official expectations, is just like the ETH, provids online for nearly five years, is still not fully transition from 1.0 to 2.0, it must be a long process.
04
IPFSNEWS: do you think the Filecoin mining GPU is necessary for mining in the future?
Flora: actually, this is a continuation of the previous problem. From the perspective of development, GPU mining is not necessarily needed in the future. In order to make more devices can participate in the network construction, it involves a long optimization process.
However, from the perspective of the present, the performance of GPU is much better than that of CPU in the calculation of EPoSt verification, so it can make mining more efficient and speed up.For example, CPU can be regarded as a university professor, GPU can be regarded as 100 primary school students, now need to complete 100 consecutive calculation problems in 25s, endless achievement will lose the qualification to answer the questions.
Most of the CPU may not be solved within 25 s time, excellent performance of CPU is reluctantly, but the GPU is more than can be done in a few seconds to a few seconds of time sequence answer, can also be done after this problem is to do the next question is, if the mining as a continuous process, so the GPU machines performance will be better than no GPU.
We have reshaped the entire physical architecture of mining and can now help gpu-free machines to achieve efficient mining.
05
IPFSNEWS: the launch of Filecoin’s official main network has been delayed many times. What are the chances of it going live in July?
Why did the technical leader of the Filecoin project reply that as long as I don’t die of coronavirus and as long as I don’t die of COVID 19, I will go online? Although it was a joke, it also grinds the determination and confidence of the whole team.
Standing under the technological focus, we 1475 team all the time according to the official development progress, I also get reliable information from engineer there code is now gradually close to the sealing plate, the technical architecture and main functions are also more perfect, the current from the main online and for more than three months, we are looking forward to the official launch on schedule.
06
Interplanetary horizon IPFSNEWS: what remains to be done for the launch of the main network of file COINS?
Flora: 1475 team don’t know if you have found that the official team in multiple places cross-referencing network security and stability, the large amount of work means the next is to ensure the security and stability of the whole chain, including the interaction of multiple implementations, the determination of consensus algorithm, economic model design and invite professional security code audit work for the third party team.
07
Interplanetary horizon IPFSNEWS: why did the authorities add a virtual implementation that included go-filecoin and lotus internals?
Team Flora: this can be compared with the operating system of mobile phone, including android, IOS, symbian, etc., and the four implementations of go-filecoin and lotus are the same. Different receiving methods, different systems adapt to different hardware devices, and there will be different algorithm optimization paths.
So it can guarantee the flexibility of the entire network and security, can receive more hardware equipment at the same time, it also feeder vendor provides more space, such as the 1475 team fundamental breakthrough in the whole mining section of feasible code, so you can understand as we have our own version of an implementation, like the go — filecoin and lotus are not receiving mode.
08
Interplanetary horizon IPFSNEWS: what is the collateral mechanism for miners?
1475 team Flora: speaking of mortgage mechanism, the existing official team has not yet been formally identified and disclosed, under the existing version, using the rear mortgages, the network will be according to the entire network in circulation, the enumeration number, effective number of storage, the dynamic calculation of each number of Fil analysts need to mortgage the future the piece reward priority priority mortgage guaranty money, can transfer withdrawal partly more than.
In short, there are 3 points:
(1) number of members of the whole network
When the number of shareholders in the network is larger, the less collateral is allocated to each node.
(2) the effective storage proportion of the court
The more collateral you need, the more your abstract is effectively stored online.
(3) the amount of tokens in circulation throughout the network
When the size of the entire network of tokens in circulation, the more collateral needed.The final version is still awaiting official notification.
09
Interplanetary horizon IPFSNEWS: are there rewards for stage 2 miners?
Name of 1475 team: the AMA of the official team a few days ago is believed that everyone has also paid attention to this issue and has replied to it. The original words are that there is no such issue at present, and we will know everyone once we are sure.An initial plan is to announce the full incentives on April 13th.
It is only a temporary plan, or we should patiently wait for the official announcement, we miners only need to make full preparations, once the incentive method is confirmed, the first time to participate in mining can be ok.
Wait for the flowers to bloom.

Interplanetary horizon IPFSNEWS: the most concerned aspect of everyone’s participation in mining is the increase ratio of investment. How does 1475 improve mining efficiency?
Flora: in the previous question, I also briefly mentioned our technical implementation of 1475, which has two main aspects.
(1) software algorithm framework
Almost the entire mining process was reshaped by our team and the algorithms for each module were optimized to different degrees, including the previously mentioned sealing part and the mining algorithm part, which is why the mining efficiency/effective computing power of the mining machine in 1475 increased very fast.
(2) hardware
1475 mill itself built-in acceleration module, you can talk with our perfect matching algorithm, at the same time do technical development team and at the same time, based on the chip, we found that in the process of some calculation chip level optimization can obtain ideal result, but based on the chip of the high cost of r&d and filecoin network has not yet completely stable, is currently in the experimental stage, has not been mass production.
