How much impact does the life cycle of filecoin network sector have on miners?

浏览次数:101 分类:公司新闻

With the disappearance of a small number of sectors on the filecoin network, the discussion about the sector duration of the filecoin network and the renewal of the filecon sector in the later stage is becoming more and more intense. Next, let’s talk about the “sector life cycle”.

 

What is sector?

 

Sector is the basic unit of storage on filecoin. It has a standard size and a clear commitment period. It provides digital storage services similar to containers in global freight transportation. The size of sector balances security and availability.

 

According to the white paper “creating a filecoin economy”, the life cycle of a sector is determined by the storage market, and the period promised by the sector is specified (that is, if there is a real order, it depends on the requirements of the real order).

 

If we compare sectors to containers, it is the containers full of data (encapsulated sectors) that together build a huge filecoin storage market.

 

So what does sector failure mean?

 

When the data in the container full of data disappears, there is no data stored in the container. Analogy to the filecoin network, that is to say, when the data stored in the sector is full disappears, the sector will fail, and the sector failure means that the corresponding computing power of the sector disappears.

 

Thinking about sector life cycle

 

The sector of the filecoin network is 540 days by default, but miners can modify the sector time. Therefore, the sector life cycle of the filecoin network can be automatically set to any value between 180 and 540 days (180 days, 360 days and 540 days are more common). Due to the seamless connection between the filecoin space race and the main network, the, The start time of the life cycle of the filecoin sector is 06:00 Beijing time on August 25, 2020, which is the start time of the filecoin space race.

 

Taking August 25 as an example, sectors with a 180 day sector life cycle have actually expired on February 21, 2021.

 

Why do some miners set a 180 day sector life cycle?

 

We all know that the disappearance of sectors means the disappearance of computing power, and the disappearance of computing power means the sharp decrease of miners’ income. After all, in the filecoin network, miners get block rewards by virtue of effective computing power. If there is no effective computing power, where can they get block rewards?

 

Therefore, from the perspective of miners getting block rewards, the longer the sector cycle is, the better.

 

So why do miners set a sector period of 180 days?

 

Because the sector is due, it also means that the pledge money will be returned to the miners at one time, so the miners will have more fils.

 

Does setting a 180 day sector life cycle have more advantages than disadvantages?

For the old miners, most of the sectors are packaged during the space race, and the gas fee and pledge money during the space race are almost zero. Now, the cost of adding 1tib effective computing power to a 32gib sector is about 20 fils.

 

Obviously, for the miners, although the life cycle of the sector can be arbitrarily selected between 180-540 days, the life cycle of the sector is as long as possible, and the probability is the best choice, because compared with the space race, the cost of new packaging 1TB of effective computing power is too high!

 

Can the filecoin sector be renewed?

 

Combined with the above, we clearly know that compared with repackaging the computing power of 1tib, it may be more cost-effective to maintain the original computing power to obtain block rewards.

 

Then, can the filecoin sector life cycle be renewed?

 

Sectors encapsulated in sectors on November 24, 2020 (November 24, UTC time, November 25, Beijing time), i.e. V1 sectors, cannot be renewed.

 

Sectors encapsulated after November 28, that is, v1.1 sectors, can be renewed.

Why is November 24 the dividing line for renewal?

 

Because there is an important version upgrade on November 24, that is, lotus is upgraded to v1.2.0. The upgrade of this version needs to be completed before 265200 height

 

 

Fip-5 removes the expensive calculation of miner reward ownership from precommitsector and confirmsectorprofsvalid, which helps to reduce gas consumption, release chain bandwidth and reduce miner cost;

 

 

 

Specs actors upgrade to v2.3.2;

 

 

 

Proofs is upgraded to v5.4.0;

 

 

 

Re adjust the cost of gas, mainly reduce the cost in onverifypostbase;

 

 

The upgrade of this version has fixed some bugs. Therefore, the official setting of filecoin is that before the bug is fixed, the sector of filecoin network cannot be renewed. After the bug is fixed, the sector of filecoin network can be renewed.

 

How to renew the sector life cycle?

 

Just send extendsectorexpiration to the network to renew.

 

At present, spatiotemporal cloud has successfully renewed some sectors.

 

What are people still talking about in the community?

 

Filecoin officially launched a FIP proposal, which mainly discusses whether sectors (V1) before November 24 can be renewed.

 

Official members said in the proposal:

FIP proposal

According to the existing code, some sectors that used V1 proof before can’t be postponed completely. For the miners who encapsulate this sector, if they can’t delay the sector, it will cause great losses, and it will cause a waste of computing and storage resources. Because the miners re encapsulate these sectors, they will need more mortgage and gas costs.

V1 sector

In other words, the authorities consider that although there are some bugs in the V1 sector, if the V1 sector can not be renewed, then the gas fee, pledge money and network congestion that miners need to spend to repack the sector are a waste of resources. Therefore, filecoin officials want to hear the community’s opinions on whether V1 sector can be renewed.

 

So, in the community discussion on whether V1 sector can be renewed, what’s your opinion?

 

Now, there are more and more proposals about the filecoin network. In fact, the filecoin network belongs to the community and is the embodiment of each and every one of us. With the joint support and efforts of all of us, the filecoin network will become better and better!
