Stale shares là gì

     
When I mine at a pool, only a part of my shares are accepted. There is a small percentage which is marked as stale.quý khách hàng đã xem: Stale shares là gì

As far as I know I only get paid for accepted shares, so what are these stale shares và how can I avoid them?

Stale shares are the shares that were sent after a bloông xã was already solved, that is lớn say, they were sent late & were no longer valid. To avoid stale shares, best lớn have sầu a reasonably fast mining rig (so you won"t take too long to lớn calculate a cốt truyện, probably not a problem for most machines), reliable internet connection (stable, not necessarily fast), but also an up-to-date mining software (if you are mining with some really old miner it might not communicate in the most efficient manner with the pool).

In short - update your miner every now và then, make sure your mạng internet is running okay, & don"t mine on really weak rigs.

The percentage of stale shares should be very low if everything"s working correct, around 2 out of 1,000 shares or so.

Several factors affect the stale cốt truyện rate. The three most important are long polling, pool load, & miner-to-pool latency.

When the long polling notification goes out, all miners that support long polling request new work units at about the same time. This generates a massive sầu burst of load as the pool has lớn manages lots of network traffic & vì chưng several SHA-256 operations for each giới thiệu it issues. If the pool is slow lớn issue you a new work unit, the window in which you can generate stale shares increases.

The long polling & subsequent cốt truyện request process requires a few network operations. Latency between the miner & the pool can slow this process down. Picking a pool with a controller near you (network wise) can reduce this part of the stale chia sẻ window as well.

In addition, some pools have sầu had bugs in their software that produced stale shares. The pool checks if the nói qua is stale by seeing if it has a record of the work unit & clearing all work unit records when the chain changes. So if something goes wrong with the work unit tracking process, that will result in a stale mô tả being reported.

I probably shouldn"t admit it, but I was actually responsible for one such bug. My first implementation of long polling in the hozo.vn client rushed as quickly as possible lớn sover out the notifications of a new bloông xã being discovered to miners -- so quickly that some miners could request new work units before the client had finished processing the new blochồng and they got work units based on the old block. Any shares they submitted based on those work units would be reported as stale.
