[∞ YH] US/EU/SG/AU solo.ckpool.org 2% fee solo mining 316 blocks solved!

solo.ckpool.org now has a unified stratum endpoint for all the servers at stratum.ckpool.org. This will automatically choose the lowest latency pool for your endpoint, and fail over to the next nearest in the unlikely event of any outage or internet routing issue.
Stratum connections are very long-lived, so if you do fail over, you may not fail back even when the best pool is available again.
You may still use the existing direct configurations to each of the pools but without the advantage of failover support. It will however guarantee you only ever connect to the endpoint of your choice.

US East server now added to http://solo.ckpool.org.
Using stratum.ckpool.org will direct you to the lowest latency server or fail over to the next nearest in case of connectivity issues, but you can still manually choose your own server from the mining endpoints:
US west uwsolo.ckpool.org
US east uesolo.ckpool.org
Germany eusolo.ckpool.org
Singapore sgsolo.ckpool.org
Australia ausolo.ckpool.org

CK, I've been pointing my rigs to the new stratum address for a couple of days and all was running well, my rigs are in the US and my software tells me they're still running properly.

But I can no longer find them via web browser at solo.ckpool.org/users/MY-BTC-ADDRESS.

Given the rig's location, I suspect they moved over to the new US East server once that went live. What is the correct web address to access a miner's stats/status on US East? Is it supposed to be the same old: solo.ckpool.org/users/ADDRESS... or should we now direct our web browsers to uwsolo.ckpool.org or uesolo.ckpool.com?


EDIT: I do see the miners through the graphical stats page (the new stats) which shows miners are connected and active mining is happening. But I prefer the old simple text page (now I no longer can find my miners there).

Use http://raw.stats.ckpool.org/users/$address as that checks all servers and collates the stats

thanks. the speed dropped from 90ms to 27-30ms to East US

Legendary @ckpooldev adds experimental SV2 endpoints.

stratum2+tcp://sv2solo.ckpool.org:3336/9anrRNhBh7869XtNnFcCuGBRZP51E635qGbu457J5kHdszhfRc3 - Non JD

stratum2+tcp://sv2solo.ckpool.org:3337/9anrRNhBh7869XtNnFcCuGBRZP51E635qGbu457J5kHdszhfRc3 - JD Support

Can you tell us what is JD?

Great, thanks

Update after the first day of experimental stratum v2 support.
The sv2 pool is currently sitting around 300TH from 6 users/10 workers (including my own hashrate) and all seems to be working fine.
For those configuring SV2 mining, the mining endpoint is:
stratum2+tcp://sv2solo.ckpool.org:3336/9anrRNhBh7869XtNnFcCuGBRZP51E635qGbu457J5kHdszhfRc3 
high diff for rentals:
stratum2+tcp://sv2solo.ckpool.org:4336/9anrRNhBh7869XtNnFcCuGBRZP51E635qGbu457J5kHdszhfRc3 
and the job declaration endpoint is:
stratum2+tcp://sv2solo.ckpool.org:3337/9anrRNhBh7869XtNnFcCuGBRZP51E635qGbu457J5kHdszhfRc3

Assuming SV2 is here to stay, these URLs will likely remain and propagate across all the pools. Stratum V1 mining is here to stay indefinitely and will be unaffected - they will both be running from the same ckpool code.
The ckpool code itself will eventually be made public once it reaches a stable state.
In addition I'm working on extending ckpool in proxy mode aka ckproxy to be a stratum v1 to v2 proxy. This will also follow the public release of ckpool with v2.

I'm also aware that some people took my initial post to be very negative regarding stratum v2, but that was not my intent at all - I was trying to describe the compromise nuances on a technical level. So I'll try to clarify:
- Native stratum v2 end to end is a positive on all fronts. My benchmarking v1 vs v2 on ckpool specifically shows latency is basically identical. The advantages are security, privacy, and a trivial bandwidth decrease.
- Stratum v1 to stratum v2 via a proxy I can now say after benchmarking it has no significant latency increase so can still obtain many of the benefits of Sv2 but is currently not that straight forward to set up.
- Stratum v2 with job declaration (mine your own templates/transactions) is a decentralisation aid that comes with a modest latency hit tradeoff. It is significantly more complex to set up than basic v1 to v2 proxying. It should become the defacto standard for regular pooled mining, but _currently_ offers no advantage in lottery aka solo pools. Hopefully highlighting this will help the devs focus their attention to minimise or even abolish the tradeoff in time.
On a technical level, I think pools should be allowed to send work in JD mode on an updatedtip and simply allow the client to decide whether to use that work or not until it updates its own tip. It will provide the best of all worlds. Leaving the decision to the client takes away the concern that a pool will override the client's work. I have been in discussion with the sv2 devs and they are open to the idea.

Mine on!

Can someone help me with the new update?

It was about time for eusolo.ckpool.org to finally mine a block.
