[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[jtoomim]

I've just updated http://toom.im's two nodes, http://74.82.233.205:9334 and http://74.82.233.205:9332. Together, these two nodes provide about 400 TH/s to p2pool, or about 20% of p2pool's total hashrate.

If you need to set backup or replacement nodes during the upgrades, you are welcome to use ours.

updated, no problem (hobbyist miner).  
i use a 0.11 RC2 of Bitcoin Core, too...  

[Meuh6879]

Progression look good ...

Forrest, thank you!

CoinCadence will be upgrading on Monday, one of the best features of p2pool is it's decentralization, if you are mining on the minefast.coincadence.com node please be sure to set your backup nodes to another reliable p2pool node, while I hope the upgrade goes smoothly, I will likely mess something up for an hour or so be sure to take advantage of our decentralized nature and have good p2pool backup nodes set in your miners....

Well, it's not decentralised when you centralise a bunch of users onto one p2pool node ...

The decentralised side of p2pool is everyone running their own p2pool, not lots of people mining on one p2pool.

Well, it's not decentralised when you centralise a bunch of users onto one p2pool node ...

Coincadence has about 40 TH/s. That's not exactly what I'd call centralized. Maybe neighborhood-ized?

People are going to mine on others' nodes.  For example, I don't advertise my node at all, yet I've regularly got a few people mining on it besides myself.  Windpath has done a bunch of work and is very active here in the p2pool community, so it's natural that people would mine on his node.

There certainly are plenty of nodes out there, with plenty of people mining on them.  There are also a few nodes that are popular, like windpath's and OgNasty's, that get the extra traffic.  In an ideal world, sure, everyone would be running their own node.  Until then, I think we can all safely say that p2pool is definitely the most decentralized bitcoin mining pool out there.

Edit:

Oh, the upgrade to 14.0 took all of about 30 seconds, windpath .  You should have plenty of time while the kids are napping.

...

It's the only one

Any other pool that says it is ... is lying.
As is a certain case well known.

I was referring to the mistake of confusing the two terms.
When you get a bunch of people all mining together on one node, it's centralised ... even if p2pool itself is decentralised by design.

Fair enough... and that certain pool's false claim of decentralization is definitely well known .

Actually I was not, just sat down to get started, something funky happened this morning, will update when I know more...

[Meuh6879]

[Meuh6879]

DONE : more than 50% have moved to v14.

OK, back up and running on p2pool 14.

Not sure what happened this morning, took the opportunity to do a hard reboot the server, first time in over a year

Thanks again Forrest!

As a side note, seeing lots of blank lines in p2pools output that were not there before:



Any ideas?

Edit: Due to the upgrade the links to the alternative front ends in my site footer will not work, I'll re-install them next week.

[Meuh6879]

Perhaps, the power of mining system ... on my little miner, just 1 blank line randomly.
Perhaps, blank line = number of miners connected on the node ?

windpath is upgrading.

any eta mate ?

Actually I was not, just sat down to get started, something funky happened this morning, will update when I know more...

OK, back and and running on p2pool 14.

Not sure what happened this morning, took the opportunity to do a hard reboot the server, first time in over a year

Thanks again Forrest!

As a side note, seeing lots of blank lines in p2pools output that were not there before:



Any ideas?

Edit: Due to the upgrade the links to the alternative front ends in my site footer will not work, I'll re-install them next week.

From forrestv yesterday:

i'm seeing this, lots of blanks, the blank space are normally where it says new work for worker ! diff xxx share diff xxx & block value but in my case only 1 worker shows up n the rest are blank. getting shares though.

i have several workers at same & other add's but they are at different worker diff's which i normally see.

That should be normal. The patch accepted from midnightmagic throttles the prints from different workers. I'm not sure why it's printing blanks, though - I'll look into it.

Thx JB, missed that one

Seems to be operating as expected.

DONE : more than 50% have moved to v14.  

I was under the impression that the most important goal was 95%, not 50%. The 50% threshold just means that people will get upgrade notices now. If we don't get to 95%, we will see reductions in mining efficiency once BIP66 takes effect.
