Has anyone set up a ready to run install for the RPi for this? Looks awesome. But I'd rather not tie a PC up, running a Pi with my miners seems to me like the best way to go?
p2pool needs a high power PC. Running it on RPi would be real bad.
Concur. CPU performance aside, the RPi does not have the raw I/O performance necessary to cope with reading/writing both the blockchain and the sharechain. The getwork latency would be astronomical.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

I fixed a few things in the segwit implementation. Please update if you are testing it.

I have, but just for fun, it would be pointless for mining....

p2pool needs a high power PC. Running it on RPi would be real bad.
Concur. CPU performance aside, the RPi does not have the raw I/O performance necessary to cope with reading/writing both the blockchain and the sharechain. The getwork latency would be astronomical.

4 cores in the pi 3, as long as your not stuffing phs down its throat it should be fine. The IO issue can be solved by booting off the sd card and then mounting a usb drive as the root filesystem post-boot (or using u-boot to boot the usb drive directly, and just have an sd card for the u-boot and firmware portions).

Out of the box with an sd card, there is no way the IO would ever be fast enough. If they ever finish the compute model for pi 3, that may be an option as I believe its emmc and much faster than regular sd card (or USB) IO.

The RAM is the next issue you would run into. p2pool itself on bitcoin chews about 700mb ram (on one of my systems). Pi 3 comes with 1GB ram. You could run p2pool on one pi 3, no wallets/daemons would work in the remaining amount of ram.

Ya I figured it was to much to ask for Smiley
I love the idea of the peer pooling, would like to see it built into mining controllers, getting away from centralized pools all together

I'm sorry but I discovered another little bug. Please update.

Happy Thanksgiving P2Pool'ers! 

I've been mining with P2Pool for about a year now, made it thru the 16.0 update, but would welcome your opinions on the upgrade to Segwit. Is the current github update compatible, or will Forrest post something official on his website?

Cheers 🍻

Still useless. Extra cores, but all of them run slow as shit.

Per CPU core performance is everything for p2pool, especially since it's python which is mostly single threaded.

I agree.

I use an E7500 ( http://ark.intel.com/products/36503/Intel-Core2-Duo-Processor-E7500-3M-Cache-2_93-GHz-1066-MHz-FSB ) and the whole process of full node & P2Pool need 20-25% of dual processor at any time.

Look the MOY. indicator on the bottom-right of this screen :

Sweet! We got another block. As usual, we received next to zero transaction fees.

How can you say it's tiny!
  Do you have any scales or anything else ?  Huh Grin

P2Pool will produce blocks with witnesses upon activation on the P2Pool network, which can happen before activation on the Bitcoin network. Bitcoin Core doesn't accept such blocks before activation (even though it could strip the witnesses) so I made it so appropriate block representations will be submitted through the RPC interface.

Please note that submitting via the Bitcoin P2P network doesn't work anyway since headers-first synchronisation (P2Pool doesn't support the getheaders message).

just an update for those merge mining Huntercoin.

There is a hardfork due tomorrow so don't get stuck on a bad fork.

https://github.com/chronokings/huntercoin


you may also try with https://github.com/chronokings/huntercore/tree/0.13
which is based on the latest bitcoin-core code. (you will need to addnodes for now)

Any issues please post in the main huntercoin thread.

Thanks
