    Yes it takes longer on a Pi, but 3 days for ~200,000 does still seems slow.

    @awrell RasPi3 doesnt see much improvement the real bottleneck here isn't even the SD card, or the processor even, but the 1GB of ram.

    @phonikg
    @5chdn Did you attach the HDD/SSD via USB? Because RasPi only supports USB 2.0 which has a max throughput of ~40-60MB/s. This is actually MUCH slower than high level SD cards which run @ 95 read/90write.

    @w-eth Emailed proposal and updated reddit. I was vague with a few mechanics because, as I understand the problem, the priority is usability, that its open source, and so there are more nodes. I'm confident that it can be done in a decentralized way and I'd utilise a part of the grant to implement the Pulse protocol, or, find a superior protocol which would take its place and manage porting that protocol to the various clients. I saw several projects at DEVCON1 which could be suitable for the mechanic and parts of casper are also candidates.

    @5chdn @awrelll I stand corrected on my earlier comments regarding mSD throughput speeds... there is an apparent limitation on the RasPi hardware that bottlenecks throughput to a ceiling of ~20-25MB/s no matter the speed rating of the mSD card.
    This is however where the benefits of Hardkernel using eMMC's on their Odroids. Newer revisions of eMMC standard can reach speeds of 400MB/s.

    @phonikg I also have to admit I didn't know the micro SD cards were so advanced in speed nowerdays. I'm still using very old cards and attaching an HDD via USB 2.0 allows major I/O improvements.

    @phonikg
    Yeah, and it makes a lot of sense... Gives more insight into how bottlenecked everything is with the Pi when it comes to throughput... All USB share resources with Ethernet, SD interface caps at ~20MB/s... Actually pretty horrible in comparison to slot if their competition.

    Hi @phonikg LG from fuzo.com here now with stability of Ethereum code base we are looking to make a Proof of Concept with with our embedded SIM service - for storing private Keys
    John Gerryts
    @phonikg
    Hello @FUSED-ID big fan of your concept! I know of a few bitcoin hardware projects that are now looking to include Ethereum, although none as unique as yours.
    Anything I can do to help?

    @FUSED-ID
    Hi Thanks for the support - we are supporting Ethereum in our roadmap
    My Lead Dev has chatted to Vitalik and its more than a concept
    http://quorumwallet.com/faq looks like an early bridge to a solution as we wait for our chipset production run
    Ethereum builds on Raspberry Pi and other SOCs is our focus but all would have our stack - with an onboard (slot or soldered down) hardware embedded SIM -(called a eUICC) -
    Anything I can do to help?
    Yes please - contact me at LG@Fuzo.com as I'd like to work with other embedded systems people that are ETH enthusiasts to build a standard solution that will work in a range of ETHEmbedded scenarios including the orchestration of devices via your Smartphone - with a HW token used for Trust and IDentity
    John Gerryts
    @phonikg
    Fantastic, well I'm definitely interested.
    Leon-Gerard Vandenberg
    @FUSED-ID
    eventually the entire - smartphone and IoT products & sales channel will change to embrace eSIM inside handsets and devices

    Hello, anyone responsible for pool bounty program?
    John Gerryts
    @phonikg
    That would be @w-eth ...
    Sammy Libre
    @sammy007
    I have full-stack ether-pool solution: it's redis backend + pool in golang that consist of proxy, json-api (stats), payouts module, block unlocking module, policy module (for security), beautiful emberjs frontend
    John Gerryts
    @phonikg
    Demo link?
    Sammy Libre
    @sammy007
    No demo, I killed it due to luck of funding, I can post screenshot for now, but will make demo indeed
    Also it works with my already long ago published https://github.com/sammy007/ether-proxy
    John Gerryts
    @phonikg
    If you have not yet, I would read this blog post:
    Sammy Libre
    @sammy007
    I must write set up guide but I can push code almost in 1 hour
    John Gerryts
    @phonikg
    It says to email grants@ethereum.org
    I would read the blog post clearly to ensure you meet their set requirements.
    Sammy Libre
    @sammy007
    So tl;dr is to publish code, go spread it and pray if someone will use it and pool ops will go from 1% and up to 18% of network?
    John Gerryts
    @phonikg
    TL;Dr is go read it if you are serious about submitting. I am not part of DEVgrants and they set the requirements that you must meet to be eligible for funding.
    Sounds like you have a good submission. I am a miner and would use the pool service funded by DEVgrants myself personally
    John Gerryts
    @phonikg
    That's awesome, a entirely open source pool is good for the entire eco system.
    Good luck @sammy007 !!

    Hope to see it live and running @sammy007 !

    @sammy007
    Only testnet for demo, I am not going to launch pool again, my solution is always pays full block reward instead of scamming miners for up to 5% with 5 ETH static block reward bullshit.

    @sammy007
    I won't publish under MIT, it's just stupid, what license devs prefer? GPL-2 or 3?

    sammy007: Received your email, cheers.
    sammy007: We'll be in touch. Waiting on a conversation with Vitalik.
    FUSED-ID: Received your email, too. :) Replied back to Leon.
