Speaking of upcoming conference in Austin, since I live here I can order t-shirts for attendants and meet them before the conference. Do we have a list of people who are going to Austin so I can contact them to have their sizes? I can also print other stuff like business cards, flyers etc.
I want to get both business cards and flyers printed for Austin but I wanted to see what got made for Berlin first. I am really interested in a black NXT T shirt but if I'm speaking I may wear something a little more formal. I have posted my hotel and flight info in previous posts and would love to have a meet up with you and anybody else that comes on Tues night before the conference. |

One final note. For the record, I am placing a backup copy of the password to the NXTcommunityfund into a stamped postal envelope addressed to James, and placing this envelope in my bank safe deposit box. Just in case. Because you never know...
You better be paying attention folks... there is more education in that statement than most of us got in school University!!!  It is said that humans are the only animal aware of their own mortality. Most aren't. |

Count me in.
I've been thinking about this whole 1000 TPS thing and have a basic question. If ANYBODY can be the node that generates a block, but a node with a low rate data link can't support 1000TPS, then are we saying that the NXT TPS chain is only as strong / fast as its weakest link?
I am guessing any node that can't keep up will automatically become blacklisted and they fall forever behind. Such low bandwidth nodes will need to run slim clients. Not sure how they will be able to send NXT James So we start by telling people they can forge NXT based on their stake, then blacklist them forever if they can't meet a certain level of performance? If this is true then we better stop telling people they can forge on their smartphones now, rather than later. Some promotional material may need to be changed to reflect a realistic cost of forging on a high TPS network. +1. Bingo. This is exactly where I was headed with this chain of logic. You know, there is some serious downside to having this Step X plan that nobody but BCNext and JLP fully understands yet. They keep hinting at conquer-the-world performance while the rest of us are down here struggling to write whitepapers and figure out how many Raspberries/VPSs/Odroids to get online to back it all up and there's just not enough knowledge or facts to do it efficiently from an engineering point of view or honestly from a marketing point of view. Not trying to cut anybody down, just sayin. I've got some serious questions coming in future posts about this whole 1000 TPS thing once I get caught up on 20 pages here. For now, riddle me this, Batman. Say we do get 1000 TPS using binary instead of JSON on a 1 Megabit per second line (and everybody who used to forge NXT a smartphone or Raspberry are pissed cause they've been cut out of the picture as slowpoke slackers). That implies each transaction is now 128 bytes so the NXT blockchain is growing at a minimum of a megabyte every 8 seconds. This is a gigabyte every 8000 seconds or roughly every 2 hours 15 minutes. That's a NXT blockchain that is growing 10 gigabytes PER DAY. The Bitcoin blockchain is currenly called "bloated" and "hard to manage" at 16 gigabytes after FIVE YEARS. So...what's the secret sauce to deal with NXT blockchain bloat of 10GB per day? I've read that our mini-blockchain can be "pruned" altho I believe I've seen that's to be a future capability. I also seem to recall that "pruning" would only need to be done annually. I ALSO seem to recall (I'm doing a lot of recalling) that the whole pruning concept was to get rid of historical transaction data. The pruning was to reset the blockchain in a cryptographically verifiable manner and say that "everybody's balances are now so-and-so at such-and-such a timestamp" and dump from the blockchain all of the historical transactions supporting that conclusion. 1000TPS for NXT requires something bordering on Harry Potter level magic. Is BCNext saying he's figured out how to PRUNE THE BLOCKCHAIN TO USER BALANCE INFO ONLY...IN REAL TIME? |

I am really interested in seeing if we can standardize on Raspberry Pis as the Official Public Node of NXT and deploy a lot of those all over the world rather than renew a bunch of more expensive VPSs that got us thru the initial late Dec crunch. I have heard different things about it - it can definitely forge blocks, it's underpowered for the task, it works better if you plug a thumb drive in the USB port to give it more memory, it needs to be replaced by a Cubie. I would like to pull all this together and come up with a definitive answer on a Raspberry config that is qualified to be a Service Node without running out of horsepower. Dave, your thoughts?
....
If we're thinking of deploying embedded servers like Rpi instead of VPS, I'd suggest we consider Odroid-U3. It's only marginally more costly than Rpi, but have far better tech specs. I've been running one for weeks and it works like a charm. Before movng to this investmemt, do we expect these devices will perform in TF with thousands of transactions per sec, with blocks being forged much more frequently than every 60 secs, etc? Realize the nework connection they will reqire as well. All the more reason to make sure it is included in a test network. |

I've been running one for weeks and it works like a charm. I'll get one on order for myself and play with it. Can it use the Raspberry Pi software setup as is or did you have to tweak it? Have you heard when large quantity orders will be allowed instead of single units? |

Does anybody know how to setup a testnet? How many servers, etc.
I might need to get one setup as early as end of next week.

This donation was around 0.07% of TwinWinNerD's current stake in NXT. That's about one NXT coin out of every thousand. If EVERY NXTer donated one out of every thousand coins in their stake, no matter how big or how small, IT WOULD MAKE A HUGE DIFFERENCE IN THE MONTHS TO COME.
Please think about it, then please do it.
ED:cut for brevity
Ricky: u blackmailing swine. I've sent 30NXT to the community fund, (tx id 11497794773844040352, my account nr below) This represents roughly one NXT per 500 in my holdings. I'm going to miss them..... I hope they'll be happy  Thanks!!! Hey, somebody's gotta be the pitchman at every carnival....for NXT, looks like it's me. Speaking of which.... You! Yeah, YOU! You're not gonna let somebody named EVILAnything donate a higher percentage of his NXT than YOU are, right? Cause YOU, dear reader, are one of GOOD guys... |

NXTcommunityfund UpdateOh I have missed this, who made it? very nice! Pin I wanted to bump the links above as now being the official way to document either your donation to or request for funding from the NXTcommunityfund. So far there have been the following donations to the NXTcommunityfund: neer.g (I think): 25,001 NXT Pouncer: 21,0861 NXT, from tech support fund Pouncer: 892,017 NXT, from software dev fund aldrin: 1,000,000 NXT A sincere thank you to all. And finally, TwinWinNerD has donated 100 NXT to the NXTcommunityfund !!! This donation was targeted as a bounty for a reddit tipbot: https://bitcointalk.org/index.php?topic=345619.msg4881794;topicseen#msg4881794This donation was around 0.07% of TwinWinNerD's current stake in NXT.

I would like to create a NXT infrastructure advisory committee from the people that had the most to do with creating the current NXT infrastructure. I think we have the structure now to properly manage the 1 million NXT from unclaimed funds to use for NXT servers and infrastructure. We can just make the 1 million NXT a directed donation toward NXT servers and infrastructure to be used over timeframe of 2 years (or tbd?)
I am first to admit I do not know how much more servers we need to properly handle 1000 TPS network. What type of servers, how many, etc. These are the sort of things that should be solved before April so we can make sure we are ready and have it in place, just in time. I expect I will just agree to the advisory committees recommendation, unless I see something totally wrong with the proposed budget.
James
I am the second to admit that I don't know etc etc but as a systems engineer I am very interested in getting involved in this. It is the critical foundation and bedrock upon which NXT must rest. And while the NXT node network may ultimately be decentralized, a good centralized committee exam of this topic up front and right now is very important. I have followed the discussion on this over the past twenty pages (drinking from the firehose) and am surprised by what I've read. CfB can offer a minimum bound on bandwidth required for 1000 TPS (1 MBS) but can't say how many NXT service nodes that can handle the full blockchain are required. Huh? That's a CRITICAL number to know. We have GOT to know how many nodes to deploy to support a particular level of service. If CfB doesn't know the answer to that question, my next question is : How do we go from here to figure it out? When I first joined this thread hundreds of pages ago, the NXT support network was just getting stood up in preparation for an expected rush of traffic expected from the initial open source release in early Jan, and there was a huge DDoS attack underway. Everybody was setting up VPSs willy-nilly. Today, a month later, we don't know how many VPSs are up, how much they cost, who is running them, and when they expire. Nobody talks about DDoS anymore so I don't know if its gone away or at a lower level or if we're now just good enough to shrug off the original attack level which is still ongoing. Inquiring minds want to know this stuff. I think James' approach of trying to define up front what is required to support 1000 TPS and make sure it exists now and in perpetuity is spot on. I am really interested in seeing if we can standardize on Raspberry Pis as the Official Public Node of NXT and deploy a lot of those all over the world rather than renew a bunch of more expensive VPSs that got us thru the initial late Dec crunch. I have heard different things about it - it can definitely forge blocks, it's underpowered for the task, it works better if you plug a thumb drive in the USB port to give it more memory, it needs to be replaced by a Cubie. I would like to pull all this together and come up with a definitive answer on a Raspberry config that is qualified to be a Service Node without running out of horsepower. Dave, your thoughts? Solar powered raspberries are a great idea but not for the critical backbone. I keep coming back over and over to the various articles about putting 32-64 Raspberries in Beowulf clusters for $1500 - $2000: http://coen.boisestate.edu/ece/files/2013/05/Creating.a.Raspberry.Pi-Based.Beowulf.Cluster_v2.pdfhttp://www.sdsc.edu/Events/ipp_webinars/2014_01_15/WagnerIPPWebinar.pdfhttp://raspberrypicloud.files.wordpress.com/2013/06/picloud.pdfhttp://meseec.ce.rit.edu/551-projects/fall2013/2-1.pdfhttp://www.southampton.ac.uk/~sjc/raspberrypi/raspberry_pi_iridis_lego_supercomputer_paper_cox_Jun2013.pdfIf we can conclusively convince ourselves that a half-dozen or so of these can secure the NXT backbone for $10000 - $15000, I think we should allocate funds to build them and get them deployed in top-secret James Bond villain underground bunkers (i.e., under BCBext's bed) as soon as possible. Or maybe schools, since Pi is an educational project - we could get a lot of mileage donating Pis to schools in exchange for them running our software... If this is a pipe dream, we need to get a consolidated VPS plan in place instead sooner rather than later. Whether we ultimately go with Pis or VPSs, we need to keep pushing to get infrastructure requirements out in the open so everybody understands the basics of them and we've got them covered. In an hour or two I'll put my treasurer hat back on and get who-donated-what updated in the forms etc... |

If someone is interested in power consumption of a RasPI-Nxt node, here is my overclocked RasPI-NXT node with optimiced clocks an voltages + wlan adaptor: <chart> Now the green peaple can calculate the power consumption of the NXT network if they would run on RasPI's Greets, eb EDIT: This is measured from wall! This is great data, thanks, some of my earlier posts pegged the Raspberry at 4W per node. So what kind of power supply are you using - just an ordinary wall transformer? |

Is this the fund for NXTcash?
I think that's a question for James, not me. NXTcash is a project he is very interested in, I think, but it is only one of many projects that would be vying for funds from this account. Alias NXTcommunityfund = NXT Account 13776816462073143763 |

Holy crap that's impressive We're just getting started. Who will donate to get us over $150,000 in available resources to support further work on NXT? How about.... YOU !?! |

rickyjames is the treasurer of the NXTfund. I will not pay any of the NXTfund to myself, nor will I even be able to touch the money.
Now that I have been entrusted with 1.525 million NXT all of a sudden I have the responsibility of deciding the best way to allocate it. It is not easy. I am still not even sure which area it is best spent on. It is super important that the funds are spent as effectively as possible.
I want to show the NXT community that the NXTfund will do its best to maximize the value of NXT and to reflect the collective will of the community. As long as there is consensus, then my job is easy. However, if there is no consensus, then I will be forced to decide the exact allocation and if I make everybody equally unhappy then that probably means I am doing a good job.

I opened a new account for the first two times with 5.10 a few hours ago. I just upgraded to 5.11 and reopened it just now to try and get the alias after James sent it some NXT. It is showing zero balance with block 55052 as the last block with a 1 hr plus gap between 55052 and 55051. Suggestions?
Post 55052 and 55051 blocks data. And pm me with the account number. 55052 16147959847405150404 1/31/2014 11:31:58 AM 34 56'919 + 51 4'451 B 2 8058897410386517129 3798658 % 55051 4598502818845733792 1/31/2014 10:19:24 AM 5 0 + 5 670 B 2 2086456349684390030 1899329 % Account number on the way via PM. It is slowly rebuilding the chain after deleting blocks and transactions files... |
