Bitcoin / Bitcoin Discussion / Possible solution for recovering lost Bitcoin to the "blackhole".
|

Guys,
I've already saw many threads talking about some Bitcoins that have been sent to the "Bitcoin Blackhole"...
Those Bitcoins will never back and, the person who sent them, lost money.
But, WE know that those Bitcoins are now in the Blackhole...
My proposed solution is, for example, when the last Bitcoin have been mined, I mean, when we reach 21.000.000 Bitcoins, we can measure how many Bitcoin are in the blackhole and append them to the total of Bitcoins in existance.
So, if 100.000 Bitcoins are in the black hole on the day we mined the Bitcoin number 21.000.000, we can release a new version of Bitcoin, wich will have 21.100.000 Bitcoins.
It can be done?!
I do not talking about Bitcoins lost by formated harddrive... But only those Bitcoins that was lost in the "blackhole"... The Bitcoins we all can see, in the blockchain, that are lost anyway.
Cheers!
Thiago

Alternate cryptocurrencies / Altcoin Discussion / Litecoin daemon is a godzilla in memory consumption and very slow... Why?!

Guys, My litecoind consumes a lot of memory... And it is much more slower than bitcoind and namecoind... But why?! I'm using litecoin compiled from sources, "git pull" is up to date. Look: ps xufa | grep coind
1000 16829 0.5 4.2 129724 32708 ? SLsl Jan09 6:18 /usr/lib/bitcoin/bitcoind
1000 17691 1.6 31.2 591760 238312 ? SLsl Jan09 17:58 ./litecoin/src/litecoind
1000 17694 0.3 3.0 116584 23164 ? Ssl Jan09 4:17 ./namecoin/src/namecoind
The Litecoin daemon consumes 31.2% of RAM memory! And it is very, very, veeery slow... Look: admcc@desk:~$ time ~/namecoin/src/namecoind getbalance
X.XXXXX
real 0m0.008s
user 0m0.000s
sys 0m0.004s
admcc@desk:~$ time bitcoind getbalance
X.XXXXX
real 0m0.467s
user 0m0.008s
sys 0m0.004s
admcc@desk:~$ time ~/litecoin/src/litecoind getbalance
X.XXXXX
real 8m51.580s
user 0m0.004s
sys 0m0.008s
8 minutes do getbalance from litecoind!!! WTF?! I'm using Ubuntu 11.04 32 bits. Cheers! Thiago |

Se eu acertei seu usuário na pool-x.eu, ela deve estar te pagando 137,5LTC/day. Segundo cálculos rápidos aqui, ela te pagaria 200LTC/day na simplecoin.us (desconsiderando precisões de 600LTC para 165khash/s que essa pool faz).
A pool-x.eu é a melhor quando se diz em estabilidade, como você disse, mas para maior rendimento não considero-a a melhor.
Onde tem uma calculadora p/ Litecoin? |

Bitcoin / Pools / p2pool - Decentralized, Absolutely DoS-Proof, Pool Hopping-Proof Pool [archival]

Guys!
I need some help here...
I like to setup P2Pool at my Mining Rig with: Bitcoin / Namecoin via merged mining and Litecoin.
I'm using Ubuntu 11.04 64 bits.
I already have the 3 daemons running, the bitcoind (from Ubuntu PPA), namecoind and litecoind compiled from sources.
Now I want to setup the P2Pool daemon to talk with Bitcoin (default), with Namecoin via merged mining feature and, with Litecoin.
So, how to do it?!
Do I need two P2Pool daemons? One for Bitcoin/Namecoin and another for exclusively Litecoin?!
Any tips?!
I would like to keep this as simple as possible (with KISS Principle in mind)...
The P2Pool dependencies are already installed.
Cheers!
Thiago

Got my 50 BTC back. Thanks Thiago. A+ guy
Thank you Turbor!!! I really appreciate your help!! All my bills have been payed, now I'm working to pay back to you guys. It is sad to know that I sold bitcoins @ U$3.80... But, that is the life... I'll buy more 5870 next weeks, so, I'll pay back the rest of my debt ASAP! Best! Thiago |

After that last run of refurbished cards, we're lucky to get them at $180-200 ourselves  Mmm... Okay... If you guys pay ~180-200 bucks for each 5870, can you sell it to me for ~210-250 and send it to me as a gift?! Can somebody make business with me?! Ples..Ples...Pleeease... ^^ Thanks! Thiago |

Are there any pools currently using a split pool implementation?
None that I know of. Maybe it's time to start lobbying for one. Can you provide an explanation of a "split pool"? In a nutshell, a pool which doesn't submit block headers to its miners, rather submits an address and accepts as shares any block header (with low enough hash) which credits this address in the generation transaction (with a Merkle root to prove it). The miner can either construct the block locally or get it from an unrelated getwork server. Hence the pool, which handles rewards and can reduce variance more effectively if it is large, is split from the agent responsible to decide what is being hashed. Gotcha I always called that a "smart miner" never thought of a better way to describe it. Yeah split pools are likely the best solution. It has all the advantages of a traditional pool without the risks of operator abuse. Okay! Let's build the first split pool!? I have two servers that can be used for free. I have two Dell R410 with 8G of RAM each, 3G RAM free for this. I have two Internet connections, 100M fiber and 4M dedicate line. What we need to start?! * Ubuntu Linux 64 bits 11.10; * Bitcoin 0.5.1 installed; * ? Best! Thiago |

because everyone knows your centralized architecture is much better, right? Hey, it worked for the Fed. Your users must enjoy the lottery you built in to your shitcoin. I also heard that they're stealing money from the CPF. But whatever, it's not much worse than the Fed, right?  Since you're not a programmer or network engineer you probably don't realize a few things. If you think SolidCoin is centralized then Bitcoin is even more centralized. Bitcoin has 3 pools which create 90+% of the blocks. SolidCoin has nowhere near this distribution of block creation being centralized. Game, set, match. I guess. What's your point?! The blocks are of the users of the pools. You're nonsense. |

Do you guys have a recommendation on a manufacturer? like XFX, Sapphire, etc?
It'll be my first high-end video card purchase, so I don't want to buy crappy and suffer later.
Stick with ASUS, Gigabyte, MSI, and Sapphire. The rest is second or third tier shit, especially XFX and Powercolor and Club3D. My best 5870 is a PowerColor... I have 3 of it mining @ 890fxa-gd70, 24x7, non-stop, for 5 months... |

Yeah... up to 32 x 6970s, 20 x 5870s, 6 x 5970s. Started expanding into the garage (which is where the other 40 will go).
Insanity. If someone would have told me I'd be doing this 6 months ago, I would have said they were crazy.
I envy you... Here in Brazil, each 5870 costs U$350,00. The most simple model! I must send mails to Japan ( mojostech - 5870) to try to get one as gift for U$250,00 and wait a month before start mining... And it is too risk because my country is a huge shit, at customs authorities and at all. There is only two things that I like in Brazil, regular people (friends / family / womens) and the nature... Please, if someone in U.S. could buy/send one 5870 to me, I pay U$180.00~U$200.00, if you can send it to me as a gift. I could buy at least one 5870 every 15 days. I can pay with Bitcoins! Of course!  Cheers, Thiago |

Vou começar a pensar nos FPGAs em 2013. Pois é uma tecnologia muito beta e que precisa de muito desenvolvimento.
Nessa eu concordo com o Thiago, FPGAs ainda estão muito caras, e são betas, a maioria nem tem cabeamento, só esquema de como ligar. Pra você fazer algo errado e queimar uma, não custa muito. Fora que os cara já avisam para vc refrigerar a bagaça, porque ela não tem controle de temperatura, ai vc pega uma rig desenvolvida na russia, frio pacas e traz pra goias... chance de 100% de queima. Fora as ASIC que estão falando que tem projeto, ai o preço vai ser bom, com segurança (controle de temp e tudo mais). E mais, não só as placas ainda são beta, o projeto do Bitcoin é todo beta. Tem muito especulador no mercado que ainda está caminhando para estabilização. Veja essa semana, o preço variou MUITO. Montar uma rig de placas gráficas, se falhar algo, projeto, preço, mercado... vende tudo e cata a grana de volta. A desvalorização de uma placa gráfica em 6 meses/1 ano é baixa, se vc souber comprar e vender. Agora, uma placa de mineração bitcoin, se der errado... +10 As 5870 são ótimas placas! Qualquer gamer compra no ML por 500~600 Reais fácil... E a desvalorização é bem compensada pelos Bitcoins que a placa gerou para você... |
