Por lo poco que se de temas más técnicos, esto que mencionas no sigue siendo un "ataque del 51%"? Leí hace unas semanas que en Bitcoin Cash (creo) tuvieron una situación parecida: un hacker consiguió robar una cantidad enorme de fondos (creo que de un exchange); pero por un acuerdo entre los mineros, revirtieron la transacción. Buscaré el enlace, pero no tengo demasiadas eseperanzas...Pensandolo un poco más; el doble gasto no es otro modo de "hacer la transacción reversible"?
Ha habido suerte; el enlace interno del foro es el siguiente: https://bitcointalk.org/index.php?topic=5147140.0 |

Local / Primeros pasos y ayuda / Creando un nodo de Bitcoin Core y LN
|
on: July 01, 2019, 09:31:42 AM
|
Como ayer comentaba aquí, me estoy planteando seriamente ejecutar un nodo doble en casa para Core y LN. No he podido investigar tanto como me gustaría, ya que mi tiempo está bastante limitado entre mi hilo de hardware wallets y mis actividades fuera del foro. Sin embargo, gracias al foro en ingles, he podido llegar a diferentes conclusiones (y precios). En un primer momento, me plantee utilizar una tarjeta flash de 256GB para ejecutar el nodo, pero tenia ciertas limitaciones: si bien el precio era asequible (12.5€), las tarjetas flash puede gallar de maneras bastante irreparables, y como se me comento en el hilo de Lightning Network FAQ, tampoco son unidades preparadas para estar en constate ciclo de leer-escribir datos. Descartada esa opción, he tenido la suerte de encontrar un disco duro de 1TB SATA 3 en wallapop por la friolera de 20€  . Ese disco será el que utilizaré para almacenar el SO y la blockchain; y ahora paso a las distintas configuraciones de hardware que tengo disponibles:
En primer lugar, tengo la posibilidad de utilizar una Raspberry Pi 3B+; junto con un estuche y su sistema de alimentación. La placa vale 36€ en amazon, y el estuche ronda los 6/7. El precio del disco duro se mantiene constante en todos los casos, y da la casualidad de que tengo un adaptador SATA-USB por casa (varios a decir verdad). El único problema, es que el que tengo libre utiliza el protocolo USB 2.0 en lugar de 3.0; con lo que conseguiría velocidades menores a la hora de leer-escribir datos.
Como se me comentó en el hilo de LN FAQ, sería más productivo que en lugar de un Raspberry Pi 3 utilizase una 4; ya sea de 2 o de 4 GB de ram. La Raspberr Pi 4 de 4Gb ya tiene un precio más elevado (58.95) y la de 2GB es solo 10€ más barata (así que por la diferencia, descartamos). La caja es un poco más barata, estando en 6€ pero no incluye cable de alimentación, por lo que habría que desembolsar otros 8.50 (y 5 de gastos de envió). además, como el adaptador que tengo solo es USB 2.0, sería conveniente que tuviese uno de 3.0 (rondaran los 15/20€ pero no es una prioridad).
Por lo que ahora mismo tengo 2 situaciones sobre las que estoy reflexionando: - Coger la Rasp 3, gastarme 40€ (+ 20 del disco) y montarla con lo puesto, ir viendo como avanza la cosa y en función de eso hacer un upgrade al hardware (que ya habrá bajado el precio para entonces)
- Coger directamente la Rasp 4 de 4GB; hacer un desembolso más grande en primer lugar; unos 78,38€ siendo exactos (disco y adaptador de disco aparte; 40€ aprox). La red se va a beneficiar más, y tendría la posibilidad de abrir más canales de LN (al tener más ram) y con el dust que se genera como comisión de LN ir recuperando poco a poco
- También dispongo de un disco duro de 360GB (blockchain cabría perfectamente), y el adaptador de ese si que soporta USB 3.0, por lo que sería posible implementarlo en ambas configuraciones
Posiblemente acabe haciendo la segunda; aunque hasta mediados de Julio no habrá re-stock en la tienda online que he mirado (así que hay tiempo para darle vueltas). Escucho opiniones sobre que setup utilizaría cada uno  Lo he puesto en Primeros pasos y ayuda, ya que una vez configurados los nodos supongo que se podrá utilizar como guía tanto de pasos como de precios para cualquiera que esté interesado en hacer lo miso |

Just FYI, Trezor uses something of a proprietary method of signing messages using P2SH addresses. I'm not sure if any other wallet is able to replicate this. I believe the method is published, just there is no accepted "standard" as yet. Much like Electrum and "bc1" addresses.
Hmmm, that's odd, I got another one staked a couple of weeks ago and there was no issue. But anyway, thanks for the info |

Unable to verify... what wallet/sig generator did you use to create that signature using a P2SH address?  The tool to verify/sign on trezor.io website |

Raspberry Pi 4's CPU is much faster than 3B+'s. 1 GB version seems to be priced the same as the third model, at least in my country. If I were you, I would buy 2 GB or 4GB model of Raspberry Pi 4 and HDD rather than 3B+ and SSD. The fourth model has USB 3.0 and gigabit Ethernet unlike previous models. Buy a small SD card only for the OS, either 8 GB or 16 GB one.
Fair enough; difference seems to be of around 20€ using a 1TB HDD and a 2GB pi 4B and 30 if raspberry of 4G. I'll give it some thought while I wait for the retailer to restock (looks like mid-July  ) and if I happen to come accross any more doubts; I'll try to get them solved! Thanks for the help!
Edit: Just realized that supply cable was not included; price has gone up a bit to around 80€ on Raspberry 4 4Gb without the HDD, against 40€ of Raspberry 3 |

What node are you reffering to? Bitcoin Core? If so, then the answer is yes. Lightning Network node? You don't have to open channels but then such node doesn't do anything. In order to route payments, you have to open quite a lot of channels.
Understood, thanks! Raspberry Pi 3B+ is enough to handle Bitcoin Core and Lightning Network node (LND recommended). However, I would recommend you to synchronise with the Bitcoin network on your computer and then copy blockchain data to an external hard drive. Don't use 256 GB memory card. Most of such cards are not designed to handle constant reads and writes. If you haven't bought that model of Raspberry Pi yet then consider buying the latest model (4B) with some extra RAM.
I have not bought yet the hardware, but my budget is quite limited. I had thought about the flash card being a problem; and the only feasible solution I could find to that is to use an external HDD (or even SSD) rather than a flash card, connected on USB. |

y es por esto que lo que necesitamos son mas exchanges del tipo onchain, no se si alguien de ustedes llego a usar shapeshift, pero en dicho exchange uno enviaba una moneda y recibía otra (Por ejemplo, mandas doge y te devuelven LTC). Creo que es el modelo de intercambio mas seguro tanto para los clientes como para la misma casa de cambio. Una lastima que se pusieron muy pesados con el tema de registro en la pagina. Sin embargo podemos usar sus servicios sin registrarnos a través de la cartera Atom.
No opera Etherdelta de la misma manera? (ya se que es para token ERC-20) |

I've reading trough the forum and some googling; because I'm considering opening a LN node with a raspberry, but there are some concerns I have and haven't really found any useful info out there (maybe I should have look further). Questions are the following: - Would I be able to run a dual node on the raspberry? (BTC+LN)
- I understand that to run a node you don't need to have an open channel; am I right?
I'm sorry to ask if this has been answered before. Thanks in advance
I'll give some more details, as I believe that will help resolve the doubts. I'm planing on using a Raspberry PI 3 Model B+ plugged straight to the router, and with a 256gb flash card for the OS (Raspbian). Then I'll be using the Core client, then things start getting a bit fuzzy for me; I'll use Lightning Network Daemon, then some port forwarding on the router and finally create an automatic reboot with a backup (I believe that's the order for everything) |

btw ur trust record isnt any better tho  I have to disagree, my only "negative" thing is a neutral feedback for a trolling to a "likely scammer" that went a bit sideways in the end. Now, let's get back on topic; you say you have DOGE, please state how much DOGE you have |

why cant u just but it directly from an exchange?
Exchanges are centralized, have fees and most of them want to know who you are either go first or use an escrow ...
You are some funny guy asking to send first with a solid -4 trust, having woken up from a period of inactivity recently at least you consider the posibility of escrow.... |

It seems that i cant send you PMS any more, the forum notification says to buy copper membership.
The amount that i can repay is 0.018 BTC. The lending amount is 0.015 BTC
Yeah, there is some kind of restriction to low rank members... Alright; once Darkstar_ gives you his address so that you can send the collateral, and okays me I'll send you the 0.015 BTC. That leaves you 10 days (until July 9th), to repay 0.018 BTC I think that sums up everything? |
