Ahora mismo la relación beneficio/riesgo al aceptar bitcoin mediante BitPay es... infinito!
Por no tener, no tienen ni que tocar los bitcoins, ni llevar contabilidad especial, ni tener que lidiar con el aspecto legal, ni tener problemas con la volatilidad... Y lo más importante, 0% de fraude. Ningún otro método ofrece más por menos.
A partir de ahora el que no acepte bitcoin es porque no quiere (o no conoce todavía).
Solo me falta saber una cosa que probablemente alguien que tenga mas experiencia con Bitpay sabrá: ¿Vale dinero la transferencia de Bitpay a tu cuenta de banco? Por ejemplo las SEPA valen algo, no se cuanto pero poco. Es decir, si pago 100€ en bitcoin, lo convierten a EUR, 100€ pero luego al enviarlo a la cuenta de banco del restaurante no se si cobra comision aunque sea el banco por la transferencia o algo. Si es transferencia SEPA será menos de dos euros por transferencia. Si hacen una transferencia diaria (que tal vez pueda que no tenga que ser tan frecuente), sería de 2 euros al día. Y tecnicamente no sería BitPay quien cobrase por la transferencia, sino el banco. Sea como sea, Bitcoin se está transformando en una forma de pago muy competitiva. Estoy leyendo y hacen una al mes (si superas los 20€ en ventas), de todos modos he preguntado al soporte, igual hasta pagan ellos los 2€ de la transferencia SEPA. Edito: Creo que en varios bancos en España son gratis las SEPA (enviarlas, recibir siempre es gratis), lo mas probable es que BitPay use un banco que salga gratis enviar. |

Justo iba a ponerlo aquí. RESUMEN De cobrar el típico 1% en cada compra Bitpay pasa a cobrar 0%, a los negocios les costará 0 aceptar Bitcoin. En cambio si quieres soporte telefónico, integración en tu carro de compras personalizado o POS puedes pagar un extra pero la mayoria de tiendas no necesitan esto. Por ejemplo todas las tiendas de CALLE BITCOIN pasan a funcionar al 0%, sin cuotas al mes ni nada por usar BitPay. |

Otra cosa, Blockchain.info está haciendo un mapa verificando todos los sitios que usen Bitcoin, en España actualmente hay 0 sitios, he preguntado y me han dado este formulario: https://docs.google.com/a/blockchain.info/forms/d/1gMykEdCC2TqGYNId9_NNyW0vExTBszaFFV5XhPmTkpg/Objetivo: añadir todos los comercios de #CalleBitcoin a este directorio (En la app de Android de Blockchain sale este mapa). De momento he metido el Do Eat! y Check in Madrid al mapa, a ver si lo aprueban. Por cierto, por cada local que incluyais a este mapa recompensan con 0.001 BTC (45 centimos de euro) siempre que sea información real y el local exista y acepte bitcoin. Si alguien se pone a agregar locales pido que lo haga de forma ordenada, correcta y que ponga aquí cuales va poniendo así no hacemos uno dos veces.  |

Sobre el tema de la legalidad que habéis mencionado creo que puedo aportar lo que hasta ahora entiendo de la legalidad en España: - Si usas Bitpay, Coinbase o similar para convertir bitcoins en tiempo real estás cobrando en euros por lo tanto no existe ningún problema, haces las facturas en euros, el IVA en euros y cobras en euros. No hay ninguna limitación.
- Si el negocio cobra en Bitcoin directamente (para dentro de unos dias convertirlo o no a euros) tienes un límite de 2500 euros por factura como ya pasa con el dinero físico, esto no es problema para bares o restaurantes ya que ningún cliente llega a este límite. Por otra parte no hay ninguna regulación vigente más para aceptar Bitcoin, la factura se hace en euros, se calcula el IVA en euros y luego debajo por ejemplo puedes apuntar que se ha pagado en bitcoin y la cantidad, pero se declara todo en euros.
Si quereis podeis poner aquí las dudas que vayan surgiendo y entre todos podemos ayudar. Respecto a #Callebitcoin querría saber que procesadores de pago suelen elegir los comercios, veo que tanto BitPay como Coinbase son patrocinadores, ¿Es posible usar Coinbase en España (para recibir euros en tu cuenta bancaria cuando te paguen) o la unica forma es BitPay (que si que se que opera en España)? Como siempre gracias por el esfuerzo y la gran iniciativa, saludos a todos los integrantes del proyecto. |

Hola RME, en realidad el CEO de Heyplease contestó a mi intento de contacto por LinkedIn, fue bastante educado pero me escribió que no lo van a considerar antes de 6 meses por otras prioridades. Quizás si escuchan por otros canales que más y más negocios se apuntan a la iniciativa, ¿se interesen antes?
En realidad me refería no a HeyPlease sino directamente a CAFE & TE, la cadena de bares (que usan HeyPlease). Es decir, ya que Cafe & Te ha aceptado usar HeyPlease igual se les puede convencer de que también usen Bitcoin. |

Viendo el video he buscado lo de heyplease y parece que la mayoría de comercios que lo aceptan son de la cadena CAFE & TE. Podríais intentar hablar con ellos, tienen por lo menos 20 locales en Madrid, si lo conseguís serían 20 de vez. http://www.cafeandte.com/restaurante/restauranteList |

The thing is making getblocktemplate (or similar) easier for miners so they can set it up as fast as stratum one.
Then the Bitcoin Foundation or the core devs or some people that have influence should try to contact the main pools to make them aggree some rules (Use this brand new protocol that is better, gradually remove the other because is centralised, do not ever reach 30% or more hashrate or you will be considerated as harmfull)
This way soon pools should start showing in their websites "This pool agreess the Fair Mining Treaty and it uses getblocktemplate".
Then if this is done the right way (most of pools join this, the new protocol is faster...) most miners that are in public pools should use it, then we tell miner software developers to deprecate the old protocol because is centralised and also only few miners use it. Finally we tell Pool Owners that they need to remove the old protocol. They do it and we are fine.
I know that this sounds difficult but we should work to improve protocols that let the individual miner to choose the transactions they want to include, this way the pool owner has no word to say about double spendings, mining other chain, etc.
But pool owners should still decide things like "minimum fee to include in a block", "coinbase", "max size of a block (and why not, minimum size)".

ssl , by firefox..it is free
What are you meaning?  |
|
|

StartSSL is good for starters, but I wouldn't recommend it long term. It's root certificate isn't fully trusted on all browsers. So you'll likely get the little yellow warning, which can make people think it's not trusted. I know on Firefox you can't browse a site with StartSSL unless you add its root authority to the certificate store manually. The free version has no validation or verification at all. Any scammer can get one, this is why it's not trusted fully.
Nope, works perfectly with firefox, I use it in some websites. Also the verification is done with an email to webmaster@domain just like everyone else do (I mean cheap certificates, 30$ or less). |

In the Bitcoin community we love crypto, that also includes loving https, bitcointalk.org, blockchain.info, bitstamp.net, bitcoin.org, all of them are using HTTPS right now. Now you can also get a SSL certificate for your website for free (Yes, free as a free beer, forever) going to https://startssl.orgTo setup and install it for free I recommend reading this tutorial: # How To Set Up Apache with a Free Signed SSL Certificate-> https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-with-a-free-signed-ssl-certificate-on-a-vpsNote: it does not matter your provider, you dont need a server at digitalocean, it works in any Dedicated Server or VPSNow that you have HTTPS in your website you should redirect http:// to https:// using this code in your .htaccessRewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L] Also if you want enable HSTS to avoid SSLstrip attacks including this code in your .htaccess: Header set Strict-Transport-Security "max-age=31536000" env=HTTPS |

I did it in Photoshop so I could not export it to SVG,
Make it as a path and export as EPS or an Illustrator file. Using Photoshop is not an excuse to not follow best practice. EDITNot trying to be an idiot here, but learning to choose the right tool for the job is one of the first things one should do when venturing into a new field. the original image was a screen grab from a video.. so that makes the original file (source) bitmap.. the OP simply enlarged it and then cleaned it up and smoothed the edges. and thats all he done. be greatful for anything someone does he(rme) was not paid, commissioned or bountied to do it so i see no reason that you should make demands of him to put it into a special format for you.its still a bitmap in the same format that he grabbed it (screen print button on pc). now if you want special formatting, maybe it is best you use his file and convert it yourself.. and by the way your not an idiot you (bananacontrol) are trying to act like a know-it-all, but not a do-it all. I'm sorry that you misunderstood my intentions. It was merely an attempt at challenging OP to learn a little about the basics of the field he is dipping his toes into. Definely working with vectors is a really good thing but I have not yet started using them. As a personal challenge I will try to do a vector by myself. |

Hey bro can I use it ?
I'm thinking about using it on the backside it will look something like this.
FRONT:-
REAR:-
If you don't have any problems with it I'll soon launch a campaign and will see if anyone wants it.
Yes, everyone can use it. |

It is already possible with getblocktemplate and it would be trivial for stratum to add similar support. However no pools care, no miners care. The reality is most miners know it is bad (if only for perception) that a single pool has so much hashrate. They could easily move to another pool. It would take all of 5 minutes of work. They don't care enough to do that. What makes you think the same people who can't be bothered to use another pool, or use p2pool would instead generate their own transaction sets (requires running a full node)? They won't. This is a human problem not a technological one.
I believe that getblocktemplate is slower and needs a full node running. Im talking about a new protocol that works as a SPV (asking for transactions to random nodes in the network) that is fast and does not penalice the miner. |

We all know the recent news, Ghash pool controlling 51% of the hashrate. While some consider it a threat others think that is not harmful.
The thing is that we have to do something to stop this from happening again.
My proposal is to start thinking about miners that join a pool like independent miners and not slave miners, this includes creating a new mining protocol that does not rely on the pool sending the list of transactions to include in a block. Each individual miner has to collect transactions by his own and mine that, this can be achieved by running a full node or by running a SPV like node that ask other nodes for transactions.
Once this protocol is developed and standarised we as a community could require all pools to use it (because its better, because is more trustless...), not by imposing it but by recommending it.
Pool owners could send some instructions using this protocol to the miner about how many transactions to include per block (some pools want small blocks), how many 0 fee transactions to include, how much is the minimum fee per Kb to include transactions and some info about the Coinbase field in the block.
This way is impossible to perform some of the possible 51% attacks:
A pool owner cant mine a new chain (selfish mining) (pool clients have a SPV or full node that has checkpoints and ask other peers about the length of the chain)
A pool owner can't perform double spends or reverse transactions (pool clients know all the transactions relayed to the network, they know if they are already included on a block)
A pool owner cant decide which transactions not to include (but they can configure the minimum fee).
A pool owner cant get all the rewards by avoiding other pools from mining blocks (Because the pool client knows the last block independently that is from his pool or other).
The only thing that a 51% pool owner can do is to shut down his pool and drop the hashrate by 51% because he does not control the miners.
If the pool owner owns all the hardware in the pool my proposal is not valid, if the pool clients dont use this protocol my proposal is not valid.
I want to know if this is possible or its been developed or there is already a working protocol that works like this, also I want to read other people's ways to address this threat, thanks for reading.

Look at the T-shirt, looks great:  |

Great work. Just out of curiosity: did you intentionally make the outer circles non-concentric? (to ehhr... reflect the "decentralized" nature of Bitcoin? ha ha)
Yes, this way looks like a actual coin and not like just some circles. A bitmap data file at 4096px?!! Why on earth not just make a vector file?
I did it in Photoshop so I could not export it to SVG, but a reddit user has made a vector version here: http://amgic.adultponyfinder.com/bitcoinLogo.svg |
