RGB is a second layer protocol to enable asset issuance and contracts on top of Bitcoin. The protocol leverages the paradigm of client-side validation to keep all the RGB specific transaction data off-chain, using the Bitcoin blockchain only as a commitment layer to protect from double spending. This enables greater scalability, as the blockchain usage is reduced, better privacy, as no data is visible to the blockchain observer, and more flexibility, as the protocol is not constrained by the data structure of Bitcoin transactions. I consider this a great innovation on Bitcoin as it can bring more use cases while maximising privacy and scalability, and it doesn't require any soft fork. It work on Bitcoin as is. There are already a few wallets supporting RGB that people can play with. To learn more about the protocol the best resource is https://rgb.info/ |

Per chi non lo conoscesse già RGB è un progetto per permettere l'emissione e il trasferimento di token e asset sulla blockchain di Bitcoin attraverso l'uso di smart contract off-chain. Non viene utilizzata alcuna sidechain o altre soluzioni che comportano trade-off di trust e sicurezza, ma ogni transazione avviene direttamente su Bitcoin attraverso un processo di commitment del trasferimento RGB dentro una transazione Bitcoin. Essendo costruito sopra Bitcoin è compatibile anche con il Lightning Network e con eventuali altre soluzioni di scalabilità che verranno sviluppate in futuro su Bitcoin. Per approfondire, e per riferimenti a wallet da testare, il sito di riferimento è rgb.info |

Actually the object is interesting, but will be prone to being stolen because the goods are in physical form.
I prefer digital forms online, because it's easy to access. Because the digital world will last long with the progress of the modern era.
True, but in this case I preferred to replicate the security model people are already used to with other valuables: you just have to keep it safe from thieves, and you don't have to remember passwords or mnemonics. For non-bitcoiners the main risk of losses comes from themselves, not from thieves |

€74 a piece for the Cryptosteel Capsule seems like overkill to me. I suppose you're paying for the waterproof/fireproof aspects, but as someone who already has a weatherproof safe, that seems pricey for a glorified paper wallet.
It looks pretty snazzy, though. I'll give it that.
Yeah I paid the premium more for the look than for durability concerns. Non-bitcoiners may not be able to fully appreciate a piece of paper with few words written on it, and may easily lose it within few years, so I wanted something that looked cool and that they would keep safe as if it was regular jewellery. |

It's an interesting article and experiment, but there are certainly some pretty big flaws in his arguments. If, for example, someone received today a floppy disk or a Sony minidisk from the ’90s, it would be very hard to find a device able to read it now. This is nonsense. With Amazon Prime and 10 bucks, I can have a floppy disk drive delivered to my door within 24 hours. With a car and a local computer store, I can get one within the hour. And this is a technology with is 50 years old and from a time when some houses had a single computer, maybe. We now live in time where every person, let alone every house, has multiple devices using USB - computers and all their peripherals, TVs, games consoles and peripherals, mobile phones, chargers, power banks, cars, etc. There is no way you are going to have any problem using a USB device in 20 years' time. possibly requiring the beneficiary to derive manually from the seed in order to find the keys where the coins are Again, although wallets may move on from BIP44 or BIP84, support for these will always exist. There is no way in 20 years people will have to manually derive these keys. There are far too many sites, repositories, programs, etc. out there. Only a complete failure of the internet would make every single one of these inaccessible. If storing coins for 20 years I would also choose something like steel engraving, but rather because I wouldn't want to trust that the digital hardware wasn't going to degrade in that time rather than the reasons above. Hello, the author of the article here. I agree that there will always be a way in the future to use past technology, surely you. can buy all the necessary adapters on Amazon and find some software to derived an HD seed with an out of fashion standard, but one of my design goals was to keep things simple. Today it would be annoying and time consuming to buy a floppy disk reader for a single use, and in the future it could be even worst: it's not hard to imagine a future were teenagers are totally foreign to the idea of physically connect an external storage to their device, as wireless and cloud alternatives become more popular. Obviously I may be wrong on this, the truth is that we just cannot know how consumer grade technology will evolve, so avoiding electronic devices all together seemed like the safest option to keep the redeem phase simple. Moreover writing down a key on a physical support is just more reliable for long term storage than any digital storage medium. |

Poloniex stole some shitcoin of mine over 3 months ago and there is no way I can get any reply, I think legal actions are the only solution at this point

I don`t understand this "commitment" thing those guys are talking about.What is this? Two guys are sending each other a bunch of code.It isn`t very user-friendly, i think. By the way,i don`t see the coffee purchased with this transaction delivered.  Many people have concenrns about offchain transactions security and double spending issues. Are offchain transactions secure enough? The commitments are in fact transactions that can be pushed on the blockchain in case the counterparty tries to scam you. So if you want to close tha payment channel but the other party disappears, you can broadcast the last commitment and both get the money according to the last state of the channel. If one of the parties tries to broadcast a commitment transaction that represents an older state of the channel, using the hashes and the preimages you can block him and punish him for the scam attempt. It is a different security model than Bitcoin since you have to be online to check you don't get scammed, or you have to delegate someone to monitor the blockchain for you (can be done without trust), but still it's a pretty solid security model since it is build on top of the blockchain. |

Sarebbe possibile seguire l'evento in streaming? E' stata presa in considereazione questa possibilità? Penso che sarebbero in molti come me interessati ma impossibilitati a prendervi parte fisicamente.
Ci stiamo attrezzando, lo streaming ancora non lo garantiamo ma sicuramente ci saranno i video disponibili dei giorni successivi. Nel caso riuscissimo ad attrezzarci anche per lo streaming il link sarà disponibilie dalla pagina FB dell'evento |

Bitcoin Suisse was originally a Bitcoin atm company, but recently started to offer a service where they let you participate to ICOs' pre-sales using their platform, paying a fixed fee of 100chf.
I recently used their service to join the Bancor ICO, and soon I realized they were not competent for such a delicate job. To join the pre-sale they sent me an email where they asked me to sent ETH to their address. Due to security concerns I asked they message with the eth address to be sign with PGP or some equivalent authentication method, but I received no reply at all.
When the pre-sale period was soon to be over, I decided to send the ether anyway and hope for the best.
Now that the Bancor tokens have been released, Bitcoin Suisse just disappeared. I sent to the so called "head of ICO" Nicolai Oster the ETH address where I wish to receive the tokens (PGP signed) but received no reply. I asked on twitter if they were going to give the tokens to the owners but no reply. I sent another email putting in cc everyone working in the company asking if I should consider myself scammed and still received no reply.
At this point I think Bitcoin Suisse is either extremely incompetent or just a bunch of scammer. Even if they will eventually send the tokens, I don't recommend anyone to use their service, they don't understand what it means to handle other people money and they are not qualified for the job.
Is there anybody out there who had similar experiences?
