N1: there are several projects to create lightweight clients, that do not download the blockchain. see for example BCCAPI N2: confirmations take some time, but for small amounts at a retail store, it is safe to assume that double spends are not a problem. see also the http://www.transactionradar.com/ project. N3: yes backups are a pain. I said several times that the standard bitcoin client should either use a deterministic wallet, or have a limited set of addresses by default. if this was the case, you could backup once and for all your wallet, and not worry about it anymore. it should really be the default. |

"There are markets on DarkNet, some claim, where they sell human flesh by the pound. For Bitcoins, of course."
This is absolutely priceless.
It exposes how stupid and irrational people can be about what they do not understand.
I am definitely going to recycle that quote. I don't know what for, but I'm sure the opportunity will come.
PS: There are bidders on the Dark Net, some claim, who offered to pay one million Bitcoins for the head (or any other vital organ) of Davis Sargeant.

Is there anyway we could add to peoples forum signatures a signed link that showed what they had donated too?
such as the link in my signature ? follow the link in the image to ecdsa.org : the "comment" column of the table is where donators can leave a signed message |

the speculation subforum is where bears masqueraded as bulls talk to bulls masqueraded as bears.

I have been giving this a bit more thought. This approach requires that the bitcoin node is able to efficiently determine which transactions are associated with any incoming address, and whether the transactions are not already spent. I have not looked at the database layout of the official bitcoin client, but I doubt that the current design has been optimized for this use, we do after all have a -rescan option which takes a significant amount of time.
yes, you are right, but something like libbitcoin or ABE could do it I looked at these files. but you did not publish the server side, did you? from looking at the code, and from what you say above, it seems that your server has to keep track of the addresses and to maintain a list of accounts. This is not exactly what I had in mind. I am thinking about servers you don't have to be faithful to. |

Bitcoin is already there: "bitcoin.org - 1Q7DQVTubbUqr5by2YoZJRKCEzj9D3LQ9w" wait, this address is for the "Live Streaming Team" as they call it; not sure what it is I found this link to be more relevant: http://feedtheprotest.com/node/223 (also in my sig) |

this thread should be moved to Alternate Cryptocurrencies, the subforum that I have set to "ignore" in my preferences

This is an interesting idea! Basically this means that the client side can connect to any node in the network and let it be its proxy for creating valid transactions that the client can sign. The worst thing an evil node could do is to misinform the client about its current balance and generate transactions that are not valid/accepted by the network. Both of which can be alliveated by connecting to another node or connecting to several nodes simultaneously and compare the results.
The flipside is that the client side will have to reveal the set of bitcoin addresses belonging to its wallet. For a simple mass-market client anonymity may not be an issue, and it might even just have one key-pair.
actually I read a post by Gavin discussing that, but I can't find where it is. the client does not have to reveal the set of bitcoin addresses to a single server; he could use a different server for each address. btw, I downloaded your java code; is the protocol documented somewhere? |

Here is a new service that allows you to annotate the blockchain addresses that you own, or the transactions that you made. link : http://ecdsa.org/annotateOnly you can annotate your addresses and transactions, because annotations are signed with your private key. For example, if you donate to a charity of fundraiser, you can now add a message showing who you are. This service uses the new "signmessage", "verifymessage" commands of bitcoind, available in bitcoin 0.5rc1 ( https://bitcointalk.org/index.php?topic=47586.0) |

edit:please note that the syntax for counters has changed. the new syntax is: http://ecdsa.org/counter/1EUqkFmL9HNpBRvbWRAqCiUjepaR7Vbryp |

Normal people dont even use the client, they use an online wallet service. The client is for geeks.  I think the future of bitcoin is dependent on making lightweight clients. I am glad to see developement moving that direction. There is one (possibly two) lightweight android clients in the works implemented on top of the BCCAPI. I am very confident that this is the secure way for Bitcoin to his the mass-market. We are talking about clients that are installed and fully functional within minutes, without no risk of the server side going renegade and stealing coins. I agree, this is the way to go. ideally, the server-side of this BCCAPI should be performed by any node of the bitcoin network. |

heh, the first thread was started by me. thank you for bumping it regularly. It is true that there is a lot of noise in the let's rip off the newbies alternative cryptocurrencies subforum. I found that the best thing to do is to just ignore this subforum. |

i should warn people, DO NOT TRY TO MAKE THESE AND PASS THEM OFF AS BITCOIN CURRENCY.
it is a federal crime to do so because it looks like federal reserve notes.
It should be a crime for money to be such an ugly green in the first place. You both are right. If you print it on paper, I suggest to remap colors first, replacing green with blue or pink. It will be both legal and cute. |

not sure if this is the right place to post it; I didn't find any subforum for bitcoin art.  sorry about jpeg compression. The text on the left is: "This currency is not issued by debt, neither public nor private" hi-res version: http://bitcointimes.tumblr.com/post/11246451688 (click on the image from there) |

"Bitcoin: a Ponzi scheme since 2009"
Note: of course this is sarcastic. A characteristic feature of Ponzi schemes is that they cannot last for a long time; reminding people that Bitcoin has been around for almost 3 years should make the contradiction clear.
ok, less sarcastic version:
"Bitcoin: called a Ponzi scheme since 2009"
