IMO, even a soft fork is unneeded.
Just make BTC2, which transits upon, and wholly depends upon, BTC. Have the BTC2 proof-of-work depend on information in the BTC chain, and timestamp BTC2 blocks inside the BTC chain.

It appears that these changes haven't been merged yet?
The prune-unspendable is very likely to go in, and the general consensus is that OP_RETURN is the lesser of the various other more-bloat-producing solutions for timestamping data into the chain. We did not want to put in OP_RETURN without having the prune-unspendable change in first. I'm a little worried about relying on features which haven't been officially approved. What will current bitcoin implementations do with transactions using OP_RETURN - hopefully not reject them?
Most implementations today will not relay OP_RETURN transactions, meaning they will probably not be confirmed without a little extra legwork and patience. All implementations will accept OP_RETURN in mined blocks, as it is a normal and supported opcode. In practice, today, that means sending the transaction with appropriate fee attached to https://en.bitcoin.it/wiki/Free_transaction_relay_policyAfter OP_RETURN is upstream, implementations will relay OP_RETURN transactions just like any other "standard" transaction. |

OP_RETURN is the current proposal that people have been using, for adding prune-able data to the blockchain. Here is an example implementation for relaying such transactions https://github.com/bitcoin/bitcoin/pull/2738 and https://github.com/bitcoin/bitcoin/pull/2791 is the pruning piece. alt-coins and similar schemes should at a minimum produce pruneable outputs or use inputs + P2SH. The data remains available via blockchain, just not bloating the precise UTXO space. CHECKMULTISIG schemes still bloat the UTXO space (unless they are P2SH). |

This milestone was reached almost exactly one year after the company approved its 1,000th merchant.
The merchants in BitPay’s directory are diverse internationally, with approximately 50% located in North America, 25% in Europe, and 25% in the rest of the world. Ecommerce merchants account for over 90% of the business, including consumer electronics, precious metals and IT services. Bitcoin lowers the risk and cost of accepting payments in a card not-present situation, such as eCommerce.
BitPay’s merchant service continues to expand its feature set at a rapid pace. Merchants using the popular Quickbooks small business accounting software can now download and import their BitPay sales into Quickbooks.
“Our merchants are thrilled with this ability to import into Quickbooks,” says BitPay CFO Bryan Krohn. “It makes reporting their bitcoin sales just as frictionless as the payment itself.”
The month of August was another record month for BitPay, processing over 10,000 merchant transactions worth over $6.4 million. Year-to-date in 2013, over $34 million worth of bitcoins have been spent on goods and services through merchants using BitPay’s platform.
BitPay’s story is unique in the startup space. Founded by two graduates of Georgia Tech, the company built a working product, acquired customers, and achieved profitability with only the two founders.
After raising their round of seed capital, BitPay has chosen to establish their roots in Atlanta and build their company culture in a city known for innovation, but often overlooked by the SIlicon Valley insiders.
“Atlanta is a hub for financial technology, especially in the payment and merchant acquiring space,” states BitPay CEO Anthony Gallippi. “There’s a cluster of amazing companies here, focused on delivering real results through innovation.”
With pre-built plugins or embedded solutions for 20 of the most popular shopping cart platforms, adding bitcoin as a payment option to a merchant’s webstore can be done in a few minutes, without any programming code.

Now that I have upgraded to version 0.8.5, do I still need the "checklevel=2" line in my bitcoin.conf file?
Is it now safe to comment out or remove this line, or was its inclusion intended to be permanent?
You may remove checklevel=2 from your configuration. |

Is it trivial for me to modify my build of bitcoind to consider multi-sig addresses in the balance calculations?
If, and only if, you control all keys involved in a multisig transaction. Otherwise, such a transaction may be considered "partially controlled" and not really part of your "fully controlled" balance. bitcoind cannot prove that you can spend a multisig. |

Something I mentioned on IRC:
It would be nice to offer people some compensation for their shelved shares. That way, you can get paid immediately by selling your shelved shares to another buyer. Similar to selling bad debt, in the real world.
Each shelved share is worth more, the closer to the top of the stack you go. Therefore, you would want to give some indication how close to the top of the stack are the shelved shares for which you are bidding.

Warning: Please avoid using bitcoinj-based wallets, with this tool. The bitcoinj Java library does not support the P2SH feature ( BIP 16). |

BitPay has been experimenting with QR codes, scanning in low light conditions, etc.
Conclusions:
1) You want the payment protocol.
2) You want your QR code to go to a URL that will display something useful on a normal browser, or a Bitcoin Payment Request if bitcoin-aware.
3) Use a short URL for the payment URL! Critical for QR codes, in low light conditions.
4) Displays, phones, and shiny cards are sub-optimal for displaying QR codes you expect a phone to read.
5) Printed QR code, containing a short URL, is optimal. The shorter the URL -- hopefully 60 chars or less! -- the better the QR code error correction.

I tried pretty hard a couple years ago to get pools to round up their payments to non-jagged numbers like 0.01, because the highly jagged outputs they produce are bad for privacy and produce more bloaty change... and had absolutely zero luck.
Interesting. I had not thought about the privacy implications of the jagged numbers, just the bloaty change part. |

For the sake of completeness, I should mention that my upgrade on OSX 10.7.5 from the 0.8.3 version to this new 0.8.4 triggered a re-indexation of my blockchain files (OP mentioned only 0.7.2 or earlier).
Same. Unfortunately the re-index has been going on for two days. I have an i5 CPU and 8gb ram, tons of free disk space so I am really surprised it is taking this long. It looks like another day to go. Anything I can do to make this go faster? See other threads. re-run with "-checklevel=2" |

I go right down 540 when i go to raleigh.. I will stop by and take a look at it.
Yes, it is very convenient to I-540. What is up with the retention pond? is that sewage does it stink?
* edit
I see that the google maps picture was taken a couple years back during the drought.. It kinda looked like a sewage pond, but now i see it is just a regular pond.
As you discovered, it is a normal pond, not sewage. |

Great to see more wallets out there!
Curious: What is an independent and full software stack?
bitcoinj is 100% independent of bitcoind codebase, and has been deployed in the field through multibit and Bitcoin Wallet for a while.

Do you have any pictures of the land?
Yes. PM sent. |

I was raised in Raleigh and will be moving back there after my lease runs up. My dad lives off highway 98 right off of falls lake and I would like to live in that area.
Basically you want 30 k for 1.65 acres right?
Smaller lot: $33k for 1.50 acres, uncleared Larger lot: $45k for 1.69 acres, partially cleared w/ home site + septic + well How exactly do i get there? I will be in Raleigh soon and would like to drive by.
PM sent. |

Gavin or anyone else, still curious about this: Checkpoint at block 250,000 to speed up initial block downloads
and make the progress indicator when downloading more accurate. What does this mean? Does it contain or download a truncated version of the blockchain (well, the first 250K blocks) or...? See http://bitcoin.stackexchange.com/questions/1797/what-are-checkpoints |
