The numbers are little-endian and the hashes have their endianness reversed in relation to the hash endianness on Bitcoin Block Explorer. Here's a block that I converted previously: 01000000 version
1d8f4ec0443e1f19f305e488c1085c95de7cc3fd25e0d2c5bb5d000000000000 previous block

To run Firstbits, you need a complete copy of the block chain. Most nodes will not have a full copy in the future, so you'd have to rely on a central service.

My first coins were generated. It took less than $0.001 in electricity to generate them.

There are. BitcoinJ only does SPV, though, so it doesn't need to verify everything.

As I've said, this is not the optimal solution. I just don't want to make the major modifications to SMF necessary for a really good moderation system. I have many more interesting projects to deal with. If someone else wants to donate their time to make the modifications, let me know. Moderation is something I've thought a lot about, even before I was involved with Bitcoin. I don't much like "universal" reputation systems like those of Slashot/Reddit, and I don't like any of the existing SMF reputation mods. WoT systems are good, and I really like FMS. However, since moderation is necessary anyway for legal reasons, and non-registered users will see the one "official stream" of posts, I tend to prefer centralized moderation for centralized sites. My optimal design: A new jr. moderator position is added with no moderation ability over established posters. Newbies can post freely, but their posts are subject to more strict moderation by the many jr. moderators. All newbie posts are additionally available on a single page for review by all members for moderation/reporting.
The reporting system also needs to be enhanced, and moderation needs to be made easier.
Some restrictions also need to be increased/reduced based on post count after these changes are made. Also, bans need to be improved, there should be a way to automatically ban based on certain behavior, there should be a separate ban appeal system, etc. If I had an unlimited amount of time, I would rewrite the forum software from scratch to support all of the features I would like. |

The way Bitcoin Block Explorer detects it is by getting some previous blocks that are already in the database and seeing if they've changed.

Is anyone selling tiny computers? I'm going to use it as a router. I need a USB port and a gigabit Ethernet port. Additional built-in USB ports, Ethernet ports, PCI/PCI express ports, or built-in flash memory would be nice. No hard drives or fans.
MicroATX in a very compact case is probably the largest size I would want.

I can't believe this guy managed to post so many replies (~50) without anyone noticing that he was posting nonsense.
I can't decide whether he's an advanced bot or a master troll...

I like E4ward for temporarily email addresses: http://e4ward.com/Unfortunately, I neglected to use one of these for my MtGox registration. That's what spam filters are for, I guess. |

HTTPS might increase load too much for the server to handle.
The cookies also need to be made secure. Right now you'll send them over an insecure connection if you ever visit any HTTP page even if you use HTTPS normally.

Transferring from addresses instead of from previous outputs is more complicated, and it wouldn't allow for the scripting system.

Due to a mass of trolling, only established posters are able to post in non-newbie sections. You are considered "established" if you have spent 4 hours online and have made 5 posts. If you have really good posts, you can post a request for preemptive whitelisting in the appropriate topic. Also: - You must have made one post in order to send PMs. - You need 10 posts to put a link in your signature. - You need 50 posts to put an image in your signature. Note that it may take up to 10 minutes for your PM or posting permissions to be granted. |

A secure cryptographic hash can be truncated and still retain most of its strength, but this is not necessarily true for unhashed public keys. Possibly you'll lose more bits of strength than you would expect. It's safer to use a hash, which is designed for this.
OP_CAT is also disabled in script, while OP_HASH160 and OP_HASH256 are not.

People are now shown this helpful introductory information during registration. Should anything else be included? (This is not meant to be a complete reference, though.) Here is some important information about the forum. This is not a rulebook or agreement.
RESTRICTIONS FOR NEW MEMBERS
After registering, you will be unable to post in any section except "newbies" until you have spent some time on the forum and have published a few posts.
If you are registering to ask a question, please ask it in the newbies section. Do not wait to ask it just because you must post it in "newbies": the question is very likely to have already been asked. If you don't end up getting good responses, you can ask it again elsewhere after you are established, or you can move the entire topic.
If you are commenting on Bitcoin, use your newbie wait time to read more about Bitcoin. If you are criticizing Bitcoin, find similar criticism using the search tool to see which points have already been covered. A good use of your newbie wait time is reading Satoshi's old posts.
STAY ON TOPIC
Every reply should contain some comment that is relevant to the topic post. Do not reply *just* to another reply -- include at least some on-topic comment.
If you would like to reply just to an individual reply, you can create a new topic about it.
MOVING TOPICS
All members have the ability to move their own topics. The link is at the bottom of the topic page. Do not ask moderators to do it.
ILLEGAL SITES/TRADES
Do not post trade offers that are obviously illegal in most of the first-world countries. Do not link to or advertise sites that are built to allow such trades. |

Exactly. Thanks for the report! |

I don't see that problem with IE9.

New pages on Bitcoin Block Explorer might have some missing data for a few seconds after they are added. (This used to be fixed, but I had to un-fix it on the mirror version of BBE because it's using an older version of PostgreSQL.)

Ok so basically everybody who uses bitcoin will have to upgrade their code before 2030ish and all block headers will then start with version 2 instead of version 1?
We don't need a new block chain for that?
An upgrade will be necessary sometime before 2106. The block format will change, but the old blocks will remain valid. |

The address version of testnet is 111 instead of 0. Bitcoin sees all address versions lower than its current version as valid. So testnet sees mainnet addresses as valid.

Too tall. Too-wide signatures get a scroll bar, so that doesn't really matter.
I'm not going to give an exact number. It depends on the situation. For example, if someone always writes high-quality page-long posts, they can probably get away with a larger signature. If your signature is usually longer than your posts, then it is definitely too long.
