Nothing, probably. An "address" stored in your wallet is simply the set of keys needed to release BTC transfers from it. If someone stole a copy of your housekeys, and stole your jewelry, getting a copy of those housekeys from another safe storage location(i.e. standard bank safe deposit box) and opening your house with THOSE keys isn't going to magically restore your jewelry.

The first obvious possibility is for TCP/UDP connections over some protocol such as 802.11(commonly known as WiFi). This can be secured with simple to complex crypto so only users authorized to connect on a network can connect, so the network can't be compromised in that area.

Then, of course, there's sending the blockchain and transactions over radio without internet surrounding it. This would generally use encoding(the bitcoin protocol), error-checking(CRC32 or crypto-based MAC), and modulation. For short distances, we could get away with something like 64-QAM, falling back to simpler constellation patterns due to signal loss. In severe cases, or where it is not necessary to have high bandwidth(nodes once theyhave the blockchain), PSK can be used as it is a bit more resilient. While most PSK is at "normal" bandwidths at least in the tens of kilobits per second, PSK31 used in amateur radio is more resilient but offers bandwidth comparable to typing speed, around 10 bytes per second.  Securing it would be another challenge as there would need to be some sort of handshaking and authentication on the link. Anyone could easily interfere with this link, though, by using jammers, or badly soldered high school electronics projects that spark a bit.

This may be alleviated using highly directional antennas. With the correct set of reflectors and good aim, one can reduce the signal spread to a few degrees off center. Satellite links can also be used if one can find a satellite which will relay the data to the correct location or at least into the general internet.

So, you would save a lot of time, worry, and eyestrain(from technical documents) by using (relatively)high-distance wi-fi, or encapsulating internet protocols carrying Bitcoin packets on other radio links. Except in extreme cases, encoding the blockchain and other communication over radio is overkill, except in possibly a specialized miner setting where miners(ASICs or FPGAs) use their own radio signals to connect to a master machine. Still, it would be easier to use ethernet, USB, or WiFi.

CodeBlocks is an IDE. It uses MinGW as a compiler.

Or go out and do something that puts your back into a better position. Go swim or something.

27Mhash/sec on this "craptop" I'm stuck on while trying to replace my fried Dell XPS.

 

Hi. I am trying to remain anonymous, so there's absolutely no way I can prove to any of you I'm not a scammer, so hopefully at least someone out there trusts me. I'm seeking a 0.2BTC loan in order to invest in merged/union mining. I will pay back 0.225 bitcoins in 5 weeks.

Thanks!

By the time there is a massive increase in difficulty, there will most likely be different ASIC manufacturers, so one mass failure would affect a smaller portion of the hashing power. This portion could still be on the order of 80%, though.

I would also like to request whitelisting. I've done a good amount of mining already, and have studied a little of the Bitcoin crypto/protocol. I'd love to learn more via constructive discussion on the forum.

Seeing how this isn't legit, I'd love to see an embeddable(into a webpage) Java miner that works with existing pools, to act in the same manner as the embeddable miner offered at bitcoinplus.

I sent a PM. Hope I'm eligible!

Reading about the 51% attack, I'm understanding that it relies on the attacker generating blocks. Since hashrate USUALLY(but not 100%) corresponds to the block rate, isn't the attack success not 100% since an attacker with a marginal majority of power be often stopped by the block rate fluctuation?

Appears to work.

The system still isn't fully decentralized, though. If it was, there would need to be a sort of distributed peer tracker(akin to torrent DHT). Still, there's no true way to bootstrap without a seed node unless one were to try scanning the entire IPv4 internet for nodes.

Personally, they seem to not compete for blocks all that much, and if the miners aren't competing for the same hardware, everything looks fine. I mine on triplemining, so this might not apply to your pool.
