I'm wondering about the invisible wall at 6... the psychological one

Why does the network need to rely on "trusted nodes"
What's wrong with just "nodes"? Anyone can be a node, that's part of the point. Once we get to the point where people mostly use lightweight clients, a client which wants the whole blockchain can keep connecting to nodes and asking for a list of peers until it finds one with the whole blockchain, or half, or whatever. It starts downloading from that one while looking for more peers to verify against. The concept of a "trusted node" is antithetical to Bitcoin's goals.

Exactly. What's that Satoshi quote? That governments are good at cutting off the heads of things like Napster? Well... how many trusted nodes are we talking about, who's going to protect their heads, and how do I apply to be a trusted node so that I can mess with the blockchain later on?

I'll pay up at least...

Well, it's the official client for one.
For two, the more people that stop using a "full" client, the fewer full client nodes we have, and the less secure the network is.

Deprioritizing sounds like a horrible idea. Who gets to decide who to limit?

Maybe 25 GiB/year isn't too much storage-wise, but it is way too much bandwidth-wise.

"Hey have you heard about Bitcoin?" "Yeah, last month" "Why aren't you using it? I find great deals every day on BitMit" "Blockchain's still downloading"

  right...

The size of the blockchain will soon be a huge hindrance to widespread adoption

Genious! Create an account just to get the 10 mBTC!

They need to fly by "pulling themselves up by their bootstraps"... its the joke from which the term "bootstrap" as a verb originates.

Buy a mac laptop for the hardware, then remove the OS
Or buy an ASUS...

Chicken, egg, meet bootstrap. Now fly!

Yes, it is something like that.

I don't like the idea of disposable PVC cards... think what it would be like to throw away your credit card after every grocery-shopping trip!

re-statement:
Instead, having the merchant empty one of your wallets and send to the other would be ideal: he can't access the one he sends the change to. A bitcoind on your home computer would then refill the public address.

Another way of doing it, with the home-hosted bitcoind:
Have a public address 1CUST with a very small amount (~0.01 BTC). The merchant then charges a number of Satoshis from that to 1MERCH. The home-script sees this transaction. It multiplies the satoshis by some number (10,000?) and sends that amount to 1MERCH.


Both of these methods have a problem. They avoid giving out your main private key but:
1. With this method, the merchant could set up a program to rob your address as soon as it is filled back up
2. With this method, the merchant could charge the whole 0.01 BTC, causing your script to send 100 BTC to the merchant. You throw away the card, but the damage is done.

So really, I'm not seeing a viable way to make re-usable PVC bitcoin cards, given that there's no way short of rubber-hose cryptography to prove that someone owns such-and-such an address.

I see a simple method which could work for one reusable card. It would make stealing instantly detectable, at which case you punch out the merchant

The card has 2 QR codes on it, but they are not of the same address. Here's how it would work:

• There are 2 addresses, 1a and 1b.
• The public address for 1a is shown, as is its QR code.
• The privkey for 1b is shown, along with a QR code which scans to it.
• To "load" the card, send bitcoins to 1b.
• When the merchant takes payment, he transfers *all* of the money in 1b to his address, then sends the "change" to 1a. The merchant cannot take more money now, because he doesn't have the 1a privkey.
• Finally, in order to re-use the card, the change must be sent from 1a back to 1b. This could be done by bitcoind and a script running on your home computer.

Now the only possibility for stealing is when the merchant doesn't send you the change. But since anyone can check the blockchain from websites like blockexplorer and blockchain.info, this isn't a feasible attack. You'd notice he overcharged, and demand your money back. Then you could sue him or punch him out if he didn't.

At this point we just need to sit back and let the invisible hand sort it out. If everybody stops doing the tasks which pay 0.67 cents (new low... saw it just now), then the tasks will need to pay more...

At this point, though, there might be enough people who are 20 cents away from the cashout that this takes a while. Or, there might be enough people content with working for 20 cents / hour that the service keeps running...

Yeah, I saw one worth 0.75 cents the other day... who the hell would do a page of work for less than a cent
You'll do better walking along the highway and picking up bottles for their 5 cent deposit.

OK, thanks for answering.

Sometimes I want to send more than 0.0005 tx fee, because the tx is very large. Unfortunately, there's no way to change it, so I have to wait for several hours before Eclipse-MC finds a block. Please add functionality to control fees.

The top buttons don't display a "hand" cursor when you mouse over them. In fact, they show a text-selection "I" cursor. They used to be on one line. They're less round.
Notice how oddly the words wrap here:

they didn't do that before.

Or I'm crazy...

I want to be able to ignore the fixed-rate mining bonds... they flood the market

lol, 10,000 days of ad space?
