Uiteraard.

Heb goudstaaf van één kilo (Tony Goetz) als investering die ik wil omzetten naar Bitcoin. Prijs volgens dagkoers goud en Bitstamp. Op dit moment is dit 65,6 BTC. Omgeving Antwerpen.

What would the objections be to implement a captcha mechanism in the mining process in order to protect the network from centralization of mining power?
We could for instance say that a captcha should be filled out every time a worker produces a week's worth of hashes on a standard AMD GPU. The captcha should be part of the hash challenge mechanism so that pool operators would be excluded from being able to fill in one global captcha only when they find a block. This means that exclusive p2p mining should be inherent to the protocol.

The first thing that comes to mind is that people with big mining operations would just hire cheap labor to fill in the captchas. This, however, would make mining more expensive for big operators. For small operators it would just represent a minor nuisance.

Could this work?

Hi fellow bitcoiners,

Can't believe this is my first post on the forum, seeing it has been a year since I first discovered The Light through a local financial newspaper. Like most of you, I immediately was mesmerized by the concept and spent the following weeks studying everything there was to know about Bitcoin. I was basically living and breathing Bitcoin for the next few months. I went to many Bitcoin meetups, organized a local exchange meetup, built a Litecoin rig with two 7950 GPUs and am now looking to start a Bitcoin Academy - a physical place where people can come learn about cryptocurrencies - in the open source spirit.

This last year of intense Bitcoin study has led me to conclude that Bitcoin is only the first of a wave of decentralized apps that are likely to revolutionize the way we interact. These are applications that we can expect to see in the following years:
Decentralized:
- exchanges for digital assets
- notary ledgers
- marketplaces
- social networks

I'm looking forward to 2014, a huge year for BTC.

Cheers,
David.
