What is this about?
I’m looking for an opensource crypto-currency exchange engine.
My preference would be for something easy to use like joomla or drupal. My exchange setup needs support for alt-coins and bitcoin.
I have discovered intersango myself. However, sql file is corrupted, there is no creation of tables and import does not work. Plus it is bitcoin exchange only (and I need alt-coin support). Site of this exchange with “invites only”, registration is closed.
Is there something super-simple that I can use to get started?
Of course, the function of mining is to secure the blockchain, but I’m looking for a more abstract summary of what the exact problem is that mining tries to solve? I believe its called the Byzantine Generals problem, but can it be described in a couple of sentences?
The network needs to select one random stranger out of a large group at a fixed schedule, and uses a ‘hashing-lottery’ as a reasonably fair method to do so. Is that a good definition of the reason why POW is needed?
In other words: Suppose I developed an alternative method to select a random p2p node every few minutes, who gets to publish the next block, could that replace cpu-based proof of work?
