As I understand it, currency creation is fundamentally metered by TIME - and if that is the fundamental controlling variable, what is the need for everyone to "roll as many dice as posible" within that given time period? The "chain of proof" for coin ownership and transactions doesn't depend on the method for spawning coins. <br/></div><br/>You seem to have things backwards.<br/>The "dice rolling" is to maintain the "chain of proof".<br/>Actually giving out the coins is a side effect.<br/><br/>I have 2 questions for you: <br/><br/>Without high computational burden how do you propose we:<br/><br/>a) Maintain the integrity of the system?<br/>b) Distribute/Seed the system with coins?<br/><br/></div>I understand that the incredibly thermodynamic inefficiency I was complaining about is in fact very deliberate, and bitcoin might be said to waste as much energy as possible, as a security feature! Now I really don't know what to think - because exactly what I was complaining about gives the system its diabolical effectiveness. I think my earlier analogy with deliberately burning wheat and trading photographs of the ruined crops is very apt. We are all ceremonially burning computer cycles as an investment of resources in a "trust pool". The irreversibility of the process - the fact that we are burning our computational wheat crop just to crank out unusually numerically small hashes - is definitely perverse, and deliberately so. The entirely stupid amount of resources wasted minting bitcoins makes it nigh-impossible that anyone would choose to be EVEN STUPIDER as to waste the amount of resources necessary to outcompute you.<br/><br/>The problem is, if you look at the competition in the world of digital currencies - online casino currencies, mmorpg currencies, and the like - they often have much larger economies than bitcoin, with much less security, verifiability, and certainly much lower thermodynamic burden! The market, in the form of consumers, does not seem to demand a massive investment of random numbers to be willing to trade in a currency. I understand of course that the competition is generally centralized and that the thermodynamics of bitcoin are designed as a substitute for central authority - but I personally would regard a "large enough" network of nodes signing a transaction history using standard public key cryptography to be secure enough to use without demanding to see photographs of 500 billion bushels of burnt wheat as proof of the network's seriousness.<br/><br/>I see three additional replies written while I was typing this, so I'll try to refocus:<br/><br/>I understand the system, and appreciate its strengths. I am actually happy to participate in the bitcoin economy, sending coins around as tips for forum posts and the like is enjoyable as a "game" and the cost of entry is currently pretty low. My personal concern is not over botnets taking over with forged currency, but with botnets taking over the issuance of genuine coins. That is why I think the "security through wasting energy" concept is flawed - not because it isn't secure, but because it has the potential to create incentives for harmful behaviors, which in turn diminishes the likelihood of building social trust in the currency.</div> text/html
