"Something I only recently realised is that Satoshi's apparent policy(1) of never making any cryptographically secure signatures to link together his posts - or indeed any communication at all - fits well with the avoidance of creating a central authority figure. ... As you've often said, the biggest achievement by Satoshi in the creation of Bitcoin was to create a system where the identity of the creator is a mere historical footnote. We can probably go further, and state that while doing so, Satoshi quite counter-intuitively took steps to avoid even creating a pseudoanonymous identity." - Peter Todd, https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015...
And of course, the most important sentence is from Satoshi's message itself:
"Bitcoin was designed to be protected from the influence of charismatic leaders, even if their name is Gavin Andresen, Barack Obama, or Satoshi Nakamoto."
So whether it's Satoshi or not, it doesn't matter; Bitcoin was intended to transcend even Satoshi's own influence.
In the interviews I do, I tell the candidate that:
1. There is no time pressure. Work at a normal pace, as if you were working here. This is not a speed test. I don't expect you to finish. I mainly want to know how you think.
2. You should look things up. Behave the same way you would when coding at home. Use Google, Stack Overflow, documentation, etc.
This probably works better for the interviews I give because the problem is not implementing an existing algorithm. It's a realistic task, something that we've actually built on-the-job.
Technically, Bitcoin transactions are not anonymous; they're typically pseudonymous. Braintree requires buyers to use a Coinbase wallet. There are many reasons for this, but refunds is one of them. We enable merchants to easily issue refunds and have a cohesive experience in the Braintree Control Panel, with bitcoin alongside other payment methods like credit cards, Venmo, and Apple Pay. Feel free to contact me if you have any questions.
1) ASICs. In the early days of Bitcoin, one of the biggest concerns was: "Now that computational power is worth real money, aren't malicious hackers going to become rich and powerful by harnessing botnets? And more normal people's computers will join botnets as hackers are directly incentivized, by bitcoin mining, to exploit users more often."
With the rise of the Bitcoin-specific ASIC, that suddenly became a total non-issue. It's completely worthless for a normal desktop PC to mine for bitcoins now: their total computational power, as measured in SHA256 hashes per second, is a tiny drop in the ocean compared to the high-end ASICs that are mining today.
Problem solved.
Though governments will try to get involved, and no one can definitively predict the winner in advance -- I believe it's most likely that private industry, incentivized by Bitcoin's mining rewards, will create the most advanced specialized chips for Bitcoin. They're already pushing much lower nanometer processes than general purpose CPUs!
2) Energy expense of current monetary system. People, computers, ATMs, POS's, paper, time expenditure, inflation/hyperinflation, uncertainty, economic/debt crises, counterfeiting, unemployment - all problems that could be reduced or eliminated by Bitcoin.
3) Future technology. Before cars were invented, one of the biggest concerns was: "How are we going to get rid of the horse manure that's piling up in the world's densest cities?"
Infrared radiation isn't the only way to release heat to space. And even if it were, no one could say that it's not possible for humans+technology to amplify/improve this process.
patio11: that is not how the Bitcoin protocol works.
Even if 99% of the Bitcoin miners agree, they cannot create extra bitcoin; it is simply impossible because that is not something that miners control. Every full node (client) on the Bitcoin network verifies the validity of each block. A block that created more bitcoins than allowed by the protocol would be rejected by the clients (and the miners who follow the original rules). The "extra" bitcoins would be on a hard fork and thus invalid to anyone on the main (original) blockchain.
