Unofficial IPv6 Certification

IPv6 Certificate
IPv6 Certification from Hurricane Electric
Hi guys, I have just passed the last IPv6 test of the whole unofficial Hurricane Electric's IPv6 certification process.

This process consists on a lot of questionnaires and IPv6 tests that proves skills and knowledge about IPv6 from the very bottom to the top.

In ascending order of difficulty the tests qualify you from the most basic level called newbie, passing through intermediary levels as enthusiast, administrator, professional, guru and finally the upper level called sage.

In order for me to get the IPv6 Sage level, I had to prove that my own domain vescudero.net is accessible from their IPv6 backbone, that I'm able to send and receive emails through IPv6, get IPv6 DNS glue records, etc.

What does really set Bitcoin apart?

Bitcoin is a pseudonymous, decentralized electronic currency, and it has been designed in such a way that it functions similarly to physical commodity money, such as gold or a fiat currency like the Euro. 

Bitcoin shares most of the properties that 'good money' should have:
  • Divisibility: money should be easily divisible into arbitrary units of value in order to handle all sizes of transactions.
  • Durability: in order to be a reliable store of value, money must stand the test of time.
  • Fungibility (interchangeability): each unit is identical to every other unit. One kilogram of gold is equivalent to another one.
  • Scarcity: it holds its value and does not steal value through arbitrary inflation or deflation.

These are all interesting properties that we usually take for granted, but they are not the only ones. In fact there are some other 'features' that really set bitcoin apart:
  • No chargebacks: irreversible transactions after an hour.
  • Low transaction fees: most transaction fees are free of charge, or nearly so and they will be kept low forever.
  • Pseudonimity: bitcoin restores privacy to electronic payments.
  • Openness: The bitcoin project itself is open souce. The protocol and the code is open to public scrutiny and analysis.
  • Decentralization: bitcoin puts us in control of our own money, no need to trust in financial institutions or issuing authorities.
Nobody knows if bitcoin will be able to survive in the long term, but right now its appealing characteristics makes it a perfect choice for international trading.
