Endnotes

  1. Nakamoto is anonymous so there is no way to confirm his gender. Satoshi could be a man, woman, group of people, company, organization, or government agency. ‘He’ presented himself as male.
  2. “Bitcoin: A Peer-to-Peer Electronic Cash System” Satoshi Nakamoto (2008). Link: https://bitcoin.org/bit coin.pdf
  3. The protocol is ‘Bitcoin’ while the currency is ‘bitcoin’.
  4. Miners perform proof-of-work (POW) exercises on the ‘candidate block’ of unconfirmed transactions. Miners use the computational power of their hardware to rapidly hash the candidate block and generate a
    hash below a defined number known as the difficulty target. The first miner to achieve this is rewarded with 25 BTC at the time of writing.
  5. Two excellent guides to Bitcoin are “Mastering Bitcoin: Unlocking Digital Cryptocurrencies” Andreas Antonopoulos (2014) and “Bitcoin for the Befuddled” Conrad Barski and Chris Wilmer (2014).
  6. “Silk Road: The Untold Story” Wired 23 May 2015. Link: http://www.wired.com/2015/05/silk-road-unt old-story/
  7. The bitcoin price rose from 13 USD on 1 January 2013 to 1,120 USD on 29 November 2013.
  8. “Bitcoin Isn’t the Future of Money – It’s Either a Ponzi Scheme or a Pyramid Scheme” Washington Post 8 June 2015. Link: https://www.washingtonpost.com/news/wonkblog/wp/2015/06/08/bitcoin-isnt-the- future-of-money-its-either-a-ponzi-scheme-or-a-pyramid-scheme/
  9. Bitcoin 2.0 businesses employ the blockchain to – among other uses – issue smart contracts, validate identities, and notarize documents.
  10. That said, Mike Caldwell, founder of Casascius coins, appears in the documentary “The Rise and Rise of
    Bitcoin” (2014) for three minutes and 19 seconds from 45:57. Link: http://www.imdb.com/title/ tt2821314/ He discusses his filming experience at https://casascius.wordpress.com/2013/05/19/casascius- coin-production-featured-in-the-rise-and-rise-of-bitcoin/
  11. This is not to suggest that physical Bitcoin enthusiasts do not research coins. I merely note that, until now, there has not been a comprehensive catalogue which provides data and photographs on all known manufacturers and their products.
  12. The prefix is typically the first eight digits of a coin’s public address. The first character is ‘1’ and each of the next seven characters can be one of 58 examples. As such, there are a total of 2,207,984,167,552
    possibilities which means that the likelihood of finding two public addresses with the same eight first characters is remote. The full public address can either be discovered by entering the first characters on a blockchain website like https://btc.blockr.io/ or is shown on an enclosed certificate.
  13. Casascius holograms were successfully compromised at the DEF CON hacker convention in August
    2013. Caldwell immediately took measures to ensure that future coins were tamper-proof. “Casa- scius Physical Bitcoins Cracked at Defcon” Link: http://codinginmysleep.com/casascius-physical-bi
    coins-cracked-at-defcon/ “Defcon 21: Successful Compromise of the Hologram Reported” Link: https:// casascius.wordpress.com/2013/08/04/defcon-21-successful-compromise-of-the-hologram-reported/
  14. This is only the case for Alitin. Link: http://www.alitinmint.com/Home/About

  25. Nakamoto stated (p. 1) that “[w]hat is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.”
  26. Bitcoin Improvement Proposals (BIPs) are modifications to the Bitcoin protocol or information about suggested amendments. Link: https://en.bitcoin.it/wiki/Bitcoin_Improvement_Proposals
  27. “Casascius” Link: https://casascius.com/2factor/
  28. Some physical Bitcoin producers create their own two factor schemes. While this does secure bitcoin from interlopers, it in no way negates the need for buyers to trust the manufacturers.
  29. Wallet software uses entropy to generate the private key and public key. The resulting public key is hashed with SHA-256 and RIPEMD-160, the hexadecimal prefix 0x01 and checksum is added, and the result is encoded with Base58Check to produce the public address.

The Coin Grading Service UK does grade physical Bitcoin but, confusingly, has a proprietary grading system. The vast majority of collectors, including those in the UK, use ANACS.
