What is Bitcoin:

“Bitcoin is a non-debt based, irreversible, digital asset, with an intrinsic value in the security and inclusion of the payment system and decentralized governance structure that runs on a global transparent ledger on open networks like the Internet.”

  • Non-Debt Based, There is no lone connected, like a piece of Gold. The opposite would be value of paper money, not coins, is a lone paper form the central bank and digital money is a what the bank own or has lent you.
  • Irreversible, Once a transaction is done there is no going back. No one can delete a transaction, just create a new transaction to send the value back.
  • Digital asset, The thing (asset) is bits and bytes on a computer (digital) not physical.
  • Intrinsic, The Origin is a medical term, not a financial. It means you need something to get a function ex. you need a knee to bend your leg. In this case you need security, inclusion and agreed decentralized governance structure to get value.
  • Security, The strength of the system.
  • Inclusion, How many can take part in this system
  • Decentralized, no singe point of failure can stop or hurt the system in anyway.
  • Governance structure, Who is in charge, if anyone and what are the rules (law).
  • Transparent, anyone can see or look up all the information that is available for system.
  • Ledger, a record of all inputs / transactions.


The features of Bitcoin are: The features organizations want:
Open Source Closed Source
Global Local
Immutable permanent ledger Editable ledger (for correcting slipups)
Permission-less (anyone can join) Permission (Only for verified customers)
Censorship resistant Censored (think about sending value to WikiLeaks)
Decentralized / Flat structure Centralized / Hierarchical structure
Pseudonymous Control Identity / KYC
Proof of work consensus Proof of Stake / PoAuthority / PoState
Innovate without permission Controlled team of innovators
This is Bitcoin. This is not Bitcoin
The Internet of money or IoM like IoT (Internet of things), a currency / value token that can buy gods and services globally using the Internet.
The value token network that runs on the Internet with sets or blocks of transaction data packaged and blocks are built on top of each other to locked them in sequential order.
Digital assets / money that is programmable and can be self regulated.

Bitcoin FAQ

  • Only 20 999 999,99755530 or less bitcoins will ever exist.
  • The consensus algorithm is Proof of Work.
  • The lowest denomination of bitcoin is 1 Satoshi. There are 100 million Satoshi’s to every bitcoin. That is 8 numbers behind the coma, (1 Satoshi = 0,00000001 Bitcoin).
  • Every Satoshi can be programed to carry 256 characters.
  • Bitcoin is run decentralized on a flat structure as opposed to a centralized hierarchical structure.
  • Bitcoin is design to be the senders “push transaction” and that no entity like banks, governments or 3rd party can stop a sender from pushing transaction to be executed. In effect the sender is the ultimate authority and decides who he or she pays value to.
  • The Bitcoin code has never been successfully hacked, but we have seen many examples of centralized wallets that have been broken into (Hacked).
  • The software is open sours and the code is available on GitHub.
  • The difficulty parameter, that is built into the software, is adjusted every 2016 blocks to change to try and keep a 10-minute block time on average based on the blockchain performance the last 2016 blocks.
  • Hashing is a brute-forced mechanism by the miners (supercomputers with ASIC CPU’s (Application Specific Integrated Circuits Central Processing Units)) guessing the right combination.
  • An executed SHA256 hash is one try to guess the right combination on the complex lock holding the blocks together.
    • Side note:
      • 1 guess = 1 hash
      • 1024 hash = 1 Kilohash
      • 1024 kilohash = 1 Megahash
      • 1024 Megahash = 1 Gigahash
      • 1024 Gigahash = 1 Terahash
      • 1024 Terahash = 1 Petahash
      • 1024 Petahash = 1 Exahash
  • The miners get rewarded for the blocks that they solve and broadcast to the rest of the network first.
  • Every 210.000 blocks the miner reward gets halved.
  • In the current bitcoin software, Bitcoin Core ver. 0.17.1 the block size limit is set to 1 Mbite of transaction data.
    • Many new proposals of software with larger block size have been set on the network backwards compatible with Bitcoin Core.
    • To change the current software (Hard fork) 75% of miners need to be mining on to the new software. At the time when 75% is reached, there will be "Grace period" of 1,209,600 second (two weeks) before the new features will be in effect and the Hard fork is completed. This acording to BIP0101.
