Hacks and Security

There have been several instances where centralized Bitcoin exchanges and wallets have been hacked, resulting in the loss of Bitcoins for the affected users. It is important for users to take steps to protect their Bitcoin and keep their wallets secure and not trust centralized exchanges.
However, it is important to note that the Bitcoin network itself has never been hacked. The decentralized nature of the Bitcoin network, which is secured by cryptographic techniques, makes it extremely difficult to hack.
It is important for users to be aware of the potential risks and to take steps to secure their Bitcoin, such as using strong passwords and keeping their software up to date. It is also important to use reputable and secure wallets and to be cautious when interacting with centralized exchanges.

Features

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 [SHA256] (Secure Hash Algorithm 256).
  • The lowest denomination of bitcoin for now is 1 Satoshi. There are 100 million Satoshi’s to every bitcoin. That is 8 numbers behind the coma, (1 Satoshi = 0,00000001 Bitcoin).
  • 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:
Hash Equals = Nonce guesses
1 Hash 1
1024 Hashes 1 KiloHash 1024
1024 KiloHashes 1 MegaHash 1 048 576
1024 MegaHashes 1 GigaHash 1 073 741 824
1024 GigaHashes 1 TeraHash 1 099 511 627 776
1024 TeraHashes 1 PetaHash 1 125 899 906 842 620
1024 PetaHashes 1 ExaHash 1 152 921 504 606 850 000
  • As of 30th of January 2023 the blockchain is running at approximately 281,42 ExaHashes per second.
  • 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. 0.22.0 the block size limit is set to 1 Mbit of transaction data.
    • Many new software proposals with larger block sizes have been set on the network backward compatible with Bitcoin Core.
    • To change the current software (Hard fork) 75% of miners need to be mining onto the new software. When 75% is reached, there will be a "Grace period" of 1,209,600 seconds (two weeks) before the new features will be in effect and the Hard fork is completed. This according to BIP0101.
