Blockchain is a value transfer verification system. Just like on the internet, where you can send information, you can send value on a Blockchain network. The difference is that on the internet you send a copy of the information, but on Blockchain you send the actual value without retaining a copy. The transaction itself can be verified by anyone connected to the network, so no one can cheat the system. So, no one can say they did not receive the value when they have received it. Equally, no one can say they sent the value if they did not.  
A blockchain is a decentralized, digital ledger that is used to record transactions across a network of computers. Each block in the chain contains a record of multiple transactions, and once a block is added to the chain, the data it contains cannot be altered. This makes it an immutable record of all transactions on the network.<div>
 
The key feature of blockchain technology is that it allows for secure and transparent record-keeping without the need for a central authority.

Who is Mr. Bitcoin Norway?

My name is Bjorn Bjercke and I have over 20 year's experience with IT solutions, where of 12 year's within the Banking and Finance sector. In September 2013 my interest in Bitcoin sparked. My profile page on Linkedin

A simple definition on Bitcoin

Bitcoin is a decentralized digital currency that uses cryptography for security and operates without a central authority such as a government or financial institution. Bitcoin transactions are recorded on a publicly distributed ledger called the blockchain.
Bitcoin has several characteristics that make it unique as a digital asset:
  • Non-debt-based: Bitcoin is not a debt instrument like a traditional currency or a financial asset like a bond. It is an independent asset that has value in itself.
  • Irreversible: Once a bitcoin transaction is made, it cannot be reversed. This is because the blockchain is an immutable record of all transactions, and once a transaction is included in the blockchain, it cannot be changed.
  • Digital: Bitcoin exists purely digitally and can be stored and transferred electronically.
  • Intrinsic value: The value of bitcoin is not derived from any external asset or authority, but rather from the security and inclusiveness of the payment system and decentralized governance structure on which it runs.
  • Transparent ledger: The blockchain is a transparent and open record of all bitcoin transactions, allowing for transparency and accountability in the system.

Overall, bitcoin is a decentralized digital currency that operates on a transparent, open network and has several unique characteristics that make it a valuable asset.

A simple definition on Blockchain

A blockchain is a decentralized, digital ledger that is used to record transactions across a network of computers. Each block in the chain contains a record of multiple transactions, and once a block is added to the chain, the data it contains cannot be altered. This makes it an immutable record of all transactions on the network.
The key feature of blockchain technology is that it allows for secure and transparent record-keeping without the need for a central authority. Because the transactions are recorded and verified by multiple parties, it is difficult for anyone to cheat the system or manipulate the data. This makes it an attractive technology for a wide range of applications, including financial transactions, supply chain management, and voting systems.

Definition of 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.

What we need

Blockchain is not solving a problem; it's eliminating their existence

No government can attack Bitcoin

If your thinking about using bitcoin for illegal activity, think again and see this:
