The technology behind bitcoin – how it works

Bitcoin’s blockchain is a transformative technology that allows users to securely send and receive funds and keep track of all their transactions. 


Although many people know about bitcoin and how it has inspired an entire global cryptocurrency industry, there is very little knowledge about its technology. And, that is a little below the point because bitcoin’s underlying technology is the powerhouse that enables it to operate as a decentralized digital currency. The following article discusses the technology and how it works. 

Bitcoin’s Underlying Technology 

Blockchain is the technology behind bitcoin, which other cryptocurrencies rely on too. Some describe it as the crown jewel with the potential to change almost every aspect of human life, far beyond the crypto world. So, what exactly is blockchain?

Blockchain is like a database but in digital format. It has a unique way of securely recording and broadcasting vast amounts of data over a specified network. It is a distributed ledger that validates and stores records across multiple computers, referred to as nodes.

However, nodes have greater computational power than basic home computers. For more information and details about how the app works, you can visit this website available here.

The nodes are operated by anonymous people, spread across different geographical regions. They verify, approve and compile the information within the ledger. That is different from conventional record-keeping methods that store data in a central place, such as servers. 

Blockchain compiles the data added to the ledger into blocks. Each block holds a given amount of data, so new blocks are continuously added to the existing catalog, creating a chain of information. Every block also has a unique identifier, known as a cryptographic hash, which is code-protected. That helps to identify the blocks and protects the data from infringement by anyone without the designated code. 

The cryptographic hash is a set of letters and numbers up to 64 digits long. Once information is entered into the blockchain and encrypted using the cryptographic hash, it becomes permanent and irreversible. Each node on the network contains a record of all the information added to the blockchain since its inception.

That means altering the data on any of the nodes will create inconsistencies with the information on the other computers. The node cross-checks with the others to correct the information or discards it, depending on most computers’ records on the network, if this happens. 

How Blockchain Works in Bitcoin 

Blockchain technology mainly verifies and records bitcoin transactions, creating a digital public ledger accessible to all bitcoin users. For example, when you buy bitcoin to invest on a platform, the transaction data will be sent to the decentralized nodes on the bitcoin network for validation. 

After the transaction is approved, it is compiled with others to create a block and added to the existing chain of data. The completed block is encrypted, and the information therein becomes permanent. 

Bitcoin’s underlying blockchain is public, which means all bitcoin uses can access the transaction records. The data shows all the accounts conducting transactions on the bitcoin network. However, bitcoin users can also transact anonymously without revealing their identities. 

Since bitcoin’s blockchain is public, users with the skills and computational power to operate as nodes may also join the action. That process is proof-of-work, which requires powerful and specialized computers to solve complex math puzzles. 

Blockchain technology offers a secure, transparent, and faster solution by recording bitcoin transactions. The digitized process eliminates the need for third parties to verify bitcoin transactions, ensuring quick and low-cost money transfers. Bitcoin transactions usually take just a few minutes to process and cost much less than electronic money transfers. 

As many innovators have said, bitcoin’s blockchain is a transformative technology that allows users to securely send and receive funds and keep track of all their transactions.
