How does Bitcoin work?

Table of Contents


It is not easy to read and can make bookkeeping a little annoying, but it allows Bitcoin transactions to be tracked across the network, which is important given the Bitcoin mantra of transparency and immutability. By using this system, people can trace every Bitcoin transaction back to the origin of the currency, with the understanding that anyone can send a Bitcoin to anyone at any time. By routing transactions through banks and other financial service providers, each transaction is validated by each node in the Bitcoin network and recorded on a secure blockchain.    

Once approved, the transaction will be merged with other transactions to form a block that will be added to the ever-growing transaction chain. The transaction data is then sent via a decentralized network of Bitcoin nodes.  

Once completed the block is encrypted and the transaction log is permanent; it cannot be removed from the blockchain or altered. The blockchain is public, which means that anyone who owns the blockchain can view the transaction logs.

Public blockchains allow users (who need computing power) to participate in the authorization and recording of transactions on the blockchain via nodes. Each node has its own copy of the Bitcoin blockchain, and when the network approves or dismantles a block, it is updated, trusted, and verified. Network nodes validate transactions and add them to their copies of the blockchain, which are then broadcast and added to other nodes.    

Bitcoin transactions make the existing public register accessible to everyone, making transactions harder to reverse and harder to forge. There is no central authority to oversee Bitcoin transactions, but participants themselves create and verify transaction data blocks. Bitcoin banks and apps on the network confirm transactions.    

The truth is that there is no such thing as a Bitcoin wallet, which is merely an agreement between the network to hold coins. Wallets can be described as a place where up to 122 Bitcoin transactions can be accommodated, but by nature Bitcoin is inextricably linked to the blockchain, the transaction book.    

The transaction will be transferred to the rest of the Bitcoin network nodes which will check if Alicea is able to access the input and verify that it matches the public key it claims to have. Once the transaction has been sent to all nodes, they forward it to the network until it reaches the mine nodes.

Behind the network of Bitcoin users who trade the cryptocurrency themselves is a network of miners who record transactions on the blockchain. Every ten minutes, transactions are collected by miners in groups called blocks and added to the Bitcoin blockchain. Once a transaction is broadcast on the Bitcoin network, miners bundle a large collection of transactions into a block that completes cryptographic calculations that are difficult to generate but easy to verify.    

The way miners receive their bitcoin is when a mining team adds a transaction to a block on their node and announces that they have received a predetermined bitcoin for mining the block. The first miner to release the next block sends it to the Bitcoin network and, if it proves correct, it is added to the blockchain. When a new block hex is verified and added to a copy of the blockchain by the network, the miner is paid in Bitcoin.    

Once they have confirmed a transaction and added it to the blockchain, they receive a reward of new Bitcoins. Miners have special computer equipment capable of performing the advanced mathematical calculations and cryptography needed to validate bitcoin transactions. Not only are they working to verify transactions and add blocks to the distributed register, but they also want the Bitcoin network to work smoothly so that they can be compensated for their work.


Bitcoin miners operate complex computer platforms that solve complex puzzles in an effort to confirm a group of transactions known as blocks. If successful these blocks will be added to the Bitcoin record and miners will be awarded with a small number of bitcoins. Miners compete to be the first to validate new blocks and the victorious miners receive newly created bitcoins for their efforts. When a valid block is added to a copy of Bitcoin around the world, the miners begin work on the next block.    

Bitcoin mining adds new transactions to the Bitcoin blockchain. People choose Bitcoin through a process called proof-of-work, which involves computers solving mathematical puzzles to verify transactions. Bitcoin code rewards miners with new Bitcoins to continue working on solving puzzles and supporting the system overall.    

Rather than relying on a government or financial institution to create or manage it, Bitcoin relies on a vast decentralized computer network of individuals and groups known as miners to validate and track transactions using cryptography and advanced mathematics. Key takeaways Bitcoin is a digital currency and decentralized system that records transactions on a distributed ledger called a blockchain.

When bitcoin is created and transactions take place, it consists in part of a collection of data known as blocks. When a block is filled, it inserts into the blockchain in sequential order and is validated by miners in the Bitcoin network.   

To be added to the Bitcoin blockchain, a transaction in a block must be verified by a majority of Bitcoin holders, and a unique code is used to identify the user’s wallet so the transaction matches the correct encryption pattern. Due to the statistical randomness of the blockchain, no verification code is required for each transaction, reducing the risk of fraudulent Bitcoin transactions.
