In October 2008, Satoshi Nakamoto — a pseudonym used by the developer or developer of Bitcoin — launched an alternative electronic cash system that allows direct money transfers from one party to another without going through a financial institution. We have published a white paper detailing our method.
The paper, titled “Bitcoin: A Peer-to-Peer Electronic Cash System,” explores how key aspects of Bitcoin (BTC) can support trustless electronic cash systems using cryptographic proofs. provided an oversight.
This paper defines an electronic coin as a set of digital signatures. It also outlines how the previous owner’s public and private keys are used to perform a transfer of ownership, combined with the next owner’s public key to create a digital signature on the transaction block.
Each block is linked to the previous block using a hash, and the entire chain of blocks constitutes the entire distributed ledger built on in the process.
This is how the term blockchain came about. To add transactions to blocks, the timestamp server continuously broadcasts hashes to a network of nodes or computers in the network.
Employing the SHA-256 hashing algorithm, each block can only produce one hash, and the BTC network uses this process to set the difficulty level so that a new block is mined every 10 minutes. .
Known as a Proof of Work (PoW) system, this system makes it impossible for any node to modify transactions in the blockchain, thereby making it secure.
How the BTC Blockchain Network Processes Transactions
All new transactions are broadcast to the nodes. Each node tries to find a hard proof of work to fit new transactions into blocks.
When a node finds proof of work, it broadcasts the block to all nodes and only accepts the block if all recorded transactions are valid.
This is represented by a node that uses the hash of the accepted block to create the next block in the chain.
Nodes consider the longest chain to be the correct one, so if two versions of the blockchain are submitted, the node will work with both until one is longer and the accepted version.
A new transaction broadcast must reach all nodes as it will eventually be processed into blocks and made available to all nodes.
This allows nodes to switch off and on whenever they want to contribute to the network and add blocks to the Bitcoin blockchain, contributing as much computing power as they need.
Incentivize computing power delivered in newly minted BTC
Nakamoto envisioned an incentive system for nodes to support the BTC network by distributing BTC in return for providing computing power so that the entire network would be free from double spending and malicious attacks. did.
Therefore, the first transaction within a block starts a new BTC owned by the creator of the block, and nodes continue to support the network to mine new BTC.
As the number of BTC in circulation increases, the computational power required to mine new Bitcoins increases significantly, with a focus on the transaction fee aspect acting as a more regular incentive.
Once a given number of BTC have been circulated, transaction fees may form a large part of the incentives available to nodes, and are considered completely inflation-free as an additional measure.
As a result, potential attackers can deploy additional computing power to mint more new coins and make more transactions than trying to steal funds by modifying the blockchain with a new version. You will find it more profitable to earn commission-based incentives.
Securely manage multiple transactions with new privacy model
Nakamoto’s whitepaper also describes how hashing transactions with a Merkle tree can save disk space and facilitate payment verification without running an entire network node.
However, what set the BTC network apart from traditional banking channels was the privacy it offered, even though all transactions were broadcast on a public blockchain.
This is done by keeping the public key anonymous and requiring a new key pair to be used for each transaction.
Transactions are public, and trust is maintained by a network of nodes that validate every block of a transaction, while changing the key pair used allows users’ identities to remain behind an impenetrable firewall.
Using the framework of a digital coin created from digital signatures and combined with elements of cryptography, the BTC Whitepaper proposed a peer-to-peer trading network that introduces revolutionary new trading methods. Safe, borderless and accessible to everyone.
