Traditional financial systems rely on centralised institutions to process, verify, and settle transactions. Banks act as intermediaries, ensuring compliance and security but also introducing inefficiencies. Transactions can be reversed, delayed, or frozen based on regulatory decisions, fraud concerns, or institutional policies.
Bitcoin removes these layers of control. It operates on a decentralised network, where miners validate transactions through Proof of Work (PoW). Once a transaction is confirmed, it becomes irreversible, forming a final settlement system that operates independently of banks and governments. Mining does more than secure the network—it enforces absolute financial finality, making Bitcoin the most reliable transaction system in history.
The modern banking system is built on trust-based settlement networks. Transactions must pass through multiple intermediaries, each adding layers of verification, compliance checks, and potential restrictions. The centralisation of settlement has deep historical roots.
• According to Rondo Cameron in Banking in the Early Stages of Industrialization, early financial institutions provided capital for industrial growth but operated locally. Trust-based lending dominated financial markets, with settlements handled manually through ledgers and in-person agreements. As banking expanded, institutions centralised control, improving efficiency but creating dependence on intermediaries.
• Fernand Braudel, in Civilization and Capitalism, explores how financial systems developed from simple exchanges to structured banking. The first clearinghouses appeared to standardise transactions, reducing fraud but increasing the complexity of settlements. This reliance on central entities for final approval introduced delays and restrictions that remain in modern banking.
Today, financial settlements remain slow, expensive, and reversible. Cross-border transactions can take days, with funds subject to compliance reviews, intermediary fees, and capital controls. Bitcoin eliminates these inefficiencies, offering direct, final settlement through mining.
Bitcoin’s Proof-of-Work (PoW) mechanism guarantees finality at the protocol level, removing the need for financial intermediaries. Transactions are validated by miners, who solve cryptographic puzzles to add them to the blockchain. This process locks transactions into a chain of blocks, making them increasingly difficult to alter over time.
Unlike traditional settlements, which remain reversible for days or weeks, Bitcoin’s finality is determined by computational security. Once a transaction is recorded, reversing it requires redoing the PoW for that block and every subsequent block, an effort that scales exponentially as new blocks are added.
The Bitcoin Whitepaper explains that each new block builds on the previous one, reinforcing security. More confirmations increase finality:
• 1 confirmation: Included in a block but still vulnerable to reorganisation.
• 6 confirmations: Considered final under normal conditions.
• 800 confirmations (5.5 days): Practically irreversible, even against theoretical attacks.
An attacker attempting to alter a transaction would need to control over 50% of the network’s mining power, a 51% attack. The energy and cost required make such an attack irrational, ensuring Bitcoin remains the most secure financial settlement layer.
Bitcoin’s Proof-of-Work (PoW) system makes altering past transactions nearly impossible. Unlike traditional finance, where settlements can be reversed by banks or governments, Bitcoin transactions are secured by a decentralised network of miners competing to validate new blocks.
For a transaction to be reversed, an attacker would need to gain majority control of the network’s computational power, known as a 51% attack. This means they would have to outperform all honest miners combined, re-mine the altered block, and redo the work for every subsequent block before the network moves further ahead.
• Immense Energy Demand – The Bitcoin network consumes as much energy as some countries. Running enough mining machines to overtake the network would require unrealistic power consumption.
• Mining Hardware Costs – Bitcoin miners invest in specialised, high-performance hardware (ASICs). An attacker would need to acquire a majority of these machines, which are expensive, difficult to obtain, and constantly improving.
• Economic Disincentives – Even if an attack were successful, it would undermine trust in Bitcoin, causing its value to crash. The attacker’s mining investment would become worthless.
• Defensive Mechanisms – The Bitcoin network would detect manipulation, and honest miners and nodes would reject fraudulent transactions.
Bitcoin’s security relies on making attacks economically irrational and technically unfeasible. The cost of overpowering the network far exceeds any potential reward, ensuring transaction finality and long-term trust in Bitcoin’s settlement system.
Bitcoin functions as a global, permissionless settlement network, making it vastly superior to traditional banking systems.

What Makes Bitcoin Superior?
Bitcoin’s mining network acts as a final settlement layer, ensuring transactions are secure, final, and globally accessible without external approval.
Bitcoin: The Ultimate Settlement System
Bitcoin mining guarantees final, irreversible transactions without banks or intermediaries. Traditional finance relies on trust-based settlements, subject to delays, reversals, and third-party control. Bitcoin eliminates these inefficiencies, securing transactions through Proof-of-Work. Once confirmed, a transaction cannot be reversed, altered, or censored.
