The principle underlying the creation of cryptocurrencies like Bitcoin is decentralisation combined with trustless peer-to-peer exchange. Traditional financial systems rely on central authorities such as banks or governments to validate and process transactions. Bitcoin was designed to remove this reliance by introducing a system where participants can transact directly without intermediaries. This is made possible through blockchain technology, which acts as a transparent, immutable ledger shared across a distributed network of computers.

At the core of this principle is consensus. Instead of a single authority controlling records, the network uses mechanisms like proof-of-work to ensure that all participants agree on the validity of transactions. Each block added to the chain must be verified through cryptographic algorithms, making fraud or double-spending nearly impossible without enormous computing power. This ensures trust is placed not in institutions, but in mathematics and code.

Another critical element is scarcity. Bitcoin’s supply is capped at 21 million coins, following the principle of controlled issuance. This design mirrors precious metals like gold, creating digital scarcity that supports long-term value. Transparency, security, and immutability further reinforce the principle by ensuring every participant can verify transactions independently.

Together, these principles create a decentralised financial system where trust is distributed, security is ensured by cryptography, and value emerges from scarcity and network consensus.
