Bitcoin was introduced in 2009 and became the first widely adopted decentralized digital currency. Its supply is capped at twenty-one million coins, and the network is secured through a proof-of-work mechanism. Because transfers do not require a bank or clearing house in the middle, cross-border payments can settle in minutes rather than business days, although confirmation times still vary with network load.

A blockchain is fundamentally a distributed ledger. Transactions are grouped into blocks, and each block is cryptographically linked to the one before it, which makes historical records extremely difficult to alter after the fact. Instead of a single administrator holding write access, the ledger is replicated across many independent nodes, and every transfer must be agreed upon by the network's consensus rules before it becomes final.

On-chain transaction fees depend largely on congestion. When many transactions are competing for limited block space, validators prioritize the ones offering higher fees, so the cost of inclusion can rise sharply during busy periods. Batching transfers, using layer-two networks, or simply waiting for quieter hours are common ways to keep costs down.
