Bitcoin is the first widely adopted public cryptocurrency network. It is best understood as a payment and settlement system with strict issuance rules, public verification, and proof-of-work mining.
Bitcoin
The Bitcoin halving is a scheduled reduction in the block subsidy paid to miners. It is part of Bitcoin's issuance design, not a guaranteed market signal.
Bitcoin
Bitcoin transaction fees help users compete for limited block space. Fee choices can affect confirmation speed, cost, and user experience.
Bitcoin Transactions
The Lightning Network is a payment-channel system built around Bitcoin that aims to make smaller, faster payments more practical.
Bitcoin Scaling
Bitcoin does not track balances like a bank account. It tracks unspent transaction outputs, or UTXOs, that wallets select and spend in later transactions.
Bitcoin Fundamentals

Bitcoin Transactions
A Bitcoin private key is secret data that can authorize spending. Anyone who controls the relevant private key can move the associated bitcoin under network rules.
