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
The Bitcoin mempool is where valid unconfirmed transactions wait before miners include them in blocks. Fee rates and network demand affect how quickly transactions confirm.
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.
