bitcoin’s protocol cuts block rewards in half every 210,000 blocks, roughly every four years, slowing new supply, reinforcing scarcity, and influencing miner incentives and market dynamics.
bitcoin’s first halving in November 2012 cut the block reward from 50 to 25 BTC. This programmed event reduced new supply, tested network security, and set a precedent for future halvings.
Despite popular belief, no single entity controls bitcoin. Power is distributed across miners, node operators, developers, and users, whose consensus secures and governs the network.
bitcoin can move without the internet. Using long‑range radio and dedicated satellites, transactions can be broadcast, received, and verified even in remote or censored regions.
Despite numerous exchange breaches and wallet thefts, bitcoin’s core protocol has never been hacked. Its security stems from decentralization, open review, and robust cryptography.
Public keys are cryptographic identifiers that let others send bitcoin to you. They derive from private keys and enable secure, verifiable transactions without revealing your secret key.
Hardware wallets protect private keys offline, while multisig requires multiple approvals to spend funds. Together they significantly reduce single points of failure in bitcoin security.
bitcoin transaction fees have surged amid network congestion, as increased trading and on-chain activity strain limited block space, causing delays and higher costs for users.
More companies are exploring bitcoin as a payment option, attracted by lower fees, global reach, and marketing appeal, while weighing volatility, regulation, and accounting challenges.
