Confirmed bitcoin transactions are irreversible because they’re secured by cryptographic proofs and recorded on a decentralized blockchain, making alteration economically and technically unfeasible.
A 51% attack occurs when a single entity controls most mining power, enabling them to manipulate transactions, double-spend coins, and undermine trust in a blockchain network.
bitcoin mining consumes vast energy because miners race to solve complex cryptographic puzzles. This proof-of-work process secures the network but requires massive computing power.
bitcoin is no longer just a speculative asset; it’s slowly entering daily life. From online retailers to select cafes, acceptance is growing, but remains uneven by region and industry.
SegWit, or Segregated Witness, reshapes bitcoin transactions by separating signatures from main data. This upgrade improves scalability, lowers fees, and mitigates transaction malleability.
Can bitcoin truly replace traditional money? This question raises key issues about stability, regulation, scalability, and trust in digital systems versus long‑established currencies.
bitcoin halving is a programmed event that cuts mining rewards in half, limiting supply growth. It helps control inflation, impacts miner profitability, and can influence market dynamics.
A bitcoin hard fork occurs when the network’s rules change in a way that is not backward-compatible, splitting the blockchain into two separate chains and creating distinct assets.
