Questions & Answers

Q: How does Bitcoin differ from traditional currencies?

Unlike traditional currencies, Bitcoin is not backed by a government or bank. It operates on a decentralized network of computers and has a limited supply.

Q: How are Bitcoin transactions verified and secured?

Bitcoin transactions are verified by mining computers, which compete to add transactions to a chain of blocks. The chain ensures the authenticity and prevents double-spending of Bitcoins.

Q: How does mining work in the Bitcoin system?

Mining involves solving complex mathematical problems by guessing numbers. The first miner to solve a problem gets to add a block of transactions to the chain and is rewarded with newly created Bitcoins.

Q: What is the cap on the number of Bitcoins?

There is a cap on the number of Bitcoins that will ever be in circulation. This cap is reached by halving the number of new Bitcoins created with each block every four years. It is estimated that the cap will be reached by around 2140.

Summary & Key Takeaways

• Bitcoin is a digital currency that can be used to buy real-world items, not backed by any government or bank.

• It operates on a network of computers, with a set of rules called mining, which process and record transactions.

• Users can use software wallets to keep track of their balances and make transactions using Bitcoin addresses.
