Questions & Answers

Q: What is bitcoin and how does it work?

Bitcoin is a big spreadsheet or ledger that keeps track of who has sent what to whom. It is a purely digital asset with no corresponding physical asset. The ledger is secured through distributed technology, where copies of the ledger are kept all over the world and a majority of them have to agree on the correct ledger.

Q: Why is the security of the ledger important?

If the ledger that keeps track of valuable assets is not secure, it can be easily hacked or altered. By using distributed technology where multiple copies of the ledger exist, the security of the ledger is enhanced. Even if some copies of the ledger are hacked or altered, the full public record remains intact.

Q: How is bitcoin different from traditional payment systems like PayPal?

Bitcoin is an open-source software protocol that allows individuals to make their own entries on the ledger in a decentralized manner. In contrast, traditional payment systems like PayPal are centralized and require a company to keep track of the ledger. Bitcoin allows individuals to have direct control over their digital assets and removes the need for intermediaries.

Q: How can bitcoin be used for international money transfers?

Bitcoin enables the instantaneous movement of assets internationally without the need for traditional banking systems. For example, to send money to Japan, one can initiate a dollar transfer through a linked account to a Bitcoin service provider. The dollars can then be exchanged for bitcoins, and the bitcoins can be sent to a recipient's bitcoin address in Japan. The recipient can then convert the bitcoins into their local currency.

Q: What are the advantages of using bitcoin for remittances?

Remittances, which are international money transfers from migrant workers to their families in their home countries, can be expensive and time-consuming. By using bitcoin, remittances can be made instantly and at a lower cost compared to traditional methods. This can greatly benefit vulnerable populations who rely on remittances for their livelihood.

Q: How can bitcoin be used for programmable money?

Bitcoin and other digital currencies allow for the creation of programmable money, where financial transactions can be executed automatically through computer programs. This opens up possibilities for creating complex financial products and contracts without the need for middlemen. For example, smart contracts can be written to distribute money based on specific conditions being met.

Q: How does the use of bitcoin affect traditional financial institutions?

The use of bitcoin and digital currencies may lead to the disintermediation of traditional financial institutions. Individuals may choose to hold their money in bitcoin rather than traditional bank accounts, reducing the need for banks. Additionally, the ability to execute financial transactions directly through computer programs may change the role of banks and other financial intermediaries.

Q: How does the use of bitcoin impact industries like remittances and multinational firms?

Bitcoin can disrupt industries like remittances by enabling direct person-to-person transfers without the need for intermediaries. This can lower transaction costs and make remittances more accessible to vulnerable populations. For multinational firms, using bitcoin can reduce fees associated with moving money internationally and allow for more efficient and secure financial transactions.

Q: What are some potential applications of bitcoin and digital currencies?

Bitcoin and digital currencies have a wide range of potential applications. These include back-end money movements, such as remittances and multinational firm transactions, as well as new services like public recording of messages, low-friction escrow services, and programmable money. The use of digital currencies can enable new markets to grow and make existing ones more efficient.

Q: How does the speaker view the future of bitcoin and digital currencies?

The speaker is optimistic about the potential of bitcoin and digital currencies to revolutionize the way we think about and use money. Just as the internet enabled the movement of information in new ways, digital currencies enable the movement of money in new ways. The speaker believes that with time, entrepreneurs will figure out innovative ways to use this technology and create new services and applications.
