Blockchain & Cryptocurrency Integration Flashcards

What is blockchain technology?

Answer: A decentralized ledger for tracking transactions

Blockchain technology is fundamentally a decentralized, distributed ledger system. It records transactions across a network of computers, ensuring that data is transparent, immutable, and resistant to tampering without relying on a central authority. This makes it a secure and efficient way to track and verify information.

How does blockchain ensure security in Fintech?

Answer: By using cryptography to secure transaction data

Blockchain ensures security in Fintech primarily through the use of advanced cryptography. Each block of transactions is cryptographically linked to the previous one, forming an immutable chain. This cryptographic hashing makes it extremely difficult to alter past transactions without invalidating subsequent blocks, thereby maintaining data integrity and preventing fraud.

What is the role of cryptocurrency in blockchain?

Answer: Cryptocurrency is a digital currency powered by blockchain

Cryptocurrency is a digital or virtual currency that relies on cryptography for security and operates on a blockchain. The blockchain serves as the underlying technology, providing the decentralized and immutable public ledger where all cryptocurrency transactions are verified and recorded. Therefore, cryptocurrency is an application or product powered by blockchain.

Why is decentralization important in blockchain for Fintech?

Answer: It prevents unauthorized access and centralization of power

Decentralization is crucial in blockchain for Fintech because it distributes control and data across a network of participants, eliminating a single point of failure. This prevents any one entity from having absolute power or being a central target for cyberattacks, enhancing security, transparency, and resistance to censorship or manipulation within financial systems.

What is a smart contract in blockchain?

Answer: A contract that is executed automatically when conditions are met

A smart contract is a self-executing contract with the terms of the agreement directly written into lines of code on a blockchain. These contracts automatically execute, verify, or enforce the agreement when predefined conditions are met, without the need for intermediaries. This automates processes, reduces the need for trust between parties, and enhances efficiency.

What is cryptocurrency mining?

Answer: The process of solving cryptographic problems to secure blockchain

Cryptocurrency mining is the process by which new transactions are verified and added to the blockchain. Miners use powerful computers to solve complex cryptographic puzzles, and upon successful completion, they are rewarded with new cryptocurrency and the right to add a new block of transactions to the chain. This process secures the network, validates transactions, and creates new units of cryptocurrency.

How do blockchain and cryptocurrency impact Fintech security?

Answer: By using encryption, decentralization, and transparent records

Blockchain and cryptocurrency significantly impact Fintech security by leveraging encryption, decentralization, and transparent records. Encryption secures individual transaction data, decentralization distributes the ledger to prevent single points of failure, and transparent, immutable records ensure all participants can verify transactions, making fraud extremely difficult to conceal and enhancing overall trust.

What are the benefits of blockchain for Fintech companies?

Answer: It improves transparency and reduces transaction costs

Blockchain offers significant benefits to Fintech companies by improving transparency, as all validated transactions are recorded on a public, immutable ledger accessible to network participants. It also reduces transaction costs by eliminating the need for intermediaries and streamlining processes, leading to more efficient, secure, and cost-effective financial services.

How is cryptocurrency used for cross-border payments in Fintech?

Answer: By enabling direct, low-cost payments between users

Cryptocurrency is used for cross-border payments in Fintech by enabling direct peer-to-peer transactions without the need for traditional banking intermediaries. This bypasses costly and time-consuming currency conversions and international transfer fees, making cross-border payments faster, cheaper, and more accessible globally for individuals and businesses.
