Transaction record A data structure that represents transactions on a blockchain. Block A data structure that contains a set of verified transactions and is added to the blockchain. Fork event A situation in which multiple competing versions of a blockchain are created. Miner A node that verifies and adds transactions to the blockchain. Proof of Work A mechanism that requires miners to expend computing power to solve complex problems in order to add new blocks. Oracle A third-party service that provides smart contracts with data from the outside world. Quiz

Answer

Blockchain technology provides a decentralized, transparent, and tamper-proof record of transactions. This makes business transactions more efficient, secure, and cost-effective.

Smart contracts are self-executing contracts stored on the blockchain that are automatically executed when predefined conditions are met. They can automate the execution of contracts and reduce the need for intermediaries.

Traditional fiat currency transactions rely on centralized intermediaries such as banks or payment processors to process and verify transactions. Cryptocurrency transactions are decentralized and verified by the blockchain network.

Nested smart contracts can contain dispute resolution clauses, such as return policies or arbitration mechanisms. When these nested contracts are triggered, they can automatically execute predefined dispute resolution processes.

The payment service system acts as an intermediary between merchants and blockchain networks. It helps merchants create blockchain-enforced contracts, manage cryptocurrency transactions, and provide dispute resolution services.

Merchants can customize the terms of the contract by specifying payment terms, return policies, dispute resolution mechanisms, and delivery schedules. The payment service system provides a user-friendly interface to simplify this process.

Blockchain-enforced contracts can include nested smart contracts that allow for refunds or returns when certain conditions are met. This provides recourse to customers and protects them from fraud or non-performance of contracts.

Payment service systems can use multi-signature wallets or escrow services to manage cryptocurrency transactions without direct access to users' private keys. This ensures the safety of funds and allows for dispute resolution when needed.

Oracles provide smart contracts with data from the outside world, such as market prices, weather conditions, or delivery confirmations. This enables blockchain-enforced contracts to be executed based on real-world events.

Forking events occur when multiple miners in a blockchain network create new blocks at the same time, resulting in multiple versions of the blockchain. Typically, the network resolves forks by selecting the longest chain that contains the most proof of work.
