Quiz Answers

A blockchain is a tamper-proof database of transaction records that is stored, maintained, and updated in a distributed manner. In cryptocurrency, the blockchain records all transactions, ensuring transparency and security without the need for a central authority.

Private blockchains are permissioned, have restrictions on participants, and are usually controlled by a single entity. Public blockchains are decentralized, and anyone can join and participate in the network, such as Bitcoin and Ethereum.

Full nodes store a complete copy of the blockchain, verify transactions, and maintain the integrity of the network. Lightweight nodes rely on full nodes to obtain blockchain data, have fewer resources, and do not participate in the verification process.

Proof of Work is a consensus mechanism that requires nodes (miners) to solve complex mathematical problems to verify transactions and add them to the blockchain. The first node to solve the problem is rewarded, which encourages nodes to maintain the network.

Forks refer to the emergence of different versions of transaction history in a blockchain network. This can happen due to the simultaneous solution of proof of work puzzles, software updates, or changes to the blockchain rules.

Smart contracts are self-executing contracts that are stored on the blockchain and automatically execute when predefined conditions are met. For example, smart contracts can be used to automate supply chain management, payments, or escrow agreements.

A token is an entry on the blockchain that represents ownership or access rights to an asset. It can represent a cryptocurrency, a digital asset, a physical asset (such as real estate), or other tangible or intangible assets.

Non-fungible tokens based on programmable syntax use mathematical operators to define relationships and permissions, allowing flexibility and interoperability. In contrast, tag-based token standards rely on predefined tags and APIs, limiting functionality and extensibility.

The permit field defines the permissions and access controls associated with non-fungible tokens. It specifies which entities can access the data and instructions contained in the token, thereby enhancing security.

Non-fungible tokens based on programmable syntax can establish hierarchical token networks through mathematical operators and hierarchical relationships. This allows the creation of complex ownership structures and access controls, such as in supply chain management or digital identity systems.

Glossary

Term Definitions Blockchain A decentralized and distributed ledger that stores transaction records in a distributed and tamper-proof manner. Cryptocurrency A digital or virtual currency that uses cryptography to secure transactions and control the creation of new units. Smart Contracts Self-executing contracts that are stored on the blockchain and automatically execute when predefined conditions are met. Non-fungible tokens (NFTs) A digital asset that represents ownership of a unique asset (digital or physical). Programmable syntax A syntax that allows mathematical operators to be used to define relationships and logic, providing greater flexibility for non-fungible tokens based on programmable syntax. Forks Different versions of transaction history appear in a blockchain network, which can be caused by a variety of factors. Consensus mechanism The algorithm used in a blockchain network to reach agreement on the validity of transactions and the state of the blockchain. Proof of Work (PoW) A consensus mechanism that requires nodes to solve complex mathematical problems to verify transactions and create new blocks. Proof of Stake (PoS) A consensus mechanism in which nodes are selected to verify transactions based on their stake in the system (the number of tokens held). Token standards provide a set of rules and guidelines for creating and managing tokens, such as ERC-20, ERC-721. API (Application Programming Interface) A set of definitions and protocols that allow different software systems to communicate and interact with each other.
