Glossary:
Blockchain or Block Explorer: An explorer is basically a blockchain search engine. It can be used to search for just about any information pertaining to the state of a specific blockchain that someone might want to know.
A block explorer can be thought of as a search engine for a blockchain; allowing a user to find lots of different information about that blockchain.
To use a block explorer, you simply visit its website and enter the information you’re looking for. To look up a pending transaction currently stored in the Mempool, for example, you could enter the transaction hash ID provided by your wallet or exchange.
Mempool: The mempool (memory pool) is a smaller database of unconfirmed or pending transactions which every node keeps. When a transaction is confirmed by being included in a block, it is removed from the mempool.
Node: A blockchain node is a device, usually a computer, that participates in a blockchain network. It runs the blockchain protocol's software.
Consensus mechanism: is a fault-tolerant mechanism that is used in computer and blockchain systems to achieve the necessary agreement on a single data value or a single state of the network among distributed processes or multi-agent systems, such as with cryptocurrencies.
Cryptography: Cryptography is a method of securing data from unauthorized access. In the blockchain, cryptography is used to secure transactions taking place between two nodes in a blockchain network.
Wallet: A cryptocurrency wallet is a device, physical medium, program or a service which stores the public and/or private keys for cryptocurrency transactions.
NFT: A non-fungible token (NFT) is a unique digital identifier that cannot be copied, substituted, or subdivided, that is recorded in a blockchain, and that is used to certify ownership and authenticity.
Tokens: Web 3.0 tokens are digital assets that are associated with the vision of creating a decentralized Internet.
Tokens are the digital assets that make up the blockchain ecosystem. Essentially, they are the modern-day equivalent of currency and are used as a medium of exchange within the crypto-economy. There are thousands of different tokens which can be used in various ways.
