Blockchain technology is built upon the concept of a distributed ledger, where data is stored across multiple nodes in a network, ensuring transparency and security.

Hashing functions are employed in blockchain to create unique and irreversible representations of data, ensuring the integrity and authenticity of transactions.

Blockchain networks are designed to provide a secure and transparent way to record and track transactions, ensuring the integrity and immutability of data.

Proof-of-work is a consensus mechanism that requires miners to solve complex mathematical problems to validate transactions and add new blocks to the blockchain.

Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code, ensuring automatic execution and enforcement of contractual obligations.

Hyperledger Fabric is a blockchain platform designed specifically for enterprise use, providing features such as modularity, scalability, and permissioned access control.

Scalability is a major challenge for blockchain networks, as the increasing number of transactions can lead to slower processing times and network congestion.

Cardano is a blockchain platform that utilizes a proof-of-stake consensus mechanism, where validators are selected based on the amount of cryptocurrency they hold.

Blockchain explorers are tools that allow users to search and view blockchain data, including transaction history, block information, and wallet addresses.

Ethereum is a blockchain platform that is specifically designed to support the development and execution of decentralized applications (dApps).

51% attacks are a major security concern for blockchain networks, as an attacker who controls more than 50% of the network's computing power can manipulate the blockchain and potentially reverse transactions.

EOS is a blockchain platform that utilizes a proof-of-authority consensus mechanism, where a limited number of trusted validators are responsible for validating transactions.

Blockchain wallets are digital wallets that allow users to store and manage their cryptocurrency, including sending, receiving, and tracking transactions.

IOTA is a blockchain platform that utilizes a directed acyclic graph (DAG) data structure, which allows for faster transaction processing and scalability.
