7.5 Transaction Fees
Simple Definition
Charges paid to network validators or miners for processing and confirming cryptocurrency transactions.
Real-World Analogy
Like paying postage to send a package, transaction fees compensate network participants for processing and securing blockchain transactions.
Advanced Definition
Transaction fees are payments made by users to cryptocurrency network participants (miners or validators) to prioritize and process their transactions. These fees incentivize network security, manage network congestion, and compensate computational resources used in transaction validation.
Technical Implementation
Transaction fee mechanisms include:
Dynamic fee calculation
Network congestion adjustment
Miner incentive structures
Key Benefits and Risks
Benefits:
Supports network security
Manages network congestion
Incentivizes network participation
Risks:

Simple Definition
A security mechanism requiring multiple private key signatures to authorize a cryptocurrency transaction.
Real-World Analogy
Like a bank vault requiring multiple keys from different managers to open, multi-signature ensures distributed authorization for transactions.
Advanced Definition
Multi-signature (multisig) is a advanced security protocol that requires multiple independent private key signatures to authorize a cryptocurrency transaction. This mechanism provides enhanced security by distributing transaction approval across multiple parties or devices.
Technical Implementation
Multisig configurations include:
M-of-N signature requirements
Distributed key management
Collaborative transaction authorization
Key Benefits and Risks
Benefits:
