Nodes
Nodes are the foundation of blockchain technology, acting as a distributed network that maintains a decentralized ledger.
When a new block of transactions is created, it is broadcast across all nodes, allowing each one to update its copy of the blockchain.
This ensures consistency and transparency throughout the network. Nodes also validate transactions to maintain a secure and synchronized blockchain.
Miners
An ASIC miner (Application-Specific Integrated Circuit miner) is a specialized piece of hardware designed exclusively for mining cryptocurrencies.
Unlike general-purpose processors or GPUs, ASIC miners are built to perform one function with extreme efficiency: solving cryptographic puzzles required for blockchain transactions.
Each ASIC miner is tailored to a specific algorithm, such as SHA-256 for Bitcoin mining.
Because of their optimized design, ASIC miners offer significantly higher processing power and energy efficiency than general hardware.
