Overview
Block time varies significantly between different blockchains. It is a key factor in determining the speed and throughput of the network.
Examples
- Bitcoin: Approximately 10 minutes.
- Ethereum: Approximately 12-15 seconds.
- Solana: Less than 1 second.
Adjustment
In PoW networks, the 'difficulty' of the mining puzzle is automatically adjusted to keep the block time consistent regardless of the total hash rate of the network.
