What is Hash Rate?
Hash rate measures how many hashes per second the network's miners (or a single miner) are performing. Higher network hash rate makes Proof of Work attacks more expensive and the chain more secure.
Why Hash Rate matters
Understanding Hash Rate is part of building a solid mental model of how Bitcoin, blockchain and Web3 systems actually work. Concepts in the Bitcoin category sit at the foundation of the broader stack — get them right and the rest is far easier.
