Hashrate
Measure of the speed of blockchain miners
The proof-of-work distributed computing schemes, including Bitcoin, frequently use cryptographic hashes as a proof-of-work algorithm. Hashrate is a measure of the total computational power of all participating nodes expressed in units of hash calculations per second. The hash/second units are small, so usually multiples are used, for large networks the preferred unit is terahash (1 trillion hashes), for example, in 2023 the Bitcoin hashrate was about 300,000,000 terahashes per second (that is 300 exahashes or 
01Impact on network security
A higher hashrate signifies a stronger and more secure blockchain network. Increased computational power dedicated to mining operations acts as a defense mechanism, making it more challenging for malicious entities to disrupt network operations. It serves as a barrier against potential attacks, particularly the significant concern of a 51% attack.
02Mining difficulty
Mining difficulty, intrinsically connected to hashrate, indicates the challenge miners face in producing a hash lower than the target hash. It is purposefully designed to adjust periodically, ensuring a consistent addition of blocks to the blockchain.
