Hash Rate
Hash rate measures the total computing power securing a proof-of-work blockchain, expressed in hashes per second. A higher hash rate makes attacking the network more expensive and is read as a security indicator.
Bitcoin miners race to find a valid block hash; the network's combined attempts per second is the hash rate (measured today in exahashes — quintillions — per second). The protocol adjusts mining difficulty every 2,016 blocks (~2 weeks) so blocks keep arriving roughly every 10 minutes regardless of how much hardware joins.

- Bitcoin Halving
- The bitcoin halving is a pre-programmed event roughly every four years (210,000 blocks) that cuts the new bitcoin issued to miners per block in half, slowing supply growth until the 21 million cap is reached.
- Satoshi (sat)
- A satoshi is the smallest unit of bitcoin — one hundred-millionth of one BTC (0.00000001 BTC). There are 100,000,000 satoshis in every bitcoin, making small everyday amounts practical to price.
