Explanation
The mining hash rate is a crucial security metric. The more hashing (computing) power in the network, the greater it is security and overall resistance to attack. Although Bitcoin’s exact hashing power is unknown, it can be estimated from the number of blocks being mined and the current block difficulty.
Notes
Daily numbers (raw values) may periodically rise or drop due to the randomness of block discovery: even with a hashing power constant, the number of blocks mined can vary in the day. Our analysts have found that looking at a 7-day average better represents the underlying power.
Methodology
Each Bitcoin node builds its version of the mempool by connecting to the Bitcoin network. The mempool content is aggregated from a few instances of up-to-date Bitcoin nodes maintained by the Blockchain.com engineering team; this way, we gather as much information as possible to provide accurate mempool metrics.
