Before revision: Difficulty algorithms are a fundamental component of Proof-of-Work blockchains, aimed at maintaining stable block production times by dynamically adjusting the network difficulty in response to the miners' constantly changing computational power.
After revision: Difficulty algorithms are a fundamental component of Proof-of-Work blockchains, difficulty algorithms serve the crucial purpose of maintaining a stable transaction throughput by dynamically adjusting the network difficulty in response to the miners' constantly changing computational power.
