Algorithm and Difficulty Adjustment

CKB uses the NC-MAX consensus, an advancement of the Nakamoto consensus, with the independently developed mining algorithm, Eaglesong.

Introductions to the Eaglesong algorithm:

• Introducing Eaglesong, Nervos’s New Hash Function for CKB Proof-of-Work
• Nervos RFC 0010 Eaglesong
• Rust Library on Github

Mining difficulty adjusts with each Epoch

An epoch is a period of time for a set of blocks.

, approximately every 4 hours. The adjustment covers:

• Current block time adjustment range: 8s ~ 48s
• Target uncle block rate: 2.5%
